Oak barrels lose their signature flavor compounds with use, so they must be replaced every few vintages. In addition to adding oak flavors, new oak aging changes the tannin structure of red wines. Tannins from the wood transfer into the wine, giving it a stronger structure.
Why is wine aged in oak barrels?
Ultimately, wine is aged in barrels for flavor development, maturity, and longevity after bottling. After an oak barrel is made, it is exposed to fire to toast it. A minimal toast will lead to vanilla flavors and caramel notes, while a more toasted barrel will give smoky aromas.
What is the purpose of aging wine?

What is barrel fermentation?
Barrel fermentation means that the freshly destemmed grapes and their juices are pumped directly into French Oak barrels whose heads have been removed. Dry ice is added to cool the berries before the barrel heads are secured to seal in the must.
What does barrel fermentation create in wines?
