I just finished my 4th AG batch. Everything went real smooth for the first time. I never had any major problems but this is getting easier. This batch was a Autumn Amber and came out at 84% efficient. A very big thank you to Bobby_M and his 2nd NJ brewing seminar. It was really a great day of brewing and I am sure it helped me out tremendously. So far I have brewed a ESB, Smooth nut brown, Honey porter, and the AAA today. My worst efficiency was 77%.
