Fine Coffee Powder introduces three freshly ground Coffee
Coffee beans, the dark brown beans seem ordinary, but they have a lot of knowledge at all stages. For a coffee cook and drinker, it is enough to have a general understanding of the professional knowledge of the cultivation, production and roasting of coffee beans, and the production can be left to the coffee merchants. After all, this is an era of paying attention to the division of labor. However, it is the user's responsibility to grind and make coffee, and we must have a clear understanding.
When grinding beans, the size of the powder depends on the way it is cooked. The shorter the cooking time, the finer the ground powder; the longer the cooking time, the thicker the ground powder. Sixth, in terms of the actual way of cooking, it takes a very short time for the ESPRESSO machine to make coffee, so the grinding is the finest, and the coffee powder is as fine as flour; it takes more than a minute to cook coffee in the "plug wind" way, and the coffee powder belongs to medium-sized grinding; American filter coffee takes a long time to make, so the coffee powder is the thickest, one by one like Beijing grains on a shell beach. Grinding coffee powder with appropriate thickness is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine and cooked for a long time, resulting in over-extraction, the coffee may be very bitter and lose its aroma. On the other hand, if the powder is coarse and cooked too fast, resulting in insufficient extraction, the coffee will be tasteless because it is too late to dissolve the water-soluble substance in the powder.
There are different brands and types of bean grinders for grinding coffee, and the ideal one is a grinder that can adjust the thickness of the beans. When grinding with a bean grinder, do not grind too much at one time, just enough powder for one time, because the longer the bean grinder is used at one time, the easier it is to get hot, which indirectly causes the coffee beans to be heated in the grinding process and causes the aroma to be released in advance, which will affect the aroma of the cooked coffee.
Coffee beans contain oil, so the bean grinder must be cleaned after grinding, otherwise the grease will be fouled and will smell stale after a long time, and even the most advanced beans will be ground into a strange-smelling powder. After each use of the bean grinder, be sure to wipe the blade table with the wet market and clean the plastic top cover with warm hot water. But for the American popular flavored coffee, the added flavor is strong and strong, and it will last for a long time. It is best to put two tablespoons of white Jing sugar in and beat it before cleaning. Of course, it is better for a grinder to grind only the same kind of beans, so there is no problem of mixing.
According to the size of coffee beans, the grinding methods can be divided into rough grinding, medium grinding and fine grinding. Use the appropriate grinding method according to the coffee utensils.
There is also medium fine grinding or very fine grinding (powdered coffee powder) which is finer than fine grinding. The time to grind coffee beans is to grind only the required amount of coffee before brewing coffee. After the coffee bean is ground into powder, its surface area increases and absorbs moisture, which is easy to oxidize. In short, with the passage of time, coffee powder also plays a role of deterioration to damage the flavor.
And after the ground coffee beans are placed, the carbon dioxide retained inside the coffee beans will be lost together with the aroma. In this way, when the coffee powder is extracted and filtered, the coffee powder should be expanded without expansion, and the coffee can not be brewed anyway. The secret is to consider that grinding and homework should be consistent. The coffee brewed in this way is the most delicious and mellow.
