Subject: Hop growing
In Seattle my hops are healthy and climbing.
One of the Hallertauers is up to 10 feet already. The rest are 2-3 feet.
They seem to work better climbing string than wood poles. I stake a piece of
wood into the ground, secure the string and tie it to the top of the pole.
The hops need little training to get wrapped up around the string. From the
top view they wrap clockwise; or another way to think of it is that they
"follow" the sun each day.
This year I have set four 10ft poles in rectangular arrangment, with four
support beams along the top. Every 8 inches of the beams has eyelets to
attach strings both length and width wise. The hops will then be free to
meander along the top of this thing and allow a nice place of shade.
Oh, the top beams are in a 10 ft by 4 ft rectangle.
Four hops failed to come up this year. Six survived. I thinned out each one
so that no more than 3 shoots from any one plant grow.

I tried brewing an American Pilsner once with a very light color, light
hopping and light body. It didn't turn out very well, probably due to
an infection. I understand that the lighter beers are more likely to
have this kind of problem.
A little reflection led me to the conclusion that I don't really want to
brew anything like BudMillobe anyway. It's pretty cheap to buy, and
doesn't really warrant the effort required to brew it.
My time and energy is going to be invested in brewing beers that *I*
like to drink. Anybody who makes remarks about "Brake Fluid" is welcome
to keep drinking that Wimpy Pasturized ___________ (fill in the blank)
to their hearts content. My homebrew is reserved for people who can
appreciate it.

I dunno. The version I've got seems to work fine. Of course, it's not

Ahem. Tums has NO aluminum in it. It is Calcium Carbonate. That's it.
Now, if you had said Maalox or Digel, you would be right.

Dos Equis (XX) is a Vienna-style lager, which is an amber beer made from lightly
roasted lager malt. I'm going to try a XX tomorrow using light Munich
malt (10 degL), Hallertauer hops, and Wyeast Bravarian yeast. I don't know
if the Mexicans use any adjuncts; I'm not going to. We'll see how
it goes.

Well, I converted a guy from Coors light to my stuff...
I had him try a bitter, a porter and a wheat beer.
I don't like my beer to be too bitter, so I generally use hops that are
low in alpha acids (5 to 7%) (Hallertauer, Cascasde, Saaz,...), and use
1.5oz for 5 gallons. That's what seduced him mostly.
For what my experience is worth...

Well, actually, it was UC Berkeley that went out on the limb. I was
just paraphrasing their article as well as I could remember it.

As has already been pointed out in this forum, wort is much less acidic
than many foods, e.g., tomato sauce. Also, wort is not cooked for as long
as many sauces and soups.

Mine looks pretty much the same above and below.

Well of course it's not the same compound that is found in Tums. If it
were, my homebrews wouldn't cause hangovers :-).
> ... (with very tight chemical bonds)?
Do you have information I don't about the nature of the chemical bonds in
Tums? Table salt (NaCl) could be said to have very tight chemical
bonds. But when it is dissolved in water, it breaks down easily into
the component ions, Na+ and Cl-. If my rusty memory of chemistry serves
(now I *am* going out on a limb), the breaking of chemical bonds and the
consequent dissociation into component ions is practically the
*definition* of "going into solution".
> But it is interesting to read that you taste no difference.
I didn't say that. I said I haven't noticed any off flavors/aromas that
seemed to be related to the aluminum. Neither did numerous judges in
various competitions.
I've never done an A-B comparison of identical brews boiled in aluminum
vs. stainless steel. Maybe I could taste the difference then. Maybe
not.
> Others have said the impact on beer flavor is drastic.
I have never heard *anybody* say that the impact was "drastic". The
warnings I have heard and read were more along the lines of, "boiling
in aluminum will subtly alter the flavor of the beer in a negative
way." I'll accept that without argument, and you may recall that in my
original posting I began, "Yes, stainless steel is better than aluminum
for brewing beer." I'd rather have stainless steel, but the fact that I
don't hasn't caused me any real problems.
My argument, on which I do not waver, is that the effects from boiling
in aluminum are either nonexistent or so minor as to be negligible for
practical homebrewing purposes. As I wrote before, "aluminum is not
*that* bad."
My advice: If you already have an aluminum pot, use it and don't
worry. If you can't afford stainless steel, buy aluminum and don't
worry. Direct your efforts and dollars toward the many more important
aspects of brewing, such as: sanitation; obtaining the freshest
ingredients; proper balance between malt and hops; appropriate water
treatment for the style of beer you are brewing; fermentation
temperature control; sparging technique; etc., etc., etc.

PS - One more thing: wort boiled in aluminum is less likely to scorch.
That is why the best stainless-steel pots are clad with aluminum on the
bottom (outside).

Subject: vienna malt vs. munich malt
Could I interrupt the great Al debate for a simple question? Can someone
out there tell me the difference between Munich and Vienna malts? I've
seen Munich described in at least cursory detail in books by Papazian and/or
Burch, but never Vienna. Oops, I hear a chain saw starting, better get out

Subject: Re: Brewing to Share
In case you forgot, the orginal posting inquired how to brew beer
for the Great Unwashed Non-Beer-Drinking Masses, specifically the Coors-
Miller-Bud crowd. On a slightly tangential note, I've served beer to people
who claim to hate beer, and the response I got was "I hate beer, but this
is good", from my very first batch to the present (OK, the present happens
to be my very second batch of beer, but I think that makes my point even
more). So, it may be that the only unsalvageable beer drinkers may be those
who drink cheap beer, while those who don't drink it at all can appreciate
a good brew.

Subject: Aluminum
To the person who gave that rather confusing discussion about tomato
pH, wort pH etc.. This is a rather dubious argument.
To introduce aluminum flavors into one's beer one would not have
to create pits in the pot by acid dissolution of it.
Having done Dr. Beer seminars fo r2 years now I will attest to
the sinsitivity of the palate (and to my inability to type well)
The human palate is sensitive to some substances at a few (7-10)
part per BILLION (as in billions and billions of Carl Sagans)
I don't know the exact sensitivity to aluminum but I'm SURE it
is well short of pitting levels.
To those who say they have brewed lots of batches and never tasted
aluminum in them. Sure you know what you're looking for???
One of the key reasons to do Dr. Beer seminars is that flavors
are very subtle and lack other stronger perceptual cues (like
sight) which help to clearly identify the substances. It is only
through practice that most people are able to uniquely discern
a wider range of substances. Practice meaning side by side
somparison of samples with and without the tainting flavor.
If you've always brewed in aluminum you're desensitized to it
by now. Unless you have the same beer with and without it is
incredibly difficult to isolate the aluminum flavor.
My personal opinion is that switching to stainless did have an
effect on elmininating metallic flavors. Perhaps doing a split batch
in two pots stainless and aluminum utilizing equivalent procedures
and the same yeast culture would allow isolation of the difference,
though it would be hard to be 100% certain there were no unaccount-
able factors this might help to highlight the difference.

Subject: Aluminum
I've used an aluminum canning pot for five years, now. Originally, I
used it to make extract recipes; now, I mash in it. I can vouch for
the fact that _no one_ has ever been able to attribute any off flavor
in my beers to the pot.
Another poster's message about the wort ph being 5.4 _is_ the reason
that aluminum is not a problem for brewing beer. Ph 5.4 is simply not
acidic enough to dissolve measurable (accept with a mass spec, or
other suitable device) amounts of aluminum during the short brewing
period. I will be most interested in seeing Dan Krus' AAS analysis
results on aluminum content. (Be sure to take a baseline measurement
of your tap water, Dan.)
BTW, Pete: The Aluminum in a TUMs _is_ the same as the aluminum in
your pot, after the TUMs has been dissolved in your stomach (ph < 3.0,
if I remember correctly).
