How is a cup of coffee made? Fine Coffee Science

When we enjoy the hot cappuccino in the coffee shop, when we see the instant coffee high on the supermarket shelves, we may not expect that the coffee beans that make these coffee drinks have to go a long way and go through a lot of processing to come to us.

The equatorial region of the earth is rich in coffee trees, which have the aroma of jasmine. That's where the life of a cappuccino begins.

When we enjoy the hot cappuccino in the coffee shop, when we see the instant coffee high on the supermarket shelves, we may not expect that the coffee beans that make these coffee drinks have to go a long way and go through a lot of processing to come to us. Next, let's experience the journey of coffee beans.

The equatorial region of the earth is rich in coffee trees, which have the aroma of jasmine. That's where the life of a cappuccino begins. The so-called "coffee bean belt" includes Brazil, Vietnam and Ethiopia. The small berries of the coffee tree can be picked when they become red and yellow. The annual harvest season of coffee is related to the geographical area where it is planted. Picking coffee beans is labor-intensive because it needs to be done by hand.

About 6.3 million tons of green coffee are shipped around the world every year. Green coffee is shipped to the factory for roasting, which is crucial to the taste of the coffee. The baking process is no different from making popcorn. Beans are heated in large rollers to prevent them from being ignited until the beans jump and turn brown. After the second burst, the coffee beans will be packed and sealed and sent to supermarkets and coffee shops around the world. So far, the three-dollar cappuccino has come a long way. Along the way, it has created a lot of value, most of which is produced in baking and transportation.

A survey in 2004 showed that a Ugandan farmer was paid 14 cents per kilogram of coffee. By the time the beans are washed, roasted and packaged and appear on store shelves, they retail for $26.40.

The coffee beans are deep in the berries.

After hitting the beans, the berries are washed again and again, and eventually the whole berries will dry up. After that, the coffee beans are dried, burrowed, graded and classified.

After that, you can taste the coffee. From then on, their journey began.
