Subject: Regarding Lurkers
I suspect that there are not so many lurkers as there are members who
just get their messages rejected.
It has been a long time since I have "actually" posted but there have
been many times I have attempted but been rejected, it has not
bothered me, I read HBD and gain knowledge, there are enough other
persons out there to reply.
Perhaps this will get through, I seem to stripped my gmail bare...

Subject: Mashing for a Czech pilsner
I'll be brewing a Czech pilsner this weekend and will start with RO
water, adding minimal amounts of salts to keep this water soft.
However, I've often heard that the amylases suffer if they are
lacking calcium, and 50 ppm calcium has often/sometimes cited as an
appropriate amount to target in the mash. Nevertheless, I see that
the published values for the calcium concentration in Pilsen water
are much lower than 50 ppm--more like 10 ppm.
I doubt the brewers in Pilsen are adjusting the calcium
concentrations in their mash, but I'd like to hear from the
experienced pilsner brewers out there if I need to adjust the calcium
levels in my mash to values higher than the published levels for
Pilsen water.

Subject: Re: What is an Apparent Rennarian?
Thanks to Steve Jones and Doug Hurst for their fine answers to Lance
Harbison's question.
I missed it because I was relocated last week to [1021.6, 176.2]
Apparent Rennerian, Anna Maria Island, Florida. Did you all feel
the dizzying lurch in the coordinates?
And boy, do I wish I were back there on the beach where right now
it's 80F/27C! We are supposed to have upwards of a foot of snow here
in Ann Arbor by tomorrow evening. And I have a miserable cold I
probably caught on the plane home.
Anyway, for my own, even more complete, definitive history of
Rennerian Coordinates from five years ago, see http://hbd.org/hbd/
archive/4235.html#4235-4
Now back to climbing out from under a pile of emails from being gone
only a week.

I see that in my rush to get through all this old email, I didn't
answer all of Mike Sharp's bread questions:

That was Steve Alexander's comment, but I added agreement a day
later. It means that just folding over the dough a few times, i.e.,
briefly kneading it after it is mixed, does help a lot.

In general, I think conventional baking is better for bread as it is
less drying.
As for steam, you do need a bunch of it at the beginning (first ~5
minutes) to allow the loaf to expand from the heat ("oven spring")
before the crust starts to set. A pan of water doesn't quite do the
trick.
I used to toss a half cup or so of boiling water onto the floor of
the oven just after I put the bread in, but my wife pointed out that
I was warping the oven floor. So I got an old cast iron skillet from
a garage sale and would heat it on top of the stove, then put it in
the oven on the bottom rack, put the bread in, then toss the water
onto the skillet and quickly shut the door. This worked well,
although I did crack a skillet once from getting it too hot. But
since it was an old, trashed skillet, it didn't matter much.
You want the bread to finish in a dry oven for a good crust.
Cheers
Jeff

Not in my experience. I bought a bag of Briess rye malt a couple-
three years ago and it didn't convert completely in a test mini-mash,
and an email to Mary Anne Gruber, now retired from Briess, confirmed
that some lots had sufficient enzymes to convert, and some did not.
Other suppliers' malt may be different, and Briess' may be different
now.

Subject: "No wait" bread
Did anyone else read about, or even better, tried, the "no wait" bread
technique? Here's a link to an article in the Chicago Tribune about it, with
a basic recipe included: http://snipurl.com/1yor5
The basic idea is that very wet dough will keep and stay viable for up to a
couple weeks in the fridge. You then pull off the amount you want to make,
let it "proof", and bake it. There's a book, of course, _Artisan Bread in
Five Minutes a Day: The Discovery that Revolutionizes Home Baking_.
I haven't tried it yet, but I definitely will.

My understanding is that this is simply the result of the liming
process for softening the water. While the pH is high, it is not
very buffered.

for the rising, or fermentation, of dough, I find that long and slow
at cooler temperatures gives more flavor. I guess something like
68-72F/20-22C. Similarly, if you use less yeast, the critters (wild
yeast and bacteria) that are in the flour have more of a chance to
contribute flavor that way. One seven gram packet of yeast for 2.5
lbs/1.1kg flour (my standard recipe) is plenty. It may take most of
a day from start to finish, but it's the bread's time, not yours.
I will, however, often proof the shaped loaves rather warmer in the
interest of time. Be sure to cover them with plastic wrap or put a
pan or warm water in your oven where they are proofing to keep a dry
skin from forming.
I assume that you will remove them when pre-heating the over. Be
sure to take them out a little before they are fully proofed to allow
time for the oven to heat.
Cheers

The most recent beer I produced with WLP500 is a little more restrained
than past attempts. I started it at 64F and let it ramp up to 68F over a
week. It is definitely more mellow. However, it still has a fairly
intense phenolic and possibly solvent character. I think that is just the
character of WLP500. My pitching rates, oxygenation, temp. control,
nutrient-level, etc. were all quite acceptable. This is the only strain I
have used that produces such an intense yeast character. I think I will
let it age and mellow. I just have a hard time believing this strain will
produce a Chimay-like ale.
Maybe i'll try using a lower fermentation temp. in the future or just not
use this yeast for awhile. I think the WLP550 leaves a character that I
prefer. Also, I am going to try to get some yeast going from a bottle of
Chimay, though the health is probably so low that it won't produce the
correct character anyway. We'll see.
