Hi,
So I purchased the new Stone brewery book. It's great! But there seems to be a mistake in the recipe for their 12th Anniversary Bitter Chocolate Oatmeal Stout.
The beer was 9.2% ABV (stated in the book, and on their website http://www.stonebrew.com/12th/ale/) but the recipe says OG 1.099 to FG 1.022. That would produce a 10.3% beer. That's a pretty big difference, can't be just a rounding error. Their website also says the beer was 23.5 plato, which is about 1.099.
According to BeerSmith with a 1.099 OG you'd need it to ferment down to only 1.030 to get 9.2% ABV. I'm pretty sure the beer did not have that high of an FG - it would have been super sweet.
So does anyone have any idea what might have happened? Does Stone have some magical exemption to the laws of chemistry where their beers get thinner without producing alcohol (add water to the fermenter? haha)?
I think I'm going to shoot for 1.091 to get about 9.2%.
