Drinking coffee can be said to be indispensable in people's lives now. People can be seen holding coffee cups in the morning, afternoon or evening. The following is the basic introduction of black coffee I shared. Let's have a look.

fragrance

Black coffee emphasizes the aroma of coffee itself. Aroma is the life of coffee quality, which can best express the making process and baking technology of coffee. The climate, variety, refining treatment, harvesting, storage and baking technology of the consuming country are all conditions that determine the aroma of coffee beans. Bitterness is the basic taste of black coffee, and its strength and texture are different. Raw beans only contain a very small amount of bitter ingredients, and then the most symbolic bitter taste of coffee is produced by caramelization and carbonization of sugar, starch and fiber caused by baking.

Black coffee also has a sour taste. Proper heating will produce moderate acidity, which will make coffee taste better and make people feel deeper. The sweetness of black coffee is closely related to the bitterness, so refreshing and superior black coffee tastes sweet.

We are familiar with Yunnan coffee, Blue Mountain, Mantening, Huju, Brazil and charcoal, which can be bought in many supermarkets, and most of them are baked beans.

Due to different producing areas, the characteristics of coffee beans are different, some of which are darker in color, higher in baking degree and stronger in taste; Some are lighter in color and slightly lighter in taste. Experts choose coffee, mostly by grabbing a handful of coffee beans to see whether the color of each bean is consistent and whether the particle size and shape are similar, so as to avoid buying inferior products disguised as mixed beans. In addition, if the baked beans are oily, it means that they have gone bad, not only the mellow degree is reduced, but also the astringency and sour taste will appear.
