Is there a good source that compares the commercially available yeast strains from the most common sources like White Labs and Wyeast?
I am thinking of something with homebrewing experience built into them: the differences of using WLP002 and WLP007 for, say, an English bitter, or WLP013 or WLP004 for a dry stout. What differences in character they make when using such and such recipe.
Of course, I would also like standard specs like average attenuation and temperature ranges to whether they are fruity, phenolic, dry, etc, but these are not so hard to obtain on your own.
