Question: what is the difference between espresso and demitasse?
Answer: An espresso cup is more correctly called a “demitasse.” Demitasse simply means “half-cup” in French, and it typically holds between 2 and 3-fluid ounces of liquid. A doppio normale (that's Italian), refers to a cup that holds about 2-fluid ounces of liquid. A lungo (large) doppio takes up to 3-fluid ounces.
