I made a critical error somewhere along the lines in my lager Oktoberfest (And this is actually the fourth time I've made it, so it should've been fine..) and it has a weird chemicalish taste undertone to it. I noticed it a bit before I lagered it and it was still there when I bottled and now again 4 weeks later I tried two bottles and couldn't even drink them. It seems like all the flavor is there, but the acrid chemical taste just cuts through it all.
This is the first batch I've ever brewed that's been actually bad and I'm at a loss as to what it could be or what I did wrong, especially since besides tweaking the recipe a bit, I did everything pretty much the same as I always do. I brewed a different beer right around the same time (actually at the same time) and that one's delicious so it doesn't seem like it's something unsanitary with my equipment..
So what'd I do wrong?
