Ok guys so I'm on about brew number 12. I have always had this strange off flavor. I thought it was the extract so I switched to Ag with same results. It made me stop for brewing for about a year and back into it. So I made the bells 2h clone and kegged it (also a first). Ok started out in keg last friday and was tasting amazing. I was so excited. Well yesterday i started to notice that familiar flavor and today its stronger. I have no idea what this off flavor is or how to describe it. Its kinda bitter and mouth puckering and slighty alcoholic flavor. Lhbs says water here is perfect for brewing never checked though. I fermented slighty to high and pitched little to high around 70 to 72 but was down to 66 next day. Is this flavor just "green" or what. Pitched a large 1 liter starter.
