Wine is aged to give it more taste and general mouthfeel as well as colour and other properties. Rushing the winemaking process is widely considered a waste of good wine among homebrewers of wine and is highly frowned upon.
Here is a little cheat sheet I found to predict how different ageing times affect the wine in the bottle.
Wine Aging | Properties |
1 month | The definite minimum time it takes before you can even taste your wine, anything shorter results in bad tasting wine |
3 months | Wine has matured more and gained increasing flavours and distinctions |
6 months | The typical time for ageing wine, both red and white. Here your wine has a great taste and doesn't really need any longer maturing |
10+ months | Matures the flavour of your wine even further. Can create more bitter, unique flavours. The longer you age, the more unique |
