The basics of grinding coffee beans

Coffee is one of the most popular drinks in the world, and grinding coffee beans is a key step in making a delicious cup of coffee. Grinding coffee beans correctly can extract the best taste and aroma. Here are some tips on how to choose and use the right coffee beans and how to grind them correctly.

Choosing the right coffee beans

First of all, you need to choose coffee beans that are fresh and of good quality. Freshness is essential to maintaining flavor, so it is recommended to buy single origin coffee that is not pre-packaged or already packaged but marked with information such as the production date and shelf life, either whole or packaged shortly after being ground.

Secondly, when purchasing, you should choose varieties of different types, origins and processing methods (such as washing, natural drying, etc.) according to your personal taste preferences. Each variety has its own specific flavor characteristics, such as the Brazilian production area is mostly chocolate-like sweet; the Ethiopian production area is mostly floral and berry flavor; the Colombian production area is mostly balanced and smooth, etc.

Preservation of coffee beans

Storing coffee beans properly can preserve their freshness and flavor. Coffee beans should be stored in a dry, cool place away from direct sunlight, preferably in a sealed container to isolate air and moisture. Avoid exposing coffee beans to the air for too long, as they will absorb odors from the surrounding environment.

In addition, it is recommended not to grind a large amount of coffee beans in advance. Once the outer protective shell is damaged, the coffee beans will lose their flavor faster. It is best to grind the appropriate amount of coffee beans on the spot before each brewing.

Choose the right grinding tool

Choosing the right grinder is crucial to achieving the desired taste. The two most common types are manual and electric.

Manual grinders have less friction, are easy to operate, and are relatively inexpensive, making them suitable for personal use. They usually use ceramic blades or sharp metal blades to grind coffee beans.

Electric grinders have greater friction and faster speed, making them suitable for commercial use. They are usually equipped with blades of different coarseness or conical grinding discs to adjust the size of the powder as needed.

Choose the right grind

Different brewing methods require different degrees of coffee bean powder. Here are some common brewing methods and the corresponding recommended powder size:

• Fine grind: espresso machine, Turkish pot
• Medium crush: drip coffee machine, French press
• Coarse crush: hand pour pot, condensation filter (chemex)

Grinding coffee beans correctly

Finally, pay attention to the correct grinding process of the coffee beans.

1. Weighing:

In summary, choosing the right fresh and high-quality coffee beans, storing them correctly, choosing the right pounding equipment with less friction, simple operation, relatively low price or high friction and fast speed, and weighing, preheating and adjusting correctly to start a uniform and continuous grinding process are the keys to making a delicious cup of coffee. I hope these basic common sense can help you enjoy a better coffee experience at home.
