About connoisseur

A connoisseur is a person who has a great deal of knowledge about the fine arts; who is a keen appreciator of cuisines, fine wines, and other gourmet products; or who is an expert judge in matters of taste. In many areas, the term now has an air of pretension, and may be used in a partly ironic sense. In the art trade, however, expert connoisseurship remains a crucial skill for the identification and attribution to individual artists of works by the style and technique, where documentary evidence of provenance is lacking. The situation in the wine trade is similar, for example in assessing the potential for ageing in a young wine through wine tasting.
