Subject: Millennium and mead!
Befor I get into the main part of my post, I am finally caught up with
the HBD and thus qualified to post again after many months. Not
wanting to sound more ignorant than I am.
In answer to the post about the stuck mead, I notice that he said he
had 15lbs of honey in a 5 gal. batch and ended up with an OG of
1.145-150. This seems a little high to me. He would have gotten about
50 points of gravity from each pound of honey. I wonder about
measurement here. That sweet mead yeast is not a great fermenter of
low nutrient musts. On the Mead lovers digest I have read about a lot
of stuck fermentations with it. I don't think your experience is that
much off the usual for that yeast getting about an 80 point gravity
drop on a low nutrient must seems about right(ABV of 10%?). I do
wonder about the gravity readings. Either the weight of honey , the
volume of the must, or the gravity readings you have seem to be off. I
have taken to using Lalvin yeasts. Lots of beer brewers denigrate
dried yeasts, but many mead and wine makers find the dried products
more than adequate for our needs. I am also using Lalvin D-47 for
cider this year.
I lend my support to those that realize that the Millennium is not yet
upon us (good for us procrastinators). On the other hand the meeting
in Detroit might be a good warm up. When do we start planning the

Subject: First Wort Hopping
I've used First Wort Hopping on my IPA. It provides some spectacular hop
flavor, way better than any other method I have tried. Here's the recipe, for
those of you who care:
Lion Fan in Packerland Extremely Bitter IPA
(assumes 70% mash efficiency)
12# Pale Ale malt
.5# 40L Crystal
.5# Victory malt
.5# Carapils malt
2 oz Galena (12% AA--60 minutes)
2 oz Cascade (3.5% AA--1 oz FWH, 1 oz dry hop)
2 oz Northern Brewer (8.5% AA--.5 oz FWH, .5 oz--10 minutes, 1 oz dry hop)
Your favorite English ale yeast (I prefer Whitbread aka Wyeast #1098)
It's the closest I've come to the "wall of hops" beer. Very tasty, IMO. I've
also used Columbus in the place of Galena.
My big question is this: How do people calculate the bitterness contributed
from the first-wort hops? Based on the article Jeff R. quoted, I've always
calculated them as if they were added with 20 minutes left in the boil. I've
seen others who say that you should figure a _greater_ bitterness contribution
than if you added them at the start of the boil!
Obviously, it doesn't matter much with this recipe. The more bitterness with an
IPA, the merrier! But I want to try my hand at a pilsner again this winter.
Such a delicate beer could be thrown way out of whack by over-bittering.
Thoughts? Hearsay? Innuendo?
Thanks!

Subject: BT back issues
As a Canadian who is long used to sucking at the hind tit when receiving US
periodicals I am obliged to point out that I have in my hot little hand the
back issues from BT in lieu of cash payout.
I also note that Stephen Mallory has posted a credible explanation for the
delay in mailing out the balance of back issues.
I for one will not re-subscribe to Zymurgy. As a matter of fact I gave away
4 years of Zymurgy to a neophyte home-brewer. Which is where that magazine
appears to be happiest - i.e. with the beginner.
But I am quite willing to support a brewing magazine that straddles the
line between serious amateurs and small-scale commercial breweries. I may
never get around to starting my own brewery but this must be one of the few
hobbies that the amateur has a real shot at turning pro.
Dream on,

Subject: A new method of support for the Digest...
Greetings, Beerlings! Take me to your lager...
Folks, usually at this time I go begging for donations for some server
project or other. This year, we're in good shape - mostly because of all
the help you gave us back in September when the server did a major
crash-and-burn. We have a new, bigger, faster box for the HBD, plus another
(believe it or not: the original "Frankenserver" that was constructed when
we took over the Digest three years ago!) online right alongside it to aid
in future calamities. We also have one humming alongside me (the one that
died such a horrible death back in September) which I am preparing to do a
complete mirror of the main server. And to bone up on my Linux skills.
Our goal this time out is to try and find a "renewable", constant means of
support for the Digest servers. If we are able to, and the levels are high
enough, we hope to bring the servers "home" on a DSL line. This will help
in those instances where we reset the box, and she never comes back online
- like a couple of weekends ago (blush). Unfortunately, the times I usually
think to do such things are the least convenient in terms of when the staff
at O&E are available to help (There is a method to my madness: it's usually
Saturday night or Sunday evening. Sunday is a Digest-less day, anyway...).
Anywho, we have stumbled upon this thing called "AllAdvantage" which,
frankly, pays us to surf the net. Karl and I have both signed on with our
receipts for participation funding the server. Karl referred me, so he gets
paid for every minute I spend online, as well as every minute HE spends
online. If I refer you, I'll get paid for every minute you spend online (so
will you, and so does Karl). Anyone you refer, they get paid, you get paid,
and I get paid. Kind of a no-pain MLM. There is a catch, though. There is a
"bar" that lives in the bottom inch or so of my monitor. This bar gives me
access to my AllAdvantage account, and gives them access to me. Frankly,
they SPAM the living hell out of me by pumping adds into their viewbar.
I've gotten used to it. And I've even "clicked through" a few times as the
items/services displayed were of interest. The point being, they'll pay you
for being on the web, and they'll pay me (thus, the HBD) for you being on
the web, and they'll pay Karl (and thus the HBD) for you being on the web.
Or on AOL, or writing a note in Netscape...
If you'd like to participate in this, stop by
http://hbd.org/alladvantage.html and it will tell you how to join the
effort. We'd all appreciate your help. If not, please pardon this brief
intrusion into your daily dose of the Digest!

Subject: Benzene, Odd Day, and Dr. Pepper Stout
Hi, Ya'll
The comments by Frank Timmons (HBD#3177) about CO2 are seconded by
another industrial chemist (me). What he said is correct. When you
have spent the last 3 months grilling suppliers about contaminants at
the ppb level in delivered CO2 and NH3 for pharmaceutical applications,
benzene is TRULY infinitesimal.
Also, thank you Dave Burley for the diatribe (HBD#3177) concerning the
fallacy of benzene toxicity in human subjects. My former organic
professor washed his hands in copious amonts of benzene to remove the
stench of trace thiols and mercaptans for 30 years before deciding to
teach. He is retired now happily, cancer-free, at 80+ years old. Some
studies have shown that Benzene derivatives are powerful intercalating
agents on human DNA, but none of these studies have been done in vitro,
and none implicate simple benzene (Kekule would be happy).
By the way, I think Dave has performed a test on the Collective with his
Odd Day Proclamation to see who was paying attention. Or maybe he was
getting a bit chilly in November and decided to get some flame action
happening just to keep warm.
For those of you out there thinking of doing a mint stout, I suggest
that you ONLY use peppermint as opposed to spearmint. I made a 5 gallon
batch of stout and used a bunch of spearmint from my yard to flavor it.
I called it 4 Nines Mint Chocolate Stout because I brewed it on 9/9/99.
What I got was a very dark stout from a high malt bill that tastes
exactly like I poured Dr. Pepper into a perfectly good stout. My wife
says it tastes like medicine( but what does she know, she likes Rolling
Rock). After two or three decent homebrews, it is drinkable, with a
creamy vigorous head. Luckily I like Dr. Pepper. I'm hoping a couple
of months will help, but I doubt it. At least I'm willing to drink it,
but I learned a lesson. I'll try to follow the recipe in the future (it
did specify Peppermint, but I ignored that).
As to Alan Meeker's contemplation about writing a comprehensive book on
the use of yeast in brewing...I'll buy the first copy. Your advice
about pitching a LOT of yeast has improved my last couple of efforts
tremendously (not including the mint stout-my bad). I'm almost at the
point where I can intelligently make use of more detailed information.
Write the book!
I plan on celebrating New Year's with several good homebrews, but at
midnight I crack open my little blue bottle of Samuel Adams Triple Bock
from 1995. The tag on the bottle requests that I send my comments to
the brewmaster, because they have no idea how it'll turn out. Can't
wait.

I'm not really surprised that this article has not generated much
discussion.
I am a wee bit in awe of anyone who can casually talk of homemalting in
terms of tons.
However, same view from a different angle.
Love the idea of a climate controlled germination room.
In my experience the only difference between undermodified and fully
modified is time. As the grain grows it is using its stored water with no
replenishment and the rate of growth slows down.
With my system I can get 50 percent modified grain in 3 days in the
germination box.
To get the next 30 percent takes 3 more days.
With my steeping process, apart from an initial 4hr soak, the grain is never
left totally immersed in water for more than 5 minutes. The grain gets
covered with fresh water, stirred to float of the debris, and then drained.
The moist grain soaks up the available water and stays a lot healthier than
with continuous steeping. More in line with what the seed gets in natural
conditions. This gets repeated every few hours (or when I remember). The
first rootlets start to emerge at about 30hrs when it is given a final
drink and then into the germination box.
In 'The Historical Companion to House-Brewing' by Clive La Pensee he
recommends that the germination cycle of the grain be kept in the dark. He
says it is something to do with photosynthesis, which doesn't make much
sense to me, but it is closer to the natural germination conditions that the
seed is expecting so I do it. It just seems to keep the synchrony of the
germination at a fairly close level.
He also recommends keeping it in the dark for drying and storage.
I have come to prefer my home malted pale malts for flavour to the
commercially available product (Moray Firth). Haven't been able to get the
Munich types right yet.
The only real problem is that with every variation I try, the only way to
find out if it works or not is to brew another beer with it. You really need
to be dedicated to keep going, but I'm working at it.

Subject: Question on Welding Aluminum
Hi folks,
I'm posting this for a friend who doesn't have time to scan for answers.
But actually it applies to me as well, since I'm looking for the same thing.
Here's what he wrote :
First question, is: are there any rods that should not be
used to do this if it will be in contact with the wort, i.e.
what should be used?
Next question, I will be using a stainless steel ball valve
screwed on there. Does this pose a problem for galvanic
corrosion since the threads will not necessarily be fully
dried of wort between uses or does a little teflon tape
suffice? Should I be unscrewing it every time (or maybe
just at the end of the season for my summer hiatus), and
if so, will the aluminum hold up?
thanks,

I can't say for sure, but I'll bet that the people at BT are probably not
getting much pay for the work they are doing to provide back issues. The
head guy has already taken a different job at a different magazine. MY
experience with the rag is that it warms my heart every time I think of it.
Name another magazine that was closer to the real brewing community. Or
another that was willing to accept and publish articles from brewers at
large rather than just their "chosen few." Or another that cared more about
the technology rather than sales figures from publishing cheap
attention-getting articles that repeat the same drivel over and over again
because they tend to increase sales from non-serious curious onlookers at
the local magazine stand: "Can you boil water! You can make beer!" or "Make
your favorite beer cheaper than you can buy it!" etc. I give BT my
perpetual thumbs-up and figure waiting on a back issue or two is no big deal
... how fast would you fill orders _after_ losing your job? And BTW, before
anyone makes accusations about botched finances or mismanagement and what
not, I'd back it up with facts or don't bother. The good people at BT don't
need the noise.

There are several reasons for prefering such wheat in my mind. Soft wheat
is soft because of their protein - it is less glutenous (bad for bread,
good for cookies, biscuits, pie crusts, etc), which makes it, I feel,
better for brewing, also - less chance of a stuck mash. It are also easier
to mill soft wheat. Furthermore, soft wheat is typically lower in protein,
and since this is good in malting barleys, I think it must also be good in
wheat. White wheat has white bran as opposed to red. A quirk of wheat
genetics is that the gene for bran color is linked to the gene for bran
tannins and phenols, so white wheat is milder in flavor than red. (I
understand that Nabisco uses almost entirely white wheat in shredded wheat
becuase of this). Now I don't know if all of this or even any of this is
important, but I feel than my wits have a nicer character with soft white
winter wheat than with hard red. This is what Hoegarten uses in Belgium,
but when Hoegarten founder Peter Celis came to the us (Texas) and started
his brewery, he used Texas hard red winter wheat. Go figure. I think it
must be a matter of using local produce. texas hard wheat is lower in
protein and less glutenous than high plains hard spring wheat, however,
which is what is used to a high extent in bread flour.
I have no idea of the availability of any of these kinds of wheat in
Australia. It seems to me it's all hard red.

Dave, it's either one or the other. You can't write
a scientific treatise and rant at the same time.
As a health & safety professional, I share your dislike of
extremist, sensationalist rants about "toxic chemicals".
However, non-specific dismissal of the hazards of materials
is at least as sensationalist and probably more irresponsible.
I've followed your posts in the past with great interest (your
knowledge of brewing and brewing chemistry is impressive),
and this is not your style.
Sorry for the rant. Here's the data. It was extracted from
Sax's Dangerous Properties of Industrial Materials.
CARCINOGENICITY?
>Unless I missed something, it has been only
>proven so in specially selected, tumor
>susceptible mice. But, he is right it is
>*legally* a carcinogen
I guess you must have. (Unless you use the tobacco industry
definition of "proven".) All national and international scientific
authorities have labeled benzene as a confirmed human
carcinogen or "sufficient evidence" human carcinogen This
includes the US National Toxicology Program and the
International Agency for Research on Carcinogens These
are scientists, not politicians. They reach their conclusions
only after reviewing all available research and subjecting their
whole process to peer review. The result is a consensus of
the scientific community. According to them, Long term
chronic inhalation exposure to benzene has been clearly
linked to lymphomas, myeloid leukemia and Hodgkin's
disease. This is the most serious health hazard benzene
poses. Not that a single exposure should be feared, or
even multiple low-concentration exposures. (heck, every time
you fill your car with gas you get some minor exposure.)
But anyone using benzene should do so in a well ventilated
area and minimize the vapors he/she breaths.
TOXICITY
Benzene is not "drop dead if you see it" toxic. The lowest
reported LDLo for humans (the lowest dose that has actually
killed the MOST SENSITIVE human) is 50 mg/kg body weight.
This figure was reported in Pharmaceuticals Monthly. That
would be swallowing about 4 grams (a teaspoon or so)
for the average adult. Most people would be expected to have
a significantly higher tolerance than that. Not something to
fear, but don't lick your fingers after using it either, you might
get yourself sick. And certainly don't drink the stuff. But it
is highly volatile and unlikely to end up in your beer unless
you specifically put it there.
The lowest observed LCLo (lethal concentration in air)
for humans is 150 ppm. Again, a modest toxicity, but
not one to be dismissed.

Unless that's not the fact. In which case putting such
silly disclaimers in front of your warning would be
counterproductive. I'd rather see a frank discussion
of the LEVEL of hazard rather than either:
"run! run as fast as you can! Don't stop
and don't look back!"
or
"I'm a chemist. I bathed in the stuff daily
for 40 years and it hasn't effected me one bit."

Subject: further to open fermentation
Hi all,
Dave B. continues to claim that the problem with really open
fermentation is infection of the yeast. He uses two claims to back his
argument up: surface to volume ratio and the claim that open
fermentation is done in sealed rooms under positive pressure. First,
surface to volume ratio has *absolutely nothing to do* with whether the
*yeast on the surface* can get contaminated. In fact, it is just fog:
regardless of the surface to volume ratio the yeast is on top and
commercial fermenters have a much bigger surface area for contamination
to fall into. The simple fact is that Dave has provided no evidence to
support his claim that yeast heads on top of open fermenters get
contaminated. This seems to be case of common knowledge (protect your
yeast) leading to the assumption that there will be problem, regardless
of whether there is one. On the other hand, the *current* practices of
british and belgian commercial brewers and many homebrewers who open
ferment and top crop (harvest from the yeast head) is plenty of evidence
that he is completely mistaken. Dave goes on about these being
historical practices; this is just not true--many british breweries, for
example, open ferment *and* harvest and repitch the yeast from the yeast
head without contamination. The daily skimming of the yeast head that
some breweries practiced in the past is, by the way, evidence *against*
Dave's argument as by skimming the yeast they were not protecting the
yeast, but *exposing* the beer without harm! (By the way, Dave, if you
want to get some serious information on beer souring, have a look at the
appendix on soured beers in Wheeler and Protz's Brew Classic European
Beers at Home. It has absolutely nothing to do with 'contaminated' yeast
from open ferments.) Which brings me to point two: I've heard north
american homebrewers say many times that to open ferment you need sealed
rooms with positive pressure. Can anyone provide evidence that this is
what british and belgian brewers actually do? From what I've read and
seen they do no such thing. Try looking at some pictures of fermentation
rooms in british breweries. If you want to cover your ferment, by all
means do so, but there is no good reason to tell people their yeast will
be buggered if they don't.

Subject: decoctions, oops used the wrong word!
Hi all,
Marc's a little annoyed with what I wrote, I guess. I apologize for
sloppily using the wrong word. What I meant to say is to ask whether
decocting might lead to more difficult run offs with a lot of wheat due
to decoctions making the mash more *glutinous*. Sorry for saying
'gelatinising', which is, of course, the wrong word. The reason I asked
the question is having read the following in Wheeler and Protz, Brew
Classic European Beers..., 'Another problem with the decoction mash is
that the boiling can cause a glutinous mash that is difficult to run-off
and sparge, and requires a traditional type of lauter tun with a broad,
shallow grain bed for efficient sparging.'(p. 45)

Subject: Ammonia/Yeast bite
RE Thomas Murray's comment on HCL: In neutralizing Hydrochloric acid why
fool with ammonia? Grocery store stuff is pretty weak and laboratory
strength is pretty nasty because of the vapor. Sodium bicarbonate
(Baking Soda) alone works just fine producing CO2 gas, salt (sodium
chloride) and water as products. One pound will neutralize about 600 mL
of typical hardware store strength (8N) HCl. Of course lye (avaiable
from the hardware store) works very well at neutralizing HCL but lye is
pretty nasty too and its hard to tell when enough has been used. With
baking soda, you are finished when it quits fizzing. Another good choice
is chalk (calcium carbonate).

RE: Dave B's comment on "Yeast Bite": The last time I brewed I pitched
and went off to the airport expecting to be back in 4 days but didn't
get back for two weeks. During this time the kreuzen collapsed and all
that gradoo which normally gets skimmed fell back through the beer. This
beer definitely tasted funny at first and the funny quality was a sort
of coarse bitterness. The bitterness measured 36 BU. From the taste I
would have guessed it was in the 50's though I knew this wasn't the
kind of bitterness I'd expect from EKG. The initial tasting samples
were filtered because there were bits of resin floating about in the
beer i.e. the harsh "bite" was present even in the filtered beer so it
can't be attributed to yeast cells. Ninkasi be praised, this unpleasant
flavor has evanesced and this ale is quite pleasant. Bottom line is
that I'm a believer - don't let the stuff fall through.

Yes you've apparently missed the vast amount of research done implicating
Benzene as a human carcinogen. Plenty of work has been done on this, very
little having to do with special strains of mice.
I just did a quick search of the research literature through the National
Center for Biotechnology Information (NCBI) and turned up over 900 papers
going back all the way to the late 60's. Apparently however, benzene was
first implicated as a human carcinogen (acute leukemia) as far back as
1928...

There are varying degrees of poisoning, and exposure could be
life-threatening, just not immediately so. You can use these terms whatever
way you see fit but as for me, if something I'm exposed to can initiate a
cancer that will end up killing me in 20 to 30 years, that's still
life-threatening!

But I doubt any reasonable chemists would do so today!
People used to believe smoking cigarrettes was actually good for them too...

But, this could easily be a red herring - maybe they die of other causes
before they develop cancer. There is also a phenomenon called the "Healthy
worker effect" that may come into play. They may be more closely monitored,
may be more highly educated or health conscious than the population at
large, etc...
Also, there are studies out there showing increased risks of cancer for
chemical workers. One study looking at benzene exposure found an increase in
the incidence of liver cancer, interestingly without any corresponding
increase in the incidence of cirrohsis.

If you have access search the literature - they are out there in force.

Yes "let's" as in please give us YOUR sources which indicate that benzene is
not a human carcinogen!
Simply saying things like "Well, I breathed it in and washed in it but I
haven't got cancer" isn't good enough.

Again, search the literature

Whoa! I'm the first to admit that the system isn't perfect but it aint that
shabby either. True, causing cancer in mice or rats isn't proof positive
that the same chemical will cause cancer in humans but it certainly raises a
lot of red flags!!
> Every statement about chemical safety should

No, because this just isn't true. In the case of benzene for example, there
are neumerous studies using normal mice and rats (and probably othere animal
models as well). In addition, epidemiologic evidence exists for human
exposure. Of course, human studies are difficult if not impossible to do.
However there are cases where people inadvertantly did studies on themselves
(accidental high exposures) and these cases give us information as well...
That rodents treated with benzene get cancer means that /by definition/ it
is a carcinogen. There is sufficient epidemiological evidence to indicate
that benzene is also a /human/ carcinogen. Many studies on humans have
shown increased levels of chromosome abnormalities in circulating white
blood cells associated with benzene exposure. Occupational epidemiologic
studies support a link between benzene exposure and certain leukemias as
well as pre-menopausal breast cancer in women.

Pat asks "has the Hoegaarden recipe been tampered

Frankly I've never perceived the level of acidity that has been discussed in
the homebrewing community in all the Hoegaarden I've had in Belgium. I
wouldn't characterize them as "sweet" but neither would I characterize them
as sour or acidic. Light, refreshing, some malt graininess. Very low
hopping but the orange/corriander are not nearly as pronounced as many
homebrewers (and Blue Moon and Wit!) interpret the Wit to have. Subtlety
would be the key word to describe the spicing. I've often wondered if the
acidic character attributed to Wit (and often to Guinness) isn't just that
the beers have gone off a bit by the time they reach us locally? Did this
acidity become a momily? Hoegaarden in Brussels and Guinness in Dublin were
not, IMHO, acidic or sour at all.

Subject: dry hopping with pellets
Actually I dry hop with pellets often. No problems. When dry hopping in a
seconday carboy, I just toss them in. They settle out fine. If I end up
fining, that just helps the settling. I do have a fine mess stainless steel
screen on the end of my racking cane so that helps keep lots of stuff out of
the final beer. I also dry hop in my serving keg. In this case I made a
hop bag out of very fine "cheese-cloth" - actually it's not cheese-cloth but
some other material that's very fine. That appears to work great.

Subject: Refrigerator Woes
Reefer dudes and/or dudettes -
I recently procured a refrigerator (a relatively recent model) from a
neighbor. It worked quite well in his basement - he used it to store beer
(gasp!) and other carbonated beverages. The freezer portion was used to
store meat. He decided to get rid of it and asked if I wanted it (for free
- gasp! gasp!). So I took it.
While removing it from his basement, it was held nonvertical (from all the
way on its side to vertical) for approx 1-2 minutes. While placing it in
my basement, it was once again held nonvertical for approx 1-2 minutes as
well as being slid on its side down my basement stairs (in a controlled
manner - no free fall!). Between these nonvertical episodes, it sat
upright in my garage for a month or so.
When I plugged it in yesterday with a 14-2 wire extension cord I made
expressly for this purpose (the refrigerator plug is only 2 prong - no
ground prong), it coughed a couple of times and then started running The
freezer got nice and cold within a couple of hours, but the refrigerator
didn't and a wonderful electrical smell became evident. None of the
cordage (extension or refrigerator's native) was warm to the touch.
My question (and fear) - did I get oil into the compressor and ruin this
windfall? Is there something else to worry about from electrical components
being out of whack from the various relocations?
Thanks for any help - if you don't think the collective will care, private
reply is fine.

Dave! I'm offended! Blue Moon and "Wit!"?! Please. No, I base my comments
on past experience with Hoegaarden - albeit imported lending credence to
your "perhaps gone off" comment. And if I were to compare it to anything
domestic, it would be Celis White - theoretically the same beer by the same
brewer. At least very similar. In comparison to my last Celis White, this
beer is almost...
...insipid. I did not suggest that Hoegaarden was as acidic as, say, a good
gueuze; however, I've always been able to detect a light, refreshing
tartness. This tartness was not apparent in this last sample. Depressing.
Could it have simply been a fresher sample, as Dave suggests? Perhaps. But
then why wouldn't a fresh Celis White demonstrate the same lack of
character?
