I have twenty litres of it on the go at the moment, it'll take a long time to mellow as presently at the three month mark it has a taste a bit like black banana skins, so I'm not planning on drinking it for another year at least.
I started a banana wine about two months ago. Last taste test was a month ago when I racked it. Smelled like a ripe banana but tastes like a green unripe banana.
From what I've read... the banana wine won't be very good until the 1 1/2 to 2 year mark. Yooper said that it is very strong tasting until that point. Once you're at the 2 year mark, it should have been mellowed out and the banana taste should have come back in full force. Can't wait to try this out myself...
