Not a big deal because this is just a one gallon experimental batch but I hate to throw anything away. I started some plum wine at S G 1.090. Stuff happened that kept me away for eight days and the S G had dropped to almost 1.00 by the time I could get in to a secondary container with airlock. Naturally it tastes like a wine that had been left open for a couple days which I guess means it's oxidized. Is there anything I can do to improve it enough to be drinkable when it is finished?
