The Complete Tips, Techniques and Gadgets of a Phantom Brewer
|
|
The Falcons have a long tradition of anonymous authors dropping their knowledge in the
Brews & News. The most recent addition to this list is none other than the Phantom Brewer.
TPB's mission is to bring you the simple tips and techniques that every brewer has in their
arsenal, but aren't prepared to write a full article covering them. Some of these ideas come
straight from the Phantom's own brewing practices, others are gleefully stolen or borrowed
from other brewers (including non-Falcons), amateur and professional. If you have a suggestion
for topic or a tip for the Phantom, drop the ghost a line at phantom at maltosefalcons.com.

2006 October - Hoppier Extract Beer
|
|
Extract Beers Not Hoppy Enough? Here’s some
tips for getting more IBU’s into your IPA’s
Use a Bigger Kettle, or Multiple Kettles.
Many extract brewers perform a partial-volume boil.
This is where only a portion of the full volume of
wort is boiled. Then, in the fermenter, water is
added to “top-up” to your desired volume. The
problem is that by diluting the wort you are not only
reducing the original gravity, but also the bittering
compounds dissolved in your wort. Keep in mind
that if your goal is a finished beer with 45 IBU’s,
and you’re only boiling half of your final volume,
you’ll need to create a wort with 90 IBU’s! If you
don’t have a kettle big enough for a full-volume boil,
try splitting your batch between two kettles.
Boil the Hops First
The more dense the wort, the less soluble the alpha-
acids (bittering compounds) will be. In other
words, if you boil a lower gravity wort, you’ll be able
to get more bitterness out of the same quantity of
hops. Don’t use all of your extract for the entire
boil. Instead boil 1/2 or 2/3 of your extract for 45
minutes, with your bittering hops. Then add the last
portion of your extract for the last 15 minutes of the
boil. If you can keep your wort under 1.050 for the
majority of your boil, you’ll get much better utilization
from your hops.
Use Pellets
Hop pellets are whole hop cones that have been
pulverized and pressed into those little tube-like
shapes. This process ruptures the lupulin glands,
which contain the bittering compounds, and makes
them dissolve faster and more readily. Again this
means better utilization. Also, whole hops tend to
soak up your wort and hold onto it – leaving you
with less volume in your fermenter…and less beer
for you to drink!

2006 March - Keg Hopping
|
|
For those about to hop…..
Pale Ales, IPA, Imperial IPA and any other beer
that you want to have that great nose and aroma
of hops can be done in secondary fermentation.
The problem is most brewers use a glass carboy
for the secondary. The difficulty has always been
how to get the hops in the carboy and the beer out
of the carboy. The hops need to be in a bag or
they can clog the racking cane. The Phantom
Brewer no longer suffers from this affliction. The
Phantom Brewer found the Sure Screen. The
Sure Screen is a stainless steel mesh screen that
attaches to the bottom of the racking cane. You
can add whole hops to the secondary and after
two weeks or so use the Sure Screen and rack off
the hoppy beer. The screen holds the hops in and
lets the beer out.
An additional use for the Sure Screen is to install it
on the bottom of the output tube of a corny keg.
You can then freely add whole hops right into the
keg. This makes for a very hoppy beer, perfect for
the Imperial IPA everyone loves. One warning,
USE WHOLE HOPS, You can clog the screen with
pellets. I have installed the screen on my racking
cane and two kegs. I no longer fear

2006 February - Tip Potpourri
|
|
The Phantom Brewer outsourced this month:
Adding Rice Hulls when using a cooler as a mash tun. I pre-heat
my tun with hot water so as to have a thermal mass close to zero
when adding my strike water. If you are worried about the hulls
affecting the amount of strike water needed, you should add
them into this pre-heat water. After you drain the pre-heat water,
you have pre-soaked hulls and a warm tun.
Keeping the magentic stir bar in your flask when pouring out a
starter: When I go to pitch a starter from my flask that has been
spinning on my stir plate, I will hold a piece of metal between
my hand and the flask to hold the stir bar in place and not end up
pouring it into the carboy. This way I dont have to pour too carefully
or dig around in the yeast cake for the stir bar later.
(Richard Sloan, XXL brewing, San Diego)
Seems like many brewers forget to sterilize their caps when bottling
-- this is bad. One trick to make this easier is to have a
separate, small container nearby filled with sanitized water to
keep your caps in. Another trick is just to wrap your caps up in
tinfoil and toss the bundle into the bottling bucket.
For those of you who use a counterflow chiller, you can use the
escaping water to clean out your mashtun and other tools. Not
only is it good for the environment, it saves you money! (Jonny)
And keeping an Isopropyl spray bottle around like the pros for
surface sanitation. Just spritz any openings or equipment your
grubby paws come in contact with to neutralize the little bastards.

2006 January - Batch Sparging
|
|
The longer you brew, the more technical you tend to get.
Immersion chillers? That's for beginners. More and more
brewers (especially us gadget crazy Falcons) are opting not
just for counterflow devices, but for mini plate style heatexchangers,
just like the pros use (only minus all that glycol).
Therminators for all! Hydrometers? Get a refractometer.
Glass Carboys? I'll take my conical in Stainless Steel,
please. And on and on it goes until many of us have a full
working small scale brewery sitting in the backyard. And
some aren't so small! The point is, as your enthusiasm for
homebrewing increases, so does the complexity of your
system, and probably the complexity of your various techniques.
And of course, along with more money comes
more time.
How about we take a step backwards and try something
simpler? In this case, Batch Sparging. If you have ever
been to a shop brew or brewed a batch of all-grain beer,
you are (probably) familiar with fly sparging. This technique,
developed in Britain around a century ago, is where
you gently rinse the grains post-voraluf with new water at
the same rate that you are running the wort off into the
kettle. Slow and steady is the name of the game, for the
slower your sparge, the more sugar you will be able to extract
from the mash. Batch Sparging is the opposite of fly
(or continuous) sparging. Once you are done recirculating
your mash, open up the valve and let her rip! The idea is to
drain the mash tun as quickly as possible. Then, you refill
the mashtun with new water, give it a stir, let it sit for a bit,
restir and then once again drain the tun as fast as you can.
Essentially, you are doing a parti-gyle and then immediately
combining the two run offs.
Besides a reduction in time, Batch Sparging has a couple of
other benefits. One is that you never have to worry about
mash pH since the grains' buffering ability is not being
continuously diluted like it would be in a fly sparge. Another
benefit is that you can essentially skip Mashing Out
since the liquid will get into the kettle so quickly the heat
will denature any enzymes present. Drawbacks? Depending
on your system, you will probably see a reduction in
efficiency, but some brewers actually claim better extraction
rates from Batching. Also, remember, grain costs
about a dollar a pound, so just toss in some more. Is an
extra buck per batch worth a one hour reduction in time?
Probably. And best of all, you can use your existing equipment.
And throw out your sparge-ring.
Keys to a Successful Batch Sparge:
- Mash at the usual ratio -- slightly more than 1 quart per
pound of grain.
- Due to grain absorption, you will need to add additional
water to the Mash Tun before the first runoff. So if you are
mashing 5 gallons of water, two of those gallon will be absorbed
by the grain, so you will need to add the two lost gallons
back.
- You still need to perform a vourlaf -- on both mashes.

2005 December - Cold Pitching Yeast
|
|
If you harvest and reuse yeast from your fermenter, you
should try cold pitching. This is done by pitching the yeast
directly from refrigerated storage, into wort that has been
cooled to about 4-5 degrees below the optimal temperature
for the yeast strain and beer style. Cold pitching can give you
shorter lag times, more vigorous fermentation and more complete
attenuation.
When harvesting yeast from the fermenter, leave a small
amount of beer behind, then swirl to re-suspend the yeast in
the liquid, and carefully pour into a sanitized growler or other
glass vessel. Cap and place into the fridge. You want to
keep the yeast at about 34° F. Cold enough to virtually stop
autolysis (when the enzymes in dead cells begin breaking
down the cell structure), but not cold enough to freeze.
When pitching, some elect to pour off most of the beer, leaving
only enough to rouse the yeast, others pitch the whole
works. The yeast quickly warm up to the wort temp, and
start taking in oxygen and nutrients, so be sure to oxygenate
as well as you can. The activity from the respiration phase
and beginning fermentation will raise the wort the remaining
few degrees to your optimum temp.
Don't have harvested yeast? You can also use cold
pitching with a starter. Grow it up as usual,
allowing an extra day or two for refrigeration and settling.

2005 November - Stealing The Wort For Your Starter
|
|
If you are a Falcon, odds are you brew often. Odds are even better
that when you do brew, you make sure you have enough viable
yeast to give your creation the best chance possible. Unless your
roommate is the head brewer at BJs, this entails making a starter.
And, since you're a Falcon you are going to want to step that
starter up once -- possibly twice if you're doing a big lager. That's
two to three hours out of your week when you could be with your
family/feverishly refining your next recipe. But the Phantom
Brewer has a trick for you. Steal the wort -- from yourself.
Those of us with pressure cookers often brew up a 5 gallon batch
of hopless wort which is then pressure canned and sterilized and
stored at room temperature for a series of starters sometime down
the road. But if you're already brewing beer, why not just snatch a
pint or two of the sweet stuff and use that? You can even use pint
glasses if you like. During the lauter run-off, when the beer gets
down to around 1.045, redirect the hose into a vessel to collect a
few pints. If your starter is intended for a larger brew, start the
theft at around 1.060.
If you already have a starter going, stick the stolen and covered
wort in the freezer for thirty minutes -- Don't forget about it --
and then simply add it. If you are starting from scratch simply add
yeast. And if you are not going to be needing a starter for a little
while, stick it in a mason jar and stick it in the fridge for later. It's
that simple. To make up for the lost gravity, boil the beer for 10
minutes longer.

2005 October - CO2 Powered Bottling
|
|
Who likes lifting heavy things? Right, so why lift, when you can
simply turn on the gas? In his article on CO2 racking, Falcons'
President Drew described how you can use CO2 to move your beer from
Carboy to Carboy (or keg to keg). But why stop there? Let CO2 assist
you when it comes time to bottle.
What you need; you probably already have 90% of what you need if you
have a CO2 setup:
- CO2 tank
- Standard out-hose -- 1/4" inner diameter (id)
- 2' of 3/8 id tubing
- Bottle filler (get a good heavy duty one – John sells "Phil's
Philler – recommended)
- Screw-tight hose clamp
- 1/4" to 3/8" reducer-bard (this simply allows you to make the 1/4"
hose talk to the 3/8" hose)
This process is even easier if you secondary your beer in 5 gallon
cornies. Even if you don't, you can achieve the desired results by
using a corny as a bottling bucket.
Setup as if you were going to move beer out of the keg using CO2;
standard keg to keg transfer. But, instead of connecting to another
keg, plug in the ¼" end of the reducer-barb to the beer line. Attach
the 3/8" tubing to the other 3/8" end of the barb. You don't need a
clamp here, as the barbs will hold. Jam the bottle filler into the
other end of the 3/8" tubing. Secure it with the clamp. Now you are
ready to bottle.
The Phantom Brewer recommends no more than 10 psi – use 3 psi if you
are bottling out of a glass carboy. You will find that the CO2 fills
the bottles about three times as quickly as gravity, and you don't
have to lift or move a thing. Foaming is normal – you will lose a
minute amount of beer.

2005 September - Portable CO2 and Beer Service
|
|
Summer time and the beer's flowing freely; or at least it will if you remember this Phantom Brewer's Tip.
It's that time of year, friends are having parties; there's food on the grill; children splashing around in the pool and beer needing to be tapped. Having our beer on tap at home is a breeze, just go and fill some pitchers or get the guys (and gals) to gather around the taps whenever they'd like a beer. Mobile beer service is a whole other story. Growlers just don't cut the same fine jib that a bringing a keg does, but who wants to lug that CO2 bottle around and how do you keep it cold?
If you're a gadget junkie, Daume has a few items on sale that will meet your needs, including a cycling inspired cartridge based injector system. Downside with those is the expense of the cartridges and the number you need to dispense a keg. The cheap trick is to use an empty keg. Blast a clean, empty keg with 30psi until the gas stops flowing. Using the gas keg and a jumper line (hose with two gas in fittings on it), you can give a lethargic keg a shot of CO2. Like the cartridge injectors, the pressure won't be regulated out of the keg, but it's an easy solution to the problem.
The other trick of mobile beer service: how do you keep the beer cold? Most of us can't afford or need a jockey box or cold plate arrangement, see the Club's front bar for an example. Coolers and buckets don't cover the whole keg, trash bags don't work, foam boxes leak, etc. What to do? TPB suggests taking a lead from Richard "Beanie" Webster: repurpose Daume's old extract canisters. With your favorite cutting implement cut around the lip of the canister top (the side with the spigot). Leaving the top portion of the lip intact and knocking out the top side leaves you with a perfectly sized and leak-proof container to hold a keg and ice. For extended cooling time, wrap the container with moving blankets or other insulation and secure in place with bungee cords or other means.
There you have it. Easy portable beer service. With a little creativity, you could refit the lid (with tabs) and set it up to have a tower to make all your friends, oh and ahh even more.
If you have other suggestions for portable beer service (lots of parties!), let the Phantom know. (phantom@maltosefalcons.com) Other ideas are needed! Tell the Phantom the things you've made or the questions you have. The Phantom knows!

2005 July - A Tip To Help Prevent Boilovers
|
|
A good rolling boil is important for a good beer.
Lots of good stuff happens during the boil. Volatile,
smelly sulfur compounds are expelled from
the beer. Other compounds, alpha acids, that bitter
our beer are only extracted by boiling. But get
too vigorous a boil going, and you'll slop wort all
over the place. Instead, try using your marbles.
That's right, glass marbles, the kind kids play with.
Just put about 20 of them in the brew pot. Don't
worry about the marbles breaking. There're made
of tempered glass and their spherical shape gives
them great strength. That's why kids can bang
them together day after day and they don't break.
Don't worry about the heat, either. A few hundred
degrees Fahrenheit is nothing to a tempered glass
marble.
Instead of getting big, explosive gas bubbles popping
up and blowing beer out of the kettle, you'll
see a bunch of smaller, finer bubbles evenly
spread over the center of the boil. This steady
stream of smaller bubbles will do just as good a
job of breaking up the hop resin and oil bubbles in
your wort -- without the sloppy mess.
A Phantom Brewer had this problem early on and
greatly smoothed out the boiling by adding about
20 glass marlbes to our 15 gallon brew pot.

The Phantom thanks Sal Sciortino for retaining
enough marbles to pass this tip on!

2005 June - Clean That Kettle
|
|
Beerstone. No matter how much you much how you squeeze it, you'll never
get beer from it. Beerstone, the colloquial term for calcium oxalate and water salts, is the ugly
brown coating that grabs hold of the inside of your shiny brewpot. Not only is beerstone
unattractive; it affects the performance of your kettle. Remember a clean brewery is a good
brewery.
Now the Phantom has seen many brewers laying into their kettles hard
with a scrub pad to remove that stone. My fellow brewers to borrow from Dupont, "Better ways for
better living through chemistry." Unlike organic by-products of brewing, proteins, hops, etc.;
beerstone doesn't clean easily with alkaline chemicals (soap, detergent, caustic, PBW). After a light scrub to remove organic residue, the cleaning agent of choice is an acid wash.
Myriad choices exist for the brewer with different effects. Yet the
basic process remains the same: an acid salt or liquid is mixed into hot water. The solution sits
in contact with the stone for 10 minutes (soak directly or apply via a sponge). A soft sponge can
then be run around the kettle and the beerstone will peel right off, exposing the bright shiny
stainless steel underneath. Rinse with hot water To protect the kettle, you need to passivate the
steel. With solutions of citric acid or vinegar, the cheap acid washes, you need to let the kettle
sit dry exposed to the air for a week before use. Professional acid washes (including the Acid 5
solution at Daume's) include acids that will passivate the steel quickly.
Rescue those kettles from the grip of the notorious brown! Give them
acid and bring them to the bright and shiny enlightened path.

2005 May - Organizing Your Brew
|
|
Something funny seems to happen when brewers get
to the boil, they get distracted and disorganized. The
Phantom’s seen it happen to many a brew partner and
himself, so this month’s tips are some simple techniques
to fight the fog of brewing.
- Keep Notes! – TPB doesn’t care how you do it:
Promash; notebook; index cards; bubble gum
wrappers. If you can take notes and look back
you’ll know exactly what you did right. You don’t
do anything wrong, right?
- Make a checklist. It seems silly, but you’ve got a
computer or a notebook. Put all the the things you
need to accomplish with times and check them off.
- Organize your boil
- Lay down some foil and mark it with your
boil checkpoints (60, 20, 0, etc). Place
your hop additions, irish moss, minerals in
each of the slots and work left to right.
- Label a set of cups with your boil time and
fill each of them with the appropriate hops
and chemicals. This is really great since
you can ask your wife or girlfriend to
throw the “yellow” cup or the cup with
“20” on it when you’re busy cleaning carboys.
This has saved the Phantom some
effort in the past.
TPB would like to thank Todd Bissell of Foam on the
Brain for instigating this tip with his suggestions. Remember
if you have a simple idea or tip email phantom@maltosefalcons.com.

2005 March - Draining Carboys Fast
|
|
TPB brings you two tips this month, both to help you
get those carboys empty quick by avoiding the glugs.
Those pressure equalizing bubbles of air slow down the
voiding of liquid. So to speed up the flow, you must
provide air to the interior of the carboy.
The Racking Cane – This is the classic alternate
use of everyone’s racking cane. Just place and
hold the racking cane while you invert the carboy.
Move the racking cane so that it’s open in
the air bubble at the inverted base and watch
the water gush.
The Vortex – The old standby frat party trick,
the swirl can help you out here. If you have a
carboy stand, it’s even safe. Place the carboy in
its stand and start rotating it quickly. Get the
liquid moving quickly and then stop the carboy.
The liquid will keep swirling and soon a vortex
shooting air into the carboy should appear.
(This can also be done by holding the carboy in
your arms and rolling the liquid, but be careful
and don’t drop the carboy!)

2005 February - Stove-Top Stuffing
|
|
Many of us out there are forced by fate to brew
on the meager fire of an ordinary kitchen range. Far from the jet-wash inferno of a good Cajun
Cooker propane burner, ordinary stoves take forever to boil 5 gallons of liquid, and forget about
trying to step up a mash before it goes sour. There are ways around this though.
I’ve successfully stepped up mashes by running a modified
decoction on the stove. At first, I did it because the style I was making with a lot of unmalted
wheat really necessitated a protein rest, which would mean I would have to step up my mash. I
was hoping that I could start it pretty thick and add hot water and use the one burner to step it
up, but it was going too slow. I just grabbed another pot and scooped out some of the mash,
heated it real quick on a free burner and tossed it back in, hitting the step-up temperature nicely.
That Belgian Witbier took gold in competition several times over. I’ve been following a similar
mash schedule since then. With one burner I was stuck doing single infusions, but just by using two
burners, I can be considerably more versatile in what styles I can brew. Also, I always split the
boil, too so I can actually boil it, instead of barely simmering it on one burner. tpb

2005 January - A Dry Counterflow Chiller
|
|
The Phantom Brewer has seen some brewers in the club use an older technique of keeping
a counterflow chiller (CFC) clean by filling the line with sanitizer. TPB has always been
deeply troubled by this practice. The copper tubing used in chillers is sensitive to long term
acid exposure. Also, many sanitizer solutions become ideal bacterial and mold breeding
grounds as they drift from their effective pH range during long storage times. Nope, TPB
doesn’t like this one bit.
Instead, TPB would like to recommend that you go the opposite route and store your
CFCs bone dry. This will prevent the growth of mold and reduce copper patina. The most
effective way to dry your chiller is that trusty bottle of carbon dioxide you use for your
kegs. Remove whatever keg adapter you have from the line and press the gas line over
the output side of your CFC. Hit the CFC with bursts of CO2 until you’re blowing dry from
the line. All done! Remember CO2 is cheap, bad beer is expensive! tpb

2005 January - How to turn a Refrigerator into a Kegerator |
|
Thinking of turning an ordinary fridge into a kegerator?
It is cheaper and easier than you think. First, find the refrigerator. Ask family and friends
if they have an old one. If not, you can find them easily in the Recycler for about $50. The
kind with a top freezer work best. Make sure the inside dimensions of the fridge are at
least 16” deep and wide and 27” high in case you ever want to put a commercial keg inside.
Next, round up your parts. You’ll need a CO2 tank, beer regulator,
gas line, keg taps (either quick disconnect (QD) for Corny kegs or a Sanke tap to fit commercial
American brews), beer line, a beer shank(s), faucet(s), some 1/2” or 3/4” plywood, and some assorted
fittings. You want your shank(s) to be as long as possible, at least 4 or 5”. The extra
length picks up cold from the refrigerator and transfers it to the faucet, which helps to minimize foaming. All
this adds up to about $200 if you have nothing, usually less. Both the Home Wine
and Beer Shop and Draft Beer Store have everything you’ll need, except the plywood and tools.
The only tools you’ll need are a drill motor, a 1” hole saw and a wrench to tighten everything down.
Start by cutting a piece of plywood to fit the floor of the fridge. This
small step will make your kegerator last much longer and be much easier to work with. You may also
want to cut a smaller piece of plywood to go inside the door, with the beer shank(s) passed through
it, this helps stiffen things up. Use the hole saw to cut a hole through the exterior skin of the door.
If there is a butter dispenser in the door, align your shank hole(s) with it. If you’re using the plywood
backer, have an assistant hold it in place and cut through it with the hole saw, place through the
hole you cut in the exterior skin. Put the shank through the door and attach the lock nut included at the back.
Your beer line should be either 1/4" or 3/16”. It should be at least 5 ½” long, both
for foam control and ease of use. Make sure you get a “tail piece” that is the same
as your beer line, put it through the supplied hex nut, insert a washer, and attach it
to the back of the shank. As an alternative, there are shanks available that have
the barbed nipple cast in with the nipple, all in one piece. Be sure to secure the beer
line with a hose clamp.
From there, all you need to do is run the beer line
from the back of the shank to your black Cornelius QD or the top of a commercial
tap. Attach the regulator to the CO2 tank and run the gas line from the nipple at
the bottom of the regulator to the gray Cornelius QD or the side of a commercial tap. Use hose
clamps to tighten everything down. Then attach your faucet. Use a spanner wrench, they’re cheap
and will make your faucet last for years. Turn your CO2 on, adjust your pressure, hook up your
kegs, and enjoy your draft beer.
If you have any questions, John and Mark at the
Home Wine and Beer Shop or either of the Johns at the Draft Beer Store can answer your questions
and make sure you have the right fittings. tpb

2004 December - Foil Diffuser For Sparging |
|
The Phantom Brewer has been quoted in the
past saying that Aluminum Foil is duct tape for homebrewers.” This tip comes to us courtesy of
Mike Dixon out of North Carolina.
Folks have tried a lot of different devices for
evenly distributing their sparge water over the mash bed without causing channeling. There are
fancy whirligigs, turned over bowls, colanders and more. By far the simplest and cheapest
though comes from Mike, foil. Take a sheet of foil long enough to cover a good portion of the
mash bed. Poke a set of holes in the foil. Just set the foil on top of the mash bed and pour
your sparge water onto the foil. tpb

2004 November - Yeast Recovery System |
|
Those of us who brew big beers and
pitch a lot of yeast know all about blow off. That wonderful frothy head that
grows way beyond the confines of the carboy and blows through the bubbler
and gets all over the place.
The remedy you say is simple, use a blow off tube: a
large plastic tube, one end of which fits and seals directly into the top of the carboy
while the other end is put in a jar with some sanitized water in the bottom.
This will let all that extra foam and CO2 be released from the carboy and avoids
the mess.
The Yeast Recovery System is simple, just make sure that all parts,
the blow off tube, the jar, the water in the jar, and the foil to cover and partially
seal the tube into the jar are all sanitized when you put it together. All of the
foam blow off collected in the jar is pure useable yeast and can be used to start
another batch or to help ferment out the batch that it was blown from. After the
ferment stops blowing off, take the jar, cover it completely and place in the refrigerator
to allow it to settle. After a few days it should have clear liquid on
top that can be poured off and the remaining slurry can be put in a sanitized
container and kept refrigerated until needed.
This System has worked great many times, especially when used to aid
in fermenting out those last few specific gravity points to make that brew just
right. tpb

2004 October - Forced Ferment Test |
|
We’ve all had that moment of panic and doubt.
You brewed a beer that’s stuck up higher than you’d like. Was the beer just not as fermentable
as you’d thought? Maybe you mashed warm, maybe your extract is poorly fermentable or
maybe the yeast is in poor health. One important data point to obtain is the brew’s
absolute terminal gravity. In professional breweries this information is known for their brews and
the way to find it is the classic Forced Ferment Test.
To perform the test, you need a sanitized growler
or flask and a pint of wort, just after pitching the yeast is best. Ideally you should have a magnetic
stir plate (that you use for your yeast starters, right?). Place the pitched wort sample into the
growler covered with foil and stir on high for 2 or 3 days. Measure the gravity. This is your absolute
minimum terminal gravity. If you don’t have a stir plate, you should swirl the sample as often as
possible.
A ferment that is ideal for producing flavorful beer
will probably never hit this absolute gravity, but it should come within a few points. If your beer isn’t
at the end of primary you might want to consider re-pitching the brew with fresh yeast.
If you have a stuck brew, try removing a small sample
and performing a forced ferment test on it with fresh yeast and nutrient. This
will let you know if you should re-pitch the beer to bring it down further or if
the beer is high by nature.
The Phantom doesn’t do this test on every batch
of beer brewed, but if the beer is made with an unusual technique, ingredients
or a high starting gravity the results are great to have. tpb

2004 August - Getting Those Kegs Ready |
|
Kegging is one of those great Hallelujah moments
for brewers. Why would I ever go back to bottling now? But while there's only one
container to clean and sanitize, its mission critical to get the job done right.
Here's a simple method that allows you to be
sure that your kegs are clean, santized and ready to go whenever you need them. It also
has the advantage of using less cleaners and sanitizers and purging your kegs of all that
staling oxygen.
- Gather up as many kegs as you have to clean (TPB generally does this four at a
time)
- Spray each keg out with hot water to remove any of the obvious gunk.
- Every other cleaning or so, remove the posts and soak the posts, poppets, and the
gas dip tube in PBW. (Tip: Use different containers for gas and liquid fittings to
avoid confusion.)
- Fill the first keg with a scalding hot solution of PBW and run a brush through the
liquid out dip tube.
- Rinse and seal the posts and poppets back in place. Rinse and seal the keg with it's
lid.
- After 15 minutes, push the PBW out of the keg with CO2 through the liquid out using
a jumper hose. (2 liquid fittings on either end of a short piece of hose)
- Rinse out the newly empty keg and let sit upside down to drain with the lid off.
- Fill the empty keg with a 5 gallon solution of Saniclean/Starsan/Iodophor.
- Push the PBW solution out of the other keg and rinse it out.
- Using the jumper hose, push the sanitizer from the first keg into the second. Seal the
keg with CO2 and set off to the side.

2004 July - Dissolving Candi Sugar in the Boil Cleanly |
|
This tip comes to the Phantom Brewer courtesy
of Dave Mathis of BJ’s Brewhouse.
Many of us use candi sugar in our Belgian
style beers, but dissolving it in our boil kettles can be a pain. More often than
not, the crystals end up sticking to the bottom of the kettle and require vigorous
stirring to fully dissolve and incorporate into the brew.
The solution lies in that nylon hop bag you
bought long ago and never really used. Simply place your candi sugar in the bag
and tie the bag to one of you kettle handles. Drop the bag into the boil and let
it remain suspended in the brew. Come back 5 minutes later and all your sugar
will be gone! tpb

2004 June - Using a Cornelius Keg as an HLT |
|
Many home brewers don’t have the room or desire
to set up a three-tiered brewing system. Here is an easy way to eliminate the
top tier—the hot liquor tank.
When your brew is in the mash, just bring 5
or more gallons of water to a boil. You’re not using your burner anyway at this
time. Once it reaches a boil, pour it into clean keg using a large funnel (for
safety). I use 10 gallon kegs, but 5 gallons will work fine also. By the time
you have finished re-circulating the wort in your mash tun, the water will have cooled
to 175-180 degrees.
Just use CO2 to push the hot water to the top of your
lauter tun. I have a pie tin with many small holes drilled in it so I won’t
disturb my grain bed. The faucet drains into it.
Make sure your water line has clamps on both ends! Many of
us omit them on serving lines, but the tubing expands when hot, and WILL pop off,
spraying scalding hot water.
You can fill two or more kegs that way and never run
out of hot water. It comes in handy when you’re cleaning your wort chiller,
sanitizing your aerating stone, etc. An added advantage is that the boiling
water sanitizes your kegs. They’re ready to go for either fermenting or kegging.

2004 May - Cold Soaking Dark Grains To Adjust Your Beer Color |
|
It happens to all of us at some time. That
beer that you wanted brown is copper instead or maybe your stout is just a shade more
brown than black. What's a light in the color brewer to do? Do what the Germans do and
make up a homemade batch of Sinamar, which is a Weyermann malt extract product
used to adjust color.
To produce your own, soak a pound of Carafa
malt in a quart of cold water for 24 hours. Strain the mixture through cheesecloth, a fine
mesh strainer or a coffee filter. The resulting black inky mixture can be saved in a sanitized
jar for over a month.
To use your new color extract, carefully pour
a small amount into the brewpot, stir and pull a sample to look at the color. Keep adding
small amounts of colorant until satisfied.
