A winery is a facility where wine is produced. It typically includes vineyards, where grapes are grown, and a production area for fermenting and aging the wine. Winemakers carefully select grape varieties and monitor the fermentation process to create different types of wine, such as red, white, or rosé. Many wineries also offer tours and tastings, allowing visitors to learn about the winemaking process and sample various wines. Some wineries may have a tasting room or a restaurant, providing a complete experience for wine enthusiasts. Popular wine regions include Napa Valley and Bordeaux.
