I did a peach that took over 2 years to come around, I threatened to pour it out mul times but my wife would stop me saying “give it time”. After 2 years it had a wonderful flavor.
I’ve got 2 or 3 batches that I absolutely loath. But the folks who like those flavors say they are great, so I don’t “flush” anything except absolute failures, the rest I bottle and find someone who likes them.
