Understanding Espresso Crema

When searching for "espresso crema," you'll find numerous explanations about that layer of fine bubbles.

The composition of crema should not be purely coffee oils, because the less coffee oil there is, the thicker the crema becomes. The common misconception that more oil equals thicker crema is incorrect. For example, Robusta coffee beans have less oil than Arabica, so the former produces more crema. Similarly, when steam extraction time is longer, there will be more crema, but this usually comes with faded coffee flavor and lighter crema color - a failed result.

The quality of crema lies not in its thickness or quantity, but in having just the right deep reddish-brown color and fine, persistent bubbles. It's typically produced during the initial phase of extraction, and crema becomes pale when extraction is excessive.

The Sensory Experience of Crema

Personally, I understand that both crema and milk foam are foam substances, each locking in the original aromatic flavors of coffee and hot milk respectively. When tasting crema alone in small sips, I find it just okay without any special feeling. However, its main attraction is that you can smell the much richer aroma even before drinking. The second key point about crema is the excellent fragrance when mixed with fine milk foam. Neither crema nor milk foam alone creates this moving experience - when mixed together, they produce an astonishing chemical reaction. The bubble texture of the first sip is simply a great enjoyment. These are experiences that convenience store coffees cannot provide.

When you drink coffee into the middle and later stages, the taste should be relatively consistent (given the same bean/milk/water ratio), but good crema and milk foam can significantly enhance 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'd 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 doesn't 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 doesn't make the mouthfeel smoother. To achieve smooth mouthfeel, the most important factor is the blend formula and ratio of beans. In terms of flavor, it will definitely be stronger, but not necessarily more bitter. Crema has finer particles, so it more easily penetrates taste buds. 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 this time, 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. Taking their commercially recommended style - commercial blend coffee beans - as an example, one 454-gram (1-pound) package costs only about 60 yuan. Calculating with 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 doesn't exceed 3 yuan. Compared to certain well-known brands that sell packages for hundreds of yuan, this is truly a conscientious recommendation.
