What happens in a bottle of wine as it ages?

"It is not completely understood what happens in a bottle of wine as it ages, though there are certain things we know for sure. As a wine evolves, the primary fruitiness evolves toward earthier, more complex odours and flavours. Tannins in red wines become less aggressive. Acidity will also become less present, giving the wine a creamier, smoother texture. White wines, which are more sensitive to oxygen, often acquire nutty aromas."

 Great wines also the whites from Alsace (as on the picture) need to age, so take the risk at least for a couple of years, I would say. You will be rewarded ‪#‎jolisoleil‬
