When evaluating a cup of coffee, we use various adjectives to describe the texture, so that the information received by others can be more three-dimensional. For example, when describing the taste of coffee, we use words such as smooth and mellow to express the tactile experience of coffee in the mouth; or when describing the aroma of a cup of coffee, we use words such as rich, light and fresh to express the type of aroma.

However, not all adjectives are so easy to understand. For example, among the adjectives describing coffee acidity, there are puzzling words such as "bright" and "lively." So today, the front street will share what often appears in the mouth of the barista: "The acidity of this cup of coffee is very bright." What does "bright" mean?

Putting aside the word "bright" first, Qianjie will first show you the meaning of "acid". Because even though Qianjie has shared many articles, friends often confuse "acidity" with "acidity". First of all, we need to know that acidity does not equal acidity. The word "acidity" describes the strength and amount of acid; while "acidity" refers to the acidic style and texture. It includes not only the intensity of the taste, but also other sensory experiences that can be combined with the taste, such as taste, aroma, but the main body is acid. To put it more easily, it is whether the acid is comfortable and whether it makes people feel happy.

The acidity of coffee is affected by many aspects, such as variety, planting, processing, and roasting (interested friends can search past tweets, and I won't go into it here), so the acidity of different coffees is different. Good acid can make people feel comfortable and happy, while bad acid can make people frown and be difficult to accept. You can recall the different feelings you had when exposed to various sour drinks! For example, for yogurt (sweetened), the acid we feel from yogurt is very mild, and it will also have obvious milky aroma and thick taste when drunk, giving people a very comfortable feeling. Then combining the taste, aroma, and taste, we can define the sour texture/style of yogurt as pleasant: round, and the round acid in coffee is the same; and if the acid we drink from coffee is like sour fruit is rotten, which makes people feel very unpleasant, very sharp and uncomfortable, then we can define its sour texture/style as: sharp/stimulating. In summary. The question arises, what kind of feeling does "brightness" in bright acid mean?

Very simple! The literal meaning of "bright" is usually based on visual perception, which refers to visual experiences such as abundant light and transparent space, or high definition, high visibility, and vivid colors that can bring open, pleasant, and positive psychological feelings. When it is used as an adjective for taste, the meaning it expresses is similar to the feeling brought by vision, but it is divorced from its own physical meaning of light. Simply put,"bright acid" means to describe that the acid of a cup of coffee is very clean, very clear, and highly recognizable, which can bring a psychological feeling of vitality and pleasure. (It's not just coffee that can be used to describe)

Usually, the taste characteristic of this acid is high acidity, so it can be recognized enough. However, this acid is not as stimulating as drinking vinegar alone, because there is enough sweetness behind it. Just like lemonade with sugar, it will be much more acceptable than freshly squeezed lemon juice without adding anything. Therefore, it can also be understood that the taste of this cup of coffee will have a relatively high balance. Secondly, this cup of coffee will have a relatively high cleanliness! The flavor is not turbid or ambiguous. Because the coffee itself does not contain any impurities, the acid/flavor of the coffee is clear and transparent. In addition, the "bright" acidity also symbolizes the fresh type of coffee aroma. Because only a non-dull and non-oppressive aroma can make us feel "vitality" and "pleasure". Finally, there is the taste. Only when the taste of coffee is not so thick and light, can the acidity be labeled as a "bright" style.

When we think that the acid of a cup of coffee is bright, we usually associate it with citrus fruits such as lemon, citrus, and grapefruit, or other fruit flavors such as raspberry, blackcurrant, and pineapple. To borrow the words of a netizen on the Internet, it is the kind of fruit type (not all) that will pop when you take a bite and then you can feel fresh and sour. We can often capture this flavor type, or bright acidity, in coffee from Ethiopia, Kenya, Panama, Colombia and other regions. So if you also want to feel the bright acid from coffee, you may wish to try coffee from these producing areas. For example, Kenya Assalia, Ethiopia Eto, Jade Manor and Diamond Mountain in Qianjie Doudou List are all very good choices~
