The DemitasseItaly · 60–90ml · Porcelain
"Designed for a drink that shouldn't cool down."
Sixty to ninety millilitres. Thick porcelain walls. A handle so small most people pinch it between two fingers. Usually white on the inside — so you can see the crema. The saucer is mandatory. Not for drips. For the spoon, the sugar packet, and the glass of water that should come with it.
The demitasse is sized for speed. Espresso is meant to be drunk in three sips, standing, at a bar. A bigger cup would cool the coffee. A thinner wall would burn your fingers. The smallness isn't a limitation — it's the design.
In Naples, the cup is pre-heated. A cold demitasse is considered a minor insult. The barista runs hot water through it before pulling the shot. The cup should be warm before the coffee arrives.
