GQ/Rock coffee grinder can enjoy a cup of mellow espresso in 30 seconds.

For coffee lovers, it can't be happier to enjoy a cup of mellow coffee when they get up early in the morning, especially these days when coffee is available, and many people are willing to prepare a cup of coffee for themselves in the morning. However, in the process of brewing coffee, grinding beans takes up a lot of time. Of course, the automatic bean grinder is quite convenient, but the noise caused by it is also easy to be cleared, and manual grinding of beans can take a lot of time. Therefore, a design shows that it only takes 30 seconds to grind a copy of double espresso's "Rock Coffee Grinder," which has become a target on the recruitment website, making many coffee fans look forward to it.

Rock coffee grinder is developed by therefore, a British design company. it is mainly designed for modern people to taste a cup of mellow coffee in the quickest time in their busy lives, so the goal of this grinder is to shorten the time for grinding beans. The screw blade specially designed in the interior of the machine can grind the beans without spending too much effort, and you can also rough the powder you want. for example, people who like to drink French rice should grind a little bit, coffee a little bit, and worry about the problem that the grains should be different.

However, short time is the most important feature of Rock coffee grinders.

At present, the Rock coffee grinder is raising money for the indiegogo collection, which is expected to be launched in May 2015. it will sell for US $149and 4470 yuan per Taiwan.
