Finished wines, reviewed from bottle in blind tastings, are given a single score. For some types of wines, such as Bordeaux, which is sold as futures, Wine Spectator tastes barrel samples of unfinished wines. In these cases, the wine’s rating is listed as BT, along with a score range (e.g., 90-94), signifying that it is a preliminary score that indicates the wine’s future potential when it is finished. Most barrel tastings are blind; when they are not blind, this is specifically noted.
