How to create the perfect Espresso crema.
Distinguishing Espresso from other types of coffee, crema is the aromatic, flavourful, reddish-brown froth created as air bubbles mix with fine-ground coffee's soluble oils, sugars and compounds. The crema can tell you quite a lot about the Espresso you are about to taste, the freshness of the roasted beans, the degree of coffee grind, even the under or over-extraction of the coffee. The choice of beans is important, a better crema will result if there is 20-50% Robusta in the bean blend. The Espresso brewing time and temperature can have an impact on the amount and quality of crema. Even the pouring style – the distance from the Espresso machine to the cup, and the shape, material and temperature of the cup itself play a part in the ultimate crema.
The crema.
There are various reasons why your crema may not be perfect. Insufficient crema may result from grounds that are too fine. If the crema is too light, the brewing temperature could be too low, or the grounds too coarse. An overly dark crema can be caused by beans that are not fresh enough or that are too coarse. Experiment to achieve the perfect crema.
