What can be regarded as the real "coffee burning"?

The mural under the light

Coffee beans in cafes are usually roasted cooked beans, because selecting beans is one process, and roasting is another subject. "if the roasting heat of coffee beans is small, the fruit acid will be more abundant, and the heat will be more bitter." In addition, "baking is a magical science, and it takes years of practice to realize the nuances." The mellow aroma of freshly ground coffee is not available in other coffee drinks. "every customer has the right to hear the sound of grinding beans of their own coffee. Each cup of coffee should be ground freshly, and the oxidation of the ground coffee powder will affect the taste. "

Individual coffee can best reflect a person's ability to drink coffee. "Mantenin coffee is bitter and smelly, with almost no sour taste; Colombian premium coffee contains sour fruit, and slow coffee can taste slightly nutty; Ethiopian coffee can smell obvious citrus aroma when grinding beans and lemon when finished; Kenyan coffee is similar to red wine acid and plum acid. Mocha coffee is a kind of Yemeni coffee, because the coffee tree and cocoa tree are relatively close, so it has a slightly cocoa flavor. Panamanian rosy summer can also be called geisha coffee because its English pronunciation is the same as that of Japanese geisha. The acidity is very obvious, with a sour taste of grapefruit. " Some people use the term "coffee entrance, flowers in full bloom" to describe a cup of gourmet coffee. The difference in the smell of flowers can be regarded as a real "coffee burn".
