In addition to the unique properties of coffee beans, the roasting degree of coffee beans, the fineness of coffee powder grinding, water temperature, brewing speed, techniques, and so on, all determine the flavor of a cup of coffee.

Coffee from some places, such as Manning, is famous for its mellow taste, and the bitterness of the taste is obvious. African beans are sour, but the bitterness is less prominent.

We sometimes drink coffee as bitter as traditional Chinese medicine because:

1. It's baked too deep.

two。 The water temperature is too high

3. When making coffee, the current is too slow and too small.

4. The proportion of powder and water is not right.

5. It takes too long. Wait.

So, it all shows that this cup of coffee has failed to brew, so do you still think the more bitter the coffee, the better?
