Subject: re: dry vs liquid yeast; debunking the RS Ale Momily
This is a question for Steve Stroud, who yesterday posted the results of a
culturing experiment using RS Ale Yeast. When the yeast was plated were
there any visible signs of contamination? I.e., did any non-yeast cultures
grow along with the yeast?
Cheers,

Well, presumably that is *exactly* what you are doing. The
AHA competition is going to be analyzing your entry. Of course,
convincing the UPS counter guy is another issue.

Well, this is an ongoing problem, and not related to liquid yeast
use alone. What about fermenting in glass vs. plastic vs.
stainless steel? Many winners ferment in stainless steel, for
example.
Most of these examples show nothing but that more experienced
brewers tend to win more in competitions and tend to do fancier
things when brewing. Beginners tend to do things much simpler
and tend not to win as often. But one would expect more
experienced people to win more often anyway.
So, how do you determine what is technically better? You do
studies, with as many factors controlled as possible, and with as
little known to those tasting the results as possible. Some
clubs have sponsored these studies, some are done for magazines
such as _zymurgy_. But in general, there is no funding for
homebrewers to perform these types of studies (any advice on
applying for a grant to do this?).
In the absence of thorough and convincing scientific studies
(and look at how much argument there is among the scientific
community even after some of these studies are done), beginners
are more likely to just follow the advice of more experienced
brewer acquaintances or to look at what competition winners do.
In general, their beer will improve from this advice, but there
is also no easy way to quantify the benefit from any one
particular item.
So, proving causality is difficult, but imitating procedures or
ingredient usage of good brewers is about as good a method as most
people have of improving their brewing and their beers.

Subject: Munich Dunkel ?
Does anyone have an extract based recipe for a Munich Dunkel?
I've checked the Cat's Meow and back issues of Zymurgy, and the
Traditional Beer Styles edition doesn't give any hints to the
extract brewer. Any help is appreciated.
Also, since this years AHA Conference is in my backyard,
relatively speaking, I'd hate to miss out on all the fun. To those who
have been there before, Are any of the events open to nonregistered
attendees? Can I go down there, party with all the other homebrewers
and not attend the conference? What about CLub Night, does this exist
and is it open to all AHA clubs? I'm being extra nice to my wife but
that will probably just get me a weekend away without the conference
fee.

Subject: chipped porcelain brew pot
Hey there,
I've got an enamaled porcelain brew pot with a quarter sized chip in the bottom. Every time I take the pot out to brew a batch I've got to work hard to remove the recently formed rust on the exposed steel. Does anyone have any suggestion (aside from buying a new pot) on how to fix the porcelain? In the mean time, will a little rust be harmful to the wort?
Next, two requests.
Can someone please mail me a copy of the postscript " brewsheet.ps" from mthvax.cs.miami.edu ?
I would like to brew a barleywine similar to SN Bigfoot Ale. Are there any recipes around?
Last, one idea.
I've found a bottle washer that works pretty good. I unscrew the sprayer head on the kitchen sink sprayer and use the hose to quickly rinse bottles. Don't forget to put it back before your wife uses the faucet and gets squirted.

Subject: More revealing stats: liquid vs dry yeasts
Folks,
I do agree with the sentiment that "if all the winners at the AHA competi-
tion used liquid yeast, all that might prove is that all of the participants
used liquid yeast." However, here are some more *complete* statistics:
1990 Competition (1548 entries)
technique entered placed 1st, 2nd or 3rd
malt extract 22% 20%
extract + mash 27% 20%
all-grain 51% 60%
glass fermenter 85% 86%
plastic 10% 8%
stainless 5% 5%
2-stage fermentation 74% 77%
single stage 26% 23%
dry yeast 33% 16%
liquid yeast 67% 84%
(source: 1990 Special Issue, Zymurgy, vol. 13 no. 4, p. 61)
The conclusion upon first seeing these is that liquid yeast is the most
important thing you can do to improve your beer, more so than mashing,
lagering or fermenting in glass over plastic, although each of these
seems to be a "step up".
Now, the caveat here is that more experienced, better brewers tend to use
more advanced techniques, so that results attained may be the result of
the technique OR they may be the result of the beer having been brewed by
a more experienced, better brewer.
To me it doesn't matter, the fact that more experienced, better brewers
tend to use a technique is a strong recommendation to me that *I* should
use said technique. The conclusion is the same.
Besides, the jump from 67% to 84% in liquid yeast cited above is *tremendous*
evidence that this is a great way to improve your beer. But again, it is
only correlation, as statistical types will likely point out.
I don't have the numbers on me from 1991 although they were published.
I think the jump in liquid yeast was *not* as high, but that was partly
because the overall % of entries using liquid yeast jumped quite a bit.
Hope this helps, sorry to beat a dead horse (but note that apologies didn't
stop me from posting :-),

Subject: Homebrew shops in New York
Hello. I have followed HBD some months now and it has been very
interesting. Some words about my problems. I am a homebrewer
from Finland, and it is the biggest problem, because of the lack
of the ingredients. We have grain, of course, and I have done
malts myself (advices about malting procedures would be helpful).
But here I can't buy hops (I have tried some hops for medical
purposes, but they were really bad) or yeast (I have found two
dried yeasts, "Top fermenting" and "Bottom fermenting", but there
was no other information about their types). Now one of my
friends is going to New York next month and I should want to know
if there are any homebrew shops in New York or in Albany(NY). The
question was asked some time ago, but I never saw an answer.
Thanks in advance.

Subject: Budvar & Budweiser
"Budvar" and European "Budweiser" are one and the same. To be more
accurate
accurate, Budwesier is the name of the beer itself, and Budvar is
an abbreviated form of (Ceske) Budejovice Pivovar which means simply
Budweiser Brewery -- the name of the comapny.
The bottles themselves have the word "Budweiser" in large, orange
stylized script. A very nice looking bottle, if I may say so.
One of my best beer experiences concerns the real Czech Budweiser
and it makes me absolutely sick to think that AB will someday own
the name/factory (I am a fatalist). I think that when a country
in an economic situation is facing massive investment from a mega-
company like AB that it's very tempting to give in in the name
of "broadening markets," etc. If I understand the Czech people at

that was picked out by my friends as a good starter. i have also just
started to recieve the daily homebrew digest off the vax. in recent issues
there has been alot of talk about dry vs liquid yeast. at this point i am
using "beer kits" with the package of dry yeast in it. i really dont have
an opinion yet on what type of yeast is best(if there is one). my question
is, once you discard the dry yeast package from the kit and start using
the liquid stuff, how do you match up your recipe with the liquid yeast
other than knowing thats it either lager or ale?

Subject: Larger questions / Wyeast starter problem ?
I am attempting to make my first lager and I have a few questions / problems:
1) I made a starter for the Wyeast #2007 (Pilsen) yeast I bought for this
batch. The yeast seemed to like the starter, as the fermentation lock was
riding high and sediment eventually formed on the bottom of the bottle, but
krauesen never formed. When I went to pitch, I tasted the starter and it
didn't taste right. I hesitate to say that it tasted sour, but did have a
certain tang to it and it sure didn't taste like fermented wort. It may
have been a bad move, but I pitched anyway. So my questions are:
Did I infect the starter somehow, or this normal behavior for this strain
of yeast ? (I think krauesen should have formed)
Did I just make 5gal. of fertilizer ?
Do people normally pitch the entire starter, or just the sediment ?
Am I worrying too much ?
More details on my procedure and timing:
On Sunday morning I broke the inner pouch of the yeast package that I bought
the day before, which was date stamped Feb. 19. By Sunday evening the
package had swollen and was bulging at the seems, so I made a starter by
disolving 3/4c dried malt extract in 1 1/2 qt boiling water and boiling for
45mins. I put about 14oz of this wort in a sanitized 22oz bottle, cooled
it, and added the contents of the yeast package, then fit the bottle with a
fermentation lock. I then let it sit at room temp until I pitched on
Wednesday am.
2) Assuming all goes well with the yeast, should I lager in the carboy or
bottles ? Miller suggests the bottle approach, and Papazian seems a little
vague on the whole subject, what do other people do ? And if I do lager
in the carboy, should I rack to a secondary first ? And how long is a good
lagering period, or is it the longer the better ?
Thanks

Subject: IBU <-> HBU revisited...
About a week ago I asked about HBU to IBU conversion. First of all thanks
for the great response. Th summary of which follows:
Josh Grosse (amoung others) writes:
<paraphrase> HBU's may be estimated as
IBU = HBU * (%utilization / (gallons * 1.34)).
Several sources give the %utilization number as 28% for leaf, 30% for pellet,
given a 60 minute boil of "standard" gravity wort (1.040-1.045). Plugging
it all in we get IBU=HBU(or AAU)*~4.5.
While persuing Micheal Jackson's New World Guild to Beer, he references
45 IBUs as extremely bitter. Now my beers with 10AAUs for 60 min. are
not overly bitter. Why? Because like most partial mash brewers, I only
boil about 2.5 gallons of wort. This means my boil has a gravity of about
1.090 for my "standard" beer. And my utilization is obviously far less
than 30%.
Does anyone have a formula for %utilization, incorperating gravity
and boil time?
(I understand that this information may be buried in a Lotus 1-2-3
spreadsheet authored by the infamous Mr. Richman.)

This is almost the same setup I use: a 10 gallon Gott water cooler and
a plastic collander which just fits in the bottom (beats the heck out
of drilling holes!).
I mash and lauter in it, and I do make sure I mix it up well. Might
even be better to add the grains to hot water, instead of the other
way around. My brew partner insists he gets better efficiency and a
clearer sparge by doing a stove top mash, but I haven't verified his

Pick up Fred Eckhard's book, The Essentials of Beer Style. It sounds
like exactly what your looking for, plus he compares different
commercial examples of a given style so you can taste what he's

Subject: Full Sail Golden Ale recipe
In HBD #825 I posted a recipe for a Full Sail Golden Ale taste-alike.
(I neglected in the posting to state that the recipe was for Full Sail
*Golden*, not Full Sail Amber or Brown Ale.) Anyway, I received a
number of interesting and helpful responses to my posting. One of the
most enlightening of these responses was from someone who had obtained
some information from Hood River Brewing Company suggesting that some of
the ingredients used in Full Sail Golden Ale are different from the
ones indicated in my recipe. The source of this information, which
indicates that Hallertau and Tettnanger hops are used in both Full Sail
Golden and Amber ales, is a *coaster* from the brewery itself. My recipe
calls for nugget hops, however, because the *label* on Full Sale Golden
Ale bottles states that nugget hops are used.
Can anyone help us resolve this contradictory information? I have been
told that "Jamie" of the Hood River Brewing Company could do so--does
anyone know how to get in touch with him?

P.S.--Meanwhile, I just tasted the first bottle of the second batch of
ale I have made with the recipe I posted, and the taste is pretty
similar (albeit not quite as succulent tasting as Full Sail Golden
Ale). My impression is that the Hallertau/Tettnanger hops taste is
pretty evident in the *amber* ale, but I can't pick up this taste in
the *golden* ale. I could be wrong, though, and am curious about the
outcome of this one...

> Last week I brewed an all-grain scottish ale. The recipe
called for 2 oz of roasted barley and 3 oz of chocolate
malt. Can any of you enlighten me on the relative flavor profiles
of the various kilned malts and roasted barleys?
I know nothing about "profiles" but I would be amazed if two ounces of
roasted barley could be detected by even the most gifted nose.
I decided to put my own nose to work and made three batches as follows:
one lb roasted barley
one lb roasted malt
one lb each
The balace was Klages and a total of 9 lbs for 5 gal.
I was unable to tell the difference by taste or smell between roasted malt
and barley. They both tasted and smelled like coffed to me.
They both had a distinct coffee flavor early but towards the end of the keg,
it was not detectable as coffee just a richer flavor. In a side by side
comparison, the roasted barley has a bit of an oatmeal kind of taste and we
(my wife and I) liked the roasted malt better.
Either was a definite improvement on our light generic ale.
The combination batch is in the secondary, waiting for an empty keg. It has
a pronounced coffee taste but I suspect if it mellows out like the other two,
it could be quite excellent.
So, I think you are waisting your time with ounces.

>I know where I stand on the issue of dry vs liquid yeasts: I changed to
single cell cultures a long time ago and haven't looked back.
Although the rest of your article is science at its best, not looking back is
definitely not very scientific.
>Hidden in the midst of the on-going dry vs liquid (single cell culture)
yeast debate is what appears to be a universal condemnation of Red Star Ale
yeast. Well, I'm here to come to the defense of Red Star Ale yeast and to
break a momily:
>Red Star ale is actually a nice, clean somewhat unattenuative yeast. It's
the other crap inside the yeast packet that causes all of the problems.
Let us make sure we have correctly identified the "momily" in question.
Your article proves conclusively that selecting for survival of the drying
process does not restrict the other characters needed to make a good beer.
It also proves that the drying/packaging process (as done by Red Star) is
subject to contamination.
Both are totally reasonable conclusions and not inconsistant with my position
before or after reading the article.
>To answer this question, Sheri Almeda cultured Red Star Ale yeast on agar
plates and isolated four single cell yeast cultures.
I am having a hard time understanding what this means. Are these four
colonies from each of which a single cell was taken? Were they chosen
because they were the same or because they were different?
The results would indicate that they were probably the same or similar enough
to be irrelevant.
What else did they find on the original culture? If the contamination is
biological, they should have found either bacteria or an evil yeast in the
culture.
It also sounds like the control sample was taken from a different packet.
>This experiment also points out the problem with using dry yeast. You just
never know what's going to come out of that little packet. Even though the
dried yeast was very viable and got off to a fast start, the final product
had a contamination problem."
This also points to the solution to the problem. All the discussion about
the selection problems is null and void. We need only come up with a sterile
drying and packaging process.
However, it is becomming obvious that the real problem may not be what all
this talk is about.
The use of a liquid yeast could be (and probably is) only a bit more
complicated then pitching a properly re-hydrated dry yeast. If the results
are as much better as users contend, then the resistance must lie elsewhere.
The obvious elswhere is price. There is an great reluctance to use something
that costs 10 times what an acceptable alternative costs.
There are lots of ways the user can reduce his cost but it takes more effort
and unless he does a lot of brewing, he risks the evils he is trying to
avoid.
I suspect making money culturing and selling yeast to homebrewers is marginal
at best and aside from simplyfing the package, not much can be done to reduce
the cost at the current levels of production.
>So there you have it. The problem isn't RS ale yeast, it's the _purity_ of

Translated: The problem is what's in the package of RS ale yeast.
It all boils down to the same thing. Don't use it!
The only way they will ever fix it is if people stop buying it.

Nothing comes to mind at the moment :)

It now seems to be largely responsible for a great deal of frustration.

Is the Devil making his packaging decisions?

Sounds like he has been reading my mind. But why "new strains"? Why not
sell the tried and proven ones without starter? Why not just a lower cost
option for brewers willing to do a little more fiddling?
My advice is to pick a standard ale and market the hell out of it. If they
got the volume up, there is no reason why they could not drive dry yeast off
the shelves. They are destroying any chances of economies of scale by
spreading themselves so thin.
Hmmm. No more free advice.
Can someone recommend a "standard ale" yeast?
Stand by for:
ARF GENERIC LIQUID ALE YEAST
Still only a buck.

Use an old darkroom trick ...
To keep dust from landing on your negatives, etc., you walk around the
room with an atomizer spraying water mist high in the air and letting it
settle.
For brewing I do this about a half-hour before brewing, and I use some
dilute sterilizing solution instead of plain water.
It makes a noticeable difference in the darkroom, so why not in
the home brewery ...
