Why can you feel a little sweetness when tasting black coffee?

Most people only taste bitter, sour and astringent coffee. In fact, raw coffee beans contain about 50.8% sugar. After baking at high temperature, most of the sugar will be converted into caramel. This caramel effect brings a unique tea brown to the coffee, forming a source of aroma and bitterness, while the remaining sugar leaves some sweetness. In addition, the tannic acid released when roasting good coffee beans, combined with the formation of brown caramel, will also produce a slightly bitter sweetness.

Why do some coffees taste sour?

Whether coffee tastes sour is mostly due to the variety of coffee, some of which have high acidity, such as Kenya, Mocha, Colombia, Guatemala and Costa Rica.

The degree of roasting is also related to the acidity of the coffee, usually the lightly fried coffee beans also contain organic acids, so the coffee washed out tastes sour, while the deep-fried coffee beans, because the high temperature of the fried beans has released the organic acids contained in the coffee beans, so the acidity of the coffee is low. The reason why the coffee will be sour is that the coffee is stirred too many times during brewing or the brewed coffee stays on the heat preservation plate for too long.
