Six steps of coffee tasting General knowledge of fine coffee
Coffee tasting has six steps to describe the aroma, aroma, taste, smell, aftertaste and mellowness of coffee.
1. Fragrance: the first step in tasting is to evaluate the aroma of coffee beans. Grind 8.25 grams of coffee, put it in 3-5 sample cups, and then breathe hard at the gas released by the freshly crushed coffee cells.
The characteristics of the aroma indicate the essence of the taste of coffee beans: the sweet smell indicates that its taste is sour; the pungent smell indicates that its taste is irritating. The strength of the aroma indicates the freshness of the coffee, that is, the time it takes from roasting to grinding into powder.
The aroma consists of the most volatile aromatic compounds, especially those containing sulfur, such as methyl mercaptan. At present, there is little people can do about how to keep these substances in coffee beans.
two。 Aroma: the second step in tasting is to check the aroma of coffee water. First, pour 150ml of boiled fresh (oxidized) water into the freshly ground coffee powder and let the coffee powder soak in water for 3-5 minutes. Coffee powder forms a cap-shaped shell on top of the water.
Stir the coffee with a coffee spoon and break the cap shell. At this time, the caffeine hot water will release the gas into the nasal cavity, so that the nasal diaphragm feel a comprehensive flavor: from fruit, grass, to nutty. The experience of tasting will cause the tasters to classify coffee according to the memory of various coffee smells. In the future, different kinds of coffee can be distinguished according to different odors.
Generally speaking, the aroma characteristics of coffee are related to the origin of coffee. Correspondingly, the strength of the aroma is related to the freshness of coffee. Freshness is measured by the length of time from baking to cooking. Freshness is also affected by the type of packaging that protects coffee from dampness and non-oxidation.
3. Taste (Taste): carefully savoring the taste of freshly brewed coffee is the third step in tasting coffee. Use a special coffee spoon, usually a round spoon with a capacity of 8 ~ 10cc. Preferably silver-plated, which can dissipate heat quickly. Take out 6 ~ 8cc of coffee water and put it in front of your mouth and sip it hard. Quickly inhale coffee and distribute it evenly on the surface of the tongue. All sensory nerve terminals respond to sweet, salty, sour and bitter tastes at the same time.
Because temperature affects the degree of stimulation, paying attention to responses in different sensitive areas of the tongue can help capture different characteristics. For example, because temperature reduces sensitivity to the sweetness of sugar, acidic coffee initially produces a tingling on the tip of the tongue rather than sweetness. Hold the coffee in your mouth for 3-5 seconds and focus on the type and intensity of the taste. In this way, primary and secondary flavor characteristics can be evaluated.
4. Nose: the fourth step is the same as the third step. Inhale coffee through the surface of the tongue. Due to the change of water vapor pressure, part of the organic matter in the water changes from liquid to gaseous state. The act of sucking coffee hard causes the gas to enter the nasal cavity, allowing the tasters to analyze the smell of the coffee.
At the same time, evaluate the taste and smell of coffee, so that tasters feel the unique taste (flavor) characteristics of coffee. Standard roasted coffee usually has the taste of caramelized products, while deep-roasted coffee usually has the taste of dry distillation products.
5. Aftertaste (Aftertaste): the fifth step is to put coffee water in your mouth for a few seconds, then swallow a small part. Quickly suck the throat to send the water vapor left in the back palate into the nasal cavity, you can find the smell of the heavier molecules left in the back palate.
The aromas of various compounds felt in the aftertaste are sweet, similar to chocolate; or bonfire smoke, or cigar smoke; sometimes, there are similar irritating spices, such as cloves; sometimes, like resin, similar to turpentine; sometimes, there are all these smells.
6. Body: the final stage of tasting is to evaluate the taste of coffee water. The tongue slips gently across the palate of the mouth to feel the texture of the coffee. The feeling of oily quality and smoothness can measure the fat content of coffee water, while the feeling of "weight", thickness and stickiness of coffee can measure the fiber and protein content of coffee. The two make up the mellowness of coffee.

The tall cup is a perfect match with the thick milk foam. Use a tall cup to give you enough time to merge. Full fusion can not only make the coffee taste better, but also strengthen the shape when pulling flowers, resulting in a clear drawing of eucalyptus. But the prerequisite is that the foam should be sufficient. Some people will only pour hot milk into the cup before forming and keep the foam until the end for flower drawing.
