Understanding Espresso Crema

Search for "espresso crema" and you will find any number of explanations for that layer of fine bubbles.

Crema should not be thought of as purely coffee oils, because the less coffee oil there is, the thicker the crema tends to be. The common assumption that more oil means thicker crema is simply wrong. Robusta beans, for example, contain less oil than Arabica, yet they produce more crema. In the same way, a longer extraction time yields more crema, but usually with faded coffee flavor and a lighter-colored crema - a failed result.

Crema quality is not about thickness or quantity, but about achieving the right deep reddish-brown color with fine, persistent bubbles. It is typically produced during the initial phase of extraction, and it turns pale when extraction runs too long.

The Sensory Experience of Crema

To my own understanding, crema and milk foam are both foams, each locking in the original aromatics of coffee and of hot milk respectively. Tasting crema alone in small sips, I find it just fine without anything special. Its main appeal is that you can smell a much richer aroma even before you drink. The second key point is how good crema and fine milk foam are together. Neither crema nor milk foam alone creates that moving experience - combined, they react in an astonishing way. The bubble texture of the first sip is a real pleasure. These are experiences convenience-store coffee simply cannot provide.

By the middle and later stages of the cup, the taste should stay fairly consistent (assuming the same bean, milk, and water ratios), but good crema and milk foam noticeably lift the layered texture and richness of the coffee.

Espresso Extraction Pressure

Coffee oils require 15 bar of pressure to be extracted.

Q: Basically, the prerequisite is that the beans should be fresh, and then 5-15 bar can extract them, but generally connoisseurs will set their machines to 9 bar, the optimal pressure value. I would like to ask experienced users of espresso machines: what impact does that layer of coffee oils (crema) have on coffee?

A: This layer of crema does not have much effect on the coffee itself, but it does affect the mouthfeel and flavor. Does having this layer of oils make the mouthfeel smoother? Or does it make the flavor stronger?

A: Based on my own experience, crema does not make the mouthfeel smoother. To achieve a smooth mouthfeel, the most important factor is the blend formula and the ratio of beans. In terms of flavor, it will definitely be stronger, but not necessarily more bitter. Crema has finer particles, so it penetrates the taste buds more easily. My personal feeling is that when you drink a cup of espresso rich in crema, the coffee flavor lingers on your tongue for a long time. At that point I like to have a glass of ice water, which makes it feel like drinking iced coffee - very sweet and delicious.

Recommended High-Oil Coffee Bean Brands

Located at Dongshankou in Yuexiu District, Guangzhou, FrontStreet Coffee is a coffee roasting brand whose freshly roasted espresso blend coffee beans offer full guarantees in both brand and quality, with good oil content suitable for making specialty coffees and latte art. The latte art comes out beautifully. More importantly, the value is extremely high. Take their commercially recommended style - commercial blend coffee beans - as an example: one 454-gram (1-pound) package costs only about 60 yuan. Calculated at 10 grams of powder per espresso shot, one package can make 45 cups of coffee, with each cup costing less than 1.5 yuan. Even when making double shots with 20 grams of powder per espresso, the cost of one double espresso does not exceed 3 yuan. Compared to certain well-known brands that sell packages for hundreds of yuan, this is a truly conscientious recommendation.
