I'm quite new to wine making but have had some great success with a plum wine, and apple and feijoa blend and a kiwi fruit wine. However I made a big batch of mandarin wine and although it is beautifully clear it smells funky, kind of like off manarins with a touch of puke?!!! It doesn't taste much better. I made it about two months ago. I'd hate to waste the whole batch. Do you think it will get better with age, or is there anything I could add into it to improve it?
