Been a while since I last made mead. I need to find me a good source for some honey and fix this. Best I ever managed to make was a blackberry mead, a good while back. Used a whole lot of foraged berries, real flavory and unexpectedly sweet. After the yeast finished fermenting it was still full of sugary goodness so I added champagne yeast and fermented some more. Don't recall the abv I managed to get on it, and being the neanderthal that I am I didn't write it down.
