So I've been successfully brewing extract kits now for the past year and have been loving it. But now I have a problem.....the last three batches haven't turned out as nice. All the beer has a unique sour aftertaste to them. I'm confused as to what's going on....I think my auto siphon hasn't been performing up to par during bottling and wondering if the sour taste is due to oxidation while bottling. While I'm racking I'm noticing that there is a small air bulble that forms at the top of the racking cane exposing the beer to air as it flows from the top of the cane into the tube. Could this be causing the sour aftertaste? I'm a sanitatin freak so I'm confused as to what's going on.
