Knowing how much can last a wine in optimal conditions for consumption is an important issue to consider for any oenophile and especially for those who have a small winery.
The issue is complex, since wine can evolve for better or worse over time depending on the conditions under which has been preserved, the process of development and many other factors.
Since the wine is bottled and until it is ready to be enjoyed can improve during some time. The optimum time of consumption is when it has reached its maturity or maximum balance. From that moment begins to deteriorate, it loses strength and can reach to turn sour.
