Coffee common sense professional coffee cup test terms

When testing a cup of coffee, we should distinguish whether the flavor, alcohol thickness, acidity and wet aroma of the coffee are pleasant. Most cup tasters use the following criteria to judge coffee.

Acidity Acidity: acidity is an essential feature of coffee, which is the feeling of dryness that coffee produces on the sublingual edge and the back palate. The effect of coffee acidity is similar to that of red wine, with a strong and exciting texture. Without enough acidity, the coffee tends to be flat. Acidity is different from sour taste, which is an unpleasant and bad taste feature. Acidity

The wet aroma is difficult to separate from the flavor. If there is no sense of smell, our basic sense of taste is only sweet, sour, salty and bitter. The wet aroma enriches the taste discrimination of the soft palate. Some subtle and delicate differences, such as the "floral" or "wine" characteristics, come from the wet aroma of brewed coffee.

Alcohol thickness is the feeling of coffee in the mouth, that is, the feeling of stickiness, thickness and richness produced by coffee acting on the tongue. The difference between drinking whole milk and drinking water is a good example. Our perception of the alcohol thickness of coffee is related to the oil and solids extracted by coffee. The alcohol thickness of Indonesian coffee is significantly higher than that of South and Central American coffee. If you are not sure about the alcohol thickness difference of several types of coffee, try adding the same amount of milk to the coffee. Coffee with high alcohol thickness will retain more flavor when diluted with milk.

Flavor is the overall feeling of coffee in the mouth. Acidity, wet aroma and alcohol thickness are all components of flavor, and it is their balance and homogenization that produce our overall sense of flavor. Here are some typical flavor features:

Rich-refers to the thickness and richness of alcohol; complexity-the feeling of multiple flavors; balance-all basic taste features are satisfactory, and no one taste masks the other.

Fresh, bright, dry, light or lively-(common in Central American coffee): caramel-like sugar or syrup; chocolate-similar to unsweetened chocolate or vanilla aftertaste; delicious-delicate flavor felt on the tip of the tongue (washed New Guinea Arabica beans); earthy-earthy aroma (typical Sumatran coffee) Fragrant-a fragrant trait, ranging from floral to spicy; fruity-an aromatic trait reminiscent of berries or oranges; sweet and mellow-round, smooth, lack of acidity; nutty-similar to the aftertaste of fried nuts; spicy-reminiscent of the flavor and aroma of various spices; sweet-unastringent Wild-a wild flavor that is generally not considered pleasant; common in Ethiopian coffee; alcoholic flavor-an aftertaste reminiscent of fully ripe wine (common in Kenyan and Yemeni coffee).

Undesirable flavor characteristics: bitter-taste from the root of the tongue, mostly caused by overbaking; boring, non-irritating-neutral; charcoal-with charred carbon; inanimate-with "Flat"; miscellaneous-moldy, reminiscent of eating dirt; earthy-with "miscellaneous" Insipid-sour, lacking wet aroma and aftertaste; grassy-reminiscent of freshly cut grass; rough-a caustic, scratched, rough quality; muddy-sticky but not strong; stiff-starch textured, similar to water cooked with pasta; rough-feel on the tongue, similar to eating salt Rubber smell-similar to burnt rubber smell (commonly found in dry processed Robusta beans); soft-same as "boring, non-irritating"; sour-similar to the acidity of unripe fruit; thin-acidity-free, usually caused by inadequate extraction; turpentine-tasting like turpentine; water-lacking alcohol thickness and no stickiness in the mouth Rough-wild quality.
