I forget exactly what I said in my post but what I meant was that Ecolab's
"Iodophor II Sanitizing Udderwash" which Agway sells is not FDA approved. I
know some people are currently using this. I talked with a rep at the St.
Paul,MN office who told me which products are o.k. and which aren't. My notes
don't say whether the Mikroclean is FDA approved but if that's what the label
reads it must be. As I stated however, it was the reps opinion that I should
use the "Diophor" product. It sounds as if they make many similar products
of which more than one are probably o.k. to use. Sorry if there was any
confusion.
Someone also sent me a message telling me about a product called Proclean 200
found in restaurant supply shops. It sells for $22/gal.
I rinse the iodophors despite the claim that it is not necessary. These
agents are powerful enough where they could effect yeast growth if they do
not fully evaporate.

Subject: Wort oxygenation
I brew in 10 gallon quanitities and do my first stage in a modified 10
gallon Cornelius-type keg. My kettle is a modified half-barrel keg with a
stainless nipple on the bottom and a large hole cut in the top. My wort is
chilled (possibly too much) in a countercurrent heat exchanger I made from
copper tubing and rubber hose.
Since I switched from fermenting in carboys to this stainless steel
unit, I've noticed that fermentation has been less vigorous. When full,
the fermenter is heavy and I can't really pitch the wort to oxygenate it
(not that I ever did this to great extent when I used carboys). My
hypotheses regarding reduced fermentation activity center around too
little oxygenation or too much cooling. Since I never had this problem
with carboys, I figure it is the oxygen.
I have access to an oxygen tank and have been considering the following
solutions.
1. Low tech: Drill holes in the end of the chiller an inch from the
outlet so that air is sucked in (courtesy of Venturi). Potential problem
is foaming wort, preventing me from maximizing quantity. Plus is that I
don't have to beg my boss to let me have the oxygen tank for the weekend.
2. High tech #1: Add a pipe fitting that allows oxygen to be added to
the hot wort as it enters the chiller. Plus is that cooling of the oxygen
wort mixture would reduce foaming (I think) and turbulent flow through
chiller would maximize oxygen-wort interface surface area. Potential
badness is that oxygen tank would be close to burner and probably
wouldn't explode, but you never know.
3. High tech #2: Stainless steel pipe to immerse in kettle and blow
oxygen in. Disadvantage: solubility of oxygen in hot wort is lower at
higher temperatures (probably insignificant). Advantage: simple, low
cost, no foaming.
4. High tech #3: Seal primary fermenter and drive oxygen into wort
under pressure. After a few hours, stop, bleed off pressure, and attach
air lock. Advantage: eliminates the foam issue. Disadvantage: yeast could
go nuts, overpressurize the keg, and I die in a bizarre brewing accident.
Anyone have experience with this? I favor solution three. Has anyone had
success with oxygenating wort that has just been boiling? Do any Jedi
masters of chemistry know how much the oxygen solubility changes between
65F and 212F ?

Subject: advanced homebrew seminar
In HBD 1640 Dudley Leaphart shared his opinion that the American
Brewer Guild's Advanced Homebrewing Seminar was essentially a waste
of time for anyone beyond the beginning all grain level. Having just
sent them $99 for one day of a two day seminar coming to Boston on March
18-19, I immediately panicked and called the ABG headquarters in Cal.
I was advised to speak with Bruce Winner, the president. He was
unavailable at that time but gave me the consideration of returning my
call, even tho I said I would call him tomorrow.In his opinion, this
course would deffinitely be informative for someone who's been all grain
brewing for less that two years, such as myself. He invited me to talk
to the seminar instructor, Ashton Lewis, and if I still felt the seminar
had nothing to offer me, they would refund me my check.I thought this to
be fair, and was impressed at the quick attention given me. I'm going to
attend this seminar based on Mr. Winner's recommendation. I offer this
to you in hopes it may be of help.

Subject: Removing lather due to aeration
Last night I had to shake a half-full carboy to aerate the wort. When I
was done, a lather about 1 foot thick had formed. This created a problem
with getting the rest of the water into the carboy. To make a long story
short, I did the following: filled the carboy as high as I could with
boiled-then-cooled water, put a solid stopper in the mouth of the
carboy, put the carboy in the kitchen sink, and used the sprayer to gently
spray hot water onto the carboy were the airspace was in the carboy. This
increased the air pressure in the carboy, which forced down the lather!
Some notes:
1. The termperature of the wort was not elevated by a noticable amount.
The carboy was in a stainless steel sink that acted as a heat sink.
2. Every so often I removed the stopper and added more water to
decrease the airspace. I found that it was best to heat one small spot
first, then spread out.
3. I had to be careful that the carboy did not block the drain. At one
point I noticed that the carboy was sitting in a pool of hot water
because of this.

****** from Bruce DeBolt *********
Pardon the bandwidth.
I'll be Walnut Creek, CA next week and am looking for a place to buy
Deschutes Brewery's (Bend, OR) Black Butte Porter and Bachelor Bitter. I've
called the brewery but they go through a distributor and I had no luck with
that call for details. I looked in a few places last time I was in CA (no
luck), hence the post. I'll have a car so can drive anywhere in the Bay
area. Private reply please.
I'll re-ask a question from earlier this week. Looking for experiences of
HBD brewers on using lots of crystal in a predominately pale malt batch,
i.e. 2-3 lbs of crystal in a grist with about 8 lbs pale 2-row. Haven't
found any information on this in my available sources. Private reply also.

I've seen several references to George Fix's notes on a 40-60-70 mash
in HBD. I obviously missed the original post and can't now locate it.
Can someone post the HBD-number or zap me a copy--dweller@gvsu.edu. On
the subject, is there a way for us cyber-impaired to search the sierra
archives (I don't think I have any built-in software to do it).
Another subject: I love lagers & pilseners but brew only ales, because
of equipment, space, facility limitations, and that's not likely to
change. Is there anything published, or do any of you list gurus have
some good ideas, on how to replicate a nice German lager with an ale
receipe and ale yeast?

I am aware of 4 different professional references which cite 4 different
temperatures for malt gelatinization. I have not done direct measurements
of the carbohydrate spectrum at the various stages of the mash (this
would make a neat Masters thesis for someone with an access to a HPLC!),
but it my feeling that gelantinization starts at much lower temperatures
than 65C (149F), but probably is not complete until the temperatures
reach the mid-60s. Nevertheless, I have found there is significant
beta-amalase activity and concurrent maltose production at 60C (140F).
In fact, varing the time taken at 60C is the best scheme known to me
for varing wort fermentability.
The fermentability that is actually achieved depends a lot of other
factors other than wort fermentability. These include yeast strain,
yeast viability, wort aeration, fermenter geometry, et al. (Bob Jones
discussed some of these issue at the National Conference in Denver).
The best way known to me for identifying the contribution from wort
fermentability is by a forced fermentation test (FFT - not to be confused
with the Fast Fourier Transform!). Remove a ~liter of chilled wort, aerate
it, and pitch with 2-3 times the normal concentration of yeast (say,
50-60 million cells per ml.). Hold the temperature at 25 C (77F),
and within 72-96 hrs. all the fermentables should be metabolized. The
final gravity from the FFT will likely be a tad lower than what is
achieved in the main batch, but the two should not differ by much.
What I like about a FFT is that it gives us a handle on wort fermentability
as well as info on how well we are doing with wort aeration and yeast
management.

Subject: Fat Tire, AOB
I wanted to clear up any potential misinformation in Roger Grow's post
about Fat Tire Ale (have to stick up for the hometown breweries).
First of all New Belgium is in Fort Collins, Colorado, not Lakewood.
New Belgium Brewing makes Fat Tire, an amber ale, Sunshine Wheat, a
wheat beer obviously, and several Trappist ales: Abbey, a single,
Trippel, and an occasional Grand Cru. Roger mentions "that Fat Tire
wheat taste", but I'm not so sure Fat Tire does contain any wheat. I'll
see if Jeff Lebesch will tell me next time I bump into him.
The second recipe says to use "#1214 Belgum Ale" or "culture from
several bottles of Fat Tire Belgium Ale". Well, there's no such thing
as "Fat Tire Belgium Ale". The recipe looks more like an amber ale than
a trappist single, but it's not clear to me which one they're trying to
emulate. Needless to say, the recipe as is might be tasty, but won't
approximate anything that New Belgium brews. The folks who do the Rocky
Mountain Homebrew newletter had better be more careful about their
sources.
Okay, on to something that might interest more than three people. Lee
Bussy asks about email address for the Association of Brewers (AOB).
I recently received an informational mailing from someone I know who

Gelatinization is only required for UNMALTED barley, as well as other

Subject: Dave's bar/ recipe request/ RIMS
Warning: I have never kegged in my life. Having said that, it seems like Dave
could always have cold beer out of his tap if he had one of those cold
plates people stick inn their fridge. The beer still in the line coming
up from the basement would be warm, and a cold plate cold handle chilling
it, and by the time the cold plate was done in (they're only good for a few
beers at one time), cold beer from the keg would be on its way up, and
wouldn't need chilling. Just a thought.
A friend asked if I could post a recipe request. He wants a reasnoably dark
(read: flavourful) ale. Kind of along the lines of a Smithwicks, but with
less bitterness, yet more hop flavour. I guess that would invole later
additions of a fair amount of hops. Malt extract only. TIA
Finally, a truly different request: I want to make a RIMS setup that is
more complicated than it need be. More complicated in what way? Doesn't
matter, as long as it works. WHY??? I'm taking a graduate course in
microprocessor interfacing techniques. My final project is to build anything
I want, that involves some reasonable level of computer interfacing. My first
thought: an automated beermaker! But a RIMS setup doesn't need terribly
much control. The software end would only require temperature control, a
pump, and maybe some valves. The prof wants some reasonably complicated
programming to happen, so the RIMS seems too basic. RIMS builders feel free
to correct me on this point. With a RIMS the hardware side would be truly
challenging, but won't be worth many marks. One further complication: I don't
have a computer, and don't want to spend tons of money on this project. I
figure grab an obsolete 8086 from somewhere, and hopefully only fork out
<$200 (preferably <$100) for it and the kettles, tubing, pump, etc. Does
anyone think this to be even remotely possible? Please?

I am having a problem with my orginal gravity being lower than what the recipe

crystal malt and carapils than the recipe called for. I steeped the grains for
about 30 min between 150 and 170 degrees. Then added the extract and boiled for
75 minutes. My brewing is extract based with specialty grains added. The beer
tastes good, however, I am curious about the variation in gravity. What am I

Subject: Hop Utilization
I am going through the process of trying to calculate IBU values, and
have read the formulas by Rager in the 1990 special issue of Zymurgy, as
well as the book "Using Hops" by Mark Garetz. After some
experimentation, it seems the biggest affect on calculated IBU levels is
the %utilization value, despite all the other correction factors
discussed in the Garetz book. Unfortunately, these two sources differ
widely, and I recall some discussion as to the appropriate utilization
values being different from both sources. Does anyone have any wisdom
to share on appropriate values to use for the %utilization for different
boil times? If this subject has been beat to death sometime in the last

Per Dave Miller in Brewing Techniques Jan/Feb 1995, he states that ATC pH

According to a representative at Corning Inc this is not true and in fact
ATC will give you a reading at the temperature of the sample. The tech.
representative I spoke to insists ATC does not adjust the reading to
reflect that sample at room temperature. Also a pH conversion chart to
compensate for temperature can be found on bottles of Corning (and
probably other) buffer solutions. Any comments on this issue would be

If this is true, than what happens if the nasties get the first
crack at the wort? In other words, is it possible that a dangerous
organism could get started in the wort before the yeast does and keep
the yeast from getting a foothold? If this happened, then there wouldn't
be lowering Ph and there wouldn't be alcohol to kill nasties.

Subject: SUDS 3.1 v 3.0c IBUs
Dear Friends, Chuck M. commented on the Garetz-based IBU routine in SUDS v
3.1, by Michael Taylor. I have been on about this since the day it was
uploaded to the archives, and after a fairly extensive effort in
collecting data, have contributed to Mike's decision to allow the user to
choose which set of utilization data to use in making IBU calcs. This
option will be included in subsequent releases. I will be collecting the
utilization data for him and will send it along in a couple of days.
This past weekend, while Domenick Venezia was visiting, he, Andy Walsh,
Ken Willing, Chris Pittock, and myself had a beer 'n' dinner 'n' beer
evening at Kens's place, and several of Ken's beers had been made using
the 3.1 formulations, and were conclusively identified to be way
overbittered (no one knew until days later that 3.1 had been used). I
have heard from many others via email and r.c.b. on this, and no one has
supported the Garetz-based formulations. So: use 3.0c until the next
version is released.

Subject: BBC hops/another use for steam
Brewers,
The day I posted my question about what ever happened to the
Boston Beer Co hop offer, I received a calendar from BBC
with their address and phone on the first page. Cool daily
calendar with a beer quote or trivia for each day of the
year. They can be had free of charge by writing BBC at The
Brewery, 30 Germania St., Boston, MA 02130 or call 617 522-
3400. Say what you will about Jim Koch and his business
practices, they make a decent beer and if you can overlook
the blatant commercialism of their freebees, they are nice.
Anyway, as for the hops, they are still available.
According to the person answering the phone at BBC, they are
waiting for a large enough number of orders to make a bulk
mailing. One pound of Mittlefreuh hops (pellets I think) for
$12. Send a check to the above address. My thanks to those
of you who answered my post. Hope this answers any
questions.
On another note, I've noticed a lot of talk about steam
lately. I have another use for steam that was suggested by
a member of my local brew club. I've been using it for a
few years now with no ill effects. I use steam to clean my
kegs. I picked up a tea pot at a second hand store for 25
cents. Take a drilled rubber stopper (#8 I think) and
insert a short piece of copper tubing (4"). Now attach a 4-
6' piece of hose to the copper tube and a liquid disconnect
on the other end. Now simply insert the stopper in the tea
pot and connect the liquid disconnect to the keg. Make sure
you attach a gas disconnect to the other side of the keg to
vent out the steam. Put some water in your tea pot and
boil. The steam will sanitize the kegs and poppets in 15-20
minutes. Make sure your system is open or the pressure will
build up and blow your stopper across the room in no time.
Takes an hour or two to cool and you will want to drain the
condensation from the keg. I've never had a contamination
problem using this method. YMMV All disclaimers apply.
Brew On,

The AOB had a DNS (Domain Name Server) problem (our Internet access

it should be working now.
Likewise all info@aob.org and other messages to aob.org will have bounced,

Since I'm writing this anyway, I'd like to mention that we have a new web

have fun,

Subject: Competitions
Someone mentioned a bias toward all-grain vs. extract brewing in AHA sanctioned
competitions. I'm going to stick my neck out here 'cause its not exactly my
department, but I was under the impression (IMHO) that AHA competitions were
"blind" with the judges knowing neither the brewer's name or the recipe used.
Like I said, this is my opinion and I'm not 100% positive (or even 25% sure),
so this isn't a guarantee or anything.

I'm replying to the list because I suspect Ron and I aren't the only ones in
this fix. I'm in the same boat, with the added complication that I'm attempting
to close out the bank account the check is written on. The BBC number is
617-482-1332. The person you want to talk to is Lucy Sholley. She was very
pleasant, and referred me to their mail fulfillment company. The person there
told me that they (the fulfillment house) have nothing to do with any checks.
BBC just sends them the names and they mail out the hops. She did promise to
talk to Lucy and get back to me, and to send out my hops in the meantime. This
all happened today before I got HBD, so I don't have a final resolution yet.
I'll post when I see my hops and/or my check.

Good day Brewers and Brewsters!
I am a new subscriber (Yes, I just recieved my third issue), I am glad to
know such a group is available to us as brewers to talk about the wonderful
substance called Beer. I want to reply to a couple of things I've seen so far
this week.
Re: Pictures of All Grain Brewing.
The catolog from Hoptech has an excellent picture of their sparging
system. Call them at 1-800-DRY-HOPS. I also consider them a Bible of info on
Dry-Hopping.
Re: A-B's Use Of Non-reuseable Bottles.
Just one more reason to not drink any of Budmillercoors' products.
One other poor excuse for bottles is clear Miller Genuine Draft bottles. A
buddy of mine used some once and broke about 6 of them just during the capping,
and about that many after a week in the bottles...
Re: Coffee Beer.
I tried a coffee porter once and had bad luck. This may be because I
put the ground coffee in the primary fermenter, or it may be because I used
too much coffee (1/4 pound!). The beer smelled like tomatoe vines (Yuck!).
Keep us updated on the status of your brew, and the technique used. I would
like to try again someday.
Now for a Question: Does anyone out there have any good clip-art of Hops?
I am a real big Hop-head and want to use it on letter heads, etc.
If you do and it is on-line somewhere, Please either send it to me, or tell me
where to send to to get it.
Happy Brewing, everybody!

In HBD 1641, Al K. said:

Since the Ann Arbor municipal water supply now uses monochloroamine to
chlorinate its water, and this is essentially not removable by boiling
(you have to use an activated charcoal filter), I thought I'd check to see
how common this is. I spoke to Larry Sanford, the water chemist at the AA
water treatment plant. He said that AA is probably the only plant in the
state to use this, and he guesses that only about 15% of plants in the US
do. I asked if it were required by federal regulations, and he said no,
that they require only that a disinfectant be present in effective levels
to the consumer's tap, and that this is the best method. It isn't new,
either. Denver has been using it for 70 years. Ozone is used only
the treatment plant; it doesn't last long enough to be effective in
the mains.
This has been the topic of some speculation in the past, including by me,
and I hope this helps. If in doubt, phone your water treatment plant.

Subject: Vacuum vs Pressure Siphoning
Hi All,
I'm a long-time lurker, first-time poster. I really think this forum is a
gas! I've incorporated many tips/techniques that I've read here to my own
process, so, after reading Dave Miller's column in the latest BT (vol. 5,
#1) about the dangers of starting a siphon with pressure, I thought I'd share
my method for vacuum siphoning. I know I'm not the first to think of this,
but if it saves someone's life (or a precious batch of brew), than it's
probably worth me breaking out of lurk.
All that's needed is one of those orange carboy caps (you may have to try a
few - some don't really fit tightly), a piece of 3/8" I.D. Tygon about 3
feet long (for applying the suction necessary to create a vacuum in the
carboy), and a short piece (6" or so) of plastic racking cane (or copper
tubing the same size) with several small "carburetor" holes drilled in it,
for racking from the kettle and aerating the wort. If racking from primary,
you'll need a longer piece (without holes, of course) that will reach to the
bottom of the carboy to minimize splashing.
Clean and sanitize the receiving carboy (and purge with carbon dioxide, if
racking from primary) and the other above pieces, stick the piece of cane
through the large center hole on the cap (leaving an inch or so sticking out
of the top of the cap), attach the 'vacuum' Tygon to the stem part of the
cap, and snap the cap onto the carboy. Attach a whole racking cane to one
end of a longer piece of Tygon (a regular racking set-up) and stick the the
other end of the 'racking' Tygon onto the end of the cane sticking out of the
center hole on the carboy cap.
Now, all you have to do is hold/suspend the end of the racking cane in the
kettle/primary, and suck on the end of the 'vacuum' Tygon with one good,
strong pull (use your mouth and cheeks more than your lungs and don't let it
pull air back into the carboy from your mouth - practice with water first).
You'll probably be surprised at how little effort is really needed to get a
flow going. I find that if I pinch or bend the 'racking' Tygon slightly
near its attachment to the racking cane, the bubble that forms there will go
away.
You'll observe that, once beer starts flowing, there will be a positive air
flow 'out' of the Tygon that you sucked. Unless you let the vacuum in the
carboy pull air out of your mouth while sucking, instead of beer into the
other end, I believe you won't expose the beer to any potential
contamination - at least, I've never experienced any.
This description took far longer than the above procedure and probably reads
as a pretty complicated technique, but it's really quite easy. I hope that
the majority of the HBD readership feel that this was worth the length
(whew!) and if I am wrong about the possibilty of contamination, someone
please tell me!
Thank Ninkasi for the HBD!

Lee, I would suggest force carbonating by gentle agitation, and
then putting it in the fridge. The foam will subside overnight,
and within a week the cold break will have settled. Perfectly
carbonated, crystal clear beer...
Use your pressure/temperature/volume chart to determine what you
need to achieve the correct carbonation level. Example: my
cellar temp is 60^ F. and I want 2.5 volumes of CO2. I purge the
keg and rack the well settled (or preferably fined) beer over.
Per the chart, I need approximately 23 psi. Pressurize your CO2
line and attach it to the keg. Sit on a chair with the keg
across your lap, gas side up. Alternately raise one knee then
the other for 10 minutes (in tune with, say, _American_Pie_ -
avoid heavy metal!). That's it - you beer is now carbonated.
Here is the chart:

Beers to be dispensed from the keg should be
carbonated to between 2.0 and 2.5 volumes, depending on
style. Beers that you intend to carbonate in the keg
for counterpressure bottling should be carbonated to a
higher level, 2.5 up to as much as 3.0 volumes,
depending on style.

I would like to hear some opinions about dry hopping...specifically what
are your preferences between:
1) dry hopping in a secondary for a few weeks and THEN put into a keg
or
2) rack from secondary into a keg and throw a weighted hop bag into
the keg and seal...
