I'm fairly new to brewing, having only made about 8 batches. With the last 3 batches I've started using my own recipes and have been having problems with head retention. When poured, the beer foams, but quickly dissipates, leaving me headless. The beer is adequately carbonated, so I think I'm using the correct amount of priming sugar. I tried Munton's Kreamy X on the batch before last, but that didnt' help either. Any help would be appreciated.
