Yeah, I made a small batch one year with excess comb/pollen/etc I had left over from a hive, and even after a few months it was, ...interesting, but a tasted bad/wrong. I was moving house and discarded (!) the last couple of bottles.

5 years later I was visiting a friend and they'd found a bottle of it that I'd given to them, and it was just awsome.. f'ing strong, but so smooth, and woah what depth of flavour.
