I know most of us have no difficulty drinking our ciders before they "get old," but I am contemplating a larger batch or two, and I was wondering how long does hard cider last before the flavor suffers? Does it eventually get skunky?
I've always related a skunky flavor/aroma from hops exposed to UV light, so I wouldn't worry about that too much. The biggest concern you will probably have from aging cider is oxidation. If not properly handled during fermentation/racking or if it's not bottled properly, you will end up with a cardboard taste that is REALLY unpleasant. I would think you could store it for years if you cork in champagne bottles. (for sparkling cider) You could also bulk age in kegs under a blanket of CO2 if you have access to quite a few.
