Ahem. I beg to differ on short boil periods, even with extracts.
There are several things being accomplished with the boil. One of
the most important is bringing out the hops; you want to get the oils
as well exposed to the water as you can. A longer boil period allows
you to get a better hops flavour. Adding your own hops of course
makes this argument even stronger.
By boiling the stuff, and racking as in a two-stage ferment, you get
rid of them. When you rack (strongly advised: I always use the two
stage method, and get clear beer this way) you also get rid of a fair
load of dead yeast. I rack again at bottling time, not bottling from
the carboy (with its own accumulation of dead yeast) but from a
bucket sterilized for the purpose.

Yes and no. Yeasts which can withstand colder temperatures, the first of
which was discovered by Carlsberg (see elsewhere in HD#158), are what make
lagering necessary. These types of yeasts, which are now commonly called
lager yeasts, could ferment at colder temperatures and subsequently produce
less by-products such as esters. This resulted in a beer flavor that we
associate with lager beer. The colder temps required longer brewing
periods and the beer had to be stored (in german, lagered). The only reason
I said no is that you could use lager (bottom fermenting) yeast at higher
(ale) temps and get good tasting beer - but it would not taste like lager.
Anchor Steam beer (San Francisco, CA) is brewed with lager yeast at warmer
(more ale-like) temperatures.

Subject: Introduction and a Few Questions
Hi Everyone
My name is Jim Somerville. I have been brewing for about a year
now, my last batch being a dry malt powder and honey brew. The
alcohol content is quite high >7% by my estimates. Is this
normal for having started with 30% honey? I have been drinking
it for a few days now, but the one I had last night had a strange
mouth feel, which can best be described as kind of gelatinously
slimy. Any ideas as to what causes this? I boiled the wort for
an hour as usual, and there was quite a lot of trub at the
bottom of the primary (I use 2 stage fermentation). Could serving
temperature have anything to do with it?
My guess is that it is caused by the dry malt powder. I have
noticed that some recipes call for dextrine malt. Is it the
same stuff as "brewbody"? The dry powder I used was not brewbody.
On the topic of sanitation, is it worth boiling the bottlecaps?
On the topic of yeast, should a person bother to add yeast
nutrient to an all malt batch?
If someone is keeping a canonical list of questions and answers,
please send it to me.
-Jim
