Tumbler (glass)

A tumbler is a flat-floored beverage container usually made of plastic, glass or stainless steel.

[citation needed] Originally, the term tumbler referred to a type of drinking glass with a pointed or rounded base, which prevented it from being put down until it was empty, encouraging the drinker to finish their beverage in one go.

[citation needed] Over time, the design evolved into the flat-bottomed glassware we are familiar with today, which can comfortably sit on tables and counters without tipping over.

[citation needed] The modern tumbler comes in various sizes and shapes, designed to accommodate a wide range of beverages from water and juice to sophisticated cocktails.

British cookery books and recipes, especially those from the days before the UK’s partial metrication, commonly use two or more of the aforesaid units simultaneously: for example, the same recipe may call for a ‘tumblerful’ of one ingredient and a ‘wineglassful’ of another one; or a ‘breakfastcupful’ or ‘cupful’ of one ingredient, a ‘teacupful’ of a second one, and a ‘coffeecupful’ of a third one.
