 We seem to have a concensus on the 100th article.

 Congratulations Mr Adams, you will soon be the owner of your very own
 MALTMILL.  As you article had little to do with brewing and I do not
 recognize your name, I suspect others share my interest in knowing what you
 plan to do with it.  Are you a brewer?  Will this make an all-grainer out of
 you?

 Now, to claim your MALTMILL, all you have to do is post a 1000 word essay on
 why my beer is the World's Greatest.  Then I will pop a contract into the
 mail that will only commit you to ten years of promotional tours, at your
 expense of course.  Upon receiving your signed and notorized copy I will
 start scrounging up reject parts and probably get one to you in time for
 Homebrew Expo 2001.

 Seriously, congratulations and welcome to a very elite club.  Most of us had
 to work a little harder for ours, but that's life.

 If you send me your shipping address, I will get it out to you.

 >Congratulations, Jack.  You certainly stirred up interest in HBD
 during the summer doldrums.

 There seems to be a range of views on this subject.

 >  A few weeks ago I was complaining here that my hop rhizomes weren't
 growing, so naturally they are now growing all too well.  I have assiduously
 pruned back new shoots.....

 I sugest you stop pruning your several vines that you have allowed to grow.
 Just let them grow and prune only the new shoots at the base.

 > Anyone with a climate similar to Cleveland getting flowers already?

 I have pea sized flowers one one vine in Chicago.

 Interestingly, they are only on the vine that I forced to grow horizontally
 when it reached the top of my six foot fence.  The growing tip has dried up
 and all growth is now in the flowers.

 Two other vines from the same plant were allowed to grow vertically up
 strings and they are three times as long and no sign of flowers.  It appears
 that they will yield many time more hops than the one forced to grow
 horizontally but will flower later in the season.

 Needless to say, I gave on on the fence idea for the rest of my plants and
 they are all climbing up string.

 They are Chinook, BTW.

 Good discussion on "wild" yeast.

 For those not aware of it, virtually al varietal wines depend on the
 indigenous "wild" yeast found on the grape in the field.

 Champaign yeast is scraped off of grapes growing in the Champaign region,
 Burgundy yeast comes from grapes growing there, etc....   Each type is
 supposed to impart a unique character to the wine and is one of the reasons
 Europeans have gone to such great lengths to protect the names of their
 wines.

 There is nothing evil about "wild" yeast, after all, that is how wine and
 beer were discovered/invented.  It is just that we have become technosnobs.
 We know how to scrape off a little of that special yeast and pure culture it
 to avoid contamination by any other undesired organisms.  We know how to
 sterilize our must/wort and be absolutely certain that it will be true to
 type.

 This brings up an interesting project, and fits right into the plans for my
 anticipated bumper crop of apples and limited crop of grapes and
 elderberries.

 I am going to try to pure culture the apple yeast if I can find the bloom
 that Jay is talking about.  All I have ever noticed on apples is the common
 rust which is also a fungus but not nearly as welcome.

 doing all malt recipes and been satisfied with the results?  Anyone else have
 any evidence to support or debunk my claims, above?

 I would like to expand the poll to find out something I have been alleging
 from lilmited anecdotal experience.

 First of all, I think you are right about step mashing being a waste of time
 with the malts we use as far as extract efficiency is concerned.

 I however, believe that a mashout at 170F+ is the best insurance there is to
 avoid a set mash and would like to hear from people who can support or
 disprove the hypothesis.  I have never had a set mash so I do not need to
 hear from others who have not.  I just want to hear from those who have and
 whether or not they use a mashout.

 TRUB.......

 One additional comment on trub....  I have been dumping the trub from the
 brew kettle into a gallon jug and letting it settle in the fridge over night
 and get a quart or more of wort that I can either sterilize and dump in the
 ferment or use for starting the yeast for the next batch.

 That's a quart of beer I used to throw away.  Put another way, it's a simple
 and freebe, 5% increase in yield.

Jeff Mizener sent me a direct mailing asking about German
oat beers. My reply bounced back, so I've posted it here:

Jeff,
Sorry, my information was second-hand. A beer-loving
colleague of mine went to a scientific conference in
Bavaria (on cereal storage products - proteins & starch) and at
the main conference dinner beer was served instead of wine.
He showed me the menu - there were several Weizens, 3-4 rye (roggen?)
beers (there is at least one rye beer available here in England) and
2 oat beers. He was very enthusaistic about the oat beers, but his
judgement may have been impaired by that stage....

Subject: Plating out WYEAST #3056


I just brewed a Weizen (recipe to follow) which is now
fermenting with Wyeast #3056.  I streaked a wort/agar
petri dish with a sample from the Wyeast pouch.  Since
3056 reportedly contains a 50/50 mix of s. cervisae and
s. delbrueckii, do I need to maintain a slant of each of
each of these strains and build each up prior to
starting, or can I maintain both on the same slant?

The latter sounds unlikely, so here's my question (?)...
How will I be able to distinguish between the two
strains on the plate?  Is 50/50 the best ratio to use
for pitching subsequent batches?

I would like to hear any and all experience on this
subject as soon as possible since my plate already had
visible growth as of this morning, so please email to me
and I'll summarize to the digest ...

Now for the recipe:

Weizen Schmeizen, 10 gallons

6.6# can IREKS Wheat Malt Extract (100% Malted Wheat)
6.6# can IREKS Light Malt Extract
2 oz Hallertau Leaf, Bittering, 60 min. (alpha=4.4)
1.5 oz. Cascade Leaf, Bittering, 30 min. (alpha=5.7)
 .5 oz Hallertau Plug, Aromatic, 15 min (alpha=2.9)
Wyeast #3056 from a 1qt starter. Lag time 6-8 hrs.



Bring 3 gallons water to boil, remove from heat and add
malt extract syrup (yes, all of it).  Bring mixture to
boil, add Hallertau bittering hops.  After 30 minutes
add Cascade bittering hops, 15 minutes later add
Hallertau plug (I used hop bags for all 3 additions).

Cool wort (about 3.5 gallons) to about 100F, siphon onto
another 3.5 gallons of cold tap water, aerating
vigorously.  This produced 7 gallons of wort with a
S.G.=1.065 (I get great extract efficiency from my
extracts!).

I intend to rack (dilute) this into two secondaries each
containing 1.5 gallons of water.  Since there won't be
any new sugars for the yeast to contend with I don't
plan on aerating the additional water.  I figure this
should get me to 10 gallons of what would have been
S.G.=1.045 beer, if I had the capacity (or deire) to
brew/primary the entire volume.

Pitched yeast starter @75-80F.

I'll post the results when I know them ...

Thanks,     -Chuck-

Subject: silcone again

Hi,
        Well since I started this I guess I should report
        on my progress. With all the various ideas flying
        back and forth I called GE Silicones and asked
        them.[I figured they should know-)] Well they sent
        me a sample of Ge Silcone RTV102 that is FDA/USDA
        and NSF tested. The silcone will leak acetic acid
        during curing. But that doesn't worry me just makes
        me hungry.

                Thanks for the help.

From: korz@ihpubj.att.com
Subject: ESP/culturing/malehops

First, I'd like to point out that there were *two* instances of ESP
(no, not ESB) in the last HBD.  First, I asked about the importance
of protein rests with fully-modified malts, which was telepathically
relayed to Larry Barello, who answered my question, and then there
was the request for brewpubs in St. Louis followed by Walter Gude's
review of Dave Miller's brewpub (I'm sure glad I didn't post right
away).

Secondly, I'd like to answer Chris' question about culturing from
commercial beers such as Sierra Nevada.  I've had great success with
SNPA yeast, both from Wyeast and from the bottles.  I have heard a
rumour that SN has begun filtering their beers (I hope someone can
dispel this rumour) -- I'm quite sure that their Pale Bock has no
yeast in the bottom.  The SNPA I have is a few months old and still
has yeast in the bottom.  I recommend you use a starter, Chris.  All
you have to do is put two tablespoons of malt in a cup of water and
boil it for ten minutes.  Cool that with the cover on the pot.  When
the mini-wort is at 70F, pour (from a foot or so above the sanitized
funnel -- for aeration) the wort into a bottle in which you've left
(as you had mentioned) the last 1cm of beer.  Flame the lips of the
bottles before every pour for added sanitation.  I usually use three
bottles of SNPA poured together into a single bottle and 8 ounces of
wort.  Attach and airlock.  If the beer was around 60F or so, there
is less shock to the yeast and it seems to start faster -- sometimes
in as little as 12 hours.  I suggest you wait 24-35 hours.  At high-
krausen, a 3-piece airlock will bubble about once every 1-2 minutes
(equivalent to 40-80 bubbles/minute in a 5 gallon batch).

Finally, a question:
What do male hops look like?  I think my Nugget may be a male.  The
"cones" look really tiny with 20-30  3/8" to 1/2" spikes sticking out
of them.  I'd be pretty upset if I raised this plant from a pup and
then find out I have to rip it out.  (Just for completeness, males
are unwelcome in hopfields -- they fertilize the females causing them
to make seeds instead of concentrating their efforts on lupulin.)

Subject: yeast/O-rings/Bully Porter


>I see no reason to go to a second yeast, such as a champagne yeast.

If you do, make sure that you use a large starter, and pitch at high
krausen.  There isn't enough O2 left in the wort for the yeast
to undergo multiply (and/or the high alcohol kills much of the
active yeast), so it's even more important to get the yeast going
before adding it to the already-fermented wort.

>Wyeast #1098 is (allegedly) the Whitbread 3-strain.

Any authorative information on this?  I've heard it before,
but I also thought that all the wyeast were single strains,
except for the Bavarian Wheat yeast.

 Beverage Cooler Lauter Tun
I am in the process of planning what equipment that I will need when I go to
all grain this fall.  For my lauter (and optionally mash) tun, I am considering
using one of those plastic cylinderical beverage coolers with a slotted pipe
system for sparging.  I know that this has been covered before, but I would
like
to hear from those who use this system, or a similar one, about the pros and
cons of it.  Additionaly does anyone know if where these coolers can be found
in sizes greater than 5 gals?

Please respond directly.  And thank you.

 Cream Stouts and Lactose

As I understand it, lactose is often added to cream stouts.  Since the lactose
is unfermentable by normal "beer" yeasts, it remains in the final product to
give it a sweet, "creamy" flavor.  Unfortunately, lactose is not only
unfermentable by the yeasty-boys, it is also undigestable by many humans.  Does
anyone have a reasonable suggestions for a lactose substitute in these
recipies.  Perhaps there is a "natural" procedure for doing this, like using
more specialty malts, or higher mash temps, but my inexperience has left me in
the dark.  Anyone got a light?

The Yeast issue of Zymurgy has some good info.  What I have been doing lately
is to create a sterile starter (I use a pressure cooked - yeast flask or large
flask or quart mason jar) 1-2 Tablespoons dry malt per 500 ml of good water.  I
let the beer bottles settle for a coupla days after purchase.  Then I pour the
bottles into a pitcher immediatly putting the yeast dregs into the sterile
media, then shake the container, then store in a warm (75 deg f) place.  It
usually starts right up with little pinpoints of 'head', and is ready to go in
a coupla days.  I then pitch that into a gallon glass starter of 2 liters and
taste it for infection.  When the 2 liters of starter is ready to go I brew.
I've gotten great results this way, and you can inocculate a quart mason jar
and refriderate it it in a plastic bag, and it keeps for several months.
I would advise making a starter rather than adding right to the carboy to
decrease the lag time.

Subject: Root Beer Repair



OK so I should have know better than use tabs in my email. Let try again.

			OLD FASHIONED ROOT BEER

"Use strong bottles with patent stoppers or tie corks in securely. Use a stone
crock or granite vessell in which to let drinks stand while 'working.' Fresh
roots from the woods are always preferable to dried herbs. Select a cool place
in which to store the drinks; the longer they stand in a warm place after
bottling, the more effervescent they will become! When filling bottles, fill to
within an inch of the top.

1 cake compressed yeast
5 pounds sugar
2 ounces Sassafras root
2 ounces Juniper Berries
1 ounce Hops or Ginger Root
1 ounce Dandelion root
2 ounces Wintergreen
 4 gallons water

Wash roots well in cold water. Add juniper berries (crushed) and hops. Pour 8
quarts boiling water over root mixture and boil slowly 20 minutes. Strain
through flannel bag. Add sugar and remaining 8 quarts water. Allow to stand
until lukewarm. Dissolve yeast in a little cool water. Add to root liquid. Stir
will. Let settle then strain again and bottle. Cork tightly. Keep in a warm room
5 to 6 hours, then store in a cool place. Put on ice as required for use."

The Fleishman Company, Excellent Recipes for Baking Raised Bread, 1912


A couple of notes from the Oregon Brewer Fest

A great time! Lots of great beers

I worked next to Devils Mt. Brewery on Friday night. They were pouring Railroad
Ale, I saw no one from the brewery but they seem to still be in business

I had a long talk with someone who works at Widmer... they only use one yeast
and the repitch from batch to batch. The Hefe-Wisen is kegged young (4-5 days?)
and before kegging the recirclate the beer to reach the desired cloudly state.
