The basics of coffee how to make coffee with excellent flavor at home?

With regard to the knowledge of brewing coffee, according to the head of a coffee shop, it is necessary to fully master it. Interpreting the essence of coffee requires at least a year of complete professional training, but at present there is no such training environment in China. If you want to brew a good cup of instant coffee at home, here is a little secret for you: first put a little warm milk into the pot, then add the right amount of coffee powder and boiled water (the proportion is about 3G coffee powder plus 140c.c. Boiled water), heat to a slight boil (be careful not to boil completely), then turn off the heat, and then add sugar as you like, which can eliminate the peculiar smell of instant coffee and make the coffee more mellow with the milk at the bottom.
