I have made 2 batches of mead that are now coming to maturity. One at 11 percent, aged for 18 months and one at 18 percent, aged for 3 years.
I notice that both are very clear, beautiful bouquet and clean tasting, but with a bitter aftertaste. When I pour out the last dregs of the bottle into the glass, there is a little turbidity, but also a complete flavor change - there's sweetness added too that offsets the bitterness.
I wasn't expecting sweetness to somehow stratify in the bottle, yet I have this in both meads I've made so far - is this expected?
