Even the baristas rave about it! By using a ceramic filter, you can enjoy the original flavor of the beans because the oil content of the beans comes out, and the oil content, which is the umami component of the coffee beans, passes through well by the effect of the exquisite eye (hole) which is a little larger than the paper filter. This is the secret of its deliciousness. In addition, by filtering water, tea, tea, and alcohol, it becomes mellow and easier to drink, because it removes the smell of calcium and impurities contained in the water.
