Hello Ale-X,
I think you are on to something here. This is something that Greg and I would
like to facilitate when http://brewsession.com goes live. (BrewSession is a
recipe designer and shared database, among other things.) An infinite number
of brewers sharing recipes and evaluations should eventually produce meaningful
scientific results.
We plan to allow brewers to tie BCJP scoresheets to their recipes and also fill
out their own evaluations. Given "enough" similar recipes and evaluations we
can begin to come up with results.
For the widely popular and simple styles such as pale ale we ought to come up
with a significant number of recipes that differ by one ingredient (yeast, base
malt, water, etc). Using this data we should be able to reach some meaningful
conclusions.

This is almost exactly our plan for brewsession. :-D Like you, we dream big,
so the first thing we want to put out is a recipe designer and some brewclub
functions. Watch http://blog.brewsession.com/ for updates.
Another thing that would be great to start is a DB of commercial beer styles,
logging their "style" against the ingredients they use, and their complete
specs, including CO2 levels.

We plan on tracking a number of subjective and objective data (such as
narrative notes and GU:BU ratios), but could use some ideas about compiling
results from experiments.

Sounds like you understand the concept.

Just moved to the great state of TX, Bryan to be exact, not too far from Austin.

My heatsticks cost maybe $1 to operate for the production of a 5-gallon batch.
A 20-lb. tank of propane (that costs $15-$20) makes maybe 4 or 5 batches
IIRC, for a cost per batch of $3-$5.

Dean, Greg, HBDers,
The BrewSession plan sounds pretty good! It can definitely work out.
One dream I kept having was for a CMS of brewing knowledge. Part
beerpedia, part RateBeer/BeerAdvocate, part Freebase for brewing, part
brewsoft. Tied with inventory management, brewclub rosters, LHBSS
order forms...
Because my dreams tend to be too big, the best strategy is most
certainly to start with recipe formulation and analysis. Accumulating
and repurposing data about recipe details. Distributed brewing
experiments.
We already end up discussing recipes quite a bit. Some of these
discussions could become increasingly formalized/formatted. IMHO,
nothing is more valuable in a recipe database than accompanying notes.
Some of these could be "narrative" ("the reason I used Simcoe is that
I was out of my usual hops"), others could be category based ("malty,"
"spicy," "tart"), others could be numerical (1.12:1 GU:BU). Some
things are subjective there but there is such a thing as
"intersubjectivity" and dialogue. Keeping a record of many of these
things "for future generations."
It's probably important to keep in mind that it should remain fun and
playful. But if a compendium of brewing knowledge is compiled, it can
include both formal data points and fun anecdotes.
As usual, I'm thinking out loud. But I like the BrewSession concept,
if I understand it correctly.
Cheers!
Ale-X on an OLPC XO-1 at JP's Java in Austin, TX having a
Clover-brewed Bolivian Jatum Kjari.
