What are the flavors of coffee beans?

First, aroma-the most fascinating thing about coffee is its pungent aroma, which will change into a complex aroma after light and high heat treatment of fat.

Second, flavor-caffeine (Coffeein), tannic acid, sugar and other comprehensive.

Third, sour taste-an organic acid from the fruit, acidity is inversely proportional to heat.

Fourth, bitterness-caffeine (Coffeein), sugar, fiber and so on are formed by high heat mussel.

Fifth, sweet taste-0.4-1.9% of the sugar left after baking is sweet in addition to fragrance and bitterness, and good tannins also have sweet taste.
