The darker berry wines can age for 2-3 years or maybe more (depending on acidity) and the more citrus wines are better 6 months to 2 years tops. Elderberry, for example, with a pH of 3.4 or so and good storage, can go 4-5 years or more (never made it past 4, lol). It is how good the area you store it in stays the same temps, how much sulphite in the bottle, how low of pH and the type of fruit that will determine when it will be good. I have had blueberry at 3 years that was even better than at 2.
