Oak
back side...
The use of oak plays a significant role in winemaking and can have a profound effect on the resulting wine, affecting the color, flavor, tannin profile and texture of the wine. The use of oak barrels can impart other qualities to wine through the processes of evaporation and low level exposure to oxygen. The length of time that a wine spends in the barrel is dependent on the varietal and style of wine that the winemaker wishes to make.
