I actually gave a lot of it away cause I thought it was a lost cause...
Nice. So I wouldn't let your friends know the reason for your sudden generosity!
Actually, in the few years I've been at this, I've only made one batch or so (beer) that had an off flavor. I think it was a little astringent in the aftertaste - I've gotten picky about taste since I started brewing. Anyways, few others noticed, so guess what. I became very generous with that batch.
If this works well, I'm gonna do a 5 gallon batch.
