Subject: Advertising vs. Informing (my 2 cents)
Hi all,
Since I am the one who posted about the upcoming California Festival of
Beers in San Luis Obispo, I feel like I should add my 2 cents about the
ongoing thread regarding advertising. I also work at our college radio
station, and I guess I regard the HBD like a public radio station which
disseminates news and public service announcements to the community when
they are of service and interest to the community and benefit non-profit
organizations.
I wish to reiterate that the proceeds from the California
Festival of Beers benefit the Hospice of San Luis Obispo County, a
non-profit organization providing care to the terminally ill and their
families, plus bereavement counseling. Therefore, I believe that ticket
price is tax deductible. Plus, I have no affiliation with either the
festival, or the hospice. I just like beer.

In a previous article Don Rudolph inquired about the

BEER magazine, Spring 1994 edition. No, I do not have permission,
but I am doing this to give beer the good representation it
deserves.

I know that by just saying beer, that it is not too
specific. The beer analysis was taken from "Typical Beer
Analysis" by Molson Breweries, meaning in my opinion a
fairly generic brew.
To further quote the above article, "The ranges in nutritive
values are important and point to the need for better consumer
access to nutritional information on beer."
"...The moderate consumption of beer significantly
reduces the risk of heart disease...According to a 1985 study
done by Johns Hopkins University Hospital in Baltimore, people
who drink beer moderately and regularly are ill 13-25% less
often than the average person, taking into account age, sex,
and income group."

Subject: Weizen questions
Hope this goes thru ...
I just got Miller's book out of the library (I love Madison),
to inspire myself to get a batch of Weizenbier going (it _is_
summertime) ... and read that "these days the Bavarian
breweries usually filter out the top-fermenting yeast and
pitch a stabe bottom-fermenting strain at bottling time."
A few questions:
(1) Is this true? If so, why does the yeast in those
weissbiers taste so yummy, while I have to decant my
homebrew off the yeast in my other beers 'cause it's lousy?
Has anyone tried adding lager yeast at bottling?
(2) At what temperature does Wyeast 3068 best do its thing?
(Or Yeast Lab Bavarian Weizen -- I'd use it if anyone
would attest to it).

From: Art Steinmetz <asteinm@pipeline.com>
Subject: JS Mill, Malted Wheat, decoction, etc.
I made a Weizen a couple weeks ago. My first attempt at
decoction and I was nervous. It was surprisingly easy. TIP: I
entered each mash step as an appointment in my electronic
organizer so an alarm went of to prompt me each step of the
way.
I bought both Belgian and domestic wheat malt (DeWolf-Cosyns
and Breiss). Big difference in appearance! The Belgian grains
were about twice the size of the domestic. Plump is how I'd
characterize them.
I used the Belgian for this Dunkelweizen. The JS mill did a
fine job of crushing the wheat malt although their size made
turning the handle much harder than 2-row barley. I read
somewhere that wheat doesn't have husks. Could of fooled me.
Wheat malt has a skin of some type, whatever you want to call
it.
I was breifly called away during the sparge and the water level
got too low. This resulted in a stuck sparge. To unstick I
cut the bed with a spatula. Blew into the outflow hose to
clear the manifold slots and then recirculated a couple quarts
again until the wort cleared up. No big deal. The spent grain
bed had the consistency of pudding. You could slice it into
cubes and put 'em on a plate!
The beer is bubbling away now. If I didn't have three young
children and have to bargain with my wife for every minute of
free time I'd do this again.

Subject: List of brewpubs
Lisa Prescutti requested a source of phone numbers and addresses of
brewpubs. "The Great Beer Trek: Revised and Updated"(a book for lack
of underlining ability), by Stephen Morris is a reasonably good source
for brewpubs and breweries nation wide. I recommend calling any place
you plan to visit as some of them no longer exist. It is put out by
Stephen Greene press of Penguin (I have no affiliation).
There are also books put out for east and west of the Mississippi, but I
can't recall the name right now. The San Francisco Brewing Company is
featured on the front cover of one. Ask your book store.
Thought this might be of interest to more than just Lisa (lots of good
beers and friendly people), so posting it on the HBD.

Subject: Re: Beer as Food
Don Rudolph asked for an analysis of a "typical" beer. From my "Complete
Book of Food Counts" by Corinne Netzev..here goes. I've listed a few
beers out of the book.
For a 12 oz serving:
Becks - 148 calories, 1.7 grams protein, 10 grams carbos, 0 gram fat
Budweiser - 144 cal, 1.2 grams protein, 11.3 grams carbos, 0 gram fat
Carlsberg - 149 cal, 1.2 grams protein, 11.9 grams carbos, 0 gram fat
Michelob Classic Dark - 158 cal, 1.5 grams protein, 14.4 grams carbos, 0 g fat
Rolling Rock - 145 cal, 1.4 grams protein, 10.4 grams carbos, 0 g fat
By way of comparison to other foods:
Glass non-fat milk (2 cups) - 180 cal, 18 g protein, 26 g carbs, 0 g fat
2 whole eggs - 150 cal, 12.6 g protein, 1.2 g carbs, 10 g fat
Hostess cupcake - 170 cal, 2 g protein, 32 g carbs, 8 g fat
Alcohol has 7 calories per gram, compared with 4 calories/gram for protein
and carbohydrates, and 9 calories/gram for fat.
But, what does that mean? IMHO..if you are eating sensibly and exercising
on a regular basis....a few beers every now and then aren't going to hurt
anything. Just watch out for all the other things that tend to accompany
those beers (ie fatty foods, drinking before going to bed,etc). I consider
my occaisional homebrew as a special treat..something to be savored and
enjoyed. And for gosh sakes..if you are dieting and have thus cut down
on your beer consumption....make sure that you enjoy the beer that you
DO drink!
Hope this helps,

Does anyone know of any scheduled beer events (micro beer tastings,

'round these parts. TIA.
While I have your eye's attention, the wife and I went to a local
pizza establishment and ordered a pitcher of Sam Adams Lager on tap.
It did not taste like any Sam Adams that I've ever had in a bottle:
Much fresher and refreshing with a finish that reminded me of...
well... err... Fruitloops. This was not a bad thing, just unexpected.
Has anyone else noticed this? The beer wench (sorry ladies :)) said
it was a fresh keg, just popped an hour ago.

Subject: Choc cherry stout problem
I went to bottle my chocolate cherry stout today, and - horror! - it tasted
simply *awful*! I got a few people to taste it, and descriptions ranged
from "off milk" (denied by my brother, who has drunk off milk) to
excessively bitter or sour. This sounds like an infection, but there is
no white crud and the beer that I made and brewed right next to it at the
same time turned out perfect. The yeast starter that I made for the choc
cherry stout was quite strange though - no krausen, and an audible fizzing
noise similar to that made by carbonated soft drinks. I haven't tossed it
out yet, but unless there's something I'm missing here it sounds like I'm
going to have to. Anyone have any ideas on why it would have turned out like
this? BTW I made it with:
1 can of Munton's dark LME (1.8 kg)
1.5 kg pale DME
300g Cadbury Bournville Cocoa
The juice from 900g canned sweet dark Oregon cherries
The yeast was a generic buck-fifty dried ale yeast.
Thanks,

Subject: Mash/Lauter Tun design & conversion question
Greetings -
I've been lurking here for some time now, and I've just done
my first all-grain batch. Truly a terrific experience, and fairly painless
as well. I'd like to share my mash/lauter tun design, as it worked
perfectly without requiring any damage to be done to the Coleman ice chest
it was made from. I also have a simple (I hope) question regarding the
starch conversion test.
The Tun -
The mash/lauter tun is the square-ice-chest-with-copper-tube-manifold
variety. As this was a new ice chest, we wanted to join the manifold to the
drain without damaging the ice chest. One previous post suggested sticking
the end of the manifold out the drain and sealing it up with food-grade
caulk. An excellent idea, but it prevents using the cooler for other things.
I found (like many others, no doubt) that when you fit a 3/8" id
siphon hose over a 3/8" copper tube, the overall outside diameter allows a
perfect force fit with the inner diameter of the drain hole on the ice
chest. So, just shove the siphon hose over the end of the manifold tube,
and thread the hose through the drain from the inside of the ice chest.
Pull the hose through, and push the tip of the manifold into the drain.
A perfect, water-tight fit. Now just plop the hose on top of the chest
to stop the flow, or find an inline valve. The Coleman lining also seems
to tolerate the sparge temperature - no visible damage/blistering.
Of course, spending one's life as a mash/lauter tun is certainly
a noble enough existence, but it would be a shame if the thing never got
to see Yosemite!
The Question -
And now for the simple question. I bought some tincture of iodine
from the pharmacy for my conversion test, and did a test about 2 minutes
into the mash to see what a failed test looks like. Behold, no color
change! Repeat the test with varying amounts of mash and iodine. Zippo!
Looking on the bottle, I saw the words "decolorized iodine." Hmm...
Did I use the wrong stuff? Did I do the test wrong? (1T of mash in a
glass with various amounts of iodine). Opinions, anyone?
Peace and good brewing to all -
Charlie

From: Craig Pepin <ckp@acpub.duke.edu>
Subject: Fermentability of Bourbon
A question: Is there any residual fermentable extract in Kentucky Bourbon
(or for that matter, any kind of whiskey, made from corn or malt?)
I recently started using cheap Kentucky bourbon (Ten High brand, 80 proof)
in my airlocks instead of sanitizing solution. In case my fermenters
pulled airlock fluid into the fermenter because of a drop in temperature, I
reasoned that whiskey would taste better in my beer than bleach. After
three or four batches (most of which had some slight infection in the
secondary which kicked in after the yeast had done its job, leaving a thin,
but not undrinkable beer) I started noticing that the whiskey in the
airlock would get cloudy after a week or two. Closer analysis revealed a
slight brown residue at the bottom of the cloudy airlocks, and the whiskey
no longer tasted like whiskey. (A little sour, actually)
No I *know* that yeast should not grow in such an alcohol rich environment -
which is why I'm pitching my barley wine with champagne yeast. But are there
beer spoilers out there which could be infecting the airlock bourbon (and
subsequently getting into the brew)? And is there any residual extract,
maltose, dextrins, or whatever, in conventional whiskey/bourbon? Could
the alcohol be evaporating off, (occurs at room temperature (ca. 70)
and in my lagering refrigerator) leaving behind whatever is left over in
whiskey (and reducing its sanitizing ability?) I assume they don't call it
Kentucky "mash" for nothing.
Sincerely,
Disoriented in Durham

Hi -
I'm a relatively new brewer (3 batches in bottles so far) and I have a quick
question. 2 of the 3 batches I've made were following Dave Miller's
_Beginner's Bitter_ recipe. After a few weeks in the bottle (2 and 1 week) I
tried some, and the taste is... unusual. What I'm looking for are two things:
1. Has anyone brewed that beer and found it to be good, bad, or indifferent,
and
2. What's the best commercially (US) available beer that I could use as a
comparison?
Thanks for any advice. Post or email fine.

Jack, you make a great product, but the whining and blatant competitor
bashing on the net is unbecoming. As the owner of a Glatt mill who has
extensively compared mine to a friends Schmidling mill, I've got to say
that most of your criticisms are at best unfounded, and at worst just
plain false. The mills are EXTREMELY equal, each excelling in one way
or another. I especially find offensive your attempt to compare the
price of the adjustable Glatt to that of your fixed roller mill in an
attempt to claim that they cost the same. (rather than comparing to
your adjustable mill, as would be more appropriate).
In addition, you try to imply that your mill is easier and better for
motorizing. The Schmidling mill that I have worked with has a handle
that is VERY difficult to remove, and has very definite warnings telling
users not to motorize it. OTOH, the Glatt that I have has a removable
handle, and running it at 2500 RPM with my electric drill has caused no
damage or degradation of the crush. I compared crushes at various
speeds when I first got the mill in order to verify this.
I did not intend to keep a "my mill is better than yours" battle
going, but your self-advertising manner is offensive. Try letting your
customers sing the praises of your mill, rather than doing it yourself.

I'm not sure why Lance has "contamination" in quotes; perhaps he doesn't
believe it's a real issue in brewing? In that case, it would be
difficult to explain why so many commercial breweries (small and large)
spend a huge percentage of their time santizing.
As Al Korzonas pointed out elsewhere, the human mouth is a rich source
of bacteria, and the point is to reduce any possibility of contamination
(no quotes, Lance). People who persist in starting siphons this way are
like the happy idiots who continue to smoke -- they're not dead yet,
but...

The Munich breweries have a leg up on you, Spencer. They have the
perfect source of water for malty beers. Adjust your water accordingly,
use Ireks Munich malts, keep the saccharification temperature up,
bittering units down and, voila! malty beers every time.

Subject: RE: PUMPS
A recent article here suggested using peristaltic (tubing) pumps for
homebrewery use. While I fully agree that they are the ultimate where
contamination control and ease of cleaning are concerned (and of course
for precise metering of delivered volumes - their primary application),
their flow rates are too low for many (most?) homebrew operations. My
preference is for magnetic drive pumps, which combine excellent
contamination control and ease of cleaning with flow rates 10-100 times
greater than typical peristaltic pumps. Essentially, these are small
centrifugal type pumps, where the drive shaft has been replaced by a pair
of magnets: one on the motor and one on the pump impeller. This
magnetic coupling eliminates the need for the pump shaft seal and
potential contamination problems from seal materials and lubricants.
Pump materials are available that are highly resistant to chemicals and
temperatures and that are rated for food grade applications (NSF rated).
Personally, I've used two of them: Little Giant MD-4 and the Gorman Rupp
Industries model 14110. While list prices on these units typically run from
$120 to $300, I was able to find an unused, surplus, version of the GRI
unit for $59.95 (Surplus Center, Lincoln, NE, 1-800-488-3407. Catalog
#2-1073). This unit is rated by GRI at 8 gallons per minute (480 gallons
per hour) @ 5' head pressure (difference between inlet and outlet
elevations). Maximum temperature is 203F. It's made of Ryton with
stainless steel, teflon and a couple of ceramic materials used for
bearings. Connections are standard threaded pipe fittings. While not
specifically listed as food grade, the materials are identical with other
food grade pumps. Cleaning is easy; just circulate your cleaning
solution for a minute or so. It's also easy to open for cleaning - a
clamp ring holds the pump body halves together. Pump is speed
control-able by any common motor speed control. I use a ceiling fan
control that cost about $8.00. You can also throttle the flow by
installing a valve in-line with the DISCHARGE side of the pump (NEVER
restrict the inlet/suction side of ANY pump; it can damage the pump).
Size is about 8" x 5", making it easily portable (I'm planning on using
it as a CIP [clean-in-place] pump) in addition to using it for mash
recirculation and wort pumping. A final note regarding temperature
ratings: while the mfg rates the pump at 203F, I've had no problems with
boiling wort (probably closer to 215F) other than bubbles in the suction
line, due to the hot wort flashing into steam from the reduced pressure.
To avoid this, place the pump at least 2' below the vessels being
pumped (the column of liquid above the pump maintains a positive
pressure). Also, even the Little Giant pump, mentioned abouve, nominally
rated at 150F has worked fine up to about 200F.

Subject: Fermentation Vessel Variations--a new idea
To the collective HBD brain.
Has anyone thought about using an *inverted* soda-keg for a fermenter?
I've been thinking a lot lately about about the way I brew. Usually I quit
during the summer months, but this year I thought I might continue, and so
I've been looking for ways to reduce the risk of wild yeast contamination.
I don't brew any lagers, and normally I do a single stage fermentation in a
7gal carboy. I had been trying to decide between the brewcap(tm) inverted
carboy technique, and the soda keg - closed fermentation system, as described
in the gadgets special issue of Zymurgy.
It boiled down to this: I like the idea of being to remove the trub, yeast,
and beer (at different times) without racking, which would be a vote for the
brewcap. On the other hand, I like the completely sealed transfers of the
soda-keg technique.
That's when I got to thinking about inverting the soda-keg, using the dip
tube as a ventilation shaft (for want of a better term) and using the gas-in
as the trub, yeast, beer exit.
Alternatively, I suppose one could remove the pressure releaf valve and
install a ball valve there to remove trub. The only problem would be if the
dip tube gets blocked (it is very narrow after all) then you've got a *big*
grenade on your hands. Infact a ball valve could probably be installed in
the lid, next to the pressure relief valve.
I think this would necessitate a smaller batch size--possibly 4 gal, and of
course I'd no longer be able to see my beer brewing :-(
On the plus side, I wouldn't need to shorten the dip tube for fermentation,
so the same keg could be used for dispencing with another batch.
Has anyone ever tried this? Has anyone ever given this any thought??
I'd love to hear all your comments, questions, and ideas. Private e-mail is
welcome.

Subject: Refractometers
On a recent business trip to Detroit, I followed up a tip
from one of my surplus scientific equipment scrounging
sources and found an awesome source near downtown. (Great
story about the place; e-mail me if you wanna hear
it.) Bottom line -- scored a brand new hand-held
refractometer for a fraction of the market price.
My question -- does anyone know what the formula is to
convert the refractometer units (Brix %) to specific gravity
or degrees Plato?
