The words "Private Reserve" on a label supposedly indicate that this is a limited production of the winery's best wine, such as Beaulieu Vineyard Private Reserve. If you think about it, however, it's a bit of an oxymoron, because if this is the winery's private stuff, why are they selling it to you? Since there is no legal definition of a Private Reserve, even wineries of questionable repute can slap the words on their label (and they often do). In most cases, however, a reputable winery that markets their premier wine as a Private Reserve is offering you their finest stock, and charging accordingly. Spin-offs of the term include Proprietors Reserve, Signature Reserve, and—more often than not—simply Reserve.
