Subject: Re: Decoction debate
Howdys, gentlepersons.
I thought that since the subject was on the table, I'd toss in a small
by-the-way from my brew kitchen. I have been doing decoctions habitually for
almost a year now, but not so much for any particular flavor reason. I've
been doing it, believe it or don't, because I wanted my step mashes to go
faster. I brew on a stove and it is an outdated and inefficient old
wiretangle electric. I hate it. If I let it heat the mash on one burner, it
would scorch and take hours, so I turn on the heat low undet the main mash
and take out the decoction heat it on another burner it while the rest is
slowly heating. It's really just a way for me to use two burners at a time
when stepping up. If the main mash isn't hot enough after adding back the
decoction, I adjust with a little water from my HLT (another pot that I'd put
on to heat several hours before). Sure, it thins the mash a little, but it
doesn't make a huge difference. A little extra proteolytic action wouldn't
hurt in the witbiers I've been making this way anyhow. Speaking of which,
one of said wits was a 1st place winner several times over. A very pleasant
surprise.

Hi all,
Dave Harsh and Steve Alexander make some very good points
about the pros and cons of decoction in response to a question
by Bob Pelletier. Dave, in particular, questions whether
you can duplicate the flavor of a decoction mash by adding
Munich or melanoidin malts to the grist.
A few years back, I tried to do just this by adding
DeWolf Cosyns Aromatic malt to certain German lager styles,
with pretty good success. >>

Subject: Colorado Brewpubs
Phil wants to forget about the purple mountain's majesty and
get to drinkin' some good ol Colorado beer.
Well Phil, since you'll be real close, you'll have to start
at the Wyncoop Brewery in Lodo. Most everything they serve
is pretty tasty.
Then head south on Kalamath to the Breckenridge Brewery.
They do allright too.
Keep going south on Kalamath till you get to Alameda and
make a big left hand curl. East on Alameda, north on Santa
Fe, then west on the next little street. On your right is
the Heavenly Daze Brewery. Real Nice IPA, too bad the
Chapter 13 Ale is gone... The only thing I wouldn't
recommend is the pasta salad...
After that, wobble on down Kalamath again until you hit
southbound I-25. Watch that right hand merge, it's a bitch
when you're legally intoxicated...
Weave south to County Line Road and the Rock Bottom, (you
can see it just before the exit, on the right) They brewed a
killer IPA that has strawberry esters in it. Gotta ask how
they did that....
Along about now, you'll be looking for a cozy ditch to sleep
in for awhile, because that's just the beginning.
What with Coors, AB, New Belgium, me, and about a hundred
regional and local craft brewers, We make more beer than any
other geographically distinct region in the world!

> I suspect its the yeast.
I don't think so, tho the autolysis might be what is responsible for weizens
having a short shelf life. I use 3068 and have no problem with head retention,
in fact I almost have the opposite in that a 2" head sits on my hefe's and
won't go down, so that I get foam up me nose :). This is true of a weizenbock
that has been in the bottle for 6months+, and I generally have quite a bit of
yeast sediment.
As Jeff R said, drop any 50-60C (protein) rest completely. FWIW, I mash with a
40-64-71C schedule, and the 40 is a loooong rest of 30-60 mins, this helps both
reduce the wheat gums, and also the formation of ferulic acid which is a
precursor to the clovelike phenol, 4-vinyl guiacol. And I generally do a double
decoction with that schedule.

Hi! I'm also actually from Lexington, KY, (and now live in San Diego,
CA -- have for about a year) but spent a lot of time two years ago up
in Cincy.
If you are near Blue Ash, try Watson Bros.
Downtown, go to Nicholsons. It's not a brewpub, but an upscale
Scottish bar and restaurant. The tap selection was excellent last time
I was there -- many beers I've very seldom seen in North America on tap
(and then, mostly in Ontario). Naturally they have a good selection of
other traditional Scottish libations as well.

Dave Riedel attacks a timely question (to us Northern hemisphere types) ...
>The one-year-old crop, stored identically, went brown
>nearly immediately. It has been theorized by one of
>my friends that perhaps the hops were not thoroughly
>dry when I froze them.
Possible - even probable - water and picked leaves don't mix. My wife
used to drive me crazy by cutting basil just before the first frost then,
despite my protests, rinsing it off before hanging it to dry. Wetting the
leaves is a formula for brown useless basil.
The major mechanism in leaf browning is phenol oxidase enzymes reacting with
phenolics in the leaf. The phenol oxidases are there to protect more
critical
cell constituents from oxidation by sacrificing the abundant phenolics.
Phenolics also have structural, growth regulation and pesticidal(fungi,
bacteria and even herbivore) roles in plants. Wet warm conditions and some
cell damage increase the rates. It's not entirely clear that the hop
browning itself
and the oxidized and polymerized phenolics directly cause any flavor damage
in
beer (these are less soluble and pretty protein-philic), but wet warm
storage
conditions and cell damage can *imply* loss of the humulones and essential
oils we're after. IOW I wouldn't throw out hops with cone surface
browning but I also wouldn't buy brown hops since they may have experienced
serious mishandling.
I've recently frozen some undried fresh hops just to see how this comes
out - I don't see any good reason why this isn't a good storage method aside
from the difficulties measuring by weight and the extra storage costs which
make this commercially untenable. There *may* be green hop flavors that
appear but that will have to await some experiments.

Dave R says ...

>Over the last two-three weeks I've noticed an

I just polished off a pils that was getting old (brewed 3/10)
and the hops aroma and bitterness were both fading making
it sweet and showing off some flaws more clearly. Can't say
but maybe it's just the hops fading and other flavors showing
through.
Hops aroma, flavor and even bitterness don't last forever,
especially with very imperfect HB kegging procedures. The
best HB kegging methods I've read of will introduce air in
the headspace at rates far above commercial bottling
standards. Oxygen and nitrogen are each implicated in the
flavor/aroma theft.
Beers don't travel well in time or space - good beer
is a shortlived local phenomena.

Dave Harsh notes ...

There is a "clear difference" ? Great to hear that but where is the
evidence ?
I've tried comparative brews (decoction vs step) and I was surprised
to see that differences were modest and variable. Louis Bonham did
a comparative brew and triangle tasting that found no decoction
advantage. M.Lewis at UCDavis published his informal tests that
over a period of years found decoction & step mashed beer not
even reliably distinguishable! So far I've heard of no test result
evidence to support the idea that decoction matters - much less that
decoction matters in a big way. Two (or perhaps 3) informal tests
are weak evidence - tho' far stronger than a mere hunch.
>People have claimed that
>is no effect on flavor and I have to question how many decoction mashes
>they've actually performed.
I certainly never said or implied decoction has no flavor effect.
Any two brews, even a single brew split tween kegs and bottles will show
flavor differences. No one can claim decoction makes no flavor
difference. The question is - are these differences significant,
reproducible
and are decocted beers sufficiently better so to justify a very long brew
day.
I think that decoction has a small advantage in flavor - but smaller than
most 'true believers' accept unchallenged.
So here's a test that shouldn't be too hard to perform . I'd wager that a
bevy of beer judges cannot ID the decoction brewed beers in a flight in a
statistically significant way. (My side-bet is that they would
preferentially
pick beers with more dark malt as the decocted ones - even if they
weren't.)
- --
The evidence that NO-SPARGE brewing makes maltier, better tasting
beers is far clearer than that decoction does. I'd suggest that beginners
try the very simple no-sparge method before concerning themselves with
a tedious decoctions.

Subject: Headless hefeweizen /LA Fair
Regarding the current thread on Headless Hefeweizen;
I am currently working a booth at the LA County fair where we have been
pouring a very tasty hefeweizen with nice banana/clove flavors, but no head.
It was brewed by a local brew-pub. I don't want to say where, but
apparently some of the slightly larger brewers have the same problem.
BTW, if you are in S. Calif., the LA County Fair is currently going on
through 9/29. If you go, stop by the "Beer Tavern" we built to serve the
beers from the commercial beer competition. At any given moment, we serve
10 different beers. It has been a real experience and we have been able to
introduce a lot of Joe sixpacks to good beer.

Subject: Decoction with less labor
Just add my two cents to the decoction thread:
I use a decoction method that only adds about an hour to the mash
session. I'd like to take credit for this idea, but I got it from
George DePiro a couple of years ago. Basically, I haven't seen any
real character difference between this method and a double decoction
(I've done a few of those). Don't know how this might compare to a
triple decoction; I've only done one of those and will probably never
do another.
In any case, my method is as follows:
Saccharify your mash at your favorite rest temp (145F-155F). I use
about 1.2 - 1.4qt/lb of water.
After the mash has converted, use a large strainer (the kind with a
handle), to scoop the mash into your decoction pot. As you extract the
mash, try to take as little of the liquid part of the mash with you as
possible. In general, I take most of the solid part of the mash into
the decoct pot. The idea is to try to leave as much of the
enzyme-laden mash liquor behind as you can.
The mash solids in the decoct pot should be dry, but not too dry. If
necessary, I will add a little brewing water (or even some of the thin
mash left behind) back in to the decoct pot so that I can just see a
little liquid in the spaces between the grains in the decoct pot.
Things should look like thick porridge or oatmeal at this point.
Insulate the main mash so the temp doesn't drop too much (you may even
need to apply heat of you don't have a good insulator), and begin
boiling the mash in the decoct pot. Note that it may take some time to
get this up to boiling without applying massive amounts of heat.
You'll need to stir quite a bit.
Once the decoct hits boiling, let it go for 20-30 minutes, stirring
all the while. If the mash gets too dry, add some brew-water as you
see fit. The whole proecess should take you less than an hour, and
smell pretty good.
After you are done boiling, re-add the decoct back to the main mash
slowly to bring the whole thing up to about 160F or so. Rest for 30
minutes, then either mashout or do whatever your regular sparge
routine calls for.
Note that you will probably have some scorching on the bottom of your
decoct pot, which will be all but impossible to remove by scrubbing. I
generally remove this (after rinsing the pot), by putting about 3/4
inch of water in the bottom, and adding a generous portion of lye.
After soaking overnight, I pour off the lye solution (carefully), and
the scorched material is either gone or very easy to remove. CAUTION:
Lye is highly caustic and extremely nasty stuff. Use goggles, gloves
and great care when handling it. DO NOT use lye on aluminum pots.
I've done side-by-side comparisons using this decoct schedule versus
adding aromatic specialty grains on samples of Bohemian Pilseners, and
definitely preferred the decocted versions. On the other hand, I'm not
sure that on other beers that are brewed with predominantly munich
malts that there is really much of a difference. I'm hoping to do a
side-by-side comparison of a couple of mostly-munich dunkels in the
near future.
Hope that helps -- m

Are you sure that Cesky Budejivice is really the Budvar yeast? I just
brewed a couple of beers with this one (not pilseners, tho) and
haven't noticed a tendency for the yeast to produce much diaceytl at
all, or to be particularly under-attenuating. I should, mention here
that I'm brewing dunkels made from primarily continental munich malt,
but I would expect _stronger_ attenuation using a pilsener grist.
Also, these beers are not done lagering, so I still don't know what
the final character of the beers will be.
I did notice this description of this yeast at the White Labs site:
"Pilsner lager yeast from Southern Czech Republic. Produces dry and
crisp lagers, with low diacetyl production. Attenuation: 75-80 "
This doesn't sound much like the Budvar yeast profile. I was under the
impression that this was the Budvar yeast myself, until I saw this
description. Might be nice if someone from White Labs chimed in if
they're reading this. I may pitch a doppelbock on this yeast next. If
this really is the Budvar yeast, I may choose another style.

Subject: Hopping rates
Dear HDB'rs
When I use pelleted hops I let them sit in the wort while I cool it for
yeast pitching. If I use whole hops I usually put them in a bag and pull the
bag out prior to cooling. Is yanking my bag (come on, you know what I mean)
a mistake here? How can I find out the variance of whole or pelleted hop
isomerization in these two methods as far as the aromatics are concerned? I
imagine those bittering hops that have been sitting in a boil for 60 minutes
are about tapped out so they shoulnd't be of concern- or is this not true?
Many thanks for any help,

Subject: Pretzel Salt Origins
Alan has asked what pretzel salt is. The honourable Jeff Renner has
graciously told him, along with the rest of us where to get it. However,
what Alan really wanted to know was what it is. I can help the
collective out on that account.
Let me introduce my self. I am Bill Slats, CEO of Pretzel Integrated
Salt Services Ltd. Our primary business is mining pretzel salt. Our
ancestors left behind enormous quantities of pretzels. Those pretzels
have spent eons underground. My company mines those pre-historic
pretzels and processes them to make pretzel salt. Many cheap Yank
knockoffs are on the market, but I can assure you that the best of
pretzels have pure Pretzel Integrated Salt Services crystals on them.
So...... when you make pretzels, spend the extra for quality and make
sure you have pure Pretzel Integrated Salt Services crystals on them.
Now, I can only hope that the collective will find the charity to forgive
the Honourable Jeff Renner for dealing with superficialities, that the
Honourable Pat Babcock and Honourable Karl Lutzen can find it in
their heart to forgive my crass commercial announcement, and that
the Honourable Jeff Renner will find the kindness to not flame me for
such outspoken criticism of his handling of such a weight question.
With Tool in Hand,
