Grinding coffee beans before cooking every time Coffee beans that are ground before cooking can best release the aroma of coffee. So the best time to grind coffee is before making coffee. The ground coffee is easy to oxidize and lose its fragrance. Especially in the absence of proper storage, the coffee powder is also easy to change taste, and naturally it is impossible to cook fragrant coffee. It is recommended that when grinding with a grinder, do not grind too much beans at once, just enough volume for one serving. That is because the longer the grinder is used at one time, the more prone to heat, indirectly leading to the coffee beans to be heated during the grinding process and the aroma to be released in advance, which will affect the aroma of the cooked coffee. Easy to operate Simply place the coffee beans in the bowl of the coffee grinder and turn the handle several times. The ground coffee then falls into the drawer and so you have coffee.
