The skill of foaming coffee

The skill of foaming coffee

(1) when dispelling foam, the choice of milk is also very important. the wrong choice of milk will lead to rough foam, rapid rupture, and even no foam at all. (2) the principle of dispelling foam is very similar to that of whipping cream, that is, by injecting air into the milk to increase the contact area between the milk surface and the air, so that as much air as possible is wrapped in the structure of protein-supported fat balls.

Why does Fine Coffee emphasize freshly ground Coffee

Why does Fine Coffee emphasize freshly ground Coffee

If the diameter of the coffee powder is doubled, the volume of a single particle is reduced by 1 × 8, and the surface area of the corresponding total coffee powder is doubled. After the coffee bean is ground into coffee powder, its surface area increases exponentially, and the area of contact with air increases hundreds of times. The extremely important acidic and volatile fats in roasted coffee beans once exposed to air

Scientists find genes that determine the quality of coffee

In order to earn more income, coffee growers have been committed to producing higher quality products. But getting high-quality coffee beans means a better understanding of biological processes such as flowering and ripening that determine the final quality of the product. Many compounds (sugar, fat, caffeine, etc.) determine the quality of coffee. Their content in coffee beans is the decisive factor. In which sucrose

Analysis of coffee composition where does the bitterness in coffee come from

A cup of coffee is a complex drink made up of more than 30 chemicals that determine the taste, aroma and acidity of the coffee. Since the 1930s, scientists have isolated and identified a variety of chemicals related to the sensory composition of coffee, but no one can figure out what makes coffee so bitter. In order to solve this mystery, science has to cook.

Hand coffee extraction time hand coffee bitter boutique coffee producing area single coffee

Hand brewing and racing wind, the longer the brewing time, the higher the concentration, but many hand brewers do not have the concept of time. Haohao brews a cup of coffee with a large amount of water in less than a minute. Such hand brewed coffee will not have a delicate taste spectrum. Drinking is weak and lifeless, Baiwei is uneven, and even acidity hinders the mouth, which is caused by insufficient extraction, and a lot of coffee essence still remains in the coffee grounds. On the contrary

Why does coffee need fresh grinding?

When you smell the fragrance of coffee powder, it shows that it is deteriorating and the essence of coffee is decreasing. If the diameter of the coffee powder is doubled, the volume of a single particle is reduced by 1 × 8, and the surface area of the corresponding total coffee powder is doubled. After the coffee bean is ground into coffee powder, its surface area increases exponentially, and the area of contact with air increases hundreds of times.

Scientists find genes that determine the quality of coffee

Many compounds (sugar, fat, caffeine, etc.) determine the quality of coffee. Their content in coffee beans is a matter of sexual identity. Among them, sucrose plays the most important role in the sensory quality of coffee, because the differentiation of sucrose in the roasting process will produce a variety of aromas and other tastes. In order to earn more income, coffee growers have always been committed to producing higher quality products. But

Coffee training knowledge: why emphasize freshly ground coffee

Coffee training knowledge: why emphasize freshly ground coffee

Why emphasize freshly ground coffee? When you smell coffee powder, it indicates that it is deteriorating and the essence of coffee is decreasing. If the diameter of coffee powder is doubled, the volume of individual particles is reduced by 1/8, and the surface area of the total coffee powder is doubled accordingly. After coffee beans are ground into coffee powder, its surface area increases exponentially, the area in contact with air.
