Subject: small bottles/sparge gap/yeast at priming time
re small bottles: Bud makes returnable seven-ounce longnecks. They come 35 to
a case. Hard to find, but easy to empty. I had to call around. Most places
don't bother carrying them. It's an extremely cute bottle. (Side note: at
first I felt funny asking dealers, "Got anything cheap that comes in a small
brown bottle with a pry-off cap?" But everyone I approached was friendly and
helpful. All you have to do is ask...)
sparge gap question: I sometimes spend a lot of labor based on assumptions that
may have no basis in fact. (This might actually be part of the definition of a
good hobby.) My latest obsession involved narrowing the gap between the
strainer and the outer bucket in my zillion-hole spraging system. Does anyone
know whether the amount of water below the strainer makes much of a difference
in extraction rates? Assume that I'm sparging until I hit a certain gravity
rather than a certain collected volume. Does it really matter whether there is
one gallon or one quart beneath the grain?
yeast at priming time: My first barleywine is carbonating *very* slowly. For
the second batch, I washed the yeast I took from the primary. I want to add
some back when I prime. Several questions. Should this yeast be put in a
starter first? Is there any danger of overcarbonation in this method? If
fermentation stops because the yeast has reached it's alcohol tolerance, how
does adding yeast of the same strain produce more fermentation?
Thanks

Subject: Homebrew Internet Relay Chat (IRC)
Greetings, brewers!
This post is to invite those with Internet access to join us in the IRC channel
#Homebrew. This
is a friendly channel devoted to the discussion of beer and brewing. All are
welcome. You will
need an IRC client, in addition to your Internet access. The channel is located
on the Effnet IRC
network. Below is a (partial) list of Effnet servers. (My apologies for the
length, but a server
list is a Good Thing (tm) when you are trying to connect to a channel). The
channel is usually
open, and the main operator (HiThere) drops in from time to time. If you get
in, and no-one is
talking, just hang out for a while. People drift in and out.
If you need more IRC info, or need to download an IRC client (software), go to
http://www.neosoft.com/~biscuits/
They have beginner FAQ's and links to software. (mIRC is the client of choice
for most IRC folks)
Join us online, and raise a glass with us! We would really like to get more
traffic on the
channel. Hope to see some of you there. Feel free to email me with questions.

Subject: Fizzy Barleywine, Typo, Mash Temp
Brewsters:
Jerry Cunningham asks how long it will take to produce fizzy barley wine with
2/3 cup of corn sugar. It could take as long as infinity, but probably some
friendly or not so friendly bacteria will help themselves to the sugar and
maybe
the other carbohydrates, eventually, if the yeast is inactive or dead.
Barleywine and mead have many problems in common if you are trying to carbonate
them. If the alcohol content is over 10% and the nutrients depleted you will
have a very difficult time getting it started, especially with beer yeast.
Champagne is generally fermented to below 10% in the first fermentation,
charged
with sugar and a *fermentting* yeast solution made from the base wine and
sugar,
capped and allowed to carbonate before disgorging the yeast via riddling, etc.
I recommend as I did the other day on a similar mead question, to prepare a
small potion of the barley wine with the fresh yeast and see if it will ferment
(probably it won't based on your experience). If so, use this krausen-style to
innoculate other bottles. If no fermentation ensues, try using a champagne
yeast like Prisse de Mousse now called, by Red Star "Champagne yeast" I think,
to carbonate your wine as the beer yeast may not be able to get much above 8-10
% in most cases. But use the above krausening procedure. Still problems? then
try ading a little nutrient and see if that helps.
- -----------------------------------------------------------
Hugh in Ft Collins points out what he thinks is a typo error in Greg Noonan's
book based on my quote the other day. I take full responsibility for the error.
It should read "six-ROLL malt mills" not six-row malt mills as I incorrectly
transcribed. Guess what I was thinking about! But they do sound a little
alike. Say six roll malt mill three times, real fast.
Thanks Hugh.
- -----------------------------------------------------------
Randi you can increase your beer's body by increasing the mashing temperature.
If you are using highly converted malts, skip the lower T holds and go directly
to 155-158F in a single infusion mash. Otherwise, do the 122F and 135F holds to
increase the soluble proteins and reduce gums, etc. and get a better head and
mouthfeel, but shorten them up from your current practice. Don't sparge at too
high a temperature or you may solubilize unconverted starch. Make sure the exit
temperature of the spaged wort is around the mid 160s F, but not higher and
that
when you add in the fresh hot water to the sparger that the sparge water at the
top of the column is about 167-170F.

Subject: Weight vs. Volume
I have been following the discussion on measuring priming sugar by weight
rather than volume. I have found that 3/4 cup just wasn't enough for me,
so I use a full cup. My question is: What is the proper amount of priming
sugar by wieght? I could just weigh a cup of my sugar, but I would like a more
definative answer.

I haven't seen anything else on the sorghum vs. millet identity
crisis, but it's worth commenting that sorghum *is* often
(mis)called "millet". "Millet" is, in common parlance, one of
those vague terms (like the British use of "corn") that tends to
mean "any substance that is like, but really isn't, a cereal". As
a parakeet owner, I have encountered three types of "millet", two
of which the parakeet won't eat, and one of which *nothing* in this
neck of the woods seems to be willing to eat (including the tree
rats).
If you intend to brew sorghum beer, buy "sorghum" and not
"millet". If you buy the latter, you could end up with a bag of
birdseed.

Subject: Canada & hangovers
Greeting fellow Brewers-
Just back from a most pleasurable trip to Canada. After many nights of
sampling the many brews Canada has to offer, both micros and the 'biggies',
in relatively large quantities (we only had a week!), we realized that we
always awoke the next morning feeling refreshed & energetic - no hang-overs!
We also noted that most if not all Canadian brews contain no preservatives,
and are labeled so. Do 'preservatives' cause hang-overs, or was it just the
refreshing Canadian atmosphere preventing them? What is it in U.S. mass
produced 'brews' that often destroys the following morning and why would it
be in there - a government plot to suppress the working man? (NO, I'm not a
militiaman - yet.)
Hey Canada, thanks for an incredible vacation; beautiful, clean, friendly,
Terrific Beer. Make room for another couple citizens, please!
Thanks also to all who post to HBD - you have helped immeasurably in my
pursuit of outstanding Beer. As I am a relatively novice brewer, I hope to
return the favor some day.

Subject: Silly Brewing Mistakes
OK, since the request for posting things you wish you never did is out,
here is my main one.
Crushing grain with a rolling pin.
I have had wonderful partial-mash brew recipes that came out nowhere near
what they were supposed to. Porters that were more like Negro Modelo,
etc. Turns out I was *never* able to get my grains crushed with that
rolling pin. I remade lots of those recipes after I got a roller mill
and found worlds of difference.
So, I now recommend the crush at the supply store (no matter how bad), or
the use of something better at home. *Big* difference.

In HBD#2175, Dave Burley reposts a very nice discussion of clarifiers:
>Polyclar reacts with the catechins (a type of polyphenol or

>hydogen bond to the proteins. This hydrogen binded complex
>between tannins and protein makes them less soluble

At one point I did an experimental design on using PolyClar and irish
moss to kill off chill haze. I found irish moss to be much more
effective than Polyclar at reducing chill haze. When I built a linear
model of the responses, I ended up predicting that it would take about
1/4 cup of Polyclar to eliminate the chill haze in my IPA.
I ended up using an optimized level of irish moss to solve my problem,
but at least in my hands, Dave Miller's suggested use level for
Polyclar seemed about right. YMMV.

Subject: Secondary ferment question
Howdy all,
Since the recent thread seems to be all about blow-off and secondary
fermentation i figured i'd ask sort of a silly question. I always rack from
the primary to a secondary within a few days after the major fermentation
has subsided. When the beer is in the secondary the only thing that happens
is that the yeast/trub settles out (if it hasn't already) and there is no
actual "secondary fermentation." Am I doing something wrong, or is this
typical of most "secondary fermentations?"
Sounds like a crazy question, but i just had to ask.

Subject: Dip'n Drain Efficiency
I think that I've resolved this issue already, but I'd like y'all's
thoughts on the matter (yes, I'm a Texian).
First, the foundation: In the various malt grain charts the potential
extract figures of the various types of brewing grains are given. These
have to be reduced by your brewhouse's efficiency if you want to predict
the original gravity a particular grain bill will produce.
Second, the global presumption: When translating a recipe from all-grain
to extract one presumes, unless stated otherwise, that the brewer had a
75% efficiency.
Third, the question presumption: The following question presumes that
(i) you're using grains which _must_ be mashed, but (ii) not in such
quantities that it makes sparging really necessary, i.e. you're trying to
obtain the special qualities of the grain, not necessarily their sugars.
The question: If the average brewhouse efficiency with a mash-and-sparge
is 75%, what would be the average efficiency with a mash-and-squeeze,
that is, the extract brewing technique wherein one mashes one's grains in
a grain bag, but instead of sparging them, you merely dip and drain them
a few times, then squeeze the bag? Would it be as low as 50%?
I think the real answer is that in the small quantities I'm talking
about, that whether it's 25%, 50%, or 75% that the grains aren't going to
change the o.g. by more than a couple of points and that in most cases
it's not going to make any difference.
But what in those cases where it does?
Nazdrowie,
Dave

Subject: re: HSA/Pump, LPG cylinder weight, Old yeast
Ken Koupal asks re. pumping hot wort:
>Is Hot Side Cavitation the same problem as Hot Side Aeration?
No. I suspose some air could come out of solution in the low pressure region of
the pump but, the air was in the wort to begin with. Cavitation occurs when the
fluid encounters low pressure regions within the pump. Some of the liquid boils
and produces water vapor (steam) bubbles. Steam won't hurt your wort. These
bubbles then collapse when they encounter higher pressure regions within the
pump. Cavitation is much more likely when you're pumping a hot fluid since it's
closer to boiling. The problem with cavitation is that it reduces the pump's
efficiency and, if it persists, will erode the pump impeller. For us
homebrewers, I doubt the later would be a real problem given the relative
infrequent usage of our pumps.
>Let's see, air (aeriation) shouldn't be introduced at the pump...
It will be present unless you arrange the piping (especially the suction side
piping) so that air pockets aren't formed. Large pumps have an automatic air
release valve at the top of the impeller housing to bleed off air which is
trapped in this region of the housing since the trapped air reduces pump
efficiency. I never worry about the air trapped in my relatively small RIMS
pump since the volume of trapped air in this part of the pump is only about 1
in3 and I've never detected any HSA.

This is called the "tare weight" is required by the ASME code to be stamped on
a propane cylinder's valve protection collar. It usually appears as "TW"
followed by the weight. John does have a good point about weighing empty tho'-
you can use the cylinder's stamped tare weight against the reading on the

CO2 cylinders since it's used to assess cylinder corrosion.

You're on the right track. Make a starter and taste and smell the results.
It'll obviously be yeasty but it shouldn't be offensive. If it's OK, pitch it.
Tasting and smelling the starter is a good practice even if you don't have
doubts about the yeast- it's SOP with me.

Subject: effect of inorganics on taste
Hey,
Some time back, Dave Burley wrote the HBD theorizing how certain
inorganics in various ionic and oxidation forms could influence
taste. I responded via private email, but at Dave's request am
displaying my note for all to gawk. I submit it as follows:
-------
Hi Dave,
This isn't my area so I'm replying privately so if I'm wrong then
I'll appear as a fool to a much smaller audience.
I think when you're trying to figure out taste sensation, you really
need to look at it from a biochemistry angle and not an inorganic
chemistry angle. You might remember that sour and bitter and sweet
sensations come from different regions of the tongue, although,
presumably, the substance is in contact with the entire tongue. So,
we could speculate that inorganic molecules may behave similarly
where certain ions have an affinity for specific taste receptors and
pH has only a mild effect on binding due to the buffering capacity
of saliva.
I don't know. Sounds good, though (!!???)

Dave was hoping he could arouse some discussion on the subject.

PS AOB lists MI as a state where homebrewing is illegal because the
word "beer" was not included in the legislation that allows hard
cider and winemaking for home use. We do have homebrew shops,
though. Is my beer ruined? Any Michiganders, Michiganians,
Michiganites, or whatever we're called out there know if the
legislation was updated or is it just being ignored as an oversight?

Subject: flaming lips (M. Jagger? I think not!)
John Wilkinson - Grapevine, Texas asked about flaming lips,...of flasks
and such. This one has been tossed around b4 and you'll likely get some
pretty wacky theories. So here the REAL story (at least IMHO- YMMV).
In using proper asceptic technique in microbiology labs it is
common practice to pass the mouth of a just opened flask or test tube
through the flame of a bunsen burner, or alcohol lamp in order to create a
positive airflow out of the vessel so that nasty microbes do not have an
opportunity to enter. This relies in part on the perioud of time the test
tube is open to be rather brief.
You generally do not want to heat it long enough to actually heat the glass
so much as just to cause the air to push briefly outward.
In transfering solid or liquid cultures the technique follows as such:
(depending on right/left handedness- assume here right) Hold the two
culture tubes to be used to transfer from and two in your left hand,
parallel with your outstretched fingers, but upright! Brace the tubes with
your thumb (hold your hand in a position as if you were about to toss a
ball straight up into the air. Now raise your fingers slightly so they
point upwards. Tilt slightly, 45 degrees or so, Rest the tubes along your
fingers. ) Sorry- I am NOT going to attempt an ascii drawing! Just ain't
gonna happen!
Hold your inoculating loop in your right hand like a pencil. Flame
the loop till red hot, cool slightly. Now using your most dexterious
finger, the pinky- wrap it around one or both caps and remove caps. Pass
tubes through flame, pick up culture onto loop, you may want to stick it
into the agar to cool if using solid medium, if liquid,- relax, no worries
mon -, move loop to fresh medium and spread culture or agar, or swirl
gently. Reflame tubes and recap.
Alternatively you may find it easier to open one tube at a time, pick the
culture, close tube, open medium tube, inoculate, close. The real trick
here is to remember to flame when the tube is first open, then flame before
it is closed. As- almost goes w/o saying- work in a draft free
environment. As clean as can be- away from kitchen, bathroom, musty
basements, basically choose the cleanest spot in your house, and before
working with cultures- spray down the surface with a bleach solution, or
EtoH, or lysol.
As for working with flasks- if you are pouring plates what you want
to avoid is having a drip form on the lip, flow down the outside, then back
up to the lip carrying a world of nasties along for the ride. Here is
where you can be a bit more thorough in your flaming. You will do best to
use pyrex for such a task. You don't need to heat the glass red hot, just
think about how long your cells can stand to be exposed to a flame before
they burst and rupture. It don't take much- this comes from a kid who once
fell on a BBQ chasing balloons at a party- trust me! A quick pass, with a
slight pause in the heat will suffice.
Use even less heat when pouring a culture from a flask because you
don't want the culture to be "ruptured" as it passes over the lip of the
flask into your fresh wort. A very good idea is to avoid -tipping the
flask to pour, then turning it back upright- that drip thing, ya know. If
you are pouring into multiple vessels from one flask keep it horizontal as
you move from one to the other.
You can use use flame to heat sterilize an inoculating loop
(nichrome wire) till it glows. Alternatively you can dip it in ethanol
then pass it through the flame to light the EtOH. Make sure it all burns
off. Works well for glass rods- sterile w/o overheating.
I hope this helps somewhat. Maybe someday I'll get some
photos scanned and post them on my web page. Maybe someday I'll have a web
page on which to post them! Check out a basic microbiology laboratory text
for more details and techniques. ( I used to teach such a class, FWIW )

Subject: Redhook dating question
For those of you who remember my post a couple weeks ago about Redhook
freshness dating, here is the reply I got directly from Redhook.........
[an excerpt of my post]
>My local grocery store (here in Columbia, SC) recently started carrying
>Redhook products. I snatched up a six pack of the ESB 2 weeks ago. I
>noticed that the bottom of the six pack carton had "12/95" imprinted in it.
> Thinking that I had just paid for 9 month old beer, I got steamed. On a
>more recent trip to the store, I saw the A-B distributor guy restocking,
and
>I asked him about the dating. He pointed out the "best consumed by" date
on
>the bottles, which said 11/6/96. He didn't know anything about the date on
>the carton, but felt confident that the beer was fresh since our local
>Columbia market just started carrying it.
[now the reply]

Dear Scott,
The dating on the six pack carton is the date that the package was created,
not the date that the beer was bottled. The best before date on the bottle
is the date the beer will stay fresh 'til; if the beer is keep refrigerated
it will last for weeks after the best before date. When the beer is bottled
it is given a best before date 110 days after it was bottled. So if your
beer bottle says 11/6/96 then the beer was bottled on Friday, July 19.

Subject: Second triple decoction
I did my second triple decoction on a Czech pils yesterday, and boy are
my feet tired. A little over 6 hours for the mash. I got a OG of 1.046
from 16 lbs of grain for 12 gallons. 34.5 points ain't to shabby. I got
32 points on my last attempt and it sure is tasty. This time I used the
authentic Czech Pilsner 3-mash schedule from Randy Mosher's The Brewers
Companion. Great book for anyone who doesn't have it in their brewers
library. I used Wyeasts 2278 for both. On my first attempt the sulphur
smell produced during fermentation had me a little concerned, but it
vanished during conditioning. If anyone wants to try this schedule and
you don't have the book, let me know.
Cheers

Subject: Mash-in Techniques
Here's an idea for getting the water into the grain without starch
balling. (maybe)
Put a hose, that reaches to the bottom, into the empty mush-tun, add the
crushed grain or grind into the tun, connect the hose to the hot water
tank and add the water. This way the water rises from the bottom.
Since I'm a extract brewer, I haven't tried this, just a thought. Any
all-grainers out there willing to experiment?

Subject: Style suggestion request
Hey,
I have several important events/milestones rapidly approaching, and I
would like to celebrate the arrival of each with an appropriate brew.
I am a relatively new brewer and have only 3 extract and 7 or 8
all-grain batches under my ever-expanding belt. :^(
I have the capacity to lager 8 cornys at a time (more if I use a
friends fridge too), so lager suggestions are more than welcome. I am
hoping to brew beers which are appropriate for the time of year as well
the occasion. The "events" are as follows:
1. SO's 30th B-day in early November. (No pumpkin suggestions,
please)
2. The birth of Assistant Brewer # 2 in early March (but I've a
feeling it will be between Feb 20-28).
TIA for any help/suggestions. Private e-mails are fine.
Prosit!

Subject: SPAMM Problem/Limit posting
The incidence of SPAMM on this digest, as it is across the whole of the
Internet, is increasing. I remind you of the Viewmaster and VGA SPAMMs of
last week. This problem is going to simply get worse and worse as the
Internet is brought down to the level of the least common denominator, as
have television and the postal system. We can do something very simple to
protect our little corner for a little more time.
Restrict posts to subscribers only.
Frankly, I don't care about any whining arguments about "inclusivity", or
fairness or open access or attitude or political correctness. Frankly, I
don't care if 200 or 2000 or 20000000 people have their posting privileges
revoked. If one wants to participate then simply subscribe. Come on
people, this is a no-brainer, we're not asking for your first child here.
The number of SPAMMers that will take the time to subscribe is miniscule -
these slimey, lazy, cowardly, gonadless, miscreants are looking for fast,
free, exposure at the public expense. If the HBD can be read and posted
to without subscribing, then what makes it any different than a newsgroup?
If, in fact, we want newsgroup functionality (I don't) then why are we
putting Shawn through all this grief, work and expense? If we want
absolute inclusivity then let's simply terminate the HBD and all
participate in rec.crafts.brewing.
Please don't email me personally about this. This is an issue for the
whole group, and if you have something to say, then share it with the
whole group. Or let Shawn know what you think (shawn@aob.org). Perhaps
we can come to some agreement on this.
