Some wines are classified by their varietal, which is the type of grape used to make the wine. Varietal wines can be SWEET, oaky, ROSE, semidry, DRY, AGED, RED, or SEC. SWEET wines are those with a higher sugar content, while oaky wines have been AGED in oak barrels, giving them a distinct flavor. ROSE wines are made from RED grapes, but are lighter in color and body than RED wines. Semidry wines are slightly sweeter than DRY wines, which have almost no residual sugar. AGED wines have been stored for a long period of time, often in oak barrels, and can have a more complex flavor. RED wines are made from RED grapes, and SEC wines are very DRY.
