A standard carafe holds one standard size bottle of wine. However, size may vary depending on the manufacturer and the intended use of the carafe. While there is not a set capacity, a full carafe is typically 0.75 liters of wine or roughly four full glasses.
A full carafe is typically one full bottle of wine, which is standardized at 0.75 liters. One bottle of wine is usually exactly four glasses of wine. Half carafes are usually 0.375 liters and hold exactly two glasses of wine. A double carafe holds a 1.5 liter magnum bottle of wine. In restaurants, it is a common practice to provide two or four glasses of wine in the carafe based on the size of the house glassware, rather than a set amount of wine. Capacity also varies for some specialty wines, such as Sangria. These carafes are usually 1 liter but are not necessarily filled to the top during serving. Sangria glasses are also typically much smaller, meaning that there are considerably more than four glasses of wine in a full carafe. Because the exact size may vary from restaurant to restaurant, it may be a good idea to ask the waiter before ordering a carafe of wine.
