Thanks Al, and also the several others who posted or sent me this
correction (in one form or another). The 42 and 35 (pts/lb/gal) numbers
work pretty well so I'll be using those next time. At anyrate, thanks to
the 1 lb of honey I added, the beer ended up nearly right on target and
has fermented down really fast. It was down to 1.017 (OG=1.048) when I
racked it after one week in the primary. Tasted practically done and
pretty damn good, too (similar to Bass). I may be ready to bottle next
weekend at that rate. For those out there using Lagglander DME and
fighting with high final gravities, try sub'ing a little honey for part of
the Lagg to get a dryer finish.
Also, just so people don't think I'm a total loon and am operating from a
vacuum the rule of thumb I was operating from in formulating the recipe
was from Mark Steven's and Karl Lutzen's book 'Homebrew Favorites', 1st
printing, 1994. On page 6, bottom paragraph :
"If you are going to brew an extract based brew, you will typically need
about 1 pound of extract for every 10 points of gravity. For example..."
etc.
Now, I note in retrospect that the vast majority of actual recipes in this
book do not use this formulation, but unfortunately, I happened to be
using as the rough model for mine one of the few that seems to.
Specifically, the Bantry Bay Irish Red Ale on p. 35, which calls for a
total of 6 lbs DME + grains in a 6.5 gal recipe to get an OG of 1.048.
Unless there is a typo somewhere, I don't believe this recipe can possibly
achieve the target gravity.
Hopefully, Mark is reading this and will excercise the ol' editorial red
marker before the book goes to a second printing? :-)

Subject: Help on recovering from Bonehead Move
I stated before that I had been away from brewing for 6 months, and my
rustiness has surfaced early on...
I was planning on brewing an SNPA (from Tony Babinec's recipe in Cat's Meow),
so I popped a fresh American Wyeast, let it puff up and then proceeded to make
my starter. I sanitized everything, poured the wort into my starter bottle
and poured the contents of the package into the bottle also. Then to my utter
horror I realized that I had not cooled the wort down !!!! (the kids were
crying, it was late, there was a hurricane, locust, honey it's not my
fault).............
Now that you have stopped laughing at me, is there any hope of recovering from
this bonehead move? Or have I sent my entire army of yeasties to a scorching
death?
As a fall back, I took my last bottle of actual SNPA, poured it into a glass,
swirled the remnants and poured them into the COOLED starter in hopes of a
recovery.
Oh well, I guess this is why they have dry yeast.

Subject: Scotch Ales, cereal, 60 C rest, and decoctions
Hey HBDers,
<prepare for exceedingly long post from beginning all-grainer>
I am pleased to announce the successful results of my first two all-grain
batches, a head-to-head comparison (almost) of Wyeast Irish 1084 and Wyeast
Scottish 1728. I say "almost" because the comparison was done on two different
batches of identical grain bill, not a split batch, with some slight
variations here and there. As a scientist, I grow weary of exacting
experimental conditions and so I like to feel a little less restrained and a
little more creative in my brewing hobby---why brew if it's not fun?! The
two brews were intended to be scottish ales and fell somewhere between the
export class and the strong scotch ale. Here's the pertinent info on each:

After the discussion here regarding protein rests and well-modified malts,
that rest will probably be eliminated if I try to repeat these recipes.
Batch #1 (Irish) was an overall superior brew, with better carbonation
(possibly too much), head retention, body, and maltiness---it also had a very
nice perfumey quality that seemed to be a product of the yeast (as no flavor
or aroma hops were used). Batch #2 had a lower extraction efficiency that I
attribute to my being impatient the day of brewing. ;) Both brews ended with
fairly high FGs despite a huge 1-gallon starter for batch #2 and much
aeration with an aquarium pump system. Explanations??
The flavor profile of the Wyeast Scottish was more than a little
disappointing given the high praise it was given in private e-mail. It
exhibited very little of the characteristic "peaty" qualities and absolutely
no smokey flavor. The batch was also less carbonated and more bland, with
less body and head retention but greater clarity and the same nice malty
finish. Color between the two was identical.
I would encourage any beginning all-grainer to just do it---it's a little
challenging but really satisfying. The recipe for batch #1 above will make a
fine brew, but I would eliminate the protein rest and pump up the grain bill
to make it a strong scotch ale. ;) Question on specifics----email me.
- ------------------------------------------------------------------------
SPENT GRAINS AS CEREAL:
I forget who suggested this.
Well...I was feeling adventurous and tried it. The verdict?---a little
chewy, tasted like something between beer and cattle feed, sticks in the
teeth something fierce, and they weren't kidding when they said high fiber.
I threw the rest in the compost pile, where all future spent grains are
headed. ;)
- ---------------------------------------------------------------------------
60 C (140 F) REST:
Can someone please enlighten me as to what exactly is going on in the mash
during this rest? Is this considered the beta-amylase rest? Why 140?
- ---------------------------------------------------------------------------
ANOTHER FIRST----A SINGLE DECOCTION:
I brewed my very first lager this past weekend using a simplified single
decoction mash similar to the one in the decoction-faq. What great fun!!
The grain bill for the Munich Dunkel was:
5.0 lbs German Durst 2-row pilsner
2.5 lbs German Durst 2-row munich
1.0 lbs American 2-row munich 10L
1.0 lbs German Durst 50 L crystal
0.5 lbs cara-pils
I used a 40/60/68 mash, with a 25% decoction pulled during the 60 C rest.
The decoction was heated to 68 C, held 15 minutes, heated to 100 C, and
boiled 10 minutes before being infused back into the main mash. The mash
came to rest at 65 C and was direct heated to 68 C. I expected a fairly
quick conversion, but it kept failing the iodine conversion test. Conversion
was finally verified after 1.5 hours at 68 C. My questions: Did the
decoction destroy so many enzymes that conversion was slowed down
considerably in the main mash? Or does the German 2-row grain just take a
bit longer to convert? Is this typical? Or....does some other explanation
exist?
Sorry for the HUUUUUUUUGE posting, but it's all brew-related. Flame me if
you must. Thanks for any help. private/public---however you want it.

I just put a new game in mirror INFO-MAC
ref ---> .../mac/info-mac/Game/Abaccus-10.hqx
This game play with french words (5 letters), alls words are into a dictionary
file, my purpose is to convert it with all english 5 letters words in order to
do a multi langages game.
My problem is to do an english dictionnary file with all 5 letters words
all words must be in alphabetical order (easy) with a difficilty level
attach for exp :
- table 1 " lecel 1 for word "table" easy word "
- desks 3 " level 3 ? "
- Rabat 6 " level 6 it's a town " etc...
All words comes with 6 levels of difficulties, but a good knoledge of
english is necessary, in my french dictionnary up to 5400 words are
included, I suppose more than 5000 words can be found in english.
Normaly kinds can play with level 1 and 2, level 3,4 are more diffucult
and level 6 seem to be impossible, this last one is only for word check.
User word reply is ckeck and must be in any dictionary file.
Usualy words are from the "scrabble" game.

Subject: Little Tapper Keg
I just purchased a small aluminum keg at a flea market and am trying
to figure out how it works. Its made by the Reynolds Aluminum Company
in the state of New York. It was obviously used for commercial beer
and would be exchanged for a new keg once empty. I've been using the
Corni Keg for my draft system but this would be perfect for transport
to other places. The keg appears to be turned out of aluminum and
holds 2 1/4 gallons U.S.. Theres a plastic tap on the front for dispensing
beer.
On the back is a plastic plate which says "Contents under pressure, do no
tamper". After tampering with it I discovered the keg contains what
appears to be a re-fillable, self contained CO2 unit. I think it fills
by use of an adapter similiar for filling basketballs. I anyone
familiar with these kegs? How do they put the beer in it at the factory?
Any information on these kegs would be greatly appreciated.
Sincerely,
Wade

Mark Godar asks about replacing his 24" nylon spoon with a wooden

I recommend a stainless steel paddle from a restaurant supply house. You
can get them in 3- and 4-foot lengths. I do not recall the price (mine
was actually a gift), but you need not worry about coatings or
treatments of the wood. If you can't come up with the the scratch for an
SS paddle, get a 21" spoon, also available from a restaurant supply
house. This should run less than $10.

Yep - he most certainly did say to re-aerate - scared the
life out of me too until I tried it.
The purpose of dropping is to leave behind the dirty yeast
head and as much trub and dead yeasties as possible. The idea is
to aerate and rouse the remaining yeast so that it will re-establish
a strong working colony in order to finish fermentation properley
and in order to recreate a strong yeast head. This, to an extent,
depends on the yeast strain but the few British strains that I've
used seem to take to it well - beware anybody using Wyeast #1007
German Ale yeast - I suspect that this doesn't like the dropping
system and seems to slow down dramatically afterwards. Another
thing that is to be taken into consideration is whether or not
you practice open fermentation. I cover my fermenting bin with its
lid (loosely laid on top) after pitching and wait until a strong
cover of yeast has formed at which point I remove the lid completely.
I drop, normally, at 48 hours after pitching and again loosely
cover the bin until the yeast head has reformed when I, again,
remove the lid. The bin remains open for another day or two when
the yeast covering will normally subside and I will once again
loosely cover the bin with its lid until the beer gets near to,
or reaches, FG (if it hasn't already done this). At this point
I rack (without aeration) into a clean fermenting bin for 24 hours
prior to racking, again without aeration, to a plastic pressure barrel.
So Gillian, give it a try. I'll put in a disclaimer that it
works for me and GW and, I assume, other readers of his book - take
reasonable care and it should work for you. It also works for Morland's
of Abingdon and Marston's of Burton and used to be practiced by many
other commercial breweries - the main reason for them stopping, being
that it is expensive on space and equipment.
To qualify my experiences - I've been brewing all-grain brews
and using these methods for 8 months now. In that time I've used 100Kg
of Pale malt (just finished my 4th 25KG sack) which suggests that I've
done 25-30 batches (can't remember exactly). In that time I've only
had two problem brews - the first was when using a live yeast from a
local independent brewery which seemed to go into some form of shock
even before I got to dropping the beer. The second was with the Wyeast
#1007 strain that I mentioned above - after dropping, this seemed to
slow to a halt and the resulting brew developed a bad taste. I did
do a succesful batch with the #1007 yeast but again, this seemed
unhappy about the dropping process - I stopped using this yeast after
that.
Cheers,
Brian

This would be easy to do by using an electric range "continuous" control. They
do just exactly that - turn power on and off with a small internal bimetal strip
as the controlling element. These controls are also used in ceramic kilns...
The last time I bought any for my wife's kiln they were $30 each - (15 years
ago) though they may have been much less expensive had I bought them somewhere
other than the ceramics shop. I would assume that this is what the BruHeat uses
for it's control also.
My gut feeling is that the dimmer you are using probably does a better job as it
effectively reduces the power by chopping the power 60 times a second rather
than turning the element on and off a couple times a minute. This would result
in the element not being brought to full heat for the time the control is on
potentially being more "gentle" to your wort.

Somebody will surely correct me if I'm wrong, but my recollection is
that late aeration (e.g., during "dropping") will increase both

Subject: Re: In defense of the AHA
Jeff Hewit mentioned that you don't know what led to the rift between
the AHA and the Beer Judges. The AHA withdrew from the BJCP because the
steering committee that consists of appointed officials representing
both the AHA and the HWBTA (Home Wine and Beer Trade Association) approved
the addition of 3 elected representatives from the homebrewing community.
This didn't suit the AHA's desire to have full control over the BJCP
without any input from the members, which you have to admit is very unusual
for that type of organization. The Beer Judges had no plans to overthrow
the AHA, but only wanted some input and information about what happens in
their organization.
I agree that Zymurgy is a decent publication, especially with the
improvements that have taken place in the past year. The advertising is
a little bothersome, but it has some usefulness when you're searching
for ingredients and I'd rather have it there than see the price of
the magazine increase. The AHA has significantly helped the craft of
homebrewing, but remember that they are motivated by profits and will do
anything they feel is necessary to protect their position.
Jeff also mentions that he brews beer to satisfy your tastes, not to win
awards. That should be everyone's goal, but being a beer judge has
significantly helped my knowledge of brewing and beer styles. I have been
able to help dozens of homebrewers in local clubs trace problems in their
beers to specific areas of their brewing procedure, and it's nice to see the
quality of their beers improve when the problem is addressed. So be
careful not to underestimate the benefits of having trained beer judges in
the homebrew community, especially when we're not motivated by profits.

My brother and I stir our mash with a 9-iron. No foolin'.
The angle of the club head is such that, with a slight twist
of the wrist, you get excellent grist motion from bottom to
top. The shaft is strong and has a very nice grip for wet or
cold hands.
We brew 10 gallon batches and mash in a Gott cooler like yours.
I designed a slotted 1/2" rigid copper manifold that uses four
parallel pipes joined with tees and elbows to form a square.

I avoided using solder by cutting the pipes just right so that
the manifold corners press firmly against the cooler walls. The
manifold falls apart when removed from the cooler for cleaning or
storage. When in use, the manifold can not come apart and I
never hesitate to bang the 9-iron against it when I stir. We
have used this set-up for 14 batches and have never had a mash/
sparge problem, even with grists of ~20% rolled oats and all 2-row
grain (pipe is slotted halfway through every .3".)
We broke two of those nylon spoons before switching to the golf
club. I can't imagine a better stirrer than a 9-iron. Give it
a try. I hope this info helps.

Subject: Lager
I am making my first shot at formulating my own all grain recipes (until
now, I have either used other people's, or have slightly modified someone
else's). I thought I'd run it by the collective wisdom of the hbd to collect
feedback prior to brewing.
What I'm shooting for is a Honey Ginger Lager. I want it to end up a little
on the high gravity side, full-bodied, good head retention, and not too
hoppy.
Grain Bill:
8 Lbs German Pils 2-Row Malt
.5 lb Wheat Malt
.5 lb Dextrine
.5 lb Crystal - 10L
I am adding the wheat malt, dextrine and crystal for body and head retention.
I was planning a two temp mash (152F & 158F) unless someone can tell me why a
protein rest would be needed.
I will add two pounds light clover honey to the boil.
I will also boil in 4 oz. grated ginger root. I know it sounds like a lot,
but I have used it in an extract beer with excellent results. It's sort of
toxic for the first 4 months, but after six it becomes a dry, snappy, excellent
refreshing beer.
Hops:
1 oz. Perle (not traditional, but I have them around) 8.0 alpha for 50 min. boil
1 oz. Willamette (Ditto) 4.0 alpha for final 2 minutes
I anticipate Final results to be around 1.060 OG, 34.5 IBU, and 3.6 Lovibond.
Any suggestions on this?

Subject: IMMERSION, STIR OR NOT
I have been lurking here for some time, gleaning mountains of data for
the improvement of my brewing. Many thanks to all who have contributed.
I stir the wort while cooling with my home made immersion cooler. It
was made of 3/8 OD copper. I used some of the coil (50FT) that was left
over to make a secondary immersion coil. This coil is 4IN in dia. and
about 4IN high. I chill the wort with the main coil until I do not feel
any heat in the pot when I put my hand against the outside. I then hook
the secondary coil in between the faucet and the main coil. The coil is
put into a mixing bowl full of ice cubes and water. This cools the tap
water before it goes into the main cooler. This method has been working
great for me. It takes less than 20 min. to get down to below 50 deg.
I also pinched the output tube partly closed on the main cooler to slow
the water flow (more efficient?).

Kieth can't remember where he saw the bit about sour-mashing a portion

sour-mashed and then pasteurized and added to the fermenting brew.

There has been much discussion about calculated vs. measured IBU's in

numbers on the raw hops as gospel. It would seem that if you are going to
try and fit actual IBU numbers to a formula, you should also send in a
sample of the hops used to see what their actual amount of alpha acids
are. The difference between actual alpha acid and the number written on
the package may explain some of the wild variations

Subject: RIMS Temperature Control
Thought I would report the latest results from our experiments
with our system re: temperature control, heating rates, and so
on. The full description of this system is currently in The
Brewery (http://alpha.rollanet.org), although I need to update
that article in a bad way. We've added a bimetal dial-type
thermometer to the outlet tube coming off the mash tun, followed
by a ball-valve shut-off.
We half-filled the tank with hot tap water and began circulation
with the pump valve wide-open. The temperature stabilized at
120F, and we fired up the burner wide open. Every 60s I read
the thermometer and recorded the results. At two points we shut
off the burner completely, and looked for temperature drift.
Mind you, this is using *water only*, but the data still gives
us useful information for predicting behaviour during a real
mash. Based on our past mashing experiences, I tend to agree
with Jeff Burton (HBD #1656 same subject) that we'll be able
to recirc with a full-open control valve. In any case, I
recorded twenty temperatures over twenty minutes, reading the
thermometer to it's limit, then did a linear regression on the
data to yield 2.7F/min; the data was *very* linear.
Of possibly more importance than the heating rate is the fact that
when the burner was shut off, there was *no* perceptable temperature
change whatsoever for over 10 minutes, at which time I could just
detect a miniscule temperature reduction. NO OVERSHOOT. Again,
this is with water only--but I have no reason to expect grain to
change the behaviour provided the wort flow rate is similar.
This data indicates thermometer response to the water temperature
is at least as fast as the water response to the heat input. It
tracked beautifully and didn't move a hair's breadth after burner
shut-off.
[Suddenly I felt as though readers may think I'm challenging the
need for or wisdom of automatic control--no, my *only* purpose here
is to invite others to witness the progress of system development
as it happens. This will expose both the success and failure of
the development, but hopefully stimulate your corrective comments
prior to our failures.]

use sucrose to brew up a batch of cheap grape wine in the closet,
and it seemed to work fine :) How does glucose (aka dextrose, corn

Subject: Chiller results / Canadian suppliers? / Cloying beer
The polls have closed in the "to stir or not to stir" counterflow chiller vote.
The volume of responses precluded me from replying to everyone personally,
but i would like to thank all of you for you input, including:
Bob Hall, Ed Hitchcock, Richard Scotty, Spencer Thomas, David Cutkosky,
Pete Murphy, Domenick Venezia, Matt in Montreal, "N4331B" (?), Jim Ellingson,
Steven W. Schultz, Dan Sherman, Rich Larsen, Fred Cost, Dion Hollenbeck,
Christopher Gall, Jason goldman, "GRMarkel", Charles Jackson, Jeffrey Van
Deusen, Tom Ausfeld, bruce DeBolt, Steven Smith, Kurt in Oregon, and anyone
else who's name I missed.
of 26 respondents:
19 stirred their wort during chilling
7 did not
of 18 stirrers (the 19th didn't answer this question):
12 stirred part of the time
6 stirred all of the time
Only one person suggested a possible infection problem, and he felt that it
probably wasn't due to the stirring (he stirred part of the time).
There were a number of interesting points made by respondents:
-Many felt the risk of infection due to uncovering the pot for 15 minutes to
be minimal. Especially if a healthy starter was pitched.
-stirring is a lot less tiring than grinding the grain ;) .
- some people "stir" by moving the chiller around. Saves dirtying a spoon.
-people cover the pot with every kind of covering from saran wrap to aluminum
foil, to lids with holes in them.
-The average chill time was around 20 minutes, with some people taking over
half an hour, and one or two people much longer than that.
-lots of people are worried about offending brew gods and inviting hexes by
claiming to be infection free.
-Dion Hollenbeck has a motorised stirrer coming down from a hole through the
lid in his pot. Motors are cheap.
-Ed Hitchcock has all his coils curled around in a disc shape like a stove
element. This is held in place by a foot which rests on the bottom of the pot.
Convection currents do the stirring for him. The coils are held ~1cm below
the wort surface. This distance is somewhat important. Much lower and the
liquid above it doesn't cool. Much higher and the contracting cool wort will
drop below the level of the chiller. Designs for a float device anyone?
My conclusion: continual stirring probably isn't worth the effort. Ed's idea
shows the most promise, with Dion's a close second. Partial stirring is not
a bad compromise either. But one of the big reasons for getting an immersion
chiller was to be able to drop out cold break easily. If you stir, you still
have to wait for the break to settle after the wort is cool. I often brew
in the evenings, so the extra 15-20 min is too long. Natural convection
currents are far more elegant a solution. I believe some experiments are in
order.
