One of the most common terms used to describe wine. An oaky wine has the aroma and flavor of oak. When a wine is aged in oak barrels, it takes on those characteristics of the wood. The newer the oak, the stronger the flavor. Other essences commonly imparted by oak include vanilla, smokiness, and a roasted quality, the latter two a result of charring the inside of the barrel with an open flame. Some less expensive wines are given an oaky flavor by tossing oak chips or shavings into the maturation vats, or by adding liquid oak flavoring. Yes, it is possible to over-oak a wine.
