Selection and purchase of boutique coffee utensils household small bean grinder

In addition to considering the appearance and style and workmanship, the purchase of a household small bean grinder should also focus on the quality of the inner core steel of the first bean mill, the speed of the second grinding bean, the uniformity of the third thickness, and whether the thickness of the ground coffee powder can be adjusted.

It is recommended not to buy a propeller bean grinder (that is, a bean grinder with two blades driven by an electric motor). It is actually not a bean grinder, but a "bean chopper". Its disadvantage is that the coffee powder cut out is of different thickness; second, the process of chopping beans produces high heat, which destroys the precious oil and aroma of coffee beans; third, it can not adjust the thickness of coffee powder. Attachment: brewing method VS particle thickness match 1, rough grinding: the size is as big as coarse sugar, suitable for filter coffee. Second, medium grinding: gravel, the size between crude sugar and granulated sugar, suitable for drip cooking. Third, fine grinding: size as fine granulated sugar, suitable for distilled coffee pot, electric coffee pot, mocha pot. Fourth, very fine grinding: the size is between salt and flour, suitable for Espresso, because household grinders can not grind this texture, generally must buy ready-made grinding powder, so if you want to enjoy Espresso at home, it is best to drink a large amount of fresh coffee.
