The impression that a wine leaves in your mouth even after you have swallowed it. A finish may be almost nonexistent, fairly short, or extremely long. It may be smooth and lingering, or rough and choppy. A finish may also be dominated by one component in the wine, such as ALCOHOL (a HOT finish), ACID (a tart finish), or TANNIN (an ASTRINGENT finish). A great wine, as opposed to a good wine, always has a pronounced, very long, lingering, well-balanced finish. In some judgings, officials actually measure the length of time that the wine can still be tasted after it has been swallowed.
