How to taste coffee? How can you tell if coffee is good or bad?

Coffee tasting is generally about tasting two or three coffees at a time and then comparing them based on their smell, acidity, body and taste. Of course, when tasting coffee, you must start with a coffee with a relatively low body content. First of all, the smell, and then the taste, pay attention to the acidity and body of the coffee.

Acidity The acidity in coffee is not a degree of sourness or bitterness, but a lively, intense, and fresh degree of flavor. Body is the weight or density of a drink. The taste is a combination of the above three to make an impression.

It may be difficult to understand just by saying this, but the main thing is to drink more and pay attention to comparison, and then exchange ideas with friends around you who also love coffee, such a process is both interesting and learn how to taste.

The steps to taste coffee are as follows:

1. Smell the fragrance, high-quality coffee is fragrant;

2. Looking at the color, the high-quality coffee is dark brown;

There are two ways to tell if coffee is good or bad:

1. Identification before brewing:

Good quality coffee is brown to dark brown, and the tissue state is about 2 mm in size, mixed with some aromas unique to fine powder coffee.

Inferior coffee has a dark or iron-black color. The tissue state has the phenomenon of clumping and clumping. The roasted aroma of the coffee is light or absent, replaced by a strong burnt taste.

2. Identification after brewing:

Good quality coffee dissolves completely, free of dross and suspended solids. The soup is brownish-red and bright, with a strong coffee aroma. After adding sugar, it has a moderate bitter and sour taste, and the flavor is straightforward.

After the inferior coffee is dissolved, there is sediment at the bottom of the cup, and the color of the soup is dark and brownish-black. The aroma is light and the burnt taste is strong. After adding sugar, the bitterness and sourness are strong, and the aftertaste is bitter.

Because coffee contains caffeine, it has the effect of stimulating the central nervous system of the brain, which can refresh and awaken after drinking, eliminate fatigue and drowsiness, and improve work efficiency. Coffee has a unique aroma and color, giving people the enjoyment of color, aroma and taste. Therefore, coffee is deeply loved by the masses and has become one of the main beverages in people's daily life.

1. Smell the fragrance. The coffee should be able to feel its full-bodied aroma in both the bean and powder state, and the aroma will be further stimulated during the extraction process due to contact with hot water. However, it should be noted that the smell must be hot, as the temperature drop or iced coffee will make the aroma quite closed.

Natural floral and fruity aromas are naturally the best enjoyment, and if you smell the flavor of the coffee itself, then you should be wary, which may be a trick to cover up the poor quality of the coffee itself.

2. Taste. The bitterness of coffee is the most representative flavor and the most sensitive taste sensation of people. It's a substance in coffee called chlorogenic lactone, which increases with the degree of roasting of the coffee, which is why dark roasted coffee is especially bitter.

It's not that the bitterer is better or worse, on the one hand, it has to suit your taste, and on the other hand, the good bitterness can blend with the sourness and sweetness to form the perfect Daigo taste. The coarser bitterness is very straight, as if taking Chinese medicine.
