Ok. I got an American Light Lager Kit from Austin Homebrew. Followed the directions to the best of my ability. The instructions called, at one point, to drop the temperature 1 degree per hour and it was gonna go over 12 hours. I couldn't do that directly. But over a few days, I slowly lowered the temp to the one specified in the directions. That was the only variation that I did from the instructions. I was told to expect a sulfer like aroma during fermintation. I did. I let it sit in secondary fermenter a few weeks later to allow everything to mellow. I put it in my keg. Let it carb up a week. Went to taste it.....and that sulfer taste was there. And it's strong. What can I do?
