Subject: Help, Low Carbonation!
Well now its happened to me, a batch with very low carbonation.
I brewed two 2-1/2 gallon batches of Barley Wine based on Rob Molines
recipe and the Big Brew event. Both batches were nearly identical
extract recipes using steeped 40L crystal malt, and M&F light extract
and an OG of about 1.098 and an FG of 1.021 for a whopping 10% abv.
Plenty of yeast was pitched and based on the attenuation it seems that I
certainly pitched enough. The differences between the batches is that
one was hopped to about 55-60 IBUs (per Rager) and used Wyeast 1728
Scottish Ale yeast, the other was hopped to 75-80 IBUs (per Rager) and
used Nottingham dry yeast. I figured I'd just be patient when my early
samples showed almost no pop or carbonation but now its been 6 wks. and
the carbonation levels haven't changed. The batch with Nottingham seems
to have a slight fizz sound when I open the bottle so I think its
slightly more carbonated than the Wyeast 1728 batch. Both sat in the
fermenters for 3 weeks so I don't think I waited too long to bottle. I
always weigh my sugar as I found that using volume like 3/4 cup was a
mere 3 oz in some cases. Settling of priming sugar was too inconsistent
for my tastes so I weigh the amounts and use batch priming with a slight
stirring in the bottling bucket to get even carbonation in the bottles.
So, should I put a pinch of yeast (Nottingham) in each bottle and recap?
What has worked for you other HBDers especially with such a high alcohol
beer?

I am not sure of what your getting at here. If I wanted to know exactly
what was left in a beer, I would do my own lab work or send it off to
Siebels
or similar. Not may homebrewers can afford to send it out or do it
themselves.
Granted I never used Clinitest, and it would be a nice extra data point
to
stack next to the fast ferment data I had.
Fast ferments are typically not used for "bug detection" altho you can
plate
from it along side of the tank. One key to insuring a good test is
"clean"
sampling. For most homebrewers this is not possible, for most
commercial
micros this is not possible (ever take apart a zwickle - they suck
period.)
There are other sampling points and tests to determine stability. If
you have
visible problems at this point - your screwed anyway. Time to distill
or dump it.
As for the measurments varying batch to batch, it could -granted. But
every
time you perform the fast ferments the parameters "should" be the same.
(again this is for the brewsheet of the particular beer being produced)
All of these: time drawn, cell count at the draw, cell count at the
"end", temp
of the fast ferment, agitation speed, and probably a dozen more
parameters
need to be monitored. One of the key points in doing this is to find out
with the yeast you are using "how low can it go". In most cases the
tank
will not get this low - but you have the bottom. Provided you have a
nice set
of hydrometers/sacharometers - not the $5 per - more like the $80 per
and
a set of three. I was fairly sloppy with some of the parameters, but
did
this method on over 300 batches, and there was not alot of variances
typically.
On maybe 5-10% (dont have the brewsheets handy) there was variance, but
I did not need the fast ferment to show that. Primed CO2 levels where
very
consistent over a wide range of products. But the key to this is "how
low
can it go".
1800's - sure it is. time consuming - it depends, for a home brewer to
"waste" several hundred mL, yeah I would go Clinitest too. But it is
the only
simple, easy to do , cheap method that can determine what the pitched
yeast will do to the wort. These measures come into effect with the
priming
calculations (if you do that pre 1800's thing). Not knock Clinitest
again, I wish
I had had it...

I don't think this is just a marketing ploy. I believe that the "contains
sulfites" label serves as a warning to the small portion of the population
that is sensitive to the presence of sulfites in foods, beverages, and
medicines. There is indeed a vast literature on this topic in scientific
journals. I bumped into this by accident after challenging a co-worker who
was complaining that MSG in Chinese food gave her a headache. I'd heard
lots of stories about this and always dismissed it as an old wives tale.
She challanged me to put my money where my mouth was so I did some
checking and damn if it wasn't true! There are a whole class of verified
sensitivities to food additives, notably MSG, sulfites, and nitrites with
catchy names like "Chinese Resteraunt Syndrome" and my favorite "Hot-dog
Headache." (the names are uncharacteristicly humorous coming from
clinicians but the publications are in respected journals such as
Lancet...). This whole class of disorders falls under the name "Resteraunt
Syndromes" and also includes sensitivities to naturally occuring chemicals
such as amines found in cheese, wine, and chocolate. But, I'm straying
from the topic at hand, namely sulfites.
Apparently, sulfite hypersensitivity is usually, but not exclusively,
found in chronic asthmatics. Studies vary as to the proportion of
asthmatics that are sensitive but the consensus seems to be around 5% -
10%.
There's a good review by Lester in the Journal of American College of
Nutrition which I'll quote from:
"As food additives, sulfiting agents were first used in 1664 and approved
in the United States as long ago as the 1800s... They are currently used
for a variety of preservative properties, including controlling microbial
growth, preventing browning and spoilage, and bleaching some foods. It is
estimated that up to 500,000 (<.05% of the population) sulfite-sensitive
individuals live in the United States. Sulfite sensitivity occurs most
often in asthmatic adults--predominantly women... reactions vary widely,
ranging from no reaction to severe. The majority of reactions are mild.
These manifestations may include dermatologic, respiratory, or
gastrointestinal signs and symptoms... bronchoconstriction is the most
common sensitivity response in asthmatics. The precise mechanism of
sensitivity response has not been completely elucidated..."
So, it appears that in some small fraction of the population there can be
a problem with sulfites. Does look like the rest of us needn't wory
though. But, if you have friends who have asthma you might want to keep an
eye on 'em while they're trying out your latest batch of wine.

Subject: more sulfites...
Hi All.
Another brief note on sulfites - yes they are in fact produced by yeast
during fermentation. In fact, there were a couple of papers published
recently in which attempts were made to increase the amount of sulfites
produced by the yeast. This was done by inactivating a yeast gene called
MET10 which codes for a subunit of the enzyme sulfite reductase.
Inactivation led to an increase in sulfite accumulation and it was claimed
that beer made with such yeast showed increased flavor stability...

The other factor that the Big Boys have going for them is the significant
economies of scale in terms of the actual cost of capital equipment. A
lagering tank for a megabrewer that has 50 times the capacity of a
microbrewer's aging tank doesn't cost 50 times as much, it's more like 7 to
10 times as much (if those equipment scaling cost factors that I looked up
in my design book are really valid). Therefore, on a cost per barrel
basis, the megabrewer's tank is only 14 to 20% of the microbrewer's tank.
Apply this to most of the other capital equipment. It's cheaper to build a
megabrewery than a micro when you're looking at it from a $ per barrel of
production basis.

Subject: Canning/Propane
Bill Coleman in HBD 2787 asks about a couple of issues:
Canning lids: of course the manufacturer says to use the lids once -
they sell more of them that way! You can use them over and over, but,
eventually they may not make a good seal any more. Check out a new
one versus one used a few times - see that the rubber has been
compressed on the used ones. I use mine over and over until they look
just too beat, or if they get a spot of rust on the inner lid (like
from stupidly using a bottle opener on it!) Think of the lids as
Grolsch Bottle gaskets - they last quite a while, but eventually they
do need to be replaced.
Propane: I have found that I can get about 3 or 4 10 gallon batches
out of a standard 20# propane tank. If you are going to use the small
ones (1 or 2#) it better only be as a spare since my numbers would
indicat that you'd probably need about 2-3# for even a 5 gallon batch.
Currently I only have about 4 spare 20# on hand - not counting the
two on the grills . . . but I think when my neighbor moves, he's going
to leave behind another couple . . . I don't find a problem keeping
them around (just keep them out of my wife's sight!) . . . then again
Ontario is a bit different than Brooklyn ;-> Also, I can usually get
them filled for about $7-8 around here.

My suggestion is that you use a very small gas line. What I will do
(someday) with my setup, but haven't done yet, is to drill a small hole
and use tiny 1/8 tubing, or even smaller metal tubing, then place a pin
lock gas-in connector fitting on the outside cabinet on a bracket of
some kind. This will be connected through the tiny tubing into the
fridge inside where I will connect a pin lock connector to use for my
kegs in the fridge.
The small tubing allows as much pressure, just a slower flow rate. We
are not concerned with flow rate here, so you can use very small tubing
and only need a small hole.
Whadda ya think??

Subject: Wheat, White, Wit, What?
I'm not a very classy type of guy, just a little old hillbilly up
here in Vermont. I'm not even sure which type of knife it is
socially acceptable to eat my peas with.
Anyway, this whole business of beers made from wheat has me very
confused (actually many things have me confused, but this will do for
the moment).
While driving through New Hampshire on my way back from the seacoast
I stopped at a small grocery store for some beer to drink on the long
ride home (my wife was driving). It was the end of the weekend,
funds were low, and I saw some 'Blue Moon Belgium White'. I don't
want to bring up that old thread again, but having lived through the
arguments, I was curious just what it tasted like (bear in mind that
I'm from Vermont and to this day have never seen a Cellis or
Hoergarden). What the heck for $4.99 the price seemed reasonable.
For better or worse, I liked it. This is the first 'wheat beer' I
can truly say that about. Sam Adams, Pete's, Long Trail,
Breckenridge,...I just don't like that 'wheat' character. And I have
NEVER noticed any bananas or cloves in any of them, although I've
looked for those flavors.
After all this, my question is - "was I supposed to shake the yeast
back into suspension, or decant off the yeast in the bottom of the
bottle?" This Blue Moon is the first wheat beer (white? wit?) I've
had with a sediment in the bottle, and I know that some wheats are
supposed to have the yeast in suspension when you drink it.

squish into place, and is less reliable after one use. It doesn't mean
they all WON'T hold, it just increases your risk of lid failure.

I doubt that anyone has tried it. I didn't know until recently that it
was extracted and used by the food manufacturing industry. My best advice
is to give it a shot and report back on how it works, if you feel like
trying it.
It may be that the moss itself provides sites for protein coagulation, but
that's rank speculation.
Carageenan is sold as a gelling agent, and is expected to remain in the
food. I assume it's extracted so you don't have to add visible/tangible
moss, and so you can measure it very precisely and repeatably. Neither
issue really matters for us. So, I'd use whichever costs less and does
the job.

Subject: Problems w/ carbonation in bottled beer
I will present a problem that a new brewer friend of mine presented. I
couldn't give him a good answer so I have decided to present the
collective in hopes that combined experiences will yield an answer.
My fiends problem: Some of his homebrews have carbonation and some don't
after 2+ weeks in bottles.
He brewed a wheat beer w/ dry yeast (of unknown type) and bottled w/ 3/4
cup bottling sugar after 1 week in the primary and 2 weeks in the
secondary fermenter. He created a sugar solution and racked his
fermented beer on top of it, mixed it up and bottled. He purchased
bottles from a homebrew store and ran them through the dishwasher w/ no
soap before bottling. The beer was fermented and stored in his basement
which has a temperature in the low to mid 70's (here in the Washington,
DC area)
The only thing I can think of is that there wasn't enough yeast in
solution (unlikely since some if his beers carbonated) or that he didn't
mix the sugar solution well enough. I have discounted detergent residue
in some bottles b/c he ran them through the dishwasher with no detergent.
He did bottle while the bottles were still hot, but I don't think the
heat of the bottles could have killed the yeast.
Anyone have any ideas?

You can re-use the dome lids if you want, it is just not recommended.
After a few uses the gummy material that forms a seal with the lip of the
canning jar will deform and not seal properly. Also the lid itself becomes
bent with repeated use (prying it off with a bottle opener, for instance).
Sterility is not the question, a proper seal is. As long as it still seals, you
should be o.k. But extra lids are cheap, why take chances? The
threaded ring part is re-useable any number of time. I usually use mine
for years until they become so rusty from repeated use that they will not
tighten properly.

Sorry if I identified the wrong poster. I snipped the material directly from
HBD 2781 (July 29) and it appeared in my post exactly as in appeared in
HBD 2781 (heading and all).
Anyway, I am not trying to *condemn* anyone. And my advice is based
on experience also. All I am suggesting is that if after some threshold,
over-pitching yeast can cause stability and flavor problems in finished
beer, pitching the equivalent of a 5 liter (1.32 gallon) starter in a 5 gallon
batch of moderate gravity ale may be approaching this threshold. This
hypothesis is based solely on information that I read in the HBD last
week. And, as I indicated in my previous post, I do not necessarily
believe or disbelieve it. I am just trying to figure out *when is
over-pitching, over-pitching*. Either over-pitching occurs or it does not.
You cannot have it both ways. What if I were to suggest pitching 3 or 4
dried yeast packs? Based on your post that a typical dried yeast
package is 50 times the yeast of a Wyeast smak pak, this would be the
equivalent of pitching a starter volume of 7.5 L to 10.0 L (or about 2 to
2.6 gallons). Am I over-pitching yet? I do not know and I am just trying to
figure it out. Somehow I do not think that pitching even 4 dried yeast
packages will cause harm to the beer. Therefore, either the information
that you supplied that a typical dried yeast package is 50 times the yeast
of a Wyeast smak pak (which I tend to agree with) is false, or
over-pitching is a myth. Maybe under-pitching is too!

It's not that Jack is a money grubber. Not at all. I believe him when he
says he doesn't need the money generated by selling brew stuff.
Unfortunately, Jack's zeal and pride in what he does is both to his
credit, and his undoing. He doesn't bash competing products because he
wants the sale: he does so because he is convinced that his is better. (In
many regards, so am I.). Jack, though he "sells" product, remains a

Dear Collective,
Robert Johnson wanted some suggestions as to where to drill a
refrigerator for a CO2 line. I just got rid of a veeeeery (sorry about the
spelling AlK ;^) ) old Frigidaire that had the freezer inside the refrigeration
compartment. It was drilled on the right side about 6 inches from the
bottom and 6 inches from the back. I replaced it with a newer Kenmore
which I drilled on the left about 6 inches from the bottom and three inces
from the back.
When I say I drilled the hole, I really used a hole saw on a drill to
accomplish it. I drilled from the inside, cut through the inside layer and
then stopped. The side of the refrigerator had fiberglass insulation, so I
was able to kind of push the insulation aside (watch out for the sharp
edges!) and peer into the refrigerator wall to see if there were any
refrigeration lines in the way. As it happened, it was clear, so I finished
it up.
As usual, YMMV.

Subject: attenuation/yeast starters
There has been discussion lately about attenuation from different yeasts and I
thought I would add what I have noticed. I have not compared ale to lager
yeasts but I have split a batch and pitched different ale yeasts. One was
Wyeast 1968 and the other another Wyeast British ale yeast whose number I
don't recall. The 1968 batched finished and dropped clear in a week while
the other batch took two or three weeks to clear. They both ended within
one point of each other in FG, though. Also, I could not reliably tell the
difference in the beers when comparison tasting.
As to starter size, I have had higher FG with smaller starters and/or poorly
aerated worts but can't say what the taste differences were, except that the
higher FG made a sweeter beer, to my taste.

through 50C on the way to 60C with no rest. That's what I do with good
results. Of course, I can ramp at about 1 degree C/minute with my bottom
fired RIMS. (Gee, I hope your text reader can handle these abbreviations
and acronyms). Also, I'm beginning to think that a 70C (158F) rest,
while historically correct, in my system results in a less attenuated, less
crisp beer than I'd like. My last batch, presently lagering, I rested at
153F, then 158F (George Fix has reported improved foam stand with 15 min.
at this temp).
One of the nicest, crispest CAPs I've had was single temp infusion mashed
(probably with mashout) at 152F. So we may be overbrewing, so to speak.
On the other hand, I like fussing. But don't think that you have to step
mash, because it ain't so.
>Yeast:

Back in pre-Fritz Maytag times, Anchor Brewery used to get yeast from
whichever local lager brewery had yeast when it was time to brew. I
suspect that later Fritz chose a yeast that he was happiest with, and that
it was probably a local lager yeast. But we'll probably never know; they
play their cards close to the vest. 2112 is reputed to be that yeast, and
should probably work. I have had friends ferment CAPs with it at lager
temps with good results. 2007 is reputedly Anheuser/Busch and very
neutral. That's OK, but maybe you'll want a little more character. I do.
A friend got diacetyl in a CAP using it. I don't know his fermentation
temperature regime. If you use a yeast that is prone to throw diacetyl, be
sure to give a 60F rest at the end of the primary, when there is still a
little fermentation going on.
>Hop to 30 IBU
>FWH Saaz or Styrian Goldings
>Bitter with Cluster
>Flavor with Styrian Goldings
>Saaz or EKG ?? knock out
All are good except the EKG. Historically and stylistically inappropriate.
It seems strange that Styrian Goldings, which is Fuggles grown in
Yugoslavia, should be appropriate, but it was used historically, and it
doesn't taste English, at least to me. I think it would be better to not
use it for FWH, however, but go with Saaz, Hallertauer or a combination of
both. I've not found historical evidence for FWH in the US, but there is
evidence of it in Germany 100 years ago, so I have to think that some
German brewers who emmigrated to America brought the practice with them.
Good luck and let us know how it turns out. Oh, and congratulations on the
impending arrival of the new brewer. Brew now while you can, because the
next 18 years are a roller coaster ride with no getting off until the end
of the ride. Right now you're on that slow clank, clank, clank up the up
the first hill. The bar is down across your lap and you're locked in, but
the ride hasn't really started, yet. Then you reach the top and wow! Your
world is changed forever. But I wouldn't have traded my ride for anything.

Subject: History of stout
Brewers,
Towards the end of June, I asked the collective for some information
regarding the history of stout. My intent was to sum it up for a club
meeting. Thanks to those of you that responded. For anyone that is
interested, I've posted my write-up on our club's web page at
http://hbd.org/starcity/style/199807a-history.html
While I certainly welcome feedback and constructive criticism, I have
no real intention of updating the contents. It is a snapshot of my
presentation in July. If you have some interesting comments, I may add
them at the bottom. Let me know if you would like credit for your

I've asked so many questions, it is nice to give something back,
however minor!
Cheers,

Subject: re: propane tanks
In #2787 Bill inquired about the duration of propane tanks.
I have 2 different propane cookers. One is the Cache Cooker SH-140L,
the other is the King Kooker H/S PK 90.
The King Kooker is the "jet burner" type and I have found that I can do
about 10 70 minute boils before I start getting too low on propane.
The Cache Cooker is a ring type burner with 24 flame points. I have
done 5 70 minute boils, and heated my sparge and strike water for my
first all grain batch and I still have over 1/2 a tank left.
There are three ways to determine how much fuel is left in a tank:
1) Weigh it when it is brand new sans fuel. Weigh it before each use
to see how close you are to this empty/dry weight. You can also weigh
it after it is full and after your first use to see how much fuel in
weight you are using for each batch.
2) There are magnet like strips sold in the bar-b-que section of most
hardware stores that are temperature sensative. You apply this to the
propae tank and it changes colors depending on the level of fuel in the
tank. The propane is under pressure inthe tank, as some of it is
released, the metal of the tank will get very cool. There will be a
marked temperature gradient in the metal corresponding to the level of
fuel in the tank.
3) Related to #2 and the simplest way to determine level of fuel in a
tank. After the tank has been running for 10 minutes or so, the tank
will begin to collect a small amount of condensation on the side. The
level of this condensation will correspond to the level of the fuel in
the tank.
Hope this helps

Many authors mistakenly suggest that oak flavours are appropriate in
IPAs, however, there are a number of reasons that I feel that they
are *not* appropriate:
1. they used European oak as opposed to American oak (which is far more
"oaky") to make the casks... there are a number of old English brewing books
that specifically say to NOT use American Oak for casks because it *imparts
a flavour* to the beer,
2. even storing beer in European oak will impart some oaky flavour, but
this takes a long time (see below) and according to Tom Thomlinson in
Brewing Techniques, the trip was about 3 months from England to India...
not long enough,
3. the oakiness of any cask will fade with use (see below)... if you were
sending a cask to India with little hope of getting it back, would you
use a brand new one or one that has been well-used?
4. some casks were lined with brewer's pitch which would completely
isolate the beer from the wood. Although, of the modern English brewers
that I know of (e.g. Samuel Smith's) who use oak casks for dispensing some
of their beers, NONE of them line the casks with pitch. I've tasted
only Samuel Smith's "from the wood" and it was not oaky, even at Ye Olde
Cheshire Cheese in London (far from Tadcaster).
I did have one other beer "from the wood." If I recall correctly, at 5pm
every Friday evening, the beerhall associated with the Schneider brewery
(famous for it's Weizen and Weizenbock) taps a wooden cask of Pilsner.
The texture of the beer was different than their regular Pilsner, but it
had no oakiness.
On the other hand, brewers of Flanders Red Ales intentionally impart
oaky flavour to their beer... Rodenbach Grand Cru is stored in huge
oak tuns (thousands of liters) for up to 18 months, until it gains an
oaky flavour and aroma. Every two batches, the tuns are disassembled
and a fine layer of oak is scraped of the inside of each stave to increase
the flavour effect. Regular Rodenbach is a blend of Grand Cru and a
much younger beer, so the oakiness is not nearly as noticeable.
Many years ago, although I don't think it is available "oaked" anymore,
Ballentine's fell pray to that notion that traditional English IPAs were
oaky and so when they made theirs, they added a special "conditioning"
stage in which they stored the Ballentine's IPA in American oak casks
for a short time... just long enough to get some oak flavour (this
can be a few days with a new American oak cask).
My tone above may imply that I'm anti-oak. On the contrary... I'm
only against the adding of oak flavour to IPAs *WITH THE INTENT OF
MAKING THEM MORE TRADITIONAL*. Add oak flavour to any beer you like,
but don't pretend that it's more traditional.
I am on the BJCP Beer Style Committee and one of the things I will
be proposing is that we split the IPA subcategory into "Traditional
English" and "American." I will propose that the American IPA be
defined as one that is made with American hops and *may* have oak
flavour/aroma (thanks to Ballentine's... just like acetaldehyde,
normally a fault, must be considered acceptable in an American Light
Lager because Budweiser has a lot of it).
There is a recent microbrewed oak-aged beer... someone will post more
on it... I believe it's called something like "Double Barrel." I've
tried it. It doesn't pretend to be an IPA... it claims to be a beer
aged in oak. I think it's a very intersting beer.
The jury is still out on where the oaky aroma/flavour in Lambics (Lambieks
in Flemish) comes from storage in oak casks or whether it comes from
some microbiota... I tend to believe that in most beers, it comes from
the latter. This is because I have tasted Jim Liddil's excellent
AHA National Competition Best of Show pGueuze and it had an oaky aroma,
despite being fermented in *plastic*. Futhermore, if I recall correctly,
Oud Beersel Geuze (Flemish spelling) also has an oaky aroma, although
it is fermented entirely in CHESTNUT casks. I spoke with the brewmaster
(Vandervelden ?) and he said he uses only chestnut casks to avoid any
oakiness from the cask. Finally, as I mentioned above, with use, the
oak loses its ability to impart flavour/aroma... some casks at Cantillon
are over 100 years old, having had more than 30 batches of beer in them.
Surely there would be no oakiness left in those casks.
>Any commercial examples of oaked beers worth seeking out?
Rodenbach Grand Cru is (in my opinion) the finest. Petrus (difficult
to find) is also a Rodenbach Grand Cru-like Flanders Red Ale. Also,
the aforementioned Double Barrel (if I got the name right) is worth
a try. If you like oaky wines, by the way, many Chardonnays (my favourite
type of wine) are quite oaky and need not as much aging as a good red wine
(so a wine of similar quality will be cheaper and can be enjoyed sooner).

Subject: PAA and Bleach
I only saw the response to the post asking about peracetic acid. I
agree with the responder; just use sodium hypochlorite bleach. If
you're concerned about the corrosive effects of bleach, you ain't seen
nothing yet. PAA is a great sterilant, but is also very corrosive.
That's why those medical sterilizers that use it have pretty advanced pH
balancing and anticorrosive chemistries.
As for making it?! OK, its a simple reaction between hydrogen peroxide
and acetic acid, and you're probably not trying for industrial
effeciencies, but this seems like a hard way to go. PAA is an
equilibrium reaction that is fairly dependent on your controls to ensure
any given concentration. If you're not clean about it, it may never
make, or may break down as fast as you do. Either way, you won't be
stabilizing it, so......?
Also, not to minimize the concern for housekeeping, but none of us
really need to "sterilize" anything. We are only
sanitizing/disinfecting to the point to give the yeast a head start.
Most routine methods/materials are adequate if used diligently.

Subject: Re: Women Brewers
Monika Schultz brings up some interesting points in # 2787 regarding
women and the "culture" of beer. Or, more specifically, the culture of
industrial American light lagers over the past 60 years or so. I
certainly agree with her that women have been sent the message that beer
is a "guy thing". And I think that this is definitely a factor in why
more women don't brew. Obviously, if men tend to identify with beer, it
stands to reason that more of them will be interested in homebrewing.
However, I do disagree with Monika's statement that "most women simply
don't like beer". I don't question your observations, but I think you
may be misinterpreting them. I find it hard to believe that gender
determines whether one likes or dislikes beer. I do know some women who
basically think they shouldn't like beer, so they aren't open to it.
(And, these are usually the women who give me "the look" when I say I'm
a homebrewer.) Friends of mine, both male and female, who really
don't like beer also tend to be the folks who don't like strongly
flavored anything.
As for me, eight years ago I fell in love with Guinness stout and Anchor
Porter. Beer like that was hard to come by where I was living.
Luckily, I had a (male) friend who brewed and inspired me to make my
own.

Subject: dried yeast pitching rates and viability
I'm not sure where this idea sprung up about getting huge pitching rates
from dried yeast...
>From DCL's own data, their yeast packets contain
> 6x10^9 cells per gram
Thus an 11.5 g package contains > 6.9 x 10^10 cells.
Viability of their yeast is about 70% when rehydrated in 23C water, thus
one package contains more than about 5 x 10^10 cells.
When pitching into 20l, this means the pitching rate is around 2-3
million viable cells per ml, which is about 1/5 the "recommended" level
of 15 million cells per ml for lagers.
Take this as you may... 5 packets of yeast per brew is getting very
pricey...
Incidentally, the DCL saflager S-189 looks interesting. Has anyone used
it? It seems that it may appear to be the same yeast as Wyeast 2278 from
the DCL spiel.

Okay,
Let's try and put this brewing myth (my opinion) to rest for once. There
are enough homebrewers reading this digest (most of us handling full
carboys with those orange carboy handles on occasion I would think) to be
statistically significant.
Has anyone ever had a carboy neck snap off on them?
I mean, geeze, no kidding, if you drop the things they break. But I

Subject: Weiss/fruit/head?
A question re head retention.
I made a tasty wheat beer - 50% wheat malt, 50% lager malt, nondescript (but
noble) hopping and a yeast kindly donated from a local brewpub brewer who
had ordered it in from Germany and which I had enjoyed very much on draught.
So a typical Bavarian type yeast.
I made 10 gallons which I split into 5 gallons with a dash of coriander, and
5 gallons with 4 lbs of frozen apricots (reheated and debugged).
The base weiss (with coriander) turned out perfectly with a beautiful head.
The apricot weiss tasted fine (apricotty) but was as flat as a pancake. What
gives?
I have made fruit beers before and never run into a total zero head. Both
beers were bottle conditioned with identical priming solutions.
I would appreciate any input which would allow me to correct for future brews.
