Subject: Experimental Base
"Experimental base." I like this.
And though I like both J. Ben's and Steve's post, I'm especially happy
to see that Steve seems to have grokked quite precisely what I was
aiming at.
In so-called "hard sciences," precision is often key. Imprecise data
points are worthless, precise data points are perceived as accurate.
It's a very useful system, especially for "mission-critical" work.
But we're homebrewers and there's no way a significant proportion of
us can get the level of accuracy and precision expected of data for a
peer-reviewed scientific paper. Even if we had the necessary equipment
(calibrated, etc.), it's not like we can really control variables in a
homebrewing environment. As J. Ben said of temperatures and such,
there are to many things to take care of to get good comparisons
between two batches.
But my humanist/social scientist mind wasn't really thinking about
comparisons between two batches. It was thinking about a broad
"experience base." Sure, individual brewers have done things with both
1138 and 1028 (Euro and London) strains which have produced
counter-intuitive results. And it's actually very hard to tell what
the yeast strain's contribution to maltiness really is, given a
limited sample size. But if you get people who have been trying to
brew malty beers with both strains, and they tell you about their
experience, you might end up discovering something you didn't know
(instead of con-/infirming something you thought you knew). Again,
because we're all doing this for fun, it's not about challenging the
brewing canon with a single data point. But it can be about "free
experimentation" and collecting results.
An idea I got (and I should tell Chris Colby before I leave Austin) is
that the magazine (or some other group) could pay brewers say $1 for
each brew batch data. It wouldn't push people to brew more and it
doesn't cover the hop price but it might encourage brewers to submit
there data points. Then, this database could be managed by a group of
people and all sorts of analyses could be done with the data. After a
while, it's even likely that the data accuracy might improve. And
while it's difficult to do good science with mediocre data, it would
still be an improvement over "old brewers' tales" (I like this) and
individual word of mouth if we could easily look at data points.
"Oh, see... Many people who used this strain didn't get a good
attenuation yet all those who did get a good attenuation mention
rousing the yeast during secondary fermentation. Might have something
to do with flocculation."
Steve's discussion of decision making is spot on. We are talking about
making decisions. The fact that these decisions have relatively
harmless consequences is, in fact, a good thing. We can (and do) take
risks. And we don't need to become lab rats to contribute to beer
knowledge, if we take a few good notes while brewing and tasting.
Again, I'm glad to see these "wild" ideas aren't simply shot down. I
don't feel incredibly strongly about them but I'm still glad they can
spark thoughtful discussion.
