Demitasse

A demitasse, demi-tasse, or espresso cup is a small cup used to serve espresso. It may also refer to the coffee served in such a cup, though that usage had disappeared in France by the early 20th century.
A demitasse typically has a capacity of approximately, half the size of a full coffee cup. The Italian Espresso National Institute recommends serving espresso in a white china cup holding 50−100 ml. They are typically ceramic and accompanied by matching saucers, but some coffeehouses and china companies also produce brightly decorated varieties. Another type of demitasse has a glass cup set into a metal cup-holder frame, called a zarf in Turkey.
Demitasse cups are small because they usually serve espresso, which is a stronger, more concentrated coffee, best served in smaller portions.
A demitasse-sized cup, known as a finjan, is traditionally used for serving Turkish and Arabic coffee.
