Tumbler / Old Fashioned glass
Tumbler' is a collective term for various forms of bar glasses; however, the term is widely used as a synonym for Old-Fashioned glasses - these are short glasses with a thick bottom made of solid glass (bottom ice) and a volume of approx. 18-30 cl. This base was originally rounded, as in some cognac snifters, so that the glasses fell over when they were put down - this earned them their nickname tumbler.
Old Fashioned glasses, on the other hand, take their name from the traditional whiskey cocktail Old Fashioned. However, since they are often used for pure whiskey or whiskey on the rocks, they are also referred to as whiskey glasses or rocks glasses. In distinction to higher Highball or Collins glasses, they are sometimes found under the designation Lowball.
Large Old-Fashioned glasses with a volume from about 350ml are called Double-Old-Fashioned glasses (DOF or D.O.F. for short).
Whisky tumblers or Old-Fashioned glasses fit well in the hand thanks to their compact size and are considered versatile and stable glasses, which belong to the standard repertoire of every bar. Besides whiskey, they are used for cocktails such as Negronis, but also for soft drinks such as juice or coke. The thick base as a low center of gravity ensures that the glass is stable and does not tip over easily; if the glass is pre-cooled, the base ice acts as an additional cold dispenser, which cools the drink and thus also counteracts its dilution.
However, since tumbler is a collective term for almost all forms of bar glasses, the following glasses also fall into this category:
