Yes, in winespeak, cigar box is an adjective, used to describe wine that has a cedarwood aroma, since all fine cigar boxes are made with Spanish cedarwood. The term can also be used for a wine that has the fragrance of cigar tobacco (that heavenly aroma that comes from opening a well-stocked cigar box). The descriptor is often applied to Cabernet Sauvignon, particularly those from Bordeaux.
