vaahdottaja

Vaahdottaja is a Finnish noun that denotes an agent or device that produces foam by introducing air into a liquid. In everyday language, it can refer to a person who foams milk or other liquids, or to a machine that performs the foaming action.

The word is formed from vaahdota "to foam" and the agentive suffix -ttaja, yielding "one who foams." The term is neutral and its meaning depends on context; it can describe a person (a barista, home cook) or a piece of equipment such as a frother.

In culinary and beverage contexts, a vaahdottaja may be a barista or home enthusiast who foams milk for cappuccinos, lattes, or hot chocolate, using tools such as a steam wand, whisk, or electric frother. In industrial food processing, the term can signify equipment designed to create stable foam, for example in dairy processing or product finishing.

In product descriptions, vaahdottaja is sometimes used as a generic name for foam-making devices, though more specific terms like maidonvaahdotin or vaahdotin are common. See also vaahdotus, vaahdottaminen, maidonvaahdotin.
