Default Beer myth experiment

For my next brew I would like to divide it up into 2 or more fermenters and test a beer myth by changing the conditions under which each portion of beer ferments. The problem is that I am having trouble finding a myth that needs testing. Is there anything anyone here wants tested?

there a lot of (potential) myths involving yeast preparation:

1) it is necessary to re-hydrate dry yeast
2) high krausen starter is the best
3) pitching on a prior yeast cake is "good"
4) aeration stone is the best (you could try shaking one fermenter and aerating another)

I'd like to know...but am too cowardly to try... whether or not pitching your yeast hot but then cooling it into the right zone really messes up your taste too much. It'd be interesting to split up a batch and pitch the same amount of the same strand but start one at like 90F and the other at 65F

Under pitch one and pitch the other correctly. See if there is a flavor difference at the end.

Great idea! Liquid yeast with proper starter on one, same liquid yeast with no starter on the other.

I'm torn between an aeration experiment or an under-pitching one.

I can't think of any myth that hasn't been tested repeatedly. You might pick a specific yeast and ferment at the top and bottom of the temperature range, just for the comparison.

what david said, or pitching rate. pitch as much as you can possibly start in one, then pitch maybe 1/2 a smack pack or vial in the other.

Beer is good.

You can do this yeast pitching rate experiment if you want to, or you can pick up the latest BYO, where several brewers did several test batches ranging from 1/4 the recommended rate to 4x the recommended rate and compiled their results.
