1) There are lots of good extract recipes out there. Try Byron Burch's book,
Zymurgy Mag. or find some other homebrewers and ask them. Also experimenting
is fun

2) The wavelengths which destroy beer flavor are 400 - 520 nm. Ref.
The Practical Brewers, Master Brewers Association of America, Madison, Wis.

3) I once again vociferously concur (oooh big words) with Dick Dunn on aging.
Part of the entire point of homebrew is to produce a FRESH product! Do you
think CAMRA fought so hard to preserve cask conditioned ale because they
like old beer?? Someone once told me an anecdote abuot a taste test. It
seems European beers that were flown in fresh for the testing were blind
taste tested by consumers against those which had gone through the regular
distribution networks which insure that you get old beer. Consumers
preferred the old to the fresh! Theory is that it is what they are used to.
Maybe those of you who like aged beers are too used to drinking old,
improperly handled beers which is why you like them that way. As one who
does a lot of intentional damaging of beers in order to train beer judges
I'll tell you that with few exceptions (recipe dependent) it is freshness
or death! One last point on this topic. Hop flavor degrades with age. If
you have to let your beers age in order for the hops to come into balance
then you're making them too hoppy to start with.

4) Oh Contriare Dick. Yeast definitely does impart flavor into beer. Maybe
you phrased it wrong but if you consult the troubleshooting 87 issue you'll
get an idea of just how many flavors yeast puts into beer. Yeasty is usually
associated with sulfury flavors like DMS, or Hydrogen sulfide. These arise
in a number of places but the classic yeasty flavors come from yeast decay
and autolysis (yeast digesting themselves).

5) Boiling grains. Byron Burch's book tells you to boil darker grains. My rule
o thumb is to only boil grains when astringency is desired. When pray tell is
this, well certain drier stouts and/or porters call for it. I just made a
great Imperial Stout and boiled the black, chocolate and roasted grains
for 15 minutes, and what I couldn't strain out fully for a whole hour with
no excessive astringency. It's all a matter of balance.

Carbouys-

I have a friend who got hold of 3 pyrex carbouys. He has never used them sice
he didn't know what had been in them and how to assure that they hadn't
had evil nasty chemicals which couldn't be purged. Of course the other problem
is tracking down a stopper since they have really wide necks. My friend got
his at some sort of garage sale, but he was always the kind to acquire junk
and then find a use for it rather than vice versa. If you buy them new they
are indeed very expensive.

I once broke a carbouy via thermal shock. That was when I broke down and
sunk $10 into 10 ft of 3/8 outer diameter copper tubing which I use as
an immersion chiller. It takes 10 - 15 minutes to cool the wort, now I
pitch my yeast almost immediately. Despite ongoing debate about using copper
I haven't noticed any flavors from it (believe me I'd notice, I've been
judging 2 years now am at the certified level and frequently host flavor
perception seminars to keep my taste buds in tune).

For Aaron Fager your friend in Poughkeepsie should contact
Hennessy Homebrew
470 North Greenbush Rd
Rensselaer NY 12144

518-283-7094
T-F 5PM - 9PM
Sat 10AM - 3PM

Hennessy takes credit card orders over the phone, mail orders and
if your friend is really uptight it's under a 2 hour drive from him.
Orders are shipped within 5 days usually and UPS will take only 2 days
to get to him from here. We do have customers that drive up from his area
to make large orders.
All hops are refrigerated in the store as is all yeast (liquid and dry).
Turnover is high (Hennessy is Crosby and Bakers largest customer in the
NorthEast) so supplies are typically very fresh.

disclaimer: I work 1 night a week (wednesday) for Dan mostly as a favor
since he prefers to have the store staffed by knowledgable homebrewers
instead of dumb clerks. (assuming you consider me knowledgable).
Dan also sponsors our clubs competition (a local competition for club
members and hennessy customers within reasonable distance of Albany).
Both of us work day jobs and so far nobody is close to getting rich
off this place and it looks like we ain't never going to.
