Although people who like hand-grinding have different reasons, it is certain that not everyone likes this way. Here we assume that there is a hand-grinder and an electric grinder of the same grade, and compare the advantages of hand-grinding and electric grinding.
The hand-operated coffee grinder does not generate heat during grinding
In theory, hand-operated coffee grinders are less likely to generate heat during grinding, so the flavor of the ground coffee is less likely to be affected. Most electric coffee grinders grind at high speed, and high-speed friction will cause the temperature of the coffee powder to rise slightly in a short period of time, which may change the taste of the coffee.
But in fact, the difference caused by this part is so small that it is difficult to detect, even experienced coffee industry workers may not be able to detect the difference, and you may not be able to detect the differences when brewing coffee.
Although it is theoretically possible that a hand-operated coffee grinder can produce better coffee, it is unlikely that anyone would choose to use it for this reason. Electric coffee grinders are widely used by roasters, cup testers, and baristas, proving that as long as you use freshly roasted coffee, you can grind coffee with good flavor.
Hand-operated coffee grinder is smaller and cheaper
For those with limited space or budget, a hand-operated coffee grinder is a better choice than an electric grinder, as it is smaller and cheaper.
Just like electric coffee grinders, hand-crank coffee grinders come in various shapes and sizes, and are distributed across a variety of price ranges. However, high-end hand-crank grinders are much cheaper than their electric counterparts of the same class, and are also less space-consuming. A good hand-crank coffee grinder can cost around 1000+ yuan, while a similarly good electric coffee grinder can easily cost more than 3000+ yuan.
The hand-operated coffee grinder operates quietly
The hand-operated coffee grinder is quieter than the electric coffee grinder because it does not grind at high speed. No matter what kind of electric coffee grinder you use, the huge noise of operation may wake up your sleeping roommate, especially when there is a sleeping baby or child at home. You definitely don't want to wake them up with the noise of the coffee grinder.
The hand-operated coffee grinder does not require electricity
Obviously, hand grinders do not need electricity, which may not make much of a difference if you make coffee at home or in the kitchen, but it is a big advantage for those who like to camp and travel and do not have plug-in power available. If you travel frequently, there are several travel-friendly hand grinders that can easily enjoy freshly ground coffee on the road or in the wild, enhancing some of the taste of life.
The hand-operated coffee grinder is more nostalgic
Finally, the hand-shaking bean grinder has a nostalgic look. The old design is as popular as the new design, and the old design can be a medium of conversation among retro enthusiasts. If you are interested in the nostalgic look of the hand grinder, you have two choices, either the newer model, which is out of date, or the old model, which is over a century old. The Volkswagen Group Co. Older models of hand players in good condition usually still have very good grinding capacity, although they may be more expensive than older, newer models.
But a hand grinder may not be suitable for you
In some cases, the advantages of an electric bean grinder will be more than that of a hand-operated bean grinder. For example, if you want to grind a large amount of coffee, you don't want to only grind it by hand; or when you don't have much time to grind the beans slowly; or you want to make espresso, because the espresso must be brewed as soon as possible after grinding to allow the aroma of the coffee powder to be brought into play, which cannot be overcome by the slow grinding characteristics of the hand-operated bean grinder.
But if you just want to drink freshly ground coffee anytime and anywhere, then a hand-crank coffee grinder is a good choice.
