THE DEFALCO'S DRAUGHT BEER PRIMER
--Over the past dozen or so years we have seen more homebrewers leave
the hobby over the tedium of bottle washing more than any other single
factor. Let's face it, the novelty and excitement of the new hobby lasts
about as long as it takes to clean up, de-label, sanitize, and rinse those
first couple of cases of beer bottles. Suddenly it occurs to you, "Hey,
this is work!" After you get the routine down, it's not quite so bad,
but still it's no fun. Some of us even develop "bottle-phobia," and we'll
postpone bottling beer for weeks and weeks just because we can't bring
ourselves to go through yet another bottle washing session. Kegging beer
is the natural remedy to this dreaded disease. I'll try to briefly outline
the basic kegging process.
--Step #1 is to procure your 5 gallon stainless steel soda canisters.
These may be purchased from your friendly local homebrew shop or scrounged
through a restaurant or bar business. Once upon a time, commercial establishments
receive syrup in these containers. One of the first tasks is to eliminate
the residual odor left behind by the syrup. A thorough cleaning is a good
start but usually doesn't completely do the job. Not to worry, as you
can replace the large "0" ring on the lid and get rid of almost all residual
smell. --Note that there are two different styles of soda canisters.
Coca Cola uses what we call "pin-lock fittings" and most other brands
use what we call "ball-lock fittings." The kegs appear to be very
similar at first glance, but upon closer inspection you will notice some
apparent differences in the type of posts used. The Coke kegs have both
posts at one side on top of the canister (one has two small pins and the
other has three small pins on the posts). The other kind, General Beverage,
have the posts opposite each other on top with no pins at all. We can't
honestly say that one type is superior to the other, but if you start
with one style you will likely want to stick with it. The different styles
require different types of quick-disconnects, although these "Q-D's" are
fitted with identical threading, so you may swap them out if you have
both kinds of kegs. Also, note that the General Beverage canisters tend
to be slimmer and slightly taller than Coke canisters, so if space restrictions
are a consideration, keep that in mind.
--Step #2 is to clean the keg. In order to do this you must first release
any pressure that still may be in the keg. Hopefully your kegs will come
equipped with a pressure release valve and pull ring (this is much more
common on ball-lock kegs). This would certainly simplify things, as all
you have to do is pull on the ring and hold it until all of the hissing
is finished. If your keg is not equipped with a manual relief valve, then
you'll have to release the pressure through the "gas in" post. With a
small screwdriver, depress the center, inner spring-loaded part of the
"in" post. This post will be clearly marked on the "ball-lock" Pepsi or
General Beverage canisters and will be the two-pin post on the Coke canisters.
Get it right the first time, as a mistake can easily result in a face
covered with soda syrup or beer sediment. After all the pressure has been
relieved, you may now open up the lid and lift it out. Several rinses
with hot tap water will take care of most of the gunk inside. A nylon
or stainless steel scrubbing pad will speed up the cleaning process. (The
Frugal Brewer from D.C. suggests a toilet brush...We suggest insisting
on a new one!!!). After the keg is meticulously clean, it is time to sanitize
it. Add either 5 tablespoons of B-Brite (or 1 tablespoon of Iodophor)
and fill the keg up with hot tap water or alternately add 1/2 cup chlorine
bleach and fill up with cold tap water. A word of caution is in order
here: CHLORINE BLEACH ATTACKS STAINLESS STEEL - DO NOT EXCEED AN
OUNCE OF BLEACH PER GALLON OF WATER AND ESPECIALLY DO NOT LEAVE THIS SANITIZING
SOLUTION IN THE KEG OVERNIGHT!! --After you have filled the keg
up with sanitizing solution, affix lid and pressurize. Now, depress the
inner part of the "out" post with a screwdriver. This will fill the pick-up
tube with the sanitizing solution. Turn keg on its side and repeat process
with the "in" post. Allow the solution to stay in contact for about 10
minutes, then discard. Now fill the keg up with hot tap water to rinse
out the sanitizer. Repeat the above process with the rinse solution to
rinse both tubes. Discard this rinse solution and give the keg a couple
of additional rinses with hot water. I've been known to use my bottle
washer for this. I hold the keg over the washer and activate the "trigger"
with my free hand.
--Now you are ready for Step #3: transferring your beer into the keg.
The simplest way to do this is to syphon the beer from the secondary into
the keg, just like bottling (only easier and quicker). Instead of using
glass carboys, some homebrewers have been known to cut 1/2" to 1" off
the pick-up tubes and then use these canisters as secondary fermenters.
An airlock can be made by hooking up the "in" post to a short length of
tubing and immersing the end of the tubing in a jar of sanitizing solution.
We strongly recommend that you "pop" some CO2 onto the beer after you
transfer, and before hooking up the "air-lock." This is to insure that
the lid will seat properly and all gas must escape through the air lock
rather than around the lid. When you need to transfer the beer from the
secondary canister to the serving canister, simply rig up a "jumper tube"
that goes from one "out" post to the other. The beer is pushed out of
the secondary with a little CO2 pressure while bleeding off the the pressure
slightly (using the relief valve or "in" post) on the receiving canister.
The result will be a little lower pressure in the receiving canister,
causing the beer to flow from the secondary to the receiving canister.
Don't bleed off the gas too fast or it will cause the beer to foam in
the receiving canister and spew out the "in" post or relief valve. The
whole idea here is to minimize exposure of the beer to it's arch-enemy:
air. The shortened tube will reduce the amount of sediment picked up during
the transfer.
--Step #4: Standard practice at this point is to either: add the priming
sugar in the keg (1/4 to 1/2 cup for 5 gallons) or "force-carbonate" the
beer (see below). If you are going from keg to keg, I suggest you add
the priming sugar to the receiving keg first, and then "purge" the keg
of as much air as possible by hooking up your CO2 tank to the "out" post
of the canister and bleeding off the pressure through the relief valve
or "in" post. CO2, being heavier than air will tend to blanket the bottom
and help push the air out the "in" post or relief valve. Now transfer
your beer. If you are syphoning, add the priming sugar (a simple syrup
is nice, but not necessary) and syphon your beer on top. Once the keg
is full, re-seat the lid on top and pull the bail down. Make sure the
lid is perfectly lined up and is not skewed off to one side or the other,
as this can cause leakage. Now comes an important step: Once the beer
and priming sugar are in the keg and it is sealed off, hook up your CO2
tank and "pop" some pressure in the keg. This will seat the lid well and
minimize problems with small leaks. Personally, I prefer to hook up the
CO2 to the "out" post while bleeding some pressure off the relief valve
and/or "in" post. Again this is to purge out as much air as possible while
blanketing the brew with C02. After a few seconds of bleeding off, I let
go and allow the CO2 to continue to gurgle up through the beer for a minute
or so before disconnecting. This will insure a good, tight seal.
--Step #5: Now that your beer is sealed up, all that remains to do is
to store the keg at normal conditioning temperatures for the usual amount
of time. Once it is properly matured, you have only to chill it down and
hook up the CO2 tank to the "in" post, adjust the dispensing pressure
to 10 - 15 psi, then attach the faucet tapper to the "out" post. Here
you have another choice to make: Do you wish to drill a hole in the refrigerator
door and mount a metal shank and faucet or will a simple "picnic" tapper
suffice? Some people are reluctant to drill holes in their fridge, plus
the door mount set-up costs significantly more than the simple hand tapper.
The hand tapper is obviously more portable, but the door tap is more convenient.
Another decision is whether or not to keep the C02 tank inside or outside
the fridge. If you keep it inside, you will not need to drill yet another
hole in the side of the fridge. By keeping the tank and regulator on the
outside you will leave more space on the inside for another keg, and by
keeping the regulator out of the cool, moist environment you may prolong
its useful lifespan.
--The first glass or so you draw may be cloudy and you may wish to discard
it. But if you've done a good job clarifying the beer before kegging it,
this should not be major problem. If the beer is way too fizzy, bleed
the excess pressure with the relief valve pull ring or by depressing the
"in" post. After a little practice, you'll get the hang of it... it's
really not difficult. Lately, our kegging customers are increasingly by-passing
the priming stage entirely by "force carbonating" the beer. This is accomplished
by omitting the priming sugar after the beer has been transfered into
the keg, and then chilling the beer down as cold as you can possibly get
it (without freezing it, of course!). Now crank up your regulator to 30
psi and attach the gas to the "out" post on the keg. It should start gurgling
immediately. Now comes the fun part: start rocking the canister back and
forth for three to five minutes. The shaking action allows the CO2 to
be absorbed into solution more rapidly than if you simply hooked it up
and left it alone. After the 3 to 5 minute period is up, re-chill the
beer overnight. The next day bleed off any excess head pressure that may
still be left and hook up the keg system in the normal fashion(Remember
to re-adjust the dispensing pressure to 10 - 15 psi). The advantages of
this method are obvious: 1) it's quick, in 48 hours you have carbonated
beer, 2) it's easy to control the amount of carbonation simply by adjusting
the force carbonating pressure and time, and 3) it does not produce any
yeast sediment. To each their own. I guess. Some people just wouldn't
consider this "natural."
--Step #6: Many people who keg their own beer like to have a few bottles
for competitions, tasters, saving for longer maturation, etc. By far and
away, the easiest way to do this is to first dose each bottle with a measured
amount of corn sugar (initially try a rounded 1/2 tsp. per 12 oz. bottle,
3/4 tsp. per 16 oz. bottle, and a rounded tsp. per champagne bottle or
22 oz. beer bottle - slightly more if you prefer dried malt extract).
Using a funnel, spoon in the priming sugar. Now syphon the beer onto the
priming sugar using your standard bottling techniques. Cap the bottle
and give it a little shake to dissolve the priming sugar. After you've
finished the bottling part, simply syphon the balance of the beer into
the keg and proceed normally. What happens if you've already kegged the
beer and you decide that you want to bottle some? This is not a problem
if you have a counter-pressure bottle filler (ask us about assembling
or purchasing and using one). Without one of these little gems, you will
have to fake it using a "poor man's" counter-pressure bottle filler. To
construct one of these handy little gadgets, all you need is a plastic
hand "picnic" tapper onto which you attach about two inches of 3/8" ID
plastic hose to the "faucet" part of the tapper. Now attach a 12" - 15"
length of copper or rigid plastic tubing fitted with #2 drilled rubber
stopper to the open end of the flexible tubing. You are now ready to fill
bottles! First, you need to slide the rubber stopper up or down so that
when inserted into the bottle, the rigid tube goes almost to the bottom
of the bottle while at the same time the stopper snugs securely around
the lip of the bottle. Now open the tapper full blast to the "locked"
open position. Initially, the beer should flow freely until the bottle
is about halfway full or so. Gradually, as the pressure in the bottle
builds up to nearly to same as in the keg, the flow will virtually stop.
Now, "pinch" the rubber stopper around the lip of the bottle to "burp"
a little pressure off in the bottle. Now the beer should flow again, (if
slowly). Keep "burping" the stopper until the bottle nearly full. Now
return the tapper lever to the "off' position, and remove the filler,
and cap.
--All this talk of bottling has made my bottle-phobia act up again. If
you're like most of us keggers, you'll soon break out in sweat at the
prospect of washing another bottle. Fortunately, those days are almost
behind you now!
