I have drunk both black coffee and instant three-in-one G7 coffee, among which black coffee is always available. The most important thing is of course that it is healthy and helpful to lose weight. This black coffee has a strong fragrance, and it tastes bitter but not sour, which is completely different from the black coffee I drank before. Moreover, this kind of tea can be brewed both in hot and cold, with no sucrose added and a strong cocoa flavor.
