If you have bought fresh coffee and ripe beans, you can smell it when you open the package, but when you smell the coffee, it shows that it is volatilizing and the essence of the coffee is decreasing. If the diameter of coffee is doubled, the volume of single particle is reduced by 1 / 8, and the surface area of the corresponding total coffee powder is doubled.

Learning essentials of SCAA Coffee Flavor Wheel the origin of coffee flavor wheel

Coffee has only four kinds of water-soluble tastes: sour, sweet, bitter and salty, some sour and sweet, only volatile, which need to be identified by smell; some are non-volatile, only water-soluble, and need to be identified by taste buds; and some sweet and sour ingredients are both volatile and water-soluble, so sour and sweet often show the dual senses of smell and taste. As for bitterness and saltiness, there is no volatility.

The truth that ordinary coffee makers don't want to tell.

The truth that ordinary coffee makers don't want to tell.

The basic ingredients of a good cup of coffee are freshly roasted beans. Once the coffee beans are roasted, the extremely important acidic fat and volatile fat in the coffee beans will change chemically once they come into contact with the air. The esters and aldolases in the aromatic compounds of coffee are the most volatile, which will worsen the taste of coffee. It's not just the volatilization of aromatic substances.

According to the source, the aromatization table can be divided into three groups: the first group: this kind of compound is the result of enzymatic reaction during the growth of coffee beans. The main components are ester and aldolase. This compound is the most volatile and is often found in the dry aroma of freshly ground coffee powder. The first group can be further subdivided into three types: floral flavor, fruit flavor and

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
