Ground coffee beans Note 1. Fresh grinding and drinking

The ideal time to grind coffee is before it is cooked. Grind only the required amount for the top grade. Because ground coffee is easy to oxidize and lose flavor, especially in the absence of proper storage, coffee powder is also easy to change flavor.

Ground coffee beans Note 2. Thickness & cooking time

Ground 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 excessive extraction, coffee may be very bitter and lose aroma; on the other hand, if the powder is very coarse and cooked too fast, resulting in insufficient extraction, then coffee will be tasteless, because there is no time to dissolve the water-soluble substances in the powder.

Ground coffee beans Note 3.

When grinding with a bean grinder, do not grind too much at a time, enough powder for one use is good, because the longer the bean grinder is used, the easier it is to generate heat, 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.

Grind coffee beans Note 5. Grinder

* Coffee beans contain oil Lu, so the bean grinder must be cleaned after grinding, otherwise the oil deposits, and there will be stale smell for a long time, even if it is a high-grade bean, it will be ground into a strange smell powder.

* After each use of the bean grinder, be sure to wipe the blade with a damp cloth and clean the plastic top with warm water. But for flavored coffee popular in the United States, the added flavor is strong and heavy, and it will last for a long time. It is best to put two spoonfuls of white refined sugar into it before washing.

* Preferably a grinder only grinds the same kind of beans, then there is no problem of mixing flavors.

Ground coffee bean thickness

Coffee beans grinding methods can be divided into coarse grinding, medium grinding and fine grinding according to their size. Use appropriate grinding methods depending on coffee appliance. Generally speaking, the shorter the cooking time, the finer the ground powder; the longer the cooking time, the coarser the ground powder.

Espresso machines take a short time to make coffee, so the powder is the finest, and the coffee powder is as fine as flour.

◆ Siphon method to cook coffee, about a minute, coffee powder is medium thickness grinding.

◆ American filtered coffee takes a long time to make, so the grinding of coffee powder is the coarsest, like the grains on the shell beach.

The secret to grinding coffee beans

The grinding tool for coffee beans is a bean grinder. Bean grinders can be divided into three types:

● Manual rotary bean grinder for home use. (Suitable for leisure people with small needs, large particles and kill time.)

● Electric bean grinder for household use. (It can grind coffee powder of various particle sizes, and can grind 6 people at a time.)

● Professional electric bean grinder. (For commercial use, it can grind more than one pound or less of coffee powder at a time.)

The most important thing to note about grinding coffee beans is the following two points:

● Reduce grinding heat. (Grinding heat will cause coffee aroma to dissipate prematurely)

● Uniform particle size. (uneven particle size will lead to brewing time can not be controlled)

Therefore, if you use a home-style manual grinder, rotate it gently so that it does not generate frictional heat as much as possible. To sum up, if you consider the quality of ground beans, the amount of ground beans, and the use of time and convenience, the use of household electric grinding machine will be the best choice.
