What are crema coffee beans?
Crema is the creamy, reddish-golden froth on the top of your espresso shot. Not only does it look inviting, it’s full of flavour, texture and aromas. This beautiful foam layer appears when hot water is forced through the coffee grounds at high pressure, emulsifying the coffee bean oils and forming tiny, smooth bubbles. For there to be a good layer of crema on the espresso, the coffee must be emulsified at the right temperature and pressure. Extraction time is also key; making a coffee in twenty seconds or in more than thirty seconds will influence the quality and existence of the crema.Achieving the right grind size and tamping pressure is essential for perfect espresso crema.
