Is there a place where I can send off a couple bottles and have them tell me what's wrong with my beer? I've made 30+ all-grain batches now and almost everyone of them has been barely drinkable. I have yet to make a beer that I would pay money for. I'm done trying to troubleshoot as I've tried just about everything(too long to list here). I've tried a few brewers locally and they couldn't tell me. I'm at wits end and am sick of dumping gallons upon gallons down the drain. Thanks for any input......Mark
