To fully enjoy the flavor of coffee, freshly ground coffee is the best choice. As the name suggests, freshly ground coffee is coffee that is ground and brewed immediately. If you want to make freshly ground coffee yourself, a coffee bean grinder is an indispensable tool. However, there are a wide variety of coffee grinders to choose from! Just search for "coffee grinders" on an online shopping platform, and you'll see all kinds of designs, prices ranging from tens to tens of thousands of yuan, and various grinding effects. It's overwhelming. This often leads customers to ask for advice in stores, so I've compiled some purchasing suggestions for your reference.

1.Power of the Coffee Bean Grinder Currently,

 Coffee grinders on the market are mainly divided into two categories: manual coffee grinders and electric coffee grinders. The core difference between them lies in the source of power. Manual coffee grinders rely entirely on human power to drive the grinding blades. By manually turning the handle installed on top of the grinder, the grinding blades inside will start to rotate and grind the coffee beans.

Because there is no built-in motor, manual coffee grinders are usually very compact and easy to carry. If you are a beginner who wants to gradually explore coffee, or a student or traveler who always needs coffee, a manual coffee grinder that doesn't require electricity and is reasonably priced would be a great choice.

 Electric coffee grinders, on the other hand, rely on a motor to drive the grinding blades. Therefore, they need to be plugged in to operate. The advantage is that they can grind coffee beans quickly and easily, without requiring much human effort or time.

However, due to the built-in motor, most electric grinders are relatively large in size. Additionally, they need to be plugged in to function, so their usage scenarios are relatively fixed and cannot be easily moved. If you have a sufficient budget, a fixed coffee brewing environment, and don't want to spend too much time and effort grinding coffee, an electric grinder would be a good choice.

2. Grinding Blades of the Coffee Bean Grinder

The grinding blades of coffee grinders are mainly divided into three types: flat burr, conical burr, and serrated burr. Due to different grinding methods, the shape and particle size distribution of the ground coffee will vary.

Flat burr are a common type of grinding blade. Their grinding method is mainly "shaving". After the coffee beans are added, they are shaved into flakes or chunks by the sharp texture of the flat blades (with more fine powder). Coffee powder with this shape has a larger surface area in contact with water, so the extraction speed of substances is relatively faster, resulting in a more intense coffee flavor (but it is also more likely to extract negative flavors), and the flavor is more complex.

Similarly, conical burrs are also quite common. Their grinding method is mainly "rolling", so the coffee grounds they produce are mostly irregular chunks with relatively less fine powder. Due to the larger volume and thicker nature of these particles, it takes longer for water to penetrate into the coffee grounds. This slows down the dissolution rate of substances, making the brewed coffee less prone to over-extraction.

On the other hand, the serrated burr burrs, strictly speaking, are an improved version of flat burrs. Their structure is the same as flat burrs, consisting of two burr discs, but their cutting edges are modified into gear-like shapes. This modification effectively reduces the squeezing during grinding, resulting in more uniform particles and less fine powder. The grinding method of ghost tooth burrs is mainly "grinding", so the coffee grounds they produce are more like spherical polygonal particles. Additionally, the distribution of coarse and fine powder is relatively even, so the brewed coffee has higher consistency and body.

So, the above are the two ideas for choosing a coffee grinder shared by our store. You can find a suitable grinder based on your own needs and purchase it from us.
