Many people like to drink coffee, like to have a cup of strong coffee in the morning, as the beginning of the day, although coffee is fragrant, but for people who do not drink coffee, no matter what kind of coffee, drink only bitter taste, why on earth will coffee have bitter taste?

There are many bitter ingredients in coffee beans. The bitter taste mainly comes from an ingredient in coffee beans called chlorogenic acid, but these bitter ingredients are actually very low in raw beans. The main source is after roasting to produce bitterness.

There are many different ingredients in coffee that make it taste different, and the main reason for its bitterness is the caffeic acid released during roasting of coffee beans, as well as the conversion of chlorogenic acid in coffee to chlorogenic acid lactone and other phenolic derivatives, which make coffee bitter.

And the longer the coffee is roasted, the more bitter the coffee will be. In addition to baking, the brewing process can also affect the taste of coffee.

The longer the brewing time, the more ingredients you extract from the coffee beans, the more bitter ingredients are extracted, and the more bitter the beans are ground, the finer the particles are ground, of course, the higher the bitterness of the coffee.

In addition, the higher the water temperature when brewing, will also increase the bitterness of coffee, although the origin and roasting degree of coffee will have different flavor, but the main impact on the taste of coffee is the various ingredients in the coffee. In fact, the taste of coffee varies from person to person. Some people prefer coffee with a strong bitter or sour taste, while others prefer coffee with a mild taste. No matter what kind of coffee it is, as long as it is suitable for their own taste, it is delicious coffee.
