My first batch of beer ever was a hefe and it had a good combination of banana and bubblegum flavors yet I have not been able to replicate it since. I used wyeast 3068 everytime and get plenty of banana but not that bubblegum I am looking for. I have pitched cold for clove and warm for banana but to no avail for the gum. Any recommendations?
I have seen an interview with a guy from wyeast who talks about fermenting on the low end for banana and on the high end for clove, which is the opposite of what you are saying. He also talks about under pitching for banana flavor and overpitching for clove. The pitch determines the flavor and the ferm temp determins the intensity of it.
