The division of labor of coffee beans has knowledge at every stage.

From planting, production, baking, cooking. Perhaps it is enough for everyone to have a general understanding, pay attention to the division of labor and specialization, and leave the specialty of planting and production to the coffee merchants, but roasting, grinding and brewing coffee is the responsibility of you and my users, and we must have a definite understanding.

How to bake a bag of fresh coffee beans is my responsibility, and the packaging is handed over to the consumer, and then he depends on you to show the maximum value of his delicacy.

[baked package]

Roasted coffee beans are easily oxidized by oxygen in the air, which makes the oil deterioration and aroma volatilization disappear, and then accelerate the deterioration by temperature, humidity, sunlight, etc., in order to maintain the aroma and quality of coffee, how to package and preserve coffee beans has become a great knowledge.

[grinding]

Coffee is not ground until it is brewed. Because ground coffee is easy to oxidize and lose its flavor, especially without proper storage, coffee powder is also easy to change flavor, so it is naturally impossible to cook mellow coffee. Some people are afraid of trouble or do not want to buy more bean grinders, so they usually buy ready-made coffee powder when they drink coffee at home. At this time, they should pay special attention to the problem of storage. Because of Taiwan's humid climate, coffee powder should be brewed as soon as possible after opening. The proper way is to put sealed jars in the refrigerator and do not put them in the same place as garlic, fish and shrimp. Because the coffee powder is easy to absorb, it becomes strange-tasting coffee accidentally, and even the best quality coffee is spoiled.

* Grinding beans, the size of the powder depends on the way it is cooked

The shorter the cooking time, the finer the grinding powder will be.

The longer it takes to cook, the thicker the ground powder will be.

* in an actual cooking manner:

It takes a very short time for ESPRESSO machine to make coffee, with the finest grinding, which is as fine as flour.

It takes more than a minute to cook coffee by blocking the wind, and the coffee powder is ground of medium thickness.

American filter coffee takes a long time to make, and coffee powder is the thickest to grind.

Grinding coffee powder with appropriate thickness is very important for 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 excessive extraction is caused by cooking for a long time, 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 first choice is the grinder that can adjust the thickness of the beans. The bean grinder is grinded in stages, and the amount of powder used at one time is about 20g. Because the bean grinder makes it too long at a time, it is easy to heat up, which indirectly causes the coffee beans to be heated in the grinding process and causes the aroma to be released ahead of time, which will sound the aroma of the cooked coffee.

Coffee beans contain oil, so the bean grinder should be cleaned after use, otherwise the oil will accumulate scale, there will be stale smell for a long time, even high-grade beans will be strange smell powder. After using the bean grinder, wipe the blade table with wet cloth and baking soda powder and clean the plastic top cover with warm hot water. But for popular flavored coffee, the added flavor is strong and strong, and it will last for a long time, so it's best to put two spoonfuls of baking soda into it before washing. Of course, it is best for a grinder to grind only the same kind of beans, so there is no problem of mixing flavor.

The grinding methods of coffee beans are roughly divided into three types: rough grinding, medium grinding and fine grinding. Use the appropriate grinding method according to the coffee utensils, but you can also adjust your taste to grind according to your brewing.
