If it were me and it came down to trying it or pitching it I would at least try it, spit it out and then I could throw it out without feeling bad about it
This is only because I was raised to never throw anything away (thanks mom & dad for that)
I have a batch of plum wine I made in 05 that...well, lets say it wasnt the worst or the best thing I ever had. Cant just ditch it. about once or twice a year I dust off a bottle, drink three sips, and THEN I can bring myself to pour the rest of the bottle down the drain
