So I have done 6 batches of mead now...or at least have them aging. The first four I used D47 Yeast and did not use any initial nutrients other than fruit. The bubbling in the airlocks was minimal from day 1. Now 4 months later there are still constant teeny bubbles running up the sides of the carboy with the occasional bubble in the air lock and they are all pretty hazy. I had two other batches using different strains of yeast and added nutrient during the primary those went CRAZY the first few days and now after a month and a half have no activity and are nice and clear. Is it possible after 4 months these D47 batches are still fermenting? I have racked all the D47 batches a few times but after a few days the little bubbles start again. Thoughts...?
