It's a "Win Win" with wine carafes. One of the most profitable ways to offer wine is by the "Full Carafe", "Half Carafe", and "by the Glass"(as shown here). Offering it this way allows operators to purchase wine in larger, more economical sizes, such as 1.5 ml and 3 liter bottles and then offer it in the sizes mentioned. This will gain you a larger wine drinking audience as this "repackaging" can also offer a lower cost than "by the bottle only" menus. More customers can afford and enjoy wine, you sell more wine. Matching high quality carafes, available in 750 ml, 375 ml and 187 ml ( or 6.3 ounces, which is the standard wine glass amount). If you only want to offer wine by the bottle or by the glass, these individual glass sizes are a great way to monitor amounts.
