Subject: Have Oxygen-Barrier Bottle Caps Ruined My Barley Wine?
Under the theory that the only dumb questions are those not asked,
I humbly submit the following ludicrous problem, suggested cause, and
request for assistance. It's drivel of course, but this is kind of a slow
time of the year on the HBD, so why not?
But, first a bit of background information...
I bottled a batch of barley wine 2+ months ago, primed with 1/4
cup priming sugar, and capped using oxygen-absorbing caps. The brew
carbonated after a few weeks, there was a visible layer of sediment on the
bottom of each bottle, it was drinkable, fair head retention, and I've
been aging a few bottles in my refrigerator ever since.
Two nights ago, I opened one and was utterly dismayed when I did
not hear that "pfffttt" sound that signifies carbonation. The stuff was
as still as could be, and even though the taste was not horrendous, I just
couldn't bring myself to drink flat barley wine.
I reasoned that the cap may not have been tight enough, and
resolved not to worry about it. Well last night, before opening another
bottle, I checked the cap first, and it had a good concave-ish dent to it.
But alas, the same results: completely flat beer, fair flavor-- and I
couldn't bring myself to drink it.
I KNOW this stuff carbonated before - I tried a few bottles - and
now it is not carbonated at all. Granted, my refrigerator is a cold one,
but that doesn't explain carbonated beer going totally flat.
My theory is that due to the low amount of priming sugar (1/4
cup), the oxygen-absorbing caps may have absorbed more CO2 than this beer
gave off; and that the reason it was not obvious before is, well, I really
don't know... Anyway, I've advanced a theory, and I would appreciate any
comments to help me with the problem, specifically, what caused this, and
what can be done about it?
Steve Schultz
P.S. One other item of data, probably not useful, but maybe: this barley
wine didn't ferment in the normal way, it almost exploded. I think this
was due to a healthy 1.5 quart yeast starter (Wyeast #1728, Scottish Ale
Yeast) and warm wort temperatures when the yeast was pitched. Almost two
gallons blew out of the five gallon carboy; I'm glad I was using a 1"
diameter blow-off tube. I've never seen a fermentation like this before,
and I have brewed barley wine before. Still, with all that, the taste was
only off a little.

A new micro-brewery has opened its doors at the Webberville exit off I-96 in
central-southern MI. Bobby Mason is the brewmaster and is having an open house
on New Year's Day 1996. He has an excellent hefe-weizen as well as a pale ale
and stout. His take home product is the Party Pig. Great Beer! IMHO. ed.

Subject: Scottish Ale and #1728
Marc Gaspard <mgaspard@mailer.fsu.edu> mentioned long ferments in his
attempt to duplicate Traquaiar House (sp?) Scottish ale:
> My problem seems to be rapid flocculation, ending up with a
> VERY sweet beer, usually a finishing gravity of 1.022-25.
Of course I don't know how his ale compares with the target product,
and I've never even had Traquaiar House ale. But, based only on
what I've done with about a dozen fairly strong Scottish ales and
on Noonan's book, I'd say your finish gravities are already too low.
I believe his rule of thumb for Scottish ales is fg ~= .33og.
The other aspect of these ales I picked up from Noonan is that
every step of the process is designed to make life hard for the
yeast. High mash temps (maybe you're mashing too high) combined
with low ferment temps. I would NOT raise the temp to get the
yeast going--58-62F for a long time is, I believe, the norm. It's
basically a lagered ale and you should expect a *very* long ferment.
If there is a better source than Noonan on this or if I've misread
the source, I'd like to hear other views.

Subject: My First Brew!
I just successfully brewed my first batch of homebrew (English Amber
Ale and it tastes great)! I have to admit, it was one of the easy
ones (just add water and sugar) but when I added the second batch
of sugar (corn) just before botteling, the beer started foaming
up and almost overflowed the sides! Should I have mixed the
sugar in more slowly? What can I do to prevent this in the
future? Thanks for any help.
***
When adding corn sugar for bottling, dissolve it first in very hot or
boiling water. For five gallons, you should be using 3/4 - 1 cup corn sugar.
Also - was your beer completely done fermenting? Did you take a hydrometer
reading of the specific gravity? How long did you allow it to ferment before
bottling? Most should be 7 - 10 days.
In any event - congratulations on your first venture! Like most of us, you
are probably very rightfully proud of yourself. Good luck on future brews
and welcome to the club!

Subject: Philmill modification
Hello All!
Has anyone out there modified a Philmill? I just got to the end
of my patience loading 2 lbs at a time into a cut-up Ram Rod bottle and
having the grist drift all over the place and the crank handle work its
way loose.
My quick fix was to attach it to a 2x6 board and use a 12" funnel
(the size that fits the opening of a standard 6 gallon pail). This is not
the easiest thing to support from just a hole in the wood. I know I need
more work here, any recommendations?
The grist was caught by a 4" to 3" tin pipe reducer, screwed
into the 2x6 to prevent it from falling into the grist. I cut a
semicircle to allow for the center shaft to protrude. The down pipe
fitted into a 4" soil pipe wall adaptor that was bolted to a 5 gallon
pail lid. to remove the pail, lift the 2x6/mill assembly. The crank
was reassembled with star washers (not supplied by the manufacturer).
I felt as I had gone this far I would motorize it as well. A 5/16 x 4"
bolt with the end cut off and a washer/star washer/nut attached to the
mill shaft worked ok. The electric drill attached to the headless bolt.
I don't know how long my drill will last with this load.
I believe that the drill should be running before adding grain to
avoid locking the motor and overheating the drill.
Anyone have any suggestions to improve this setup without getting
rid of the Philmill as I can't buy another one now.
Thanks in advance!

Subject: Suds SW Question
I'm a newbie all-grainer (recently discovered HBD - it's great) running small
test mashes (two step infusion) to determine efficiency and get some
empirical test data of calculated strike temps. I want to get a "warm fuzzy
feeling" before scale up to 12 gallon batches.
Question: I'm currently testing Suds S/W ver 4.0a for Windows (no, I'm not
yet registered but do plan on it) and the mash calc's have me confused. Here
are my #'s:
Boil Temp of Water:212F
Grain Starting Temp:55F
Desired Grain Water Ratio: 1quarts/pound
Strike Water: 0.50 gal @ 155F (calculated by Suds)
First Mash Temp: 122F
Second Mash Temp: 152F
Boiling Water to Add: 0.37 gal (calculated by Suds)
Water Absorbed By grain: 0.20 gal
Water evaporated during boil: 0 gal
Wort left in brewpot: 0 gal
Add 1.33 gal of water to yield 2.0 gal of wort (calculated by Suds)
When I added the 0.5 gal @ 155F to my initial 2 lbs. of grain, the temp
stabilized@ 140F not 122F. Of course I then checked with Charlie P. in "The
new Complete Joy of Home Brewing" and he says on P. 296 "there will a
temperature drop of 16-18F when a measured amount of water and grain are
combined (at a 1qt/lb ratio)". This seems to agree with my test data.
Am I missing something here? I don't think I screwed up the units anywhere. I
am very happy with the software otherwise. Please straighten me out on this.
Thanks in advance.

Subject: Will My Bottles Explode (WMBE)?
So many questions, so few carboys.
1st: Thanks to all who responded to the cider fermentation
question. In my opinion, the comments summarize to be: if you
want to recreate a commercial fermented cider, use a brewing
yeast (usually ale - Whitbread recommended for its clean
"taste"). Several people have used wild yeast - it is very
alcohol tolerant and ferments most all of the sugars => a
finishing gravity below 1 => relatively dry tasting. Some people
will not drink cider fermented with wild yeast due to the
potential for contamination and friends who have gotten ill.
Ideally the starting gravity is around 1050. Adjuncts can be
added to attain that starting gravity. Various adjuncts have
different impacts on the final product.
My question follows:
Based on feedback from many and relaxing and having several
homebrews I have accepted the fact that the fermentation temp.
was too low on my pilsner and I bottled prematurely. I don't
have the notes in front of me, but seem to remember the last
reading I took had it about 10-15 points above the ideal FG (i.e.
it was about 1/2 way to its ideal finishing point). Will my
bottles explode? Can they ferment in the bottle without turning
into grenades? FWIW they are standard 12 oz. returnables.
They've been "bottled" for 3 1/2 weeks. I opened one to give it
a try .... FOAM ... luckily I opened it up over the sink. From
reading Michael Jackson's book, these beers have a pretty darned
authentic pilsner head to them - a little more realistic than I
was aiming for. They still taste too sweet/unfermented. Any
advice re: bottle conditioning (fridge temps, basement ambient
temps etc...).
Thanks to one and all. Any response is appreciated. Private
ones should be directed to "W_GLADDEN@MAil.Co.Chester.PA.US"

Subject: Motorizing Your MaltMill(tm)
There have been several posts lately regarding motorizing the MaltMill(tm).
The schemes have ranged from pullys and belts to gear head motors. I just
use a $19.95, single speed, Black and Decker, 3/8", 1200 RPM drill from Home
Depot. I just removed the handle and chuck up the MM drive shaft. I grinds
a beautiful crush that appears to just the same as the hand cranked crush.
I'm getting about 32 points per gallon per pound. I have had the MM for
about 2 years and have rarely been so pleased with a product's quality.
Usual disclaimers. Just a satisfied customer.

Subject: Heat Evolution Primer
Text item: Text_1
Arrrrrgggghhhh !!!
Metabolic heat 101 :-)
>From Wang/Cooney
Heat evolution during fermentation processes is closely related to the
utilization of the carbon and energy source. When the carbon source is being
actively incorporated into the cell mass via growth, typically 40-50% of the
available enthalpy is conserved in the biomass, and the rest is given off as
heat.
When the carbon source is being metabolized for cell maintenance, all of the
enthalpy associated with combustion is released as heat.
If a product (i.e., alcohol) is being formed, the heat evolved per unit of
carbon source metabolized is between the two extremes.
Thus the amount of heat is related to the stoichiometry for growth and product
formation while the rate of heat evolution is proportional to the kinetics of
the process.
Heat evolution (Qf, kcal/liter-hr) has been related to oxygen uptake (Qo,
millimoles/liter-hr) by the following correlation.
Qf = 0.12 * Qo

Assuming you added priming syrup made from 1/2 - 3/4 cup of corn sugar and
water to your beer in the bottling vessel before bottling, you should just
wait a few more weeks for carbonation to be more complete. One week is not
quite long enough, though it may seem like an eternity! As for what you
should do, I would suggest opening one of the many great seasonal brews
available in the stores this time of year. Happy Holiday!

Hmmm. My puny little year old bottle of B.E.S.T. Iodophor omits this
"Never use..." warning, and my gallon size Arrow "Iodine Sanitizer"
says to use one ounce in five gallons of water.
Could be a recent development. I, too, am curious about the warnings
as it has been my (very, very long) habit to use the hottest tap
water I can produce (usually on the order of 130 deg F - is this hot,
or lukewarm?) to mix up my sanitizer. Never had an infection, and the
solution maintains its color for a long, long time.
Anyone?!?
