A winery is a building or property that produces wine, or a business involved in the production of wine, such as a wine company. Some wine companies own many wineries. Besides wine making equipment, larger wineries may also feature warehouses, bottling lines, laboratories, and large expanses of tanks known as tank farms. Wineries may have existed as long as 8,000 years ago.Wineries typically employ winemakers to produce various wines from grapes by following the winemaking process. This process involves the fermentation of fruit, as well as blending and aging of the juice. The grapes may be from vineyards owned by the winery or may be brought in from other locations. Many wineries also give tours and have cellar doors or tasting rooms where customers can taste wines before they make a purchase. Winery architecture is very varied and rich and it is used by wineries as a way to promote their wines and cellar doors.
