Many people like to choose a cafe on rainy days, pick a quiet seat, close your eyes and put on headphones, order a cup of coffee, quietly feel the moisture in the rain; and want to get a cup of warm coffee, but also take time to wait for production, this world,"and so on" the most difficult to master, you know in waiting for coffee production during this period of time, it has experienced what life journey?

Everything has its birth, growth, maturity, Wanda life process, coffee is no exception.

growth

Coffee berries grow on coffee trees. It likes mild temperatures, not too hot, just like infants and toddlers, who need "umbrellas" to protect them from direct sunlight. As the home of the world's coffee, Ethiopia's varied alpine climate is ideal for growing coffee trees and producing Arabica beans.

After 6-8 months of growth, coffee beans into maturity, coat from green to red, very beautiful.

picking

Coffee beans are usually harvested in two ways. One is to pick in pieces, all the beans are picked at once, one is to pick selectively, that is, at intervals of 8 to 15 days, only ripe red berries, selective picking is more expensive than picking in pieces, the largest amount of labor, generally only used for Arabica coffee beans.

How many stops does the coffee bean have on its journey to life?

green bean treatment

Generally speaking, there are three ways to treat raw beans: sun method, washing method and mixing method. Different ways directly affect the final flavor of coffee.

Sunlight method: coffee fruit after sun drying peel removed, and the consequences of close contact with nature is to absorb a lot of different flavors, both floral fruit flavor, there will be soil flavor, to ensure that the original flavor has an impact.

Washing method: after taking out the pulp, wash it repeatedly with water to remove impurities on the surface of the raw beans, which will increase the acidity.

Mixing method: including honey treatment method, semi-water treatment method, etc., these will enhance coffee concentration, acidity, richness to varying degrees.

baking

More than 80% of coffee taste depends on roasting, this stage is also an important turning point of coffee from green beans to mature beans, generally speaking, when the season beans freshly roasted by the taste is the best.

Roasting generally has three levels: mild, moderate and deep. With the increase of roasting level and the extension of roasting time, the acidity of coffee beans decreases and the bitterness increases; while the sweetness rises first and then decreases, reaching the best when roasting in moderate degree, and the roasting depth will increase the hardness, which also affects the grinding afterwards.

Grinding and brewing

This process is necessary for coffee beans to become coffee, grinding coffee beans into powder, although it seems very simple, but not easy. There are many factors that restrict the grinding degree, such as baking depth, altitude, brewing method, etc., while grinding to control the temperature and thickness evenly, because coffee aroma retention time is very short.

After grinding is the coffee brewing stage, this process is called extraction, in order to obtain the essence of coffee, control the ratio of coffee and water and water temperature, etc., is not easy, this is the real technology live, need a long time of practice accumulation.

At this point, a cup of fragrant coffee was born, although the waiting time for coffee making is very short, but before the time spent is quite long, so good things really are "waiting" out.
