Re: [new_distillers] Re: Ending SG w/ baker's yeast?
- Thanks for the explanation; In a panic, I re-examined my work:
When I built the wash, I did two things - I used the basic 2#/gal, and then
adjusted the SG to 1.07.
After your e-mail, I went to the website and ran what I did thru the
formula and find that my 2#/gal gave a bit less potential then 14%, so at
least in theory, I haven't overloaded the yeast with sugar.
Yeah, I hear you about what yeast to use and it's not hard to find; I'm not
being stubborn, but others seem to have had luck using baker's yeast and I
wanted to give it a try.
Let's give this another day, then if action is still slow, I'll split the
wash and add water to both halfs. - Mike
