steam stripping on the grain

[jward]

Looking for some clarity. It seems like I read that one shouldn't distill yeast to avoid off flavors. Also, if you ferment on the grain and distill on the grain it seems like the yeast goes into the boiler for distillation too. Am I missing something? My best guess is that while it may be a best practice to leave the yeast and any other junk from the wash behind in the fermenter, but if you distill on the grain then it's not in the cards to leave the yeast and one has accepted that. It may be some yeast varieties are more prone to throw off flavors when distilled and one avoids those when distilling on the grain. Maybe yeast don't contribute off flavors.
