Coffee making DIY (6) selection and purchase of coffee beans

Among the factors that affect the taste of a cup of coffee, raw bean quality accounts for 60%, roasting accounts for 30%, and production factors account for 10%, so in addition to coffee production methods, coffee beans are the key, so how to select good coffee beans?

First of all, freshness is very important. No matter how good beans are roasted, the aroma components are slowly volatilized and released with contact with the air. at the same time, the coffee bean itself oxidizes and absorbs moisture in the air, and the taste changes slowly change, and the aroma and flavor of coffee are on sale. After two weeks, the volatile aroma in the coffee beans has been lost. Over time, the changes in the taste caused by oxidation and moisture make the coffee beans sour. The sweetness decreased, the bitterness became more prominent, and the richness and balance of the overall taste decreased. Therefore, the use of beans roasted within two weeks can best understand the aroma and taste of coffee, choose coffee beans as fresh as possible. This requires attention: (1) keep an eye on the baking date. (2) purchase in a small amount, only the amount consumed in a week or so.

Second, in addition to the general name of the coffee producing country, the boutique coffee beans will specifically identify the production region, grade, raw bean production year, and even refine to the farm name, such as the coffee beans that also belong to Guatemala. Humen Coffee currently uses Finca Entre Rios Organic,Sierra de la Minas, Guatemala city,Guatemala, which is organically produced from Entre Rios Farm in the Sierra de la Minas area east of Guatemala City. So pay attention to consult the store for more information about coffee beans.

Third, in addition to the marked information, what is more important is the actual evaluation. Fresh coffee beans will first have a very fresh and rich aroma, chew one, very crisp, and can feel very rich sour, bitter, sweet and other rich taste.
