A long espresso, please.
LUN-go — two syllables, the 'g' is hard. Stress on the first syllable.
When you want a larger quantity of espresso with less intensity than a ristretto.
'Lungo' means 'long' — the machine pulls more water through the same amount of coffee grounds, producing a larger, slightly weaker espresso. It is still served in an espresso cup, not a large mug. It is not the same as an Americano.
Un caffè americano.
An Americano.
Espresso diluted with hot water in a large cup — popular with Northern European and American visitors
Un caffè doppio.
A double espresso.
'Doppio' = double shot — two espresso pods in one cup
Un caffè corto.
A short espresso.
'Corto' = short — less water, more intense, similar to 'ristretto'
A glass of water ('un bicchiere d'acqua') is traditionally served alongside espresso at Italian bars at no extra charge. It is meant to cleanse the palate before drinking the coffee. Always accept it — it is a mark of a quality bar.
