What is crema in a coffee machine?
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. It’s formed when coffee oils emulsify with carbon dioxide under pressure. To the untrained eye, it’s a sign of freshness and quality. In truth, crema is more of a clue than a conclusion. While a silky, even crema can indicate a well-extracted espresso, it can just as easily hide a few brewing sins beneath the surface.While crema can be achieved with various coffee beans, medium to dark roasts typically produce better crema due to their higher oil content. Freshly roasted beans are also essential for optimal crema.Robusta beans, for instance, tend to produce more crema than Arabica, but the resulting crema is less aromatic and compact. Many baristas recommend a blend of Arabica and Robusta beans to achieve a balanced body and a thick crema. The roasting process also plays a role.The benefits of crema First, crema enhances the flavor and aroma of espresso coffee. Second, crema helps to preserve the freshness of espresso beans.

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. The recipe also matters.Under high pressure, the water becomes saturated with CO2 and swirls the insoluble substances in the water. This creates the finest foam bubbles. This aromatic foam eventually collects on the surface of the cup. If you add sugar to the espresso, the crema will hold it for about three seconds.His inaugural Gaggia espresso machine leveraged water and pressure, forcing hot water through ground coffee at high pressure. The result was an espresso coffee with a creamy layer called crema (Italian for “cream”).

What is the secret to good crema?
Coffee bean freshness – Freshly roasted beans retain more natural oils and gases essential for a lush crema. Grind size – A consistent, fine grind is crucial to ensure even water distribution, leading to the optimal extraction of oils necessary for the frothing process. As others have said, it’s the oils in the bean. Just like milk or cream gets its creaminess from milk fat (and skim milk doesn’t have that same quality). The variety of coffee makes a big difference. This is why Robusta beans are often added to espresso blends – they’re said to increase the crema in an espresso shot.
