I brewed up a batch of Honey Bee Ale from kit I got from Midwest. I drank the last of this batch this last weekend and found that half of the bottles were pretty good and the other half were absolutely skunky in taste and aroma. Any ideas on what might cause half the batch to go bad?
Secondary 1: Porter (Forgot clone name)
Secondary 2: IIPA (Pliny the Elder w/ diff hops)
Kegged: Imperial Brown (Brewed by Surly through AHA rally)
