I've been brewing for 10+ years now. I brew beer from grain. Actually only had one batch turn out "bad" but I expected it since I used scraps from other batches. I also make wine a few times a year. Never had a bad batch and at $50 for 5 Gal of wine you can't go wrong. Actually I haven't made a batch of either and I have a wine kit in the basement (juice and yeast). I think tomorrow is the day to start the next batch of wine. Will be perfect for Christmas!
DON'T USE THAT MR. BEER THING. Go get a bud if you are thinking of that!
