Length is essentially, as it implies, a measure. A wine's length may be described as long, moderate or short. In general, a long length is considered a sign of high quality.
A wine's length differs from its finish (although the terms are often used interchangeably), in that, in my opinion, the finish is a more of a descriptive term. It describes the very last flavor or textural sensation left in your mouth after swallowing or spitting the wine. Terms I use to describe the finish of a wine include spicy, minerality, savory, sweet, bitter, hot, harsh, rich and so forth - essentially the same adjectives that you might use to describe flavor or texture of a wine.
