The brewing method of coffee powder the cooking method of coffee beans after grinding

When making coffee, some people like to grind their own coffee beans, while carefully grinding and savoring the aroma of their own coffee. The taste of their own coffee is absolutely very different from that of instant bags. Do you want to try to grind the coffee beans yourself? Today, the editor will tell you what to pay attention to when grinding coffee beans, and what is the key to grinding a good cup of coffee?

Attention to grinding coffee beans 1. Grinding and drinking now

The ideal time to grind coffee is to grind it before it is cooked. Only the amount of coffee you need is top grade. Because ground coffee is easy to oxidize and lose its flavor, especially without proper storage, coffee powder is also easy to change flavor.

Attention to grinding coffee beans 2. Thickness & cooking time

Grinding coffee powder with the right 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, 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.

Pay attention to grinding coffee beans. Component

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.

Pay attention to grinding coffee beans. Grinding machine

* Coffee beans contain oil, so the bean grinder must be cleaned after grinding, otherwise the grease will become fouling and will smell stale over 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 a wet cloth 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, so it is best to put two spoonfuls of refined sugar in it before washing.

* it is better for a grinder to grind only the same kind of beans, so there is no problem of mixing.

Grind coffee bean thickness

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. Generally speaking, the shorter the cooking time, the finer the ground powder; the longer the cooking time, the thicker the ground powder.

The ◆ Espresso machine takes a very short time to make coffee, so the coffee powder is the finest, and the coffee powder is as fine as flour.

It takes more than a minute to cook coffee with ◆ plug (Siphon). The coffee powder is ground of medium thickness.

◆ American filter coffee takes a long time to make, so the coffee powder is the thickest, like grains on a shell beach.

The secret of grinding coffee beans

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

● family uses manual rotary bean grinder. It is suitable for leisure people with small demand, large particles and kill time. )

● household electric bean grinder. (it can grind coffee powder of various particle sizes, and it can grind out 6 parts of coffee at a time. )

● specializes in using electric bean grinder. (for commercial use, coffee powder of more than one pound or less can be ground at a time. )

The following two points should be paid most attention to when grinding coffee beans:

● reduces the heat of rubbing. (grinding heat will cause the aroma of coffee to dissipate early)

The size of ● particles is uniform. (uneven particle size will make it impossible to control the brewing time.)

So if you use a family-style manual bean grinder, you should rotate gently so that it does not produce friction heat as much as possible. To sum up, if we consider the quality, quantity, time and convenience of grinding beans, the use of electric bean grinders for family use will be the best choice.

Usually the coffee will oxidize in half an hour after it is ground, so the taste must change unless the manufacturer adds special gas to prevent oxidation, but it is very difficult for the average consumer to do so, so if you just answer how you keep it, you can buy vacuum jars or sealed cans and really don't put them in a cool, dry place, because it's easy to get wet.

Personal experience sharing the best way to drink coffee is to freshly grind and brew, just like fresh juice. I didn't know it tasted so bad until I drank it myself. It was so mellow and healthier.
