My last few batches of beer have attenuated more than expected, mostly finishing in the 1.002 - 1.004 range when the calculator from hopville has estimated the Fg to be in the 1.010 to 1.012 range. My last brew finished at 1.001, and for the first time I have noticed a slight sour taste to the beer. I assume I am dealing with some kind of infection, is it possible that I have had this infection for the past few batches and only now had it established itself enough to affect the taste of my beer? I have been using US-05 and S-04 and I brew extract.
