How do you pick out the best coffee beans from the forest? This may be the biggest puzzle you have standing in front of the container. Every serving of coffee beans looks very attractive to the naked eye. Sagebrush coffee takes you to see who is the real good beans!

Choose fresh coffee beans. Pay attention to whether the color and particle size of the beans are consistent when purchasing. Good coffee beans have a shiny appearance, and have a strong aroma and no odor. No matter what kind of coffee beans, freshness is an important factor affecting quality. When purchasing, grab one or two coffee beans in the mouth to chew, crisp sound (indicating that the coffee is not wet), teeth cheek fragrance is the top grade, but it is best to pinch with your hand, feel whether solid, rather than buy crispy coffee. If the coffee beans have lost their aroma or smell old, it means that the coffee beans are no longer fresh and are not suitable for purchase.

Freshly fried coffee beans are not suitable for immediate drinking and should be stored for a week in order to completely release the gases in the beans. Generally speaking, the best drinking period of coffee is one week after frying, when the coffee beans are the freshest and the aroma and taste are the best.

In addition, the purity of coffee beans is also another consideration factor, experts choose coffee, not to see the size of the particles, but to grab a handful of single coffee beans, about dozens of weight, to see whether the color of each single bean is consistent, particle size, shape is similar, so as not to buy mixed beans disguised as inferior products. However, if it is a comprehensive bean, different sizes and colors are normal phenomena. In addition, heavy fire and medium and deep roasting method will cause coffee beans to be oily, but if the beans are lightly roasted, it means that they have deteriorated, not only the degree of fragrance is reduced, but also astringent and sour.

The ideal amount of coffee beans to buy is half a month to drink it is appropriate.

Ripe beans taste more stable

Andrea Illy believes that roasted coffee needs to be matured in a monitored environment before packaging, because matured coffee beans have a more stable taste. Freshly fried coffee beans sometimes have a green taste, which will disappear after one night. New beans, on the other hand, have a taste of baked bread, which those who insist on growing beans may not have tasted. In some coffee shops, freshly roasted beans are put on shelves overnight. While taste changes over time, guests can also see it as an extra journey, witnessing coffee's ups and downs.

coffee beans

After harvest to market before shipping to remove the skin, pulp, skin and silver. There are two methods: drying (also known as natural method or non-washing) and washing.

dry type

The method is simpler. First of all, the fruit will be just picked widely spread in the sun for a week or two, until the fruit issued a cracking sound so far, natural drying. After that, the husker removes the dried pulp, endocarp and silver skin.

Coffee beans refined in this way are slightly sour and bitter. Almost all coffee beans grown in Brazil, Ethiopia, Yemen and other places are obtained in this way. The disadvantages of this method are that it is easily affected by weather and easy to incorporate defective beans and other impurities. Therefore, it must be carefully screened.

water washing type

The fruits to be harvested are put into a flowing water tank, and after the fruits floating on the water surface are removed, the skin and pulp are removed by a pulp removing machine. Then put it in the sink and remove the floating pulp. After that, move into the fermentation tank, soak for half a day to a day, and then dissolve the colloid on the surface of the fermented coffee beans.

After washing with water, drying for several days, drying with a machine, and finally removing the endocarp with a huller, it becomes a raw coffee bean that can be used as a commodity. In this way, coffee beans will be more beautiful than dry coffee beans, and less impurities. Colombia, Mexico, Guatemala and other countries about 70% of the production are using this method.

mode comparison

Coffee beans have already begun processing after harvest, otherwise they will begin to ferment, causing coffee beans to produce odors. The treatment methods are mainly "drying" and "washing", which will cause different flavors. Dry beans have a complete natural alcohol flavor, gentle aroma and more gum; washed beans have a good alcohol flavor, high aroma and lively acidity, which is also the source of sweetness in espresso coffee.
