Subject: How much head, etc...
I am considerein building a wort chiller. Most likely I will build the
oter part from PVC pipe. rather than a hose, and coil tubing insde with
baffles so the flow does not channel. However, the outer shell aside,
I am quite worried about the inner tube. Therefore I would like to survey the
users of counterflow wort chillers with the following questions.
1) How much head? Ideally, I want to use no more than 2 feet, because
safety rule number one in my brewery is that a pot of boiling wort is
never ever moved.
2) How long? Diameter?
3) Hopback or not?
4) How long does it take?
5) How close does the outlet wort temperature get to the coolin inlet
temperature?
6) Can it perform aduquately with summer cold water temperatures?
Email or post.
(I wonder are editors of Zymurgy drunk the whole time or what? The number
of errors that they print in a rather thin magazine that comes out a mere 5
times a year amazes me. And it is so nice that they spend all that money on
postcards to tell me that I can buy CP latest book from them for $3 more than
the cover price because they like me. I am sure any bookshop around here
could get it for me in a couple of days and charge cover price?)

Subject: Mystery Marzen
Here's one for all the experts out there...
I made a partial-mash Marzen (a la Miller). I even used the recipe out of
his book which I am including in this post.
Grains: 1lb 2-row malt (I used Bavarian Pilsner), 2.5 lbs Munich Malt, 4 oz
40L crystal malt
Malt Extract: 3lbs light DME, 1lb amber DME
Bittering Hops: 6 AAUs Perle
Finishing Hops: None
Yeast: Wyeast Bavarian
Priming Sugar: 3/4 cup corn sugar
Gravities: 1.056 OG; 1.012 - 1.016 FG
Now to my question. When I took the OG it came in at 1.078?!?! How can this
be? I took into account temperature, and I even let it sit for 2 days so any
suspensions could settle out. I even went so far as to borrow a buddy's
hydrometer and got the same reading. What could cause this? What if I got
no conversion during my mash and only washed starch into my wort? How does
starch come into play with SG readings? What else could be in there causing
the reading to be so high? Is the only answer that the brewshop guy measured
my ingredients wrong?
I would greatly appreciate any insight into this mystery.
An unrelated question. I really want to go to all-grain, but I do not think
that I can convince my significant other that spending $100+ on a huge
brewpot is a 'wise' investment. I currently have a 5 gallon SS pot. My
question is does anyone know of an easy way to figure out how much extra
grain to add to a recipe in order to get the correct OG and still only end up
with about 4.5 gallons of wort? Does it make sense to try and do this?
Thanks,

Subject: Old Porter Brewed using Salvaged Yeast
In response to someone's not so recent interest in this story, I dug around
in my dusty archives and found a copy of an article which I clipped out of
the Int'l Herald Tribune (Nov. 29, 1991). The story is written by Steven
Prokesch of the New York Times Service.
It is about the successful efforts of a microbiologist, Dr. Keith Thomas,
to cultivate yeasts taken from two bottles of Porter recovered from a ship
that sank in the English Channel in 1825. He is now brewing Porter from
this yeast with a Porter recipe from the same era taken from the archives
of Whitbread. The significance of this beer is that it is an example of
what true Porter was like in the early 19th century and how, over time,
yeasts have changed through genetic mutation and brew recipes have changed
in response to consumer mutation.
The name of this brew is Flag Porter and Bottle Green. At the time of the
article, only about 4000 gallons per year were being produced. Flag Porter
and Bottle Green were being wholesaled by Vinceremos Wines Ltd. and most
of it was being sold through restaurants, specialty liquor stores, health
food shops, and pubs in the UK, though, according to the article, they were
hoping to start exporting to the U.S. in 1992.
This is a very interesting story for this forum, and I have not done it
justice with the scant details I have included here, but I don't know
whether it is legal to transcribe it without permission from the
publication or the author. Can anybody advise me on this?
I hope that this info has been useful for the person who was asking about
it.

Subject: NEW hop harrasment. Ants! /HBD 1492 KillKillKill
Yo Ho Ho.
Went out this morning to fondle my cones. Found a new source of concern.
A friend had a theory that his hops were devoid of spider mites due to
the fact that he had big black ants running up and down the vines protecting
them. The other day I was pleased to observe some med-sized black ants
winding their way around mine. I thought, "good...they'll keep the mites
down". This am I went out and found a large congregation of ants on a lower
region of the stem. I thought- aha! They must be feasting on some earwigs
or something like that.
After closer observation I discovered they were: Chewing on my vines!
Aaaaaaaaaaaaaaaaaaaaaaaaarghhh (as Charlie Brown would say)
There was a location where they had broken the outer skin and a mass of
them were greedily sucking the precious juices that SHOULD be pulsing upward
to my precious cones.
Well, needless to say, ants are no longer welcome on my vines!
(I generally don't care for them anyway)
I don't know if they help reduce mite populations or not. Perhaps it
depends on the type of ants. I just don't know or care.
SO: I grapped the hose and sprayer, and soaked em. Blasted the bastards!
(not enough to hurt the vine).
Question: Can Diazonon pellets applied to the ground around the base of
a plant be absorbed by the plant and tranlocated to my precious cones?
Or can I safely NUKE the bastards! I have no intention of applying the
toxin TO the plant, just the ground around the base.
It's been effective at encouraging ants to relocate elsewhere, I just don't
want to be making diazanon double bocks this fall!
As for other pests: I haven't seen much sign of the mites at the new house
(k-nock on head!), but I have had a fair bit of leaf chewing.
Exploration at night- via flashlight- has revealed the presence of earwigs
(on basil, and most all the other plants in the garden too!) on leaves.
They are known leaf niblers. Not a welcome sight, plus they look like
something out of a cheap mystery science sci-fi flick, so I don't like 'em!
Diazonon is also effective against those buggers.
I haven't seen signs of the Jap-Beetles, and my grapes don't show signs of
damage (if they truly are MORE attracted to them).
My Old hop plants have been DEVESTATED by spider mites. Murphy's Oil soap
is an organic approach, but I haven't heard much more than that mites don't
like water. So I guess an underleaf shower could be of help.

In other news: Here's my vote for the biggest load of crap I've seen
in a long time. (glad the administrator is back by now!)
HBD # 1492 Resend my buttox!
Who/What is OAKQM3 and the other culprits?
Has anyone publicly or privately SLAMMED these buggers yet!
Flame on Johny Torch! KEEP that CRAPOLA out of the digest!!!

Pressure Cookers: My 2c. I got a 6 qt number. Problem is it is so short I
am limited to very small vessels. It cost me ~$30. But in hindsight I
would gladly trade it and the $20 more for a taller one. I am limited to the
pint mason jars, and 250 ml ehrlenmeyer flasks. Kinda a hassle.
Go ahead and check the cheap outlets for a tall one. It'll be worth your while
As for sterilizing plates: You should get pre-sterilized plastic petri plates.
They are not- and will not be autoclavable. You could use UV light, or
other chemical methods. But also (to add to the difficulty) plexiglass
blocks UV. Some plastics will also to a certain degree.
SO: maybe you find unsterile ones cheap. Spend a bit more, get presterilized.
You can find glass petri plates. They are autoclavable. But are also more
of a hassle overall- IMHO. The best way to go: sterilize your wort/agar
and THEN pour into presterile plates.
As for slants- I go the other route. Make agar/wort, pour into tubes-
autoclave, and then cool on a slant. THe trick is to keep the caps loose
during autoclaving and cooling or the pressure changes will destroy the
tubes.
And as we are all so fond of saying YMMV.

Subject: Re: agar plate sterilization
Mark Gugle asks how to sterilize plastic culture dishes.
The simple answer is you don't. They should be largely bacteria free, if
not outright sterile before you unwrap them.
When we prepare agar plates for bacterial cultures in the lab we heat the
sterile agar until it is liquid and pour it immdiately into the dishes.
This is done in the presence of a lit bunsen burner which cretes a thermal
air current that theoretically keeps bacteria from falling into the dishes.
We cover the dishes and let them cool. When they have solidified we
invert them to keep condensation from falling onto the media and and store
them in the fridge until we need them.
When we are feeling really anal we use a culture hood. It is a box that
opens across the bottom and has plexi glass across the top to look through.
It has a bacteriocidal UV lamp in it to provide a sterile environment.
The lamp is switched off before use and need only be on 60-90 minutes
before and after each session.
Your mileage may vary.

Subject: Grape Nuts(tm) Pale Ale
Grape Nuts contain malted barley, wheat, and salt in unknown proportions.
Someone made a suggestion that they could be used in brewing so I tried
it, maily as a joke. However, the results were so good, close to an
excellent European pale lager, that I have decided to brew it regularly.
Eventually I intend to substitute regular malt and wheat, which are
cheaper.
INGREDIENTS:
4 gal. Las Vegas city water (high in calcium, sodium, magnesium,
chloride, and sulphate, about 750 ppm.) for mashing
3 gal. water from reverse osmosis filter system (about 60 ppm.
NaCl
2.0 lbs. Grape Nuts(tm) (1)
0.75 lbs. Vienna malt
5.05 lbs. 6-row Midwest malt
Total 7.8 lbs. grist
4 tsp. +/- commercial lemon juice (for acidifying)
3 cups Sierra Nevada(tm) Pale Ale yeast starter (2)
10.5 HBU compressed powdered Willamette hops (i.e. 2.1 oz. of 5%
AAU hops)
2.5 oz. leaf (plug) Czech Saaz hops
1 Tbs. (heaping) isinglas
1.5 cups Laaglander Extra Pale DME
METHOD:
Grind grains and Grape Nuts together and dump into mash tun with 4 gals.
mash water.
I used step-mash procedures: protein rest 45 min. at 122-124 dF; Opt.
added small amount of lemon juice (3); saccharification rest 47 min.
147-152 dF; dextrine rest 15 min. at 157-159 dF (4).
Don't try to sparge this; strain out the grains and trub with a fine mesh
stainless steel sieve and place in the hot (170 dF) sparge water for 20
minutes, then strain again. Combine the mash and sparge solutions and
proceed to boil.
After 20 min. boiling add 5.5 HBU Willamette hops. After 60 min. add 5.0
HBU Willamette hops (5). Boil for 1 hr. 20 min. total. Restore with water
(reverse osmosis) to 6 gals.
Cool to about 70 dF, aerate by splashing into a fermenting vat, pitch 3
cups yeast starter, and cover. My O.G. was 1.043 on 5.5 gals. Fermented
in a covered vat at 70-73 dF.
Rack to secondary carboy in 4 days and add five half-oz. Saaz plugs (2.5
dry weight) plus 0.75 cups Laaglander Extra Pale DME in 1 pint boiled
water (to stimulate the yeast to produce CO2).
The beer ceased working in 9 days; cleared with 1 heaping Tbs. isinglas,
hydrated and dissolved in 1 pint boiled water. After two more days,
bottled with 1.1 cup 50-50 dextrose and Laaglander Extra Pale DME
dissolved in about 1 pint boiled water for priming, plus 1 cup SNPA yeast
starter. Yield was 21 quarts.
This cleared in three days after bottling and was already comparable with
most better commercial beers. A slight chill haze can be remedied by
bottle-lagering at 35 dF for two weeks.
______________________________
NOTES:
(1) Use the genuine article, not a "house brand" which may contain oils
and other ingredients you do not want in your beer! Disclaimer: I have no
connection with whoever makes Grape Nuts(tm) and don't even eat the stuff
very often.
(2) I used Sierra Nevada(tm) Pale Ale yeast cultivated from a bottle to
make a starter; Wyeast 1056, that I have used and is an excellent yeast,
is not the same at all, although some people continue to propagate the
erroneous statement that it is.
(3) If the pH of the mash is a little high at this stage, add a tsp. or
two of lemon juice to lower it.
(4) The starch test was already negative at the end of the
saccharification rest so I doubt if there was much starch left to convert
into dextrine. Therefore, I would reduce the protein and saccharification
rests by 30% and double the dextrine rest to add body. Head retention was
good.
(5) I would reduce the bittering hops by about 20%, i.e. from 10.5 to
about 8.0. This is purely my personal preference. Even so there was no
lingering bitter taste, but a clean, dry finish.

Subject: not priming/hop poles w/ pulleys
Howdy, y'all,
In HBD 1494, Chris Stickland wants to know about bottling beer early instead
of priming. This is a possibility, & is actually done by some commercial
brewers. There is a trick to it, however. You have to know exactly what your
final gravity will be, then figure backwards to what gravity you need to bottle
at to get the right carbonation. It's easy if you're a commercial brewer,
brewing the same thing over & over, & you can trust the numbers. However,
almost no (I've learned to never say "all" or "none", there's always the
exception) homebrewers can enjoy the luxury of having the same exact beer do
the same exact thing. So, we prime. If you have a favorite recipe, however,
that you've done over & over, & you get the same gravity readings consistently,
try it. Just remember, though, that a small mistake could lead to those
nasty little glass grenades.
Thanks to The Coyote for posting his pulleyed hop pole instructions. I just
bought a house with the perfect spot for hop vines, & I was trying to remember
just this weekend who posted the idea of the pulleys & whether it worked. But
first I have to do some re-wiring for the ol' brewing fridge...
BTW, rumor has it that the psuedo-lambic that won the AHA nationals was an
extract. Any truth to that?

Subject: Christmas Brew Formula's
Greetings. I'm a newbie, so be gentle.
I'm looking for any and all formulas for a Christmas Brew. (I use the
word 'formula' because I was raised in a Bakery and we never had
'recipes'. Go figure!)
E-mail would be great, no sense taking up bandwith, etc.
Also, I live in St. Louis and I too do not by A-B products. Especially at
Busch Stadium. I can't see paying $3.50 for a can of beer under any
circumstances. But also for the reason that I have somewhat of a loyalty
to Miller as a commercial product. I went to school in Milwaukee and Miller
has a great and informative brewery tour. I do like their line of Special
Reserve products better than their regular products but anything beats A-B
products. Why is A-B the best? IMHO its all advertising.
Luckily in St. Louis we have an alternative. The St. Louis Brewery. Dave
Miller is the Brewmaster and they have some great beers. His Cask Ale is
probably the best I've ever tasted.
Anyway...send those Christmas Brew formulas along. Thanks!

Subject: Boilover Made Easy...
Splash!!! Sizzle!!! Phewww!!! Those telltale signs that the batch has
decided to leave the nest early...These are some things that come to mind:
(Not necessarily in order of occurrence or level of frustration...)
1. Telephone rings and I get into some half hour conversation with someone
I haven't talked to in a while and forgot about the boil...
2. Was doing something related to the next step (sterilizing fermenters
weighing hops, etc.) and forgot about the boil...
3. I'm cleaning up where the cat puked after he ate some of the hops
that I was weighing out for the finish in #2 above and forgot about
the boil...
4. Decotions. Decotions get me all the time. I've outlawed all
decotions in my house with the exception of weizzen batches. However,
when I do do one, its upstairs, away from the main operations in the
basement...
5. The cup runneth over. I've got a SS Half barrel for a fermentor,
and if I push it, it will hold 15.5 gallons, with an inch to spare.
But don't look at it wrong, rock it, or otherwise say the word "worry"!
6. Wheat again. Attack of the grey crud from Hell!!!
7. Turned up the heat when I meant to turn it down. My jet engine
keg melter has a valve that closes by turning counterclockwise
rather clockwise (like the rest of the civilized world...). All it takes
is a quick 150K BTU blast to push that 15.5 gallons from #5 the last inch.
8. Disbelief. A watched keg never boils(over). (Bullsh#t).
9. Was doing something unrelated to brewing, like breaking 1/4-20 taps
off in the pig roaster mounts (arggg!!) I was working on.
10. DIDN'T RELAX, DIDN'T HAVE A HOMEBREW, WORRIED...

Ah yes, I would be wary of using a used whiskey barrel for making beer but
a used whiskey barrel provides an excellent mechanism for maiking a port wine,
especially the first year. Port wine generally uses muscat grape which is white
and some red grape like Zinfandel mto provide a rose color. The whiskey from
the barrel forifies the wine perfectly.

Subject: Waste Water Management
Tom Wurtz remarked about wasting water while using his wort chiller. I
live in California where we have had several dry years and I found that
if I connect my garden hose to the outflowing end of the chiller, I can
connect the other end to a lawn sprinkler and water the lawn a little
while I chill my wort. In the summer my water is about 65 to 70F from
the kitchen tap. By running the garden hose into the kitchen (my wife
typically needs to be gone to do this without too much flack) I can
water my lawn for about 15 to 20 minutes. At least it's not going down
the drain and I can have some homebrew while I cut my lawn!

You can use any pressure cooker to sterilize things. I really dont like the
cheap gasket ones though. I really like the All American brand. They are
in a totally different league. They have no gaskets, but a series of giant
wing nut like things, you batten down the hatch and it does not leak any.
It has a guage, and a very nice blow off valve, it will gently hiss away any
extra pressure (more if you have the heat way overcranked) so it wont cause
your agar or starter liquid to boil out. I have 2 of them, I got the small
standard one over 10 years ago and it shows no signs of use except when I have
loaned it to friends. I have a big one now that you can put a gallon (cider)
jug of starter liquid in (Not quite with the glass airlock on, I put the
airlock and stopper wrapped in foil next to the glass and keep foil over the
jug lid).
These are expensive when new, but they are available at used restaurant supply
places and I would suggest checking there. At least take a look at one to get
an idea of what the different grades are like before you get a cheapo one.

Subject: Re: unusual fermentation (& ``funny tasting'' extract)
I'm a newbie homebrewer currently on my third batch. I've used Edme dry
yeast on both the first and third batches, and noticed the same
behavoir (fermentation goes strong for ~1day then just about stops). I
don't have a hydrometer, so I don't know what the gravities are/were.
For the first batch, I bottled it after two weeks. It turned out mildly
carbonated, but the yeast aparently ``woke up'' after two months. On
the final bottles, the dimple in the cap popped out, and the beer was
way over carbonated. It didn't gush on opening, but it was like pouring
foam.
Now, I have a question about my third batch, currently in the fermenter.
When I tasted the liquid extract I used, it didn't seem to taste right.
It didn't have the `normal' heavy malt sweetness of the previous
extracts I've used. It had sort of a tang, almost a slight orange
flavor to it. Is this a bad sign? (I got a 7lb bucket of some cheap
light bulk extract to try it out. Is this a case of getting what you
pay for?)

Subject: Counter Pressure Fillers
For those of us who don't have a nice counter-pressure filler (CPF)
setup like Dion's, maybe he and others could answer a few questions.
I recently bought a CPF and ran into a couple of problems.
1. What pressure setting should I use for filling? Dion (#1493)
mentioned 30 psi, I can't imagine filling at that pressure
with my setup. What effect does raising/lowering the pressure
have?
2. I ran into a severe foaming problem. How can I eliminate
or reduce foaming?
3. If I want say 2.0 volumes of CO2 in my bottled product,
how many volumes of CO2 should be in the bright beer to
compensate for CO2 losses? What other factors are involved?
4. What would be the top range of CO2 volumes that are feasible
to achieve with a CPF?
5. What is the shelf life of an unfiltered CPF bottle of
brew vs. a bottle-conditioned one?
If Dion or anyone else responds, I would be happy to repost the summarized
results. Thanks.

Subject: Dry hops/pressure cookers/hydro correction/Anchor Porter?
Dear Friends, for once I am not just asking questions! Several comments
on some articles in HBD 1495, and then one question. Jack Dickerson asks
about better ways to sink his dry-hops. In my view, it doesn't make a
particle of difference whether the hops are floating on the surface or
sitting on the bottom, especially when they are in a hop bag. The
volatile aromatics you desire from dry-hopping dissolve into the beer via
diffusion, and this process is totally independent of whether the hop/beer
interface is above or below the hops. That is, the "random walk" nature
of the diffusion process is irrespective of gravitational fields. As long
as the hops stay in the beer for long enough, say a week or more, there is
ample opportunity for the dry hops to do their thing. So Jack, just toss
'em in any old way you want.
John DeCarlo asks about what type of pressure cooker to buy for yeast
culturing use. Never in my wildest dreams thought I'd be offering advice
to John <grin> but I'd say that if you are going to be plating out strains
that are probably not pure, so that you need to worry about extraneous
critters, then p/c's are probably a good idea. If you are working only
with yeast from *pure* sources, like Wyeast packs or slants, IMHO a p/c is
not necessary, and 20 mins of steaming in your covered brewkettle is
plenty of sterilization. In either case, in my experience (admittedly not
that large, my yeast herd is just 5 strains so far) buggered-up yeast
colonies are quite easy to pick out with the naked eye, so I (so far) have
not bothered with a pressure cooker.
Tim Ihde asks about how most folks take samples during the sparge/brew
process, and about corrections for temperatures greater than 120F. What I
do is take a sample once everything is in the brewpot, on the way to
boiling temperature (whether it is an extract- or mash-based brew) and
then measure the gravity (for partial-mash brews, I also measure before
adding the extract syrup). I cool only if I need to get down to the T
range where my hydrometer corrections apply. Tim says he had to
extrapolate up to higher T from the data he had. Here is the correction
table from Dave Line's Big Book of Brewing, both for general use and to
solicit people's opinions on whether this has changed much in the years
since BBB's publication. Does this still hold up, and if not, why not?
The Line method is to use "hydrometer units", i.e. a gravity of 1.045 is
45 units. Then the factors given below are used to multiply the hydro
units. Example: a wort at 120F measures 1.038. This is 38 hydro units;
the factor is 1.52; 1.52*38 = 57.8 (call it 58) so the actual gravity is
1.058. BTW this is all assuming a hydrometer calibrated to read water
with a gravity of 1.000 at 60F, so there is no correction at 60F.
T, F Corr'n factor T, F Corr'n factor
50 0.98 120 1.52
70 1.02 130 1.70
80 1.05 140 1.92
90 1.11 150 2.15
100 1.22 160 2.42
110 1.36 170 2.75
It's clear from this that the correction is strongly non-linear, so
extrapolating above 120F if your data don't go any higher needs to be done
with care. A simple test (so simple I have never done it!) would be to
take a sample at the hot end of the range, do the correction, then cool it
to the mid- and low-end of the range and see if those corrections result
in the same gravity.
OK, finally my question: anyone know if Anchor uses the same yeast for
their Porter as they do for the illustrious Steam beer? I'm going to make
a Porter using Wyeast 2112 (it is perfect for the 15-18C temps in my
apartment these days) and would appreciate any comments on what I might
expect from this.
Cheers, Dave in Sydney

Just want to point out that having Brewpubs and supply shops does not
ensure that home brewing is legal. Utah is a case in point. We have
5 brewpubs and micros, with three more on the way, and many supply
shops; however, home brewing is as illegal as ever. In fact, I had
quite a scare when two cops parked across the street while I was
heating my strike water outside the garage. They didn't seem to pay
me any attention. I guess that they were looking for something else,
but boy way I nervous. I had 10+ gallons of brew in my fridge with
the taps in nearly plain view.
Anyhow, shops and brewpubs do not equal legal homebrewing.

Subject: Gas Cylinders
In HBD 1495 Kelly Jones <k-jones at ee.utah.edu> asks about gas
cylinders.
They are regulated by the DOT (Federal Dept. of Transportation)
and are covered by ANSI standards. The American National Standards
Institure has set forth the standard that cylinder contents will
be marked by means of the chemical or trade name of the gas marked
on the cylinder not by a color code.
I don't think many welding supply houses will but CO2 into non
CO2 cylinders because of the DOT regulations and the liability
they may incure in a non standard cylinder. You may find a
fire protection or service company that will, but I think even
that is unlikely.
By the way that is a good place to purchase smaller size cylinders
in the 5 to 10 pound size. I use a 50 pound cylinder purchased
from my welding supply house for about $ 90.00. It lasts for ever,
about a year, and I use it for lots of things. One big drawback
is that it weighs in at about 200 pounds, is more than 5 feet tall
and damn hard to take to a party.

Has anybody heard of a hand cleaner called Mixxocydin (TM)? It is intended for
the medical and scientific communities, and has the active ingredient called
QUATERNIUM-12.
My thoughts/questions were: 1) Would this be effective against Lactobacillus?
2) Could Quaernium-12 (which I was told is made from grapefruit seed) be a

Subject: Polyclar
Greetings to all in homebrew-land! I have a question regarding the
use of polyclar as a clarifying agent. A few weeks ago I brewed
an all-grain golden ale, and dry-hopped it for about a week with
one ounce of Cascade whole leaf hops. It still looked a little
cloudy, so I decided to use a bit of polyclar to clear it up a bit.
In the past, all I did was to sprinkle a couple of tablespoons
of polyclar powder on top of the fermented beer in the secondary.
This worked well. But alas, I recently purchased Dave Miller's book,
which said to hydrate the polyclar in about a cup of beer from
the secondary. So, I did this, and had a helluva time getting the
polyclar into solution. Anyway, I finally got it into solution
and poured it into the secondary. Three days later, it still was not
clear. I decided to bottle it anyway.
Almost two weeks later, the beer is *very* cloudy, almost
white in the bottle. It is carbonated perfectly, and even tastes
great. I pride myself in that I have never had an infection,
and I am nearly certain that this beer is not infected. What
did I do wrong? A bad batch of polyclar? Will this eventually
settle out? Should I relax, don't worry, and serve cloudy
homebrew to my friends? Any thoughts, private or otherwise, would
be appreciated.
TIA

Subject: Water Bath Cooling
Someone mentioned keeping a carboy in a water bath at 80 degrees and wanted
it to be cooler. I don't have a water bath, (which would be easier), but
I just wrap a wet towel around my carboy. I wet it twice a day, and it keeps
the carboy at 65-68 F, though my house is cooled at 78-80 F. The evaporation
cooling effect works well. I was talking to my dad about this and he said when
he was in the military, they'd take canvas bags full of water and hang them
up when in the desert. Though it was near 100 outside, the water in the bags
was cool and refreshing. Same effect of the evaporation cooling.

I've one question, however--rich writes:

I dunno about the rest of you, but i've _never_ been able to get a good

Subject: Using Green Beer to Prime
You need to save enough beer to raise the SG of your beer by about
.004. The (simplified, but fine for this task) equation for the
gravity of mixed worts is:
extract(mixed) = [vol(beer)*extract(beer) + vol(wort)*extract(wort)]
---------------------------------------------------
[vol(beer) + vol(wort)]
Where extract = 1000*(SG - 1.000), for simplicity. Rearranging this
to isolate vol(wort) gives
V(w) = [(E(m) - E(b)) * V(b)] / (E(w) - E(m))
Substuting E(m) = E(b) + 4, gives
V(w) = 4*V(b) / (E(w) - E(b) - 4)
Thus, if we had a 1.050 wort, 5 gallons of beer with a final gravity
of 1.008, we would need to save
V(w) = 4 * 5 / (50 - 8 - 4) = 20 / 38 = .53 gallons
= 2.1 quarts
of wort. Of course, you've got to estimate your FG in order to save
wort before fermentation.
Another, perhaps more useful calculation is this: If you've got a
certain volume of wort, and you want to save some, how much should you
save. In that case V(beer) = V(initial-wort) - V(saved-wort), and the
equation becomes:
E(m) = [(V(i)-V(w))*E(b) + V(w)*E(w)] / V(i)
or
V(w) = [(E(m)-E(b))*V(i)] / (E(w)-E(b))
Substituting E(m)-E(b) = 4, we get
V(w) = 4 * V(i) / (E(w) - E(b))
The example case then gives
V(w) = 4 * 5 / (50 - 8) = .48 gallons = 1.9 quarts
Hope this helps.

Subject: Bacteria in tap water
I first became aware of this problem a few years ago. Our water
smelled very strongly of chlorine, so I called the water treatment
plant. I had a chat with one of the chemists. He explained that they
used chloramine to sanitize the water, and that it is odorless.
However, in the 3-4 days it takes the water to get from the plant to
my house (I'm at the edge of a "pressure district"), nitrifying (?)
bacteria *in the pipes* convert the chloramine to free chlorine (and
something else).
The water analysis I ordered at the same time listed something like 99
"cfu" (colony-forming units) of bacteria (per some unit I can't now
recall, probably milliliter). Clearly this water is not sterile.
While I'll take their word that it's safe to drink, I'm not going to
take a chance on what might grow in my beer. I don't even rinse with
tap water, let alone use it unboiled in my beer.

Steven Cook says he is worried that the straining procedure
can infect his batch. I suggest, No More Straining!
Steve, tie your hops and a half dozen marbles loosely in a
piece of sanitized cheesecloth during the boil. (Actually,
the boil will sanitize it but I boil the cheesecloth
separately first, just in case.)The marbles will effectively
keep the hops bag from floating to the top of the wort but
won't allow it to sink all the way to the bottom. When you
are finished boiling the hops to the proper bitterness level
to suit your tastes, just remove the whole bag from the
batch. No more scum! Try it, it really works!
