Subject: Secondary,
Brewsters:
Tom asks when should he go to the secondary and dry hop his pale ale. I
sugggest the appropriate time is when the major activity is over, a majority of
crud has settled out, but there are still signs of some fermentation. The
continuting fermentation will protect you from oxidation on transferrring.
Waiting about a week after pitching is about right for most normal OG beers. I
suggest you put your hops in a cheese cloth bag with sterilized marbles, boil
it
briefly ( 1 min or less), covered, in a small ( 1-2 cups) amount of water, and
steep it for a few minutes to reduce the population of bacteria and yeasties
and
add the bag and the water to your brew. Not exactly dry hopping but it will
give you more dependable results. Even though hops do give some bacteria
resistance, they are loaded with bacteria and yeast, as are most natural
products.
- --------------------------------------------------------
Tam asks about applejack lager. Good idea! Use apple cider (for you Brits and
others, US calls apple juice with pulp "cider" and fermented apple juice "hard
cider"*) fresh from the mill if you can, clarified juice in those store bought
jugs often has preservatives in them to stop fermentation, cider with no
preservatives in the store is usually heavily oxidized and is in some state of
fermentation. Instead of heating it to sterilize ( or should I say Pasteurize )
it, treat it with the equivalent of 1/8 tsp of metabisulfite (MB) per *five*
gallons of juice ( 1/8 tsp of MB in 5 tsp of water, take 1 tsp per gallon).
This will reduce the population of bacteria and yeasties substantially , and
stabilize the juice to oxidation. Add this about 12-24 hours before adding the
juice to your brew and the sulfurous acid level will be low enough not to
interfere with the fermentation Keep it cool, in the 'fridge if possible. If
you can, be there at the mill during the pressing and have them fill your jugs
which have MB already in them. Add pectic enzyme to the juice to prevent
cloudiness. The sugar content of the juice should be about the same as your
beer, so don't correct for that, but you will have a little more acidity, which
is what you want.
* I remember a British friend visiting the US for the first time being amazed
at
the cheapness and availability of cider - and was dejected when he found out it
was apple juice and not the good stuff. My first alcoholic beverage I made at
17 in my grandfather's barn was based on apple cider, brown sugar and raisins.
It wasn't great, but it was ok for drinkin' and fishin'.
- -----------------------------------------------------------
Jorge Blasig (hi Jorge) asks if he can prepare specialty malts at home from
pale
ale malts and grains, since supply of these in Uruguay is limited to
non-existent. I suggest you go back a few HBDs and read AlK's excellent
discussion of how specialty malts are made. Also, Papazian has some clues in
his book, Joy...
I routinely prepare barley (from an animal feed suppply store) and oatmeal for
my stouts at home by roasting them in the oven. Keep a sample from your last
roasting, so you can compare the color of the grains and get consistent
results,
since malts and grains have varying moisture levels.I usually dry the grains at
about 200F for a few hours before I high roast them at 450F for 20 min until
10% of the grains are black and 10% are light brown, to get better consistency.
If you need crystal type malt, soak pale ale malt in water for 24 hours in the
refrigerator ( to prevent mashing and fermentation and acidity formation).
Remove the excess water, place on a baking sheet (mine has 1/2" high sides) and
cover with aluminum foil and hold at around 200F - 212F for 45-60 minutes after
it has come to temperature, sampling and comparing with your standard. Remove
the foil and dry completely. Dried Crystal grain should be dark reddish inside
and crush like a piece of sugar when you bite it.
Vienna or Munich type malt can be made by roasting dry lager (but try your pale
ale) malt for three hours at 212-225F on an open cookie sheet. Longer and
higher is Munich style.
I use a meat type dial thermometer to measure the grain bed temperature so I
don't have to keep opening the oven door.
You can judge if the grains are dry by weighing a known volume (say a 1/4 cup)
on a simple balance scale made from a ruler with a paper cup on both ends
balanced with a round pen, taped in the middle and perpendicular to the ruler's
long axis, as a pivot and use coins or sugar as a counterbalance. Tape the
cups to the ruler with a loop of tape on the bottom and move the cup with the
counterbalance towards the center as it dries, until you get consistent results
about 1/2 hour apart. You can calculate approximately (the grains do shrink a
little) how much water was removed by simply taking the ratio of the distances
from the center for the two cups. Alternatively, you can move the pivot
position if that is easier than moving the cups.
A better drier than what I use can be made from a large pan with many holes
drilled in it smaller than the grain or cut the bottom out and affix aluminum
screening to give a good air flow. The advantage to this method is that you can
do more malt at a time. Be sure to stir occasionally if you do it this way.
- ----------------------------------------------------------
Chuch Wettergreen questions my ability to taste iodophor in beer taps that have
been sanitized with iodophor and not cleared. I can only suggest that you go to
O'Connors in Bround Brook NJ (rt 22E) and taste their beer. I spoke to the
barkeep about it ( DUH?), since every beer I tried and rejected tasted like it.
We are talking Pilsner Urquell, Dos Equis Blanca, Foster's, etc.etc. We got
there early in the AM after golf, (not THAT early) and were the first
customers,
I guess and ordered pitchers. Later beer was OK, but my 'buds were ruined.
Other times, I haven't had a problem and I don't think it was me because my
buddies had a similar response. You should have seen their faces after they
tasted the Pilsner Urquell ( or should I say PU). They thought I was nuts after
I gave them a big build up about how this was going to be MUCH better than the
american lager some prefer ( oh well, they are *golfing* buddies).
I suggest you try a little sip of iodophor if you think it is tasteless.

Subject: Pumpkin,Newbie,
Brewsters:
Part 2
AlK asks about the source of the taste of various salts. On the subject of
bitterness arising from the metal ion and/or the sulphate. In the absence of
absolute knowledge or a professional quote, I would vote for both, since I have
read it a number of times. I do know metal ions can impart bitterness, since I
am too familiar with iron and manganese in water ( although at near neutral it
could be the hydroxides - see below). Sodium chloride has a hot taste and is
reputed to impart a smoothing effect on beers. Does this mean that sodium is
not bitter? I guess so.
I speculate below:
In Chemistry 101 we learn that basic things are bitter and acidic things are
sour. This was a way chemists evaluated new compounds -(sometimes to their
detriment if their research subject was lead, mercury or arsenic compounds.
ergo
"sugar of lead" - i think it is lead acetate). So what is important in
determining sour or bitter when a salt dissolves in water, is"what is the
proton
ion to hydroxide ion ratio in the salt solution"? At 1:1 this is neutral and pH
= 7 so should be neither bitter nor sour. At greater than one, pH <7 acidic and
sour. At less than one, pH >7, and bitter
If one dissolves calcium sulfate in water it is probably ( I don't know)
neutral to very slightly acidic since calcium is a weak base and will take up
hydroxide ions for it's formation of Ca(OH)+ (pKdiss = 2.6) and sulfate comes
from a strong acid but will take up protons for its formation of ( HSO4)- ion
(pKdiss = 2.1). In all cases of divalent ions, Ca, Mg,CO3, SO4, there are two
equilibria to complicate things, In the case of Mg, Ca, SO4 the first stage
i.e.
M(OH)2 to M(OH)+ is 100% ionized. Not so in the case of carbonate, H2CO3 can
exist in solution of CO2 as you know. Based on this, sodium sulfate should be
alkaline, since the sulfate ion pulls protons out of solution to form some
bisulfate ions (HSO4, pK = 2.1) and the pH should increase. Sodium chloride
should be neutral since sodium is a strong base and hydrochloric acid is a
strong acid, which may explain its hot, ionic taste, i.e. neither sour or
bitter. Calcium carbonate (pK = 7 and 11 for carbonic acid) is made up of a
weak base and a weaker acid, so it is bitter. Sodium carbonate is made up of a
strong base and a weak acid and it is really bitter. I predict that calcium
chloride will be neutral to sour since the Calcium ion will take up some
hydroxide ions, whereas the chloride comes from a strong acid..
Although the first ionization for both Ca and Mg is 100% one could speculate
that magnesium sulfate should be less bitter than calcium sulfate and a lot
less
than sodium sulfate, since even though magnesium's first ionization is 100% pK
=0 its second is 2.6, Ca's second pK = 1.2, pK and the sodium would not take up
any hydroxides leaving the sulfate to take up protons and shift the ratio in
favor of the hydroxide ions. For carbonate the pKs are 7 and 11. Its salts
would be more bitter than the comparable sulfate salt.
In its reaction with phosphate, magnesium has a pK = 24 and calcium has a pK =
33, so it will theoretically take more magnesium to drop the pH than it will
calcium, but both will be pretty effective, since they are both really
insoluble. All pK info from Rubber Chem. Handbook 73rd ed.
So the answer is, as far as salts go whatever makes the pH go up above pH = 7
will make a solution bitter ( whether it is sulfate or carbonate taking
up protons for example). Therefore, with this simple model it is the sulfate
that is responsible for the bitterness of the pure salt of calcium and
magnesium
sulfate solutions. In the case of metal hydroxides or oxides, these are bases
and can supply the hydroxide which will be bitter and the acids which can
supply
protons and be sour, which is where we started. As we discussed above a wort is
not a simple thing, and will have many competing simultaneous reaction. In the
case of calcium sulfate in beer an excess of sulfate will be there relative to
the calcium because of the phosphate precipitation. These same reasonings
should argue that phosphate solution derived from phosphate salts should also
be
bitter, since they should be alkaline and they are, witness TSP (tri-sodium
polyphosphate) as a model.
So, it is the calcium and magnesium ions which exhibit control of the sulfate
and phosphate concentrations and therefore the bitterness. Which is the
bitterest on a molar basis, sulfate or phosphate? Based on the pK, I guess the
phosphate would be, since it has two equilibria to suck up protons vs one for
sulfate, assuming the first eqm is totally dissociated in both cases. So in
beer is it the calcium, magnesium or the sulfate and the phosphate which
controls the mineral bitterness? I submit that it is both anions and cations,
based on this reasoning.
Where this argument doesn't hold up is that beer has a pH that is acidic and
therefore we shouldn't taste any mineral bitternesss. Is it that our taste buds
somehow neutralize the acid taste out and evaluate the salts? or that taste bud
reactions are sorta like little pH meters? If this is the case can the metal
ions with a relatively insoluble hydroxide like Ca, Mg, Fe, Mn act as a source
of hydroxide ions and taste bitter,whereas sodium would not? I could guess so
and therefore both the cations and anions would be responsible the bitteness.
I said it was speculation didn't I?

In the interest of accuracy:
There is very little actually gained by prior registration of a copyright.
And, in fact, you have copyright to what you write, whether you make these
silly little notations or not. The most significant gain from prior
registration is that you can collect "statutory damages", you don't
have to demonstrate any losses by you or gain by the person violating your
copyrights. However, I doubt that even Mr. AK is spending the $20 per
document (I think that's the current fee) to register his copyrights with
the US CR Office.
The only significant thing gained by the copyright notice is that someone
reprinting your words can't claim he or she thought them to be public
domain. A minor defense, doesn't get you off the hook entirely anyhow.

The fair use doctrine is complex and covers many issues. However, under
no conditions does it allow for reprinting of *entire* copyrighted pieces.

Well, you haven't been here very long, have you? I've seen that, um, maybe

undrinkable swill, saying it's tolerable or some foolish nonsense. It's not.
And this isn't the place to discuss it. Or is it?
> How about keeping hbd to beer discussions.
I want a recipe for sorghum beer, and I want one now. I want to hear about
how to judge good sorghum beer from bad, how to serve it. I want to hear
about the history and cultural significance of it, just like I want to hear
about the Rhineheitsgebot. And, I want to hear if that history involves
Eurocentrism, or, hey let's just call it what it is, racism.
I think it's a fully appropriate topic for the HBD. What's NOT appropriate
is a BORING discussion of what is and is not appropriate to post here.
Next time you read someone doing that, ask them to cease and decist, politely
or otherwise, but do so in private e-mail. Go ahead, hit me now.
Okay, now what I want is for some boob to nitpick on Al K. for nitpicking
on someone else, and then encourage Al to launch into a mulyi-volume rant
in order to "defend" himself publicly, all the while admitting that the post
REALLY doesn't belong in the HBD. (That's from a couple weeks ago.)
Then, I want one of you to ask a relatively simple question, maybe about
bleach, and then I want ALL of the rest of you to respond to it, even if
you're saying EXACTLY THE SAME THING as the guy before you. What the heck,

They are offering a Brown Ale and a Lager, the lager wasn't bad.
Production may be slow since AB is replacing all of the equipment at the

Good evening all,
>>Ken S:
Magnesium is unpleasantly bitter in concentrations of around 30 ppm or
more.
I guess the speculation was that adding magnesium would supply a
bitterness
(however unpleasant) more cheaply than the equivalent (and more
expensive)
amount of hops.
<<
Burton water has about 60 ppm of magnesium.
My reading of the subject indicates that what Ken say is true, I just
don't understand why Burton beer doesn't have this unpleasant
characteristic.
I wrote:

>>Al K:
Nothing, to my knowledge.

Gee, Terry Foster seems to think that it enhances the dryness of the beer
and Greg Noonan states that it is very bitter in excess I take that to
mean that perhaps it is only pleasantly bitter when not used in excess.
>>Al K:
I don't think so. Both Burton-on-Trent and Vienna water have more than
60 ppm of Magnesium.
<<
What you say is true about Burton and Vienna, but these are exceptions to
the rule. Put 60 ppm in your beer and you will probably find that you
will become just a bit more regular and your beer will have a nasty
unpleasant bitterness to it.

In my experience, and using a very efficient counterflow wort chiller
(MAXICHILLER), I need 27 gals of 66F water to cool 5 gals from boiling to
71F in 8.5 mins.
I don't understand how 5 gals of 33F water from a keg could cool 5 gals of
212F water to less than 106F. Is there an explanation that I'm missing?

Subject: Gelatine, Calcium
Brewsters:
Jack Schmidling asks about the use of gelatine for clarification. It reacts
with the yeast through electrical neutralization of the charge on the yeast and
being of a high molecular weight can assemble several yeast bodies and
flocculate them. It is possible the protein is flocculating some of the salts
and miscellaneous organic matter in your water. Why not take some of the stuff
that sticks like glue, treat it with conc. nitric acid, then conc. ammonia. Of
course, only a drop of each and wash in between. don't mix the acid and
ammonia.
If it turns yellow and then orange, it's protein and likely some gelatin, but
probably not all of it.
In my sloppy chemistry days, I once had an orange fingertip from this reaction.
My lab instructor responded to my question about what to put on a nitric acid
discoloration on my finger with "neutralize it with ammonia" What a joker.
- -------------------------------------------------------------
John Posing writes about finding yeast coating on the bottles only on one and
the same side for all bottles. I've also seen this and assumed it was due to
static charge of some sort attracting yeast to one side of the bottle, but I
don't really know. I toyed with temperature, but discarded that. It is
possible that light striking the bottle generates a charge there. Does any of
this make sense based on your observation?

Brewsters:
Who says chemists and engineers are a dreary bunch? The following quotes from a
Chem & Engr. News Newscripts 13 May 1996 should dispel that idea and give you a
good idea of just how humorous they really are.
" The vast amounts of information available on the Internet include the
following account, supplied anomymously, of the Seatte Symphony's performance
of
Beethoven's Ninth some years ago. A long segment of the symphony - perhaps 20
minuntes - does not call for the bass violins, who decided to sieze the
opportunity and dash across the street to hoist a few and dash back in time to
chime in properly. To gain a margin of safety, however , one of the musicians
surreptitiously tied a string around the relevant pages of the conductor's
score.
When the group hied back to the hall and scurried into their seats they found
the conductor to be furious. and why not? It was the bottom of the Ninth, the
score was tied and the basses were loaded."
If you don't know baseball, you won't get it. Even if you do, maybe you won't.
If you do get it, maybe you'll be sorry.
- ------------------------------------------------------------
On this same page is a description of wheat that has been developed for growing
in space. Does this mean only wheat beers in space or can a space barley be
far behind? The wheat is called USU-Apogee is 18 inches tall and will grow 600
bushels to the acre, about thrice the normal yield. It will likely be grown on
the International Space Station scheduled for completion in 2002. Doug Ming of
NASA, who could probably have chosen a better phrase, says "'We're tickled to
death with Apogee"
NASA also says the wheat bakes OK but points out that "Making bread in space is
still uncharted territory"
Hey, so is beer making in space, but HBD was there first. I can see it now -

Subject: Re: HSA
I see that the subject of Hot Side Aeration has once again raised its head
in the HBD. I don't know how many years it's been now since George Fix
introduced the concept here, but it's caused no end of discussion since
then.
When I spoke to one commercial about it this Spring (a fellow who, like
me, has endless respect and affection for George), he utter some curse
about how much ruckus George had raised, and all for naught.
Seriously, how many of us have ever had *any* problem with our beers
that was attributable to HSA? Really?
I think that George's research was valuable, but that the entire question
of HSA is moot, unless beer is going to be stored for a long time, and
probably unless the beer is fairly pale and delicate. I'm certainly open
to debate on the subject, but in my own experience and observation,
the only significant oxidation problem is post-cooling; i.e., people
splashing beer when racking or bottling, or subjecting their bottled
beer to unhealthy conditions (such as heat).
I know there are a lot of brewers that like to FRET about stuff like this,
but for those of us who have real problems to deal with (like the damn
fruit flies that left me a nice dose of acetobacter or the mice that
want to eat my malt), HSA can likely be left on the shelf.

A tablespoon of bleach per gallons of water? Doesn't Papazian etc recommend
2 teaspoons per 5 gallons which is about 5ml per 10 litres of water?

I'll abuse this forum to solicit private email on this topic. Shawn expresses
one point of view, but I think it's a bit harsh. Here's another one: the HBD
has a great deal of value, and subscribers we all "know" have set up search
engines to add value to the HBD archives at Stanford. This is a tremendous
added value, since searchability and indexibility are real value multipliers
of electronic info, eh?
Well, that searchability may already take us into the gray area of Law, and
may already displease those who've previously contributed knowledge to the HBD.
But, extend that value-added by copying the HBD archives to a CD, adding index,
database, and search capabilities (of arbitrary sophistication). Now suppose
I've done this, and want to sell it.
Yes, it's the information in the archives that the buyer ultimately wants (but
already can get for free), but it' the value-added I THINK I'M SELLING. I feel
I'm charging for the CD media ($8), and whatever I feel the market will bear
for
the overlying software (that's my business).
Am I "trying to make a buck off other people's ideas", or am I just providing
an enormous enhancement to what is already apparently an acceptable idea (an
interface to the archives)?
Now, suppose I add a statement on my CD that says "All material in these
archives is the property of the individual contributors thereto, and is
protected
under US copyright law". Good enough? How does this concept differ
(philosophically, materially, morally, etc) from a free, primitive front-end to
the archives?
I'm NOT saying it doesn't differ. I'm asking your opinion via private email.

Subject: Need help with instructions
I am about ready to start my second batch of brew. My first was easy to
make and tasted good and all I did was follow the instructions included
with the kit. This time, however, the instructions aren't as clear, plus,
from what I read in the Homebrew Digest, you don't really need
instructions. What I have is: 3.5 lb Hopped Malt Extract (Munton & Fison
Old Ale brand), 1 pk dry brewing yeast, 1 bag (appx. 1 lb) sugar, and 1 bag
(appx. 1/8 lb) of sugar. One set of instructions (on the can) don't call
for any sugar or any boiling of the extract w/ water which is what I did
last time.
I know enough to add the yeast once the mixture is appx. 70degF, and to let
it ferment for the proper time, etc. Can anyone give other ideas or
instructions for using what I have to make some beer? Why does 1 of my
sets of instructions say to add 1/2 teaspoon of sugar to each bottle?
Thanks,
Matt

Subject: City boy turned yeast rancher
I'm trying my hand at culturing some yeast slants, and as expected,
I've run into some problems. I'm trying to culture straight from the
Wyeast pack into slants. The temperature here has gone up, and my
apt. was hovering around 85 degrees. This has caused the starter I
made to go like a bat out of Hades, and also liquefied my slants that
were made with gelatin. I've since set the starter in cold water to
at least slow things down a little, but I'm wondering if I should just
forget about the slants. It's been almost 2 days, and I've seen no
signs of growth. Is it still possible for the slants to recover? I'd
still like to get a culture from this yeast (1056), can I go directly
from the sediment in either the starter or primary to a slant? As
long as I've got your attention, what effect will the high temps for 1
1/2 days have on my starter (I'd at least like that to come through
ok). Also, do you swirl your starter before pitching it into the
wort, or leave the sediment in the bottom? Was that enough questions?

Subject: OK, I'll Bite...
Randy Erickson sets the bait...
> I hope Ken adds to the thread.
...and he takes it, hook, line, and sinker! Actually, Randy, you explained
it at least as well as I could have, so I'll just reiterate the lesson:
Electricity is like any tool -- use it safely and it'll work wonders; use it
foolishly and you're asking for big trouble.
The 220 / 110 "switching" I do is courtesy of a high-power diode that I can
switch in and out as needed; I'm actually controlling the phase in a crude
but effective way, so my power gets cut in *half* instead of reduced to
*1/4*. For boiling 6-1/2 gal wort in a 7-gal bucket, 1125W (power chopper
ENGAGED) gives a nicely-rolling boil. 2250W (power-chopper BYPASSED) is good
for quicker heating from sparge to boil. I've experiemented with a midpoint
power (1688W) using 110V; it too boils over, so the 1125W is probably about
as good as it safely gets. For more info on the Electric Brewery, see my web
page (URL below).
I think the key thing as others have pointed out is the WATT DENSITY of your
element. That's a measure of how much heat is produced on a given area of
the element surface. If you put all the heat (power) into the wort in one
small spot (a small element wire), that spot could overheat the surrounding
wort and scorch it. If you "spread out" the same amount of power over a
larger element, you get the same total heat into your wort, but each section
of element is contributing a smaller portion of the heat compared with the
first scenario. Thus less "local heating" is going on but the same total
heating is occurring.
I've estimated off the cuff that a large kettle with one of those F-16
burners can generate between 50 and 100 W/sq.in. on the bottom of the kettle.
I assume that whatever thermal effects occur are acceptable since this is
how so many brewers work. My electric boiler's elements run at ~54W/sq.in
during heatup and half that during boiling, and I've not had scorching
troubles. Dion "Mr. RIMS" Hollenbeck recommends shooting for absolutely the
lowest possible level in RIMS systems, and I would second that suggestion.
How can you figure the watt density for your element? Here's a quick'n'dirty
rule o'thumb: Most water heater elements I've seen have wires about 5/16"
diameter, which means you conveniently have about 1 sq in of surface area per
inch of length of wire. So divide the element power by the element wire
length to get the watts per square inch, and see how it compares with these
figures.

I personally believe that it would be a wonderful thing for the HBD
to be put onto CD-Rom, but I have also thought the same thing about a
friend's nationally syndicated car talk show, Jeff Brooks' "On the Road." I
told him I wished he would do it, but I don't think it proper for me to try
and rip him off by doing it with out his blessings.
I think that anyone attempting to perform such a feat with the HBD
should read the current Forbes magazine, Sept. 9, 1996, and peruse the
article on page 134, "Cops and Robbers in Cyberspace." People who wish to
use the works of others and those who wish to prevent such occurrences will
both be delighted, as they point out that there is very little that really
can be done, currently, to prevent such attempts, but they also detail the
efforts of others, who are currently actively seeking the test cases they
need to prevent such attempts, by making the first legal landmark cases
against the infringers. "Be the first on your block to be..."
As I say, I think it would be not a bad idea, but without the
permission of those who have gone before us, and as they are many, I feel
that this is not 'do-able', legally and/or ethically. As the AOB is
currently the 'maintainer' of the digest, I wish to state my desire that
they continue to offer the digest as a free and open forum for ALL who wish
to avail themselves of it.
I also hope that my dues to the IBS and the parent org, the AOB, be
used to pursue most actively, any who would use the talents and time of
those who have given freely of themselves to educate myself and the rest of
the collective, for their own personal benefit.
I believe that any who tread this path would be, quite rightly, in a
position of a precarious nature.
The point is, those who have posted to the HBD did so with the
knowledge that their posts would be used as THEY intended. When you use
their input for purposes, (and this is not to limit the use of excerpts
purely intended for educational/not for profit use) not intended by the
originators, you are violating their intent. This is, at this point,
actionable.
But bring on the lawyers! Someone has to settle this....
Not so Cheerfully,
Jethro

Subject: Stainless Brew Pot Problems?
Hello All!
I am new to this group and have a question that someone out there may be able
to answer. I have always brewed with an enameled brewpot and recently bought a
stainless steel brewpot. The problem is this: now when I make a batch of beer
it seems to have a metallic flavor to it. Is this because of the stainless?
The pot didn't cost alot ($25), is it "cheap" stainless? What should I do to
prevent this problem in the future?
Thanks in advance,
Bill
