So I brew all grain and extract. I live in FL, so cooling is always an issue during half the year even with my Therminator (which I'm not to pleased with). My final gravity never seems to fall below 1.020. It doesn't seem to matter what yeast I use or how long I let it ferment before kegging. I typically do 2 weeks in a primary and 2 weeks in a secondary. I use the agitation method to introduce O2 before pitching. My beers generally taste great but I'm concerned they are not reaching their potential.
