A perfectly brewed cup of espresso includes a top layer called crema — a golden - brown foam, usually obtained with difficulty, that adds smoothness and holds in some of the aroma.
Õigesti valmistatud espresso pinnal on kiht, mida nimetatakse crema’ks — see on kuldpruun vaht, mis pole tavaliselt sugugi kerge tekkima ning mis lisab mahedust ja aitab säilitada aroomi.
