In some countries the use of the term "reserve", ""reserva"" or ""riserva"" is regulated, but in many places it is not. Sometimes, reserve wine originates from the best vineyards, or the best barrels, making it more special. Additionally, reserve wines may be made in a style suited to longer aging periods. However, in regions where the use is not regulated the presence of the term "reserve" on a wine label may be nothing but a marketing strategy. Indeed, in the case of one of the largest-selling premium wines, Kendall-Jackson Chardonnay, every bottle produced is "Vintner's Reserve". To indicate a traditional reserve wine, Kendall-Jackson uses the term "Grand Reserve".
