Oh, yeah. I experiment with yeast constantly. A couple of the classes I
teach are on nothing but yeast and how to taylor your beverage through
yeast choice.

I've also heard people tell me that they've hit 30% with EC-1116 as
well. . . but that doesn't make it true. . .

You'll have to explain yourself here, because it makes no sense (to me
at least) as stated. Are you saying that you are skimming yeast from one
batch to start the next? If that is so, then in fact you have no idea
what yeast you are really working with. If not, please explain. I
culture yeast for fun, and I may be interested in what you are saying.

You say you make beer, but you've never heard of dry malt. That is
practically impossible. Not that it is impossible to make beer without
it, but that you haven't at least heard about it. It is merely malt that
has been spray dried (all water removed. . . pure malt sugars). EVERY
SINGLE BREW SHOP in the US sells the stuff.

Had what? The same batch of yeast? Have you ever heard of autolysis? No?
Look it up. Granted the only Yeast Lab yeasts that I have worked with
were all "M" series, I haven't worked with the type you mention. But it
can't be too terribly different from other yeasts considering its the
same basic organism. They live and die in pretty much a set manner. I'll
look for this YL01 tonight.

If making Mead makes me this happy,
imagine how drinking it makes me feel!
