Could use some advice on Brewers Best kits. I am about to brew my sixth BB kit, I've only broken open the first one so far, an IPA and it was great. The instructions say to ferment and condition the beer in a warm, dark area, with a stable temperature in the 64F - 72F range. My basement maintains a temperature of 70F, and has a concrete floor. I've read a whole bunch of posts that say that an ambient temperature in the upper range of what BB recommends could lead to off flavors. If that is the case, does anyone know why they would recommend these temps? I'm hoping my beers don't have off flavors, they didn't when I took gravity readings. Thanks.
