So I ended up making a starter with wyeast 1007 and wort, and bottled after 3 weeks. I used the NB altbier kit. The og was dead on target at 1.052, but my fg was 1.006 for an ABV of 6%. Seems a little high for an altbier, though I love higher ABV beers anyways. I controlled the ferm temp pretty well for the first week, but had a little trouble in the last two weeks with my swamp cooler. Rose to 73F a couple of times, otherwise between 60-70F most of the time. Could the higher ABV be due to evaporation?
