Subject: My mashing technique
Many thanks to Mike Charlton, who confirms my feelings of inadequacy :-)
My worries about my mashing technique are:
*) My thermometer may be off. I don't think this is true, but
since I want to replace it anyway, It's worth a try.
*) I may not let conversion go long enough. Two hours seems like
a long time, but I should try for 2.5 sometime, with an extra
heat boost to stay above 142 dF.
*) My lauter tun may be doing me in. This I doubt; it's a double-
bucket affair, made from some heavy-duty stiff plastic 18 qt.
food "buckets". There's about 8-10 oz. space below the spigot
that of course gets wasted, but I really doubt that that's
where all the good stuff is going (it would have to be the
consistency of honey!)
*) The 2-row is not diastatic enough to convert the wheat and
dextrin malts. I am too ignorant of biochemistry to assess
this potential problem.
When mashing, I go out of protein rest up to about 152 dF (I've been
shooting for a fermentable wort). I always stir carefully to avoid
overheated zones in the kettle. After I reach the correct initial
temperature, I cover the kettle with my insulated box (my wife knew I
wast a lost cause when I built that). Temperature drops to the mid
140's in an hour or so, so I stir and boost the heat at that point.
Note that if my thermometer's off, this process would be severely
affected.
My lauter tun is insulated (a recent addition; I used this nifty stuff
that's basically two layers of small bubble wrap covered with
reflective foil), so there is only moderate heat loss during the
sparge. I recycle wort with an intermediate re-heating stage. I have
wondered whether I'm waiting too long before ending the recycle and
going to the boiler. The final runnings come out pretty damn pale,
though.
Thanks for the hints!

Subject: Re: Brewpub Practices - tangent on aging
I was recently in Toronto for a few days. While there I tried
to hit as many brewpubs and try as many micro-brews as I could. At the
Rotterdam I went on a tour and spoke with the brewmaster. While talking
with him I was surprised to discover that they do not age their beers
very long by our standards. He serves the lagers after four weeks, the
light ales after one, and something like a porter after two. I commented
on how my recent porter, although very good after a month, was phenomenal
after three months. He said that as professionals they had far greater
experience (easily believed) and that since they could control temperature
and pressure, they did not need to age things as long as we would (this
was not said condescendingly).
Do people out there believe this totally? I'll agree that they
may not need to age quite as long as we do at home. However, two weeks
from start to finish for a porter? Four weeks for lagers? Doesn't Bud
age their lagers for 6-8 weeks? I should note that I was not overly
impressed by their beers or that of their sister brewpub in Toronto
(the Amsterdam) although it was much better than your mass-market swill.
The other brewpub I went to there, Dennisons, was better. It is partially
owned by Prince Luitpold of Bavaria. Was he the one on the Beer Hunter?
One point to raise about the aging of beer in brewpubs is that
they may not have the space. If they were to double the aging time of
their beer, they would need twice as many storage tanks, and they may not
be able to afford that, or have the space for it.

Use the slurry from the secondary; the slurry from the primary may
have trub, precipitated hop resins, or other undesirable products
in it.

Subject: Re: Patriotic Duty
Well, this time we don't have anyone in the family ``over there'',
and perhaps it's just as well, but I noted a shipping suggestion
theory; note that no one is actually going to try to send anything
across the pond without being sure that it's legal over in Saudi
Arabia. Stinking hole. Insert anti-arab prejudice here.
Not only might a dark beer look remarkably like a brand-named
carbonated beverage if placed in a plastic 1-litre bottle, but
the stuff might have a little bit of sediment in the bottom.
Of course, no one would pour that sediment into a batch of diluted
malt-water, and leave it to sit for a few days, if that were against
local regs, and therefore no one would notice that they got a better
product than the other guys who were using bread yeast.

This is the perfect opportunity to write a couple of FYIs.
"Publications for the beginner" is a good one.
"NYC-area suppliers" is also good.
"General beginner information" has already been written by Rob Gardner.
Anybody want to take a stab at listing some of the basic beginner
publications and a small narrative on each? I will if no one else
out there feels qualified.
How about someone from NYC to start a listing of suppliers?
Let's do it!

From: mcnally@wsl.dec.com
Subject: Gravity grief
I'm starting to believe that my problems with low starting gravity (see
some previous messages from me) may have something to do with my sparge
technique or hardware (or both). From my general feelings about how
the world works, it seems that one problem might be that my grain bed
is *too* deep when I have a lot of grain. I realize that there's risk
of compromising the cleanness of the sparge (i.e., I might get more
draff), but perhaps the problem is that the sparge water's capacity to
dissolve the sugars is exhausted before it gets through the 18 inches
of grain. Perhaps I could try a double lauter tun approach, and split
the mash between them. Hmmm... I also found that the settling space
below the tap level in my tun is bigger than I had thought; tilting the
tun might get me a couple points.
What are commercial lauter tun geometries? Dave Miller mentions that
commercial breweries apply the sparge water to the grain bed very
carefully to avoid disturbing it. That only really makes sense if the
bed is shallow. Maybe I'll look around for fatter buckets from which
to make a lauter tun, and use the fat one for heavy recipes.

Subject: Grain brewing references
I am preparing to enter the world of All-Grain-Brewing.
I already have Papazian's "TCJOHB" and would appreciate it
if any of you experienced brewers could suggest informative references
for the "WHY, WHAT, HOW and WHEN" of this science. Thank you in
advance.

Subject: Chicago, Illinois Water Analysis
I saw the post on the water quality for Burlington, Ontario a while
back and that prompted me to get the Chicago analysis. The two are
really quite similar, especially numbers that may be imporatant to
home brewers (hardness, pH, etc.). I assume that Burlington gets its
water from Lake Ontario (Chicago is of course Lake Michigan water), so
maybe this analysis is typical for all Great Lakes water(?).

Subject: Lager and FYIs
Mike Schremp asked about starting lagers. The one lager that my brew partner
and I made went very well. We just started it like any old beer--which for
us means room temp (~65-68 deg F.) and putting it in a fridge after it got
going. It went pretty well. Ended up being one of our best batches.
The comments on FYIs sounds really great. I don't understand the details on
creation or use or the ramifications on adminstering & such. But the basic
idea sounds super for the novice--and for the advanced!! This raises a
question I'd forgotten about. I've tried to get stuff from the archives
but have failed. Could someone post or e-mail me a little primer on how to
retrieve old stuff?? Many Thanks.

Subject: question...
How come brewers don't have to include the ingredients on their products?
If Oscar Meyer is required to proclaim the ther world all the nasties included
in making there bologna, why don't the makers of Olympia beer have to tell
us what kind of adjucnts are included--Bud is kind enough to admit that rice
or corn or something is added.
Just a question.
