Old fashioned glass

The Old-Fashioned glass, rocks glass, or "lowball", is a short tumbler used for serving liquor "on the rocks", meaning over ice, or cocktails having few ingredients. It is named after the Old fashioned cocktail, traditionally served in such a glass. A White Russian is traditionally served in the Old Fashioned Glass.

Contemporary American "Old-Fashioned" and "rocks" glasses may hold as much as 8-12 fluid ounces (22-34 cL), and may be used to serve a wide variety of beverages over ice, such as whisky. However, it is quite common to see old-fashioned glasses holding significantly less than 8 ounces. A "double old-fashioned" is often considered to hold 12 ounces.
