Today, 7 Coffee will take you to discuss how a good cup of coffee is made.

First order: planting

Coffee trees are suitable for planting in tropical and subtropical areas. The coffee we drink every day is baked from coffee beans grown on coffee trees. The types of coffee trees in the world are Arabica and Robusta, and different growing environments often give coffee different characteristics. Arabica grows best at high altitudes, while Robusta grows at low elevations.

Second order: select

Coffee beans are berries that are often red when ripe. Like wine grapes, the choice of coffee beans is also important. First of all, the seeds are extracted from the picked coffee fruit, and then the raw coffee beans are processed, which is the "selection" in the coffee process. Then remove the pulp and endocarp, which is called "refinement". After that, the coffee beans are classified and the ones of poor quality are singled out. This is the so-called "selection". Then generally use the sun or water washing method, and after a certain degree of fermentation treatment, in order to get sweet and sour delicious, rich taste of good beans. After these processes, the raw coffee beans are sealed in bags and sold all over the world.

Sequence 3: baking

After buying coffee beans, the baker will roast and mix them, which is the most important and critical process! The roasting time of coffee beans is generally not long, about 8-16 minutes. In the roasting process, coffee beans will go through a series of complex chemical changes, their color and size are very different from raw beans, but also emit an attractive aroma that originally did not have. According to the degree of baking, it is generally divided into shallow baking and deep baking. Shallow baking can better reflect the original flavor of beans, which tastes sweet and floral, while deep baking takes longer and tastes bitter and sweet.

Fourth order: grinding

After the coffee beans are roasted, they are ready to drink and can be sold directly or further ground. Generally speaking, coffee beans can be ground in a manual bean grinder or an electric motor, and after being developed into a powder, it is our common coffee powder.

Fifth order: brewing

Water-flushing coffee is to put coffee powder into an extraction vessel and extract it with normal temperature water instead of hot water. The coffee obtained in this way tastes mild, without strong bitterness and aroma. Of course, you can also carry out home-style simple extraction, add coffee powder and cold water to the coffee cup, and then extract it with a simple extraction device, so that a cup of strong coffee is ready!

The training of a good cup of coffee has to go through many processes such as planting, selection, roasting, grinding and brewing, which is complicated but not miscellaneous, condensing the essence of coffee and tasting life. In every small coffee shop, every cup of coffee is carefully brewed by the barista, so pick a sunny afternoon, put down the instant coffee, and have 7 coffees and a good cup of coffee.
