Why won't it dissipate? It does for my reds. I'm making the assumption that it is the Sorbate that makes my reds taste funny for the first year. I've since stopped adding Sorbate to my reds and they taste much better, much earlier.
I haven't tasted the affected wine yet. For some reason, all my wines taste bad to me at this stage. I can never tell if i am successful until about 3 months goes by.
