Subject: Drilling a fridge
On the thread concerning the safest place to drill
holes in a refrigerator....the door is generally safe,
but the side walls MAY NOT BE SAFE TO DRILL.
We had to have a service call for a refrigerator in
our house a few months ago, and I asked the repair guy
about where it would be safe to drill and he stressed
that the side walls are often not a safe place to
drill, especially at the top in models with top
freezers. I spoke to other repairmen following this
and they all said essentially the same thing.
The doors, except in those models with in-door
ice/water dispensers, are free from safety hazards.
If you drill into a freon line, don't breathe in the
fumes and trash the refrigerator because repairing a
holed freon line is just about impossible. Freon is
hazardous to your health when inhaled.
You may be able to remove the back covering and find a
safe place to drill for a gas line, but I'd avoid it
if possible. I charge my kegs and remove the gas line
until the pressure in the keg gets too low for
satisfactory carbonation levels. You can leave the
lines in place, but I don't like to since a leak can
empty a CO2 tank fairly quickly.
Having a bunch of my homebrew in kegs in a dedicated
refrigerator has got to be one of the finer things in
life...so go for it.

John,
That word you used, 'better', is quite subjective. :)
There are a good many yeast cultures available to you. But why not give a
try to the one that came in your kit? You're likely to find that a .69c
packet of dry yeast is just as capable of making a good beer as a $4.35
liquid yeast smack pack or test tube of liquid yeast.
For that 'guiness' head, I achieve that with .5 to 1 lb of wheat DME. It
might not be 'true to style' for some beers, but I'll challenge any beer
expert to detect such a small amount, and it does wonders for the heading
qualities of a beer. I've seen a 'heading liquid' sold in my local home
brew store, but I've never used it, so I can not comment on it's
effectiveness or taste impact. I'd rather add a bit of wheat malt, and let
that do the trick.
RE: Carboys & Carboy handles
Last week, I saw the bottled water van pulled up outside my company's
building, with dozens of plastic carboys sitting on top of one another, in a
milk crate sort of rectangular-cubical (if that's a word, but I think it
describes what I saw well enough) plastic container that let them be stacked
on their side from floor to ceiling of the van.
This would be, in my opinion, an excellent carboy container, since they are
designed to be just such. They had hand holds worked into their design,
which would make carboy transport _much_ easier, with absolutely zero chance
of snapping off the neck.
I tried to buy a few off of the driver, with no luck. I tried visiting 'The
Container Store', but they do not carry these containers. I've hunted on
line, but I've yet to find them. Any information the members of this forum
could provide would be appreciated, as I'm really interested in picking up a
few of these to hold my carboys.
Cheers,
Ken

Subject: Re: Stupid brewer tricks-Burnt IPA
This may sound very simplistic, but try aging the beer. The dry hopping will
cover up the taste but time will mellow the burnt flavour. Give it 3 months in
a cold storage, say 40 -45 degrees F. If that is not enough, go for 6 months.
Sounds too easy but it often works wonders. Protz!

Ah, Phil, that is an easy one - your beer gut is obviously resting on the
top of the scales leading to your 'apparent' weight being much lighter than
your 'real' weight. Now there is nothing wrong with having a bit of an
'awning over the toolshed', but you need to correct your measured weight by
dividing it by the density of alcohol.

It is obvious how quickly times have changed for you. I well remember when
you were a lithe athletic fellow. Clearly the recent hard times have left
you with too much time on your hands - drinking ! I can imagine that there
are days when you don't even bother to dress, preferring to just shuffle
about your rambling mansion wearing nothing but your old, threadbare
dressingown. A schooner in one hand and the butt end of a fag in the
other.

The trouble with triticale (and I guess tribbles) is that it may be hard to
find. Here in Florida, it is grown and used as animal feed. So you might try
looking in your local feed store (for the tritciale, that is; though maybe

Subject: Carboy anxiety . . .
Greetings to the Collective,
Don't fear the carboy; just contain the brute.
I have been a victim of one breakage. Sometime after the wound had healed ,
I was getting checked out by my dermatologist ( a must if you live in
Florida). He pointed at the scar and inquired "Gall bladder?" I replied
"Nope, carboy". But I digress. . .
I tried switching to kegs for all of my fermenting needs. The only problem
was that the beer took forever to clear up in the primary. So back to the
dreaded, potentially eviscerating carboys I went. I have never trusted them,
the orange handle, nor their bottom for that matter.
I have found that dairy crates of the metal variety make for a hardy "cage"
for carboys.
The key is to insure that the plastic bottom of the crate is in good shape.
I am planning on replacing mine with 3/4" plywood when the time comes. The
cases provide some lateral protection as they go up halfway on a 5 gallon
jug. This is important if you have more then one fermentation going under
the biscuit table in the kitchen ( mine has a 4 carboy capacity). I have an
empathy for the UBX guys as one carboy would inadvertently some in contact
w/ another with a dreaded "Ting". These crates prevent that and slide easily
across the floor as well.
I scrounged mine from the local convenience store. Check with the dairy guy
at the market. Homebrew makes for a wonderful bartering medium.

You are of course compensating for the weight of your keg?

Very interesting. I too have pondered this phenomena but it never never dawned
on me to pee in glasses. It may be that after consuming oh say, 10 liters of
beer that you may *think* you are peeing in a glass when in fact you are
"missing the mark" as they say. You might want to get some assistance- perhaps
from Mrs. Yates. If she isn't game, find a Good Friend to help. As the saying
goes, "A friend will help you move; a Good Friend will help you move a body".
Presumably, a Good Friend would also help you pee in a glass.
Also, a friendly suggestion: depending on what you brew you might want to put
those full glasses of pee out of reach. My personal philosophy is "Don't eat
yellow snow, don't drink yellow beer" so I don't think I could make the
mistake, but if yer a pilsner man, it might be hard to distinguish between a
glass you filled from your keg and a glass you filled with er.. recycled beer.
Presumably you'd discover your mistake pretty quickly (unless your beer really
sucks in the first place) but hey! why take the chance of throwing off your
experimental results!
>When I get on the scales I hardly weigh anything more than my usual weight.
>How can this be possible?
I have not found this to be the case but apparently urine mileage varies.
>There must be some residual effect because each year I am going up in weight
>by exactly my average beer consumption per night ie 15 kilos.
You better hope this trend reverses my friend. If you are gaining 15 kilos per
year, after 5 years you'll be twice the man you are today and the problem just
gets worse. The biggest problem as I see it is clearly as your size increases,
so will your beer consumption. You may be looking at a significant investment
in a higher-capacity brewery.
>Can someone shed light on this oddity?
We lose body liquid in many ways- only a small portion is through the
production of urine. We also give it off through our skin pores as well as
exhaling it. If you want to get better experimental results you should devise
a means of recovering ALL the liquid your body excretes. You might try
breathing through a tube and condensing your breath (a simple still) whilst
sitting naked in a large plastic bag that is tightly sealed around your neck,
to collect/condense the vapor given off through your skin pores. An added
benefit of doing this is you can dispense with the pee-glasses! Then at the
weigh it. I'm sure you'll still be short of 15 liters, but I'll bet you'll be
damn close.
And oh yeah, I almost forgot- your condensed breath will no doubt contain a
reasonable concentration of alcohol and should be recycled (drunk) immediately.
Good Luck,

Just about anything you can get hold of other than dry yeast will be better.
Wyeast and White Labs both make a liquid Irish Ale yeast. You
could also probably get away with most British Ale strains (I know the
Irish fought a revolution 90 years ago to get the British out of Ireland,
but I've always been a practicioner of Realpolitik ;-) ).
As far as getting a "Guiness" head on your stout, I'm afraid you're SOL
without some serious equipment. That gorgeous, creamy head is made by:
1) carbonating with 75% nitrogen & 25% CO2;
2) dispensing from the keg at 25psi (an outrageously high pressure); and 3)
using a special tap that not only is designed to stand up to that kind of
pressure but pushes the beer through a series of convolutions on its trip
through the tap, whipping the beer into that beautiful, long-lasting froth.
I, personally have never brewed a stout for precisely that reason. I'm
afraid of putting the time, effort, and money into brewing something
that will only make me sigh for what isn't there everytime I look at it.
But, I do know that others brew marvelous stouts even without the $300
worth of equipment needed to pour it in an "authentic" fashion. Good
luck and let me know how it turns out.

What a shame, and less than a week after I warned of exactly this
right here in HBD 3787:
"Not only that, but this might be a good time to repeat to newer
brewers to turn off the burner after you've brought your brewing
water to a boil and before you add your extract, especially liquid
extract.
"My first three or four beers (about 28 years ago or so) had a
scorched flavor and flakes of black bits floating in them. I
couldn't figure out what this was until I realized that when I poured
the extract in the kettle, it settled down on the hot bottom where it
scorched. Best to turn off the heat, let the pot cool a bit, stir in
the malt, and get it thoroughly dissolved before bringing back to a
boil."
And only 21 miles from 0,0 Rennerian!
Well, sadly, I have bad news for you. It never goes away. At least
from my dim recollection, it may diminish, but it mostly stays there.
I suppose you could add a "tea" from steeped chocolate and black
patent to try to cover it up and call it a porter or stout.
At least I'll bet you won't do it again, which is better than I did back then.

Subject: Re: Keg Fridge
Hello all.
Brian Lundeen asks about setting up a keg fridge. I really have no opinion
on the manifold set up. My fridge holds three kegs and the styles of beer
that I brew all end up being carbonated at about the same level (12 PSI), so
I use a valved manifold.
This post is only to offer the experience of converting my fridge. I was
very excited when I got my three taps and began to install them into the
door of my used upright fridge. I drilled a hole into the side for the gas
inlet, then drilled three holes in the door for the taps. I was careful to
measure the three holes so that they were equally spaced and placed at an
ergonomic height from the floor. I got done and stood back to admire my
work. The drip tray (a must) was low enough so that my tallest glass could
still fit under the tap. I was very proud of myself. I hooked up one of
the taps to the keg I had ready so I could enjoy my new toy. So I opened up
the upper freezer compartment to fetch a frosty glass and promptly blew beer
out the tap into the drip tray..........and then realized the tap handles
were above the parting line of the freezer and refrigerator door. Opening
up the freezer door hits the tap handles and opens them. After a few choice
words, I resigned myself to the fact that whenever the freezer door opens,
the refrigerator door needs to open as well. The other thing I learned, is
that when the refrigerator door opens, all of the plumbing from the door to
the kegs moves with the door, which isn't a big deal, but is a bit of a pain
when shuffling empty kegs out with full ones hooked up.
In the end, I wished I had put the taps out the side of the fridge. This
would have solved the problem of the refrigerator/freezer door issue, and
also would have made the plumbing from the kegs stationary which would
simplify things as well. Those of you contemplating the conversion of an
upright fridge with an upper freezer compartment, think carefully before
firing up your drills.

Liquid yeast can make a big difference. WhiteLabs and Wyeast Irish
yeasts are ideal. The new tubes from WhiteLabs are especially nice
because there is truly a pitchable amount of yeast, although it never
hurts to boost it a day or two ahead. But I've found it to be
unnecessary since I aerate heavily.
Some unasked-for additional advise - if the kit instructions tell you
to use sugar, don't. Use an equal amount of dry malt extract, or a
bit more to make up for the lower fermentability of extract compared
to sugar. I'd avoid Laaglander or similar as it is too unfermentable.
Many kits are made to appeal to brewers who want minimum cost. You
can probably afford the better quality of all malt. This is probably
the best thing you can do for improved head, too.

It may shed some light on "where it all goes".

* * *
Four main places your home brew is going:
1.. The aforementioned wee wee. Keep in mind that wee wee does not
have the same density as beer. Which is to say, a liter of wee wee will
weight more (or possibly less) than a liter of home brew. Either way,
density is probably not a significant contributor to the phenomenon in
question. It is more worth mentioning as a scientific curiosity.
However, the majority of the home brew departs in the form of future
compost. (And while we are on the subject, keep in mind that this
includes the compost in your colon, too. There is a lot of water - or
home brew - weight and volume sent there).
2.. Water vapor. I use this term loosely to describe all sorts of
things -
components of sweat (which, by the way, you do more of when you
drink), water vapor exhaled from your lungs, components of the proteins
and oil that keeps your skin soft, etc.
3.. Heat. Keep in mind that you, as a human, are a very high-powered
engine (some of us more than others). This means you have to burn lots
of stuff to keep you breathing, etc. So, some components of the home
brew serve to keep you at a level somewhere above hibernation. (Note
that this situation differs from the hibernation that results after 15
liters
of home brew.).
4.. The aforementioned weight per year increase. Everything that your
body cannot turn into heat, water vapor, or wee wee, it keeps.
Indefinitely. Sometimes, infinitely. The vast majority of the extra is in
the form of enlarged fat cells. And FYI on this one, your body would
much rather turn sugar and alcohol (i.e. homebrew) into fat than turn
protein or fiber into fat. This is because alcohol and sugar are much
easier to convert. Hence the reason that alcohol is one of the big no-
no's in the average diet. (And on a side note, homebrew actually weighs
slightly more than 1 kg per liter. Pure water is exactly 1kg/liter. The
extra "stuff" in homebrew makes it heavier.)
And for my final, non-scientific thought on why the mysterious
phenomenon occurs: I know that after 15 liters of home brew, I would
be entirely incapable of reading a scale. Or wee weeing into a glass for
that matter. Perhaps the measurements have not been made with all the
accuracy required for true scientific evaluation? ;-)

This is a great lag time (where is the lag?!?). I haven't been able to get
down that low unless the yeast are in a very active state or if I pitched
onto the yeast cake of a previous batch (barleywines excepted). I think the
lag time (at best) was somewhere around 6-8 hours when I chilled the
starters. Then again, I only know it's fermenting when the lock starts
bubbling.

There's no argument from me. I'm a firm believer in doing what works best
for you. I can't honestly say that one method made beers that tasted better
over the other. For me I prefer to pitch less and not waste the beer from
the starter.

Please note that I use the terms "heat-shock" and "cold-shock" which are
demonstrable physiological changes in the cell activity & metabolism. From
a biological standpoint, the word "stress" is used to describe the result of
a force or condition applied to an organism or system which is beyond it's
acceptable tolerances. This is not the psycological definition which
implies the mental or emotionally disruptive condition. Yeast have no
brains. But I know where you're comming from here.

Good point. Since I have no data which says yea or nay, I stick to what is
easier for me. I know that in general heat and cold shock CAN cause a
change. These may be one or many of a plethora of pheomenon ranging from
things such as physical cell wall damage to repression/enhancement of
biological pathways. It is also the mechanism by which yeast and other
single-celled organisms will adapt to their environment. Why do the cells
floc when you chill them? They're responding to an event which will
increase their chances of survival under adverse conditions.
Is it better or worse for my beer? Dunno. In general (again) it may be
detrimental. Search the Net on "temperature shock". There's a lot of info
out there. But does it all apply to brewing yeast? Again, dunno, I'd have
to study the different strains of yeast beyond the capabilities of my
basement brewery lab and generate those charts and graphs I hate so much to
know for sure. I aint doing that. My lab days are over. The brewery lab
is strictly for yeast ranching and I'm going the way of the monk. No more
experiments. Only brewing enhancements.

Jamie of PEI writes: "As it turns out, it is potent and dry. No, that's not
it. It's a genuine porch-crawler and is down right sour. Is there any way
to sweeten it up?Can I salvage it just by adding sugar or will it just keep
fermenting?"
This brings to mind something I have been thinking about for some time on
the "sweetner thread."
Has anyone ever tried using a consumer sweetener that is relatively new on
the scene. It is called "Splenda" Here is the information I have on it:
Sucralose: Also known by its trade name, Splenda, sucralose is 600 times
sweeter than sugar. It is made from sugar, chemically altered by the
removal of one hydrogen molecule and it's replacement with a chlorine
molecule. After reviewing more than 110 animal and human safety studies
conducted over 20 years, FDA approved it in 1998 as a tabletop sweetener
and for use in products such as baked goods, nonalcoholic beverages,
chewing gum, frozen dairy desserts, fruit juices, and gelatins. Earlier
this year, FDA amended its regulation to allow sucralose as a
general-purpose sweetener for all foods.
Sucralose cannot be digested, so it adds no calories to food. Because
sucralose is so much sweeter than sugar, it is bulked up with maltodextrin,
a starchy powder, so it will measure more like sugar. It has good shelf
life and doesn't degrade when exposed to heat. Numerous studies have shown
that sucralose does not affect blood glucose levels, making it an option
for diabetics.
If Sucralose cannot be digested, I wonder if it can be utilized by yeast; I
strongly doubt it. If not, it would be an ideal sweetener for applidcations
like sweetening mead, wine, etc. where you don't want additional
fermentation and don't want to add Campden tablets or orther yeast killers.
I use it for coffee and corn flakes at breakfast; as a diabetic I can tell
you it is a dead ringer for sugar; far superior to Asperatame (Nutrasweet)
or Sacharine (Sweet 'n' Low) or Acesulfame Potassium (Succra) as a general
purpose sweetener. I wonder about the small amount of maltodextrine; since
maltodextrine is basically nonfermentable, if it has any effect at all, it
should barely add a slight bit of "mouthfeel" but the amounts to be used
are so slight that I personally doubt they would have any effect at all.
(One packet allegedly= 1 tsp sugar in sweetening power, but to my taste
buds you can halve that.) I think there is a research project here for
anyone so inclined; I am not. Don't mess with meads or antything that would
need sweetening. I offer this thought as a debate and departure point for
brave explorers. Good luck and let the collective know what you turn up!

Subject: Full vs. Partial Boils; Amount of water for Steeping
Neal Andreae started a thread about partial vs. full boils for extracts;
many responded with mostly the same opinions. Drew Avis agrees with the
points cited by most people, but disagrees with partial boils being the
source of "extract tang". As an extract/specialty grain brewer, I feel
compelled to offer my $0.02 worth:
For my own experience, I noticed an improvement when I went to full volume
boils. But before I can conclude that full vs. partial volume boils were
the reason for the improvement, I must note that this change occurred during
a period when I was learning many brewing techniques at a rapid rate, and
probably it occurred at the same time as some other unrelated improvements.
One change in particular that occurred at the same time and seems to also
make a big difference was the acquisition of a Cajun Cooker.
I can't disagree with Drew that old extract may be the more likely source of
extract tang. I can say that since I stopped doing partial boils, I have
not had any scorching or caramelization from the boil. I would agree with
Drew that good results can be achieved with partial boils by following the
guidelines he proposes, however, in my experience it is easier to mitigate
these problems using full boils.
The other question Neal raised (which has gotten less response) concerns the
amount of water used for steeping grains. Jeff Renner advised using 1-1.5
qts water per pound of grain. I would like to emphasize Jeff's advice.
Over the course of 2-3 batches which had an astringent taste, I believe I
discovered (with the help of the staff of Beer Necessities) that tannin
extraction from specialty grains was the problem. Neal, follow Jeff's
advice and use less water for steeping (I use 1.25 qt/lb in a separate pot)
and control the temperature carefully. I was amazed at the improvement in
brewing the same recipe with only this change.
And as an aside, the best developmental advice I ever got was to brew the
same recipe repeatedly in order to learn the impact of changes in brewing
techniques.

Subject: Teaching Pub
The original deal for putting a brewpub here at our store fell through. It
degenerated into an attempted land grab. Oh well, we move on!
I am contemplating the blending of a homebrew shop with a pub with a heavy
emphasis on learning about beer. I sort of envision a place where you could
go to drink good beer and learn a thing or two at the same time. For
example a dozen taps could be make from four worts using three different
yeasts. The idea would be that the customer could taste, say, a pale ale
made with Whitelabs British, English and Burton yeasts.
There is more to this than just the concept. It may help avoid a "change of
use" problem that can bring on demands for a lot of physical upgrades. I am
looking for suggestions to further the concept. To my knowlege, there is
nothing like this anywhere.

Subject: Homebrew Kit
Hi Everyone,
I bought a malt extract Christmas Ale kit from
www.morebeer.com and brewed it last weekend.
It is definitely nice to have the ingredients
pre-measure and the malt kits would be a nice gift
if you are wondering what to get for a would-be
homebrewer for the holidays.
No affiliation, just thought I'd give my 2 cents
worth.
