Subject: culturing yeast
In HBD 781, Eric Mintz asks to start a discussion about yeast culturing. I've
finally read the yeast special issue of zymurgy, and I'd like to second his
suggestion. From my own standpoint, I would like to build up a collection of
various yeasts that I can use as needed. Although cost is one consideration,
my main reason for wanting to do this is that my only source of liquid yeast
is mail order and I'm tired of having to coordinate brewing around shipping
concerns. So far, I have cultured yeast from the bottom of my own bottles,
but: (a) I don't want to push it past one or two generations, and (b) if I
want to drink that last bottle but I'm not ready to brew then I'm S.O.L. :-)
So...I'm considering two options. First, slants, agar, and petri dishes, as
detailed in several of the zymurgy articles; and, second, a yeast bank
involving glycerin (?) and sticking the yeastie boys in the deep freeze. I
know a lot of you use slants, but does anyone have experience with the yeast
bank? The cost seems reasonable. Alternative Beverages sells a yeast bank
for about 6$ (U.S). The kit comes with 5 culture tubes, 4 ounces of "freeze
shield", an eye dropper, and a storage container. Additional freeze shield
and culture tubes are available. I don't know much about chemical glassware,
but I suspect the petri dishes, etc., would cost a bit more.
Some more questions:
1. How does the yeast bank compare to slants, etc.
2. What's a good source of innoculation loops, agar, etc., for non-chemists?
3. How long can the cultures in the various systems be kept?
4. How many batches do you get out of one strain?
5. How much refridgerator/freezer space is needed?
6. In either system, does the yeast degrade/improve over time?
7. What problems/pitfalls have you encountered? What advantages?
I thank you and my yeast thank you.

I really liked the gadjets issue but I find that I personally get the most use
out of the yeast issue. The grain issue is also informative but I wouldn't say
it is a 'must read'.

Young fermented cider is usually very tart due to its acidity (you don't need
to add acid crystals). It is unlikely to be vinegar-like from the activities
of acetobacter at this early in the game. Acetobacter spoilage results primarily
from the conversion of ethanol to acetic acid and therefore must occur after
fermentation. Spoilage is also a slow process unless you deliberately innoculate
your beer/wine/mead with a high titre of acetobacter. It's probably worth your
while to save your cider and see what it is like in 3 months. I also
noticed that you did not include a sulfite treatment of your cider 24 hours
prior to pitching the yeast. Judicious sulfiting is good insurance against
microbial contamination of ciders and wines and will circumvent acetobacter
problems.

A good question and the answer may at first seem contrary to simple logic.
Ale yeast flocculate (stick together in multicellular aggregates) much more
efficiently than lager strains. This is due to their bearing a higher
concentration of various cell surface adhesion molecules, the details of which
are unimportant. One would think that larger cell aggregates would fall out of
suspension faster and settle to the bottom, but that would only be true when
the liquid is still. The turbulence produced during active fermentation moves
the yeast through the beer and as ale yeast aggregates it forms a sticky yeast
mass which can cling together at the surface of the beer producing a luxurious
thick yeast foam. Hence the description "top fermenting". This phenomenon of
aggregated material being pushed to the surface by turbulence where it
aggregates further is also seen during the boiling of your wort when the
proteinaceous scum forms.
Although what I described above is generally true for ale versus lager yeast
the top vs. bottom fermenting delineation is not an accurate one to employ in
defining an ale versus a lager. Many ale strains exhibit varying degrees of
flocculation and the same applies to lager strains. What is more important in
our definition is the temperature at which the fermentation takes place. Lagers
are fermented cold (40-55F) and aged colder (32-40F) and ales are fermented at
warmer temperatures (60-70F). The levels of products (esters, acetaldehyde,
phenols, diacetyl) of fermentation which account for much of the personality of
a given beer style are strongly affected by the temperature of fermentation.
Irregardless of extent of flocculation, lager yeast are more active at lower
temperatures.

Subject: What is Canadian 2-row?
(Sung to the tune of 'Poor Lonesome Cowboy':)
I'm a poor lonesome Hoser and a long way from home....
Does anybody know what Canada Malting's 2-row malt is? In recent
private correspondence, Dr. John described Klages to me as "2-row with
the enzymatic properties of 6-row". This seems to describe the stuff I
brewed with back in the good ol' days when I was still living in
Toronto. You used to be able to get 100 lb. bags in quantity >= 6 at
the Canada Malting plant for $29 a pop, and Jake McKay sold 'em in
quantity 1 for $36 at Fuggles and Goldings (does anybody out there know
how Jake is and if F&G is still in business?). I understand that the
breweries used to use the self-same stuff. This would have been a good
thing for corn-brews like Blue (reputed to be 44% corn!), but Viv Jones,
then brewmaster of Upper Canada, complained in 1988 that the stuff was
_too_enzymatic_ (!!!) and that UC was having to use some imported stuff
in order to keep the final gravity up.
So my question: is CM 2-row Klages? Partly or completely?
And does anyone know where a poor expatriate banished to the wilds
of Long Isalnd could find some, even if it's not at the incredible
price of .29/lb? (How much is that in _real_ money?)
By the by, I almost always used a one-step infusion mash with the stuff.
(I seem to recall Viv Jones saying Upper Canada did the same.) I
never got a haze at room temperature, but chill haze was sometimes a
problem. On the other hand, I sometimes got chill haze with a
step- mash, so I can't reject the null hypothesis.
In #781, Jack Schmidling says:
> it took an hour to bring the mash from room temp to 154 degs ...
If you want a "true" infusion mash and would also like to save time,
just strike with hot liquor. You'll have to fine-tune for your
own equipment and methods, but I bring about 3 gals. water to about
162 degs and then add 8 lb. grain. The temperature settles at >=150
and I can adjust upward with a little boiling water if need be.
(PS: this may not seem like a very stiff mash, but I'm using a bruheat
with a hanging grain bag...there's about 1 gal. below the grain.)
Also, Jack, I urge you to collect more data points before concluding
that a single-step mash gives a lower yield. In my experience there has
been no difference.
Finally, let me put in my two cents in favour of the Corona grinder (mine
is a Polish look-alike). True, it's not a mill and it 'scrapes' instead
of crushing, but it does a decent job with very little flour if you set
it _just_barely_ fine enough to break all grains. There's no need to
spend a lot of money, and you get freshly ground grain. However, I
don't buy Florian's argument that it pays for itself compared to the
cost of brewing with extract: Saving money is not the reason to brew
from grain...love or lunacy are the only things that could justify
investing an extra 3-6 hours in each batch. (Well, OK, better beer
is another reason.)
Happy Holidays, all,

Subject: airlines transport
I had an experience similar to others in trying to hand carry a couple of
bottles (unlabeled champagne) in a briefcase aboard a flight from the
Colorado Springs airport. Xray picked up the bottles, the attendant insisted
upon examining them. I told him they were homemade beer. "How do
I know, if you want to open one and show me (?) that will do." Since I had
no way to open and recap I declined. He told me if I could get the airline
to agree to carry the stuff he would let it through. A hurried trip back to
check in, query to the supervisor, "Could I put the bottles in my checked
baggage?" No. "What if I had just put them in before checking the bags?"
"That would be ok, but you didn't. Now we know you/ve got them and you
can't prove what's in them." I left the bottles at the checkin counter,
they put my name on them and on return a week later, surprise, they were
still there unopened! I did not take this as commentary on the quality of
my brewing. On a later trip, not wanting to risk breakage, I took a couple
of similar bottles, this time with reglued Budwater lables on the champagne
glass. Same procedure at Xray, attendant examined the bottles, no questions.
Draw your own conclusions.

Kraeusening
I have a question regarding Kraeusening my medium to heavy bodied ales. I
tried this on my last batch using the formula outlined in Papazian. It
is only very slightly carbonated (but still very drinkable, of course!).
According to Burch, I should raise the S.G. by .005-.006 which I believe
makes Charlie's formula low by a factor of two. In any case, I need some
help from you Kraeuseners.
The Details: Extract/Mash recipe with I.G.=1.040 , Edme ale yeast,
two weeks in closed plastic fermenter, racked and bottled with 1.4 quarts

If you ever find a really good answer, would you send word? One thing
that I can pretty well count on is just at that moment where
it's critical that nothing be stirred up and that I be able to work
quickly (like, when starting the siphon to rack the cooled wort to the
carboy), a veritable Panzer Division of kids & animals will stream
through, and generally stop to (loudly) discuss matters right in the
middle of the "brewery", until I bellow. Sometimes it's not even that
easy to quell the riot -- I recall attempting to explain, as tactfully as
I could, the importance of bottle sanitation to a depressed French
psychiatrist who was sure that she was being very helpful to me by
processing the bottles through with barely a sidelong glance at the
bleach solution. Amazingly, no infection developed, but I sweated bullets
until the last bottle of that batch was gone. Recently an entirely
new dimension of the problem has developed: spectators! Call me a
grump, if you will, but I generally prefer to work alone. That way I
can truly focus on what I'm doing, and I'm less likely to end up in one
of those awkward positions where something must be done NOW, but the tool
needed to do it is filthy. Recently everyone I've ever met (brewers
excepted, of course) seems to have decided that, Gee Whiz, wouldn't it be
a grand thing to come and see Martin brew. I suppose that would be fine,
but they usually bring their kids to play with my kids (swelling the Panzer
ranks), and the last two such events have begun with the guest walking
right in and calling the sheriff, most recently because someone shot a
hole in their car as they were turning into my driveway (no, it's not
THAT kind of neighborhood)(And that story's actually a good deal weirder
than I've made it sound -- I'll tell it to you some evening, over a brew).
I don't think the problem's as much families as it is Karma. Disasters
that would NEVER happen when I'm raking up the leaves (ugh) seem to know
when I'm brewing. I had a realtor call me while I was brewing a batch
of porter to say someone was finally making an offer on the money-pit I'd
been trying to unload for over a year, and that the papers were even then
being faxed to a location a few miles from me. I could just make it there
and back during starch conversion. Halfway there, the water pump on my
truck blew ... (the porter turned out fine, despite a VERY long rest).

Subject: bottle fillers
Is there some reason a bottle filler isn't considered a necessary piece
of equipment for brewing?
I siphoned my wort from my brewpot to my primary with the bent-tube
technique. It went okay. I racked from my primary to my priming
container, and from there into my bottles, using a bottle filler. (I
sometimes think of this as a "bottling wand". It's a stiff plastic
tube, a little more than a foot long, with a gizmo at one end. The
weight of the wort/beer holds the gizmo closed, unless you press it
down against, e.g., the bottom of a bottle. This thing attaches to the
lower end of the siphon tube.)
Siphoning was a thousand percent easier with the bottle filler! To
stop siphoning, all I needed to do was lift the "wand". Very simple,
very straightforward to control exactly how much beer gets in the
bottle.
Do people not talk about bottle fillers because there's a problem? Or
because they're so wonderful, no one would consider siphoning without
one?

Subject: Best size for counterflow chiller
I'm putting together a little brewery, and I found out, somewhat at the
last minute, that my heat exchanger is not going to work as I'd planned.
So I need to make a "quick-and-dirty' counterflow chiller. My question
is this: would 1/4" or 3/8" tubing make the better mousetrap? Intuition
tells me that the 1/4" would allow a much greater wort-to-coolant
surface area, since there'd be more wort (relatively) on the outsides of
the tubing than in the center. That would be at the expense of
throughput, but I'd rather have cool wort exiting slowly than hot wort
exiting fast.
Is that logic good?
Thanks.

Uh, Kinney, I think the subject line about covers it. Jim Koch is a
shameless marketer, as you say, but he makes good beer. There *is* a
brewery in Boston, although some (most?) of the beer is contracted
out to Pittsburg. One of the Boston brewers will probably set this
straight. I don't think that Sam Adams lager is a "faceless, non-offensive
beer". It sure seems to have a lot more character than Becks or Heineken,
and I know people who don't like it ("it's too strong"). That's not to
say that there's not a number of microbrews (and homebrews) that blow Sam
away. The point is that Koch's *beer*, for the most part, is a flavorful
quality brew. Koch's *attitude* is something completely different.

Subject: Rolling Grain Mill, under $40
Whoof, I think I've begun the redeeming process of discarding my semi-yupster
lifestyle. Last weekend, I transformed my oh-so-trendy-at-the-time hand
crank pasta maker into:
>>>>>A ROLLING GRAIN MILL<<<<<
But you know, it did make good pasta - actually GREAT pasta. Oh well,
now it performs a far greater service.
This is my story:
All this recent talk about grain mills got me thinking how the budget
brewer could build such a gadget. After discarding a bunch of my own ideas,
reading over Jack Schmidling's design (which was well done BTW. Hats off
to Jack.), my eyes lit upon the dusty Atlas hand-cranked pasta machine.
So, they've pretty much done the engineering for you. Pasta machines
have two opposing rollers to flatten the dough and an adjustable gap.
After an afternoon of tinkering, the result is a hand powered rolling grain
mill with an adjustable gap that works just as fast, if not faster, as my
Corona Mill. Total cost: under 40 bucks. Man, I tell ya - I doubt I'll
ever use the Corona Mill again.
1. Buy a pasta maker, or sneak one out of a trendy friend's kitchen.
You can buy pasta makers at most kitchen stores, dept. stores, etc. They
run between $35-40. Out here in NJ, I got mine at Fortunoff's in the
Willowbrook mall.
2. Modifying the pasta maker. No disassembly required.
Now, it's time to take the shine off the pasta rollers. (Otherwise the
grain sits & spins) Get a grinding wheel bit for a power drill.
I got mine for about 3 bucks at my local hardware store. They've got
all sorts of geometries. Mine looked like a pink stone teardrop.
Anything will work if it takes the shine off the stainless steel.
Take that power drill (If you don't know how to operate one, watch an
old episode of "Mission Impossible.") and grind the
begezzus out of those shiny, smooth, adjustable rollers. You don't need
to dig. Press just enough to make a rough surface. Go back & forth in
a lengthwise pattern. Turn the crank, repeat again, all the way around.
3. You're done. Have fun.
Put in some grain and try out your new rolling mill. Iterate on the grinding
as necessary.
I made a hopper from a old pizza box. This'll take all the grain you can
put through it.
A pasta machine - makes a great Xmas gift for the brewer in your life. :-)

I get the digest by direct mail, but I could pick it up from newsgroup
rec.crafts.brewing. I don't find the rest of rec.crafts.brewing that
interesting, and I was never sure how consistent this cross-posting

One of the pasta machine makers has a grain mill. It looks much like
the pasta machine, but the roller are scored to "grab" the grains.
Since it is intended to make flour, a simple modification would be necessary
to crush malt. The cost is high, close to $100 I recall, so I have
not used one.

I can get a glass carboy from my local water distributer for $7.
The carboy comes filled with distilled water. Can I use this water

Subject: pasta mill
Ken Weiss inquired about using a pasta maker/cutter as a grain mill. I
tried this a couple of years ago. It doesn't work. Can't pull the grain
through.
Commericial roller mills have very large rollers, 6" diameter. Pasta rollers
are only and inch or so in diameter. That's probably the problem. A large
roller leaves essentially are long feed area into the cracking region. Pasta
rollers are also very smooth; I'm not sure about commercial ones. Does anyone
know if commercial rollers are roughened or what? Commercial rollers are used
to make chicken feed among other things.

Subject: Carbonation and Grain Mills
Rich Kempinski asked in HBD 779 about rescuing an under-carbonated
batch. I had one of these (batch #1...) and ended up pouring all of
the bottles back into my priming bucket, adding fresh priming
sugar and a fresh yeast starter and then re-bottling. A pain in the
a-- to do, but it did result in a pretty good ale.
A Dietz wants to prime without sugar to preserve flavor. The best
way to make sure you don't change the flavor is to save some of your
sweet wort (I have never done this, but have seen writeups of using
3 pints for a five gallon batch) under sanitary conditions and then
using it for priming. Don't remember where I saw that, but it was
a spli batch comparison of using sugar, DME, and sweet wort. The
sweet wort won hands down. I'm gonna try this one myself one of
these batches.
On roller mills - the reference in HBD 780 to building a roller
mill using the rollers from a grocery store checkout came from a
small book on building your own brewery. I don't remember the
exact title, but it was xerox style publishing and probably isn't
available any more. I do recall that the rollers were 4" in diameter,
and that there was a provision for adjusting the spacing. Although
there was a picture of the device, it conveyed very little
useful information on how to build it. For example, there was NO
indication of how the rollers were powered.
In doing some serious "wetware simulations" (i.e. kicking back with
a homebrew and thinking about it), I came up with several unknowns.
First, what are the critical factors in getting the grain to feed.
My simulations very easily showed the grains just sitting on the
rollers with not enough traction to get sucked in. Jack S has
dealt with this on small diameter rollers (1.5") through (I think)
longitudinal serrations cut into the rollers. I am fairly sure that
the rollers on a pasta machine would not work for this reason. The
4" rollers are probably big enough to work with smooth surfaces. Do
we have any Industrial Process engineers out there who could
calulate for us the minimum roller size for a smooth roller to
work effectively on the grains we use?
My second unknown was roller spacing. Is there a specific spacing
which guarantees a good crush, or does this vary with the grain?
Would adjustable spacing be required? That would make the
construction a bit harder.
What data can people come up with? Measurements of commercial
mills that work?
BTW - My series on keg boilers is coming along -- Part 3 got
stuck in the push down stack, but should escape soon....

In several previous posts, the use of Iodophor from Diversity Chemical was

and they only sell the stuff in a crate of 4 1-gallon containers. I asked
if I could get a 1 gallon sample, but he seemed very resistant (I think if
I pushed hard enough I could get it). I got to thinking that many of you out
there might like to get a hold of single gallon also. The stuff costs
$55.13 for the box of 4 1-gallon containers. I would be willing to buy
the case, take a gallon for my use, and sell the other 3 to anyone who wants
a gallon or more. I'll sell it for what it costs me plus whatever it costs
to ship it to you (provided the stuff can be shipped legally). If there is
some interest, please e-mail me and I'll get the process in motion.

Don't bother, it won't work unless you run it through several times at
progressivley closer spacings. That is why roller mills have multiple sets
of rollers and also why they are so expensive. That is also why the one I
made has, what amounts to teeth on the rollers to grab the grain. The
rollers on my pasta machine are so smooth that I doubt it would work at any
spacing.

>Since I moved my brewing outdoors, I have had experiences that none of

outdoors. One batch was 6.5 gal pre-boil and the other was > 8 gal pre-
boil. In both cases, I boiled it to under 5 gal in 1 hour.
Consider it a blessing. You can start out with more wort at a lower sg and
end up with more beer. I typically get 1.5 gal per hour boil off on my
furnace.

First of all, I have not seen HBD on rcb for quite some time, so it does not

I tired it, it doesn't work. The pasta mill rollers are too small in
diameter to "grab" the grain. The Seattle Brew Brothers have a mill
with rolls made from 4" pipe (ends welded, shaft installed, outside
turned true, about a foot long) and it seems to work very well. Only
one roll is driven, the other free-wheels, you have to get the
undriven one spinning slightly before dumping in the grain. It will
eat a fifty pound sack in about a minute. Very impressive.

I have written a filter that removes certain postings from the HBD.
It runs on unix computers. It only needs a handful of unix utilities.
You can attain a copy via anonymous ftp from lupulus.ssc.gov. Look for
pub/de-arf.shar. I have tested this script on SunOS 4.1.1 and Ultrix
4.2. I hear that it also works on a Unix-PC. For those without anon.
ftp access, I will mail a copy on demand.
I figure only one person will flame me for writing this. :-) My own
opinion is that it makes the HBD a lot easier to read, and it merely
automates what I have been doing manually for months. Since it is
written in sh, you can hack it to your heart's content, and perhaps
improve it.
Now for something homebrew related. In his book, Papazian says (p. 79)
... information about the contents of your drinking water supply is
available at no cost from your local water department
What exactly should I ask my water dept.? Should I call or write? Is
there a law that says they have to supply this info at no cost?
I have other questions about water, but I'll leave it at that for now.

Slight correction: Murphy's WAS an Irish pub with etc., etc., as they've
lost their lease, and so are temporarily without a home. Happily, they are
resuming work on a new site just down the street. No clue as to when
they'll reopen, alas, but it shouldn't be more than a couple more months
(he said, hopefully).
Couple of notes on your other mentioned places:
The Blue Moon is smoky as all hell, and drenched with attitude (albeit an
alternative attitude). Monday evenings (Opera Night) are good, since the
music frightens away many regulars; Thursday is Dead Night, if that's your
pint. Actually, I suppose every night is Dead Night there. Dress down.
The Red Hook Brewery keeps an attached brewpub, the "Trolleyman." It's
smoke-free, but a bit lacking in the ambience department, unless you like
to drink in your Mom's living room. They have live muzak on Monday nights.
Four taps, including one rotating of a cask-conditioned variety. Good
place if you don't mind young-upwardly-mobile types, or can ignore same for
good beer sans secondhand smoke. Beware: closes ungodly early (c. 10-11pm).

Subject: Re: boil overs
I'm way behind in my digest reading, but I haven't seen anyone mention the
method I use to avoid boil overs, so I thought I'd share it. What I do is let
the wort foam up near the top of my brew pot as it begins to boil. Once it
gets close to the top (not too close as I'm try to avoid a boil over afterall),
I remove the wort from the burner. I then let it set until the foam subsides
(a minute or so). When the foam has gone down, such that I can see the wort, I
return it to the burner. I watch it as it quickly returns to a rolling boil
and rarely will it foam up again. If the foam does rise up again (usually
meaning the boil wasn't going strongly enough before I removed it from the heat
the first time), I simply repeat the procedure. I've used this method for my
last 24 batches and haven't had a boil over yet.
