I am planning on making a Bohemian Pilsener tomorrow and am following a recipe in my Classic Styles book. The recipe is for a 60 min boil for the extract version of the recipe, but, it says that you should do a 90 min boil for all grain. If I do, should I switch the hop schedule around? ie. should my 60 min addition now be a 90, and so on?
Also, according to BeerSmith, the final ABV will be 7.1%, but, the recipe says 5.3%. I am not sure which to believe? I have found BeerSmith to be rather accurate in the past, so I might reduce the grain accordingly.
