Ok, I'm a noob. This was my second batch (first without an experienced brewer guiding me) and it is a brown English ale. It had the potential to be awesome. Good carbonation, good nose, good start and mouthfeel... then it falls flat somewhere in the middle. The big nutty flavor just isn't there.. or is very slightly there. It goes on to finish with a nice little bite and beautiful aroma. It's just missing the flavor. How sad. Such potential. Anyway, my thought is that maybe I didn't rinse my grains enough after steeping. Any other thoughts on what I might have done to miss the mark on this one?
