I can let it age for a long time, I don't have a good sense of taste, I mix my welches with 2/3 juice when I drink anyway, this wine will be for giving away to people who can appriciate a good wine. I'll let it sit till next fall anyway and then try one of the 4 test bottles. My blueberry will go long term too, but I'll take some of them out if there is a wine contest at the fair this summer, I'd like to get a ribbon to show. I used to get 1st place with my syrup every year so I stopped cause it didn't seem fair anymore.
