Hi Lauritsen. How long to age? That's a little like asking how long should string be... You want to age any wine for as long as it takes to taste as good as it gets. Mind you, if you start with good apple juice (pressed for hard cider or wine) and you chose the yeast carefully, then you can expect that wine to improve exponentially as the months go by. Apple wine after 6 months is far better than after 3 and after 12 months it can taste incredible. If , however, the juice was really made to be drunk unfermented and /or is bulk processed by large commercial conglomerates to be sold in supermarkets then the aging will still improve the flavors and aromas but not as much .. so you need to decide what the "cost" is of storing and waiting versus opening and drinking... I guess the point is that while fermentation may be over when the yeast have finished all the sugar there are still myriad chemical processes taking place that modify acids and colors and flavors and aromas - and indeed, you can see evidence of this as sediment continues to fall over months and months. How long should you age a win? As long as it needs to age.. Best way to know? open a bottle every two or three months and see the difference that makes... (I made a coffee wine that needed two years before it was drinkable and apple wine becomes heavenly after 12 months)...
