After a fair amount of research and asking around about how long beers should be left in the primary, I found some descrepencies. My home brew store says no more than two weeks or autalysis will occur. Several books in the store also agreed. Jim Koch in his home brewing segment said he doesnt leave it for more than seven days. What do you guys do? Ive seen some people here who go way way way longer. What are the benefits of that as well as the pitfalls?
