The answer is simple: brew Britsh beers. 65F is just about spot on for the
top fermenting yeasts used for these. I know of two books which between
them contain recipies for about 200 different British beers, including
medieval ales from before the days of hops. Don't regard this as a disaster:
a whole new world of beer has just opened up for you!

Subject: krausening
I worry about Papazians formula for krauesening. It uses O.G.,
but i think that the change in S.G. would be more
appropriate. Somebody once posted this formula to krausen a
5 gallon batch :
change_in_SG * (quarts_of_gyle)
3.2 = -----------------------------------
20 + quarts_of_gyle
which simplifies to :
64
quarts_of_gyle = ---------------------
change_in_SG - 3.2
I do not have papazians formula with me, but i do know it
gave a MUCH smaller answer. BTW... i am assuming that
change_in_SG is acuually change_in_SG * 1000. like for my
current brew, i expect to go from 1.063 to about 1.013,
hence quarts_of_gyle = 1.37 qts. i think papazians number
came out to be less than 1.
Does the above formula seem OK?

Subject: Baltimore micros
Hello - there are two micros in Baltimore City, both of which produce a pretty
decent brew.
A) Baltimore Brewing Company - just a short walk from the Inner Harbor, this
joint serves it's own (Pilsner, Dark,, Amber and one monthly "specialty")
along with some good, medium-priced, pub-food-'n'-burgers type fare. It's
located at 104 Albemarle street, between Pratt and Lombard.
B)Sisson's - the site of the local homebrew club's meetings (none of which I
have attended yet). Sisson's has pretty good deals ($6.50/pitcher) and some
fare similar to BBC's, but it also features a posh Cajun restaurant as an
adjunct. The food is good as is the beer. One of the only micros I know
that serves beers fro around the world in addition to its own! Can be
very crowded. Address: 36 E Cross St, right across the street from the
Cross St Market, between Light and Charles.
Hope this helps! Best Volker Stewart Langsdale Libr., U. of Balto.,

I brewed in my apartment in Boulder from January to May of
last year, and didn't have any problems until May. During
winter and early spring the temp. stayed between 60 and 70
degrees, fine for most ales. Some of the lighter ales had
a mild diacetyl taste, probably due to the warmer temperatures,
but I like that.
When May rolled around it became impossible to keep the temp
below 70 without paying exorbitant air conditioning bills.
The beers began tasting a little too funky even for me, and
we moved the brewery to my friend's basement in Denver, where
the temp never got above 70 all summer (eat your hearts out,
flat-landers!).
So, my advice is to go for it, but line up a good basement
or spare refrigerator for this summer.

I'm no nutritionist, but I've been reading Steinkraus' "Handbook of
Indigenous Fermented Foods" pretty assiduously. From what I can gather,
the most nutritious "beers" of the third world are those in which the
*entire mash* is fermented out. The resulting product would resemble
alcoholic oatmeal more than what we have come to call beer. There does,
indeed, seem to be ample evidence that the nutritional quality of the
grains fermented in this way does actually increase.
I think it would be iffy to do barley beers this way, since the
percentage of husks in the mash would be more than a bit unpalatable.
Using wheat malt, or perhaps better, maize malt, would result in a gruel
of greater "organoleptic" quality.
I'm hoping to do some "thick" beers here in a few weeks, using
techniques similar to those reported in this book. If anyone's
interested, I'll be glad to keep you posted.

Subject: natural CO2 vs forced
jim busch contends that the source of CO2 determines the size of the bubbles
formed in the beer. i will emphasize again that the co2 molecules do not
float around with little signs saying "i came from a sugar" or "i came from
a 5 gallon gas tank". The head formation and retention are effected by a
number of factors in beer but one of them is not the source of c02. the
size of the co2 bubbles depends on a number of factors but one of them is not
the source of the gas. if you would like to know more about what determines
bubble size and such, i would recommend an article that appeared in
Physics Today about 4-5 months ago by a Stanford chemist and one of his
post-docs.

Subject: WYEAST package breakage/recipes
Hi!
I'm new to this this conference...so hello. I am just getting
into homebrewing. I bought a pre-package ingredients kit at my local
supplier. It contained a package of WYEAST Danish Lager yeast. I followed
the directions, that is, broke the inner bag with the palm of my hand and
place it for one day in a warm place. The inner contain broke without any
trouble, I kneaded it gently and kept it at about 72 degrees F over night.
The next morning (about 18 hours later) I found the package had broken
at the seam and the mixture was leaking from the package. Is this the failure
scenario people have been talking about? Or did I do something wrong (which
there really isn't must to screw up here!). I will request a replacement,
but was curious if I happen to just get an older package or if this type
of thing should be expected on occaision? Thanx for any input.
Also, I'd be interested in any "online" recipes that anyone would be
kind enough to forward me directly...or any other useful information
to assist me in the wonderful new hobby.
Thanx all,

Geez, Eric, relax (don't worry, etc.). I've been brewing at "room" temperature
(69->71 deg. F) for 2 years now, and everything is fine! Granted, I'm not making
lagers, strictly ales, but they taste great. I do keep the carboys covered with
a T shirt or two to keep light off them, and also keep them away from the heat
registers, but that's the extent of my caution.
If you REALLY want the lower fermentation temp, why not buy a used refrigerator
and crank it up as high as it wll go?

Subject: mashing in a microwave?
A question for the grain mashers.
Mashing involves raising the grain and water to a certain temp. and letting
it sit there for a specified lenght of time. Some technics call for this to
be done in stages. ie one temp for an hour then raise it to the next temp
etc.
My question is can this be done in the microwave oven? My micro is programable
to allow this staged approach using the built in timer and probe. Anyone
have any experience with this? Comments?
Post or reply and I will summarize.
Thanks

Subject: Nutritional Value of Homebrew
"I was reading a recent (jan or feb) issue of nat'l geo over the
weekend. The main topic for that issue was "Alchohol -- the legal
drug". It contained some speculation that beer was one of the
earliest fermented beverages, and may have been the first reason
people had to cultivate grain. the article went on to claim that it
is likely that "primitive" beer was highly nutrious, in fact, in all
likelyhood brewing barley made more of the nutrients in it available
than baking bread with it. They implied this for all grains, but
barley was mentioned by name. The article then says that given today's
very light brews, modern beer has virtually no nutritive value.
"So, my question is: how nutritious can a homebrew be? or a good stout
for that matter? how would one go about making a "healthy" beer?
given the emphasis that current nutritionists put on grain
consumption, and given the comments of nat'l geo, it seems that one
could concoct a brew that would be a very enjoyable way of "having
one's daily bread" as it were ;-)"
I've thought about that, also. One of my brothers has pointed out to me that
the malt I put into proto-beer is identical to that added to 'malted' milks,
and suggests that the complex of sugars and proteins are very good for you.
Of course, the yeastie-beasties eat a lot of it up, but I'd guess that a
fair amount remains.
This would also explain how some of my barfly friends remain alive despite
never appearing to eat much of anything ... (-:
"Least my question be interpreted as anti-bread, let me state for the
record that i enjoy baking and eating bread at least as much as
brewing and drinking beer!"
I've been experimenting with making pizza, myself ... and thanks for the
beer bread recipe, Jack ...
An interesting variation on a recipe has occurred to me recently. I was in
Chinatown recently, contemplating ginger root and wondering what it would
do to my beer ... or ginseng, for that matter.
Yesterday, I was in a health food store in Santa Cruz, pondering a wide array
of herbs, and wondering what orange peel might do to a brew.
I tell you, the possibilities are infinite ...

Subject: non-brewery
I received some vary good ideas in response to my recent plea for help.
I had asked what to do about brewing in a house where there was no
basement or other cool room. For those of you with similar problems,
here are the responses:
1) Place your fermenter in a shallow pan whose diameter is greater than
that of the fermenter. Fill the pan with water. Drape some cloth
(e.g. a t-shirt) over and around your fermenter so that the cloth
comes in contact with the water in the shallow pan. The water wicks
up from the pan into the cloth. The water evaporates from the cloth
and cools the fermenter. You can cool the fermenter even more by
blowing air past the system with a fan.
2) Get a freezer that no longer works (to save money). Buy a Hunter
airstat for about $25.00 to cool the freezer. The Hunter airstat can
maintain temperatures in the required range (e.g. 60F).
The moral? When it comes to brewing, you have to be cool.

I'm not clear on what you mean by "muck around in it AT ALL." Sanitation
is the most important factor in making good beer. (Avoiding excessive
amounts of cane or corn sugar is #2 and good yeast is #3.) You should
sanitize everything that will come in contact with your wort, preferably,
just before you use it, so it doesn't get contaminated by airborne bacteria
or wild yeast or pick up the same by contact with unsanitized surfaces
in your brewing area. Once you get a routine down, sanitation will not
be such a big pain anymore -- but no less important.

Protect your wort/beer from all light, if you can, especially fluorescent
and daylight. Yeast don't need any light at all, and you're right:
light struck beer smells skunky.

Great. Leave it under the box.

Could be. Depending on the yeast, the temperature, how much you aerated
your wort, if you used a starter or not, etc. etc., it can take anywhere
from 4 to 48 hours to see activity. I may have recently killed a starter.
My basement is about 10 degrees colder than my kitchen. I culture yeast
in my kitchen. I recently made a 500ml starter from a package of Wyeast
#1028 (London Ale). It was going well as I poured 100ml of that starter
into another 500ml of wort the morning I was going to brew. In the
evening, that starter was going well. While chilling the wort to pitching
temperature, I had the starter in the basement with me. After a few minutes,
I glanced over and noticed that the airlock was going in the wrong direction.
The cooler temperature was contracting the starter and the air in the
starter bottle! Not that it was a big deal or anything, I decided to put
the starter in the warmest place in the basement -- the heater room:
*on top of the heat plant* (DUH!) for 30 minutes. Well I pitched the
yeast and had no activity for 36 hours. It was still too early to worry,
so I leisurely poured 100ml more from the first starter into the primary.
8 hours later, fermentation was active -- after 8 more hours, blowoff
had begun. There's no way of telling if the original 600ml starter took
48 hours to start or if the 100ml starter did. In any event, the moral
of the story: don't let the temperature of the yeast change too dramatically
or get too high and don't worry.

Hmmm MeV going out of business leaves Wyeast as sole suppklier,
but this isn't a classic monopoly, it's not like they used predatory
pricing or other agressive business tactics, just good service, good
quality, and a good product (though pricey). Too bad more American firms
don;'t have the Wyeast ethic.
On a related note a local homebrew shop owner has gotten hold of commercial
yeast culturing equipment and is considering doing limited production runs
I have been lucky enough to get some test batches and the quality so far
has been good. Perhaps if other local industrious types take up this approach
fresher, less expensive yeast can be had. This will of course cut into
Wyeast business, but that's capitalism...
