after fermenting, the wine is stored for a while (called "aging"). the person making the wine can make different choices, which will change the flavor of the wine. they can choose to store the wine in a steel container, or a barrel made of oak wood. if they choose wood, the wine will absorb some of the wood flavor, which wine drinkers call "oakiness". this process can take only a couple of weeks, up to several years, depending on what kind of flavor the wine maker wants.
