Well I poured out my first batch of beer. About 3 weeks ago I made a catastrophic error in adding almost 3 ounces of Lactic Acid to my mash instead of 3 millimeters. After talking to some folks I decided to ferment it anyway. Who knows.... Well today I tested it and i think the yeast must have died cause the gravity was 1.020. it was very clear but you guessed it. it tasted like vinegar. very sad. well i guess it won't be the last failure.
