Does anyone know the alcohol % tolerance of wyeast 1335 British Ale II yeast? I know this is a really specific question, but I couldn't find an answer on the wyeast web page.
You may wanna check the byo.com website. Their last issues was all about yeast strains, but I don't remember what all stats they provided. It may at least point you in the right direction to finding your answer.
I can't find the info either, but I've found that any yeast that doesn't claim to be a high ABV yeast dies around 6.5-7%. If there are specific characteristics of this yeat you want for a heavier ale, just pitch a neutral white wine yeast after the bubbling slows.
