If there’s a general answer to this question it will be that everybody has it’s own right way to drink his coffee.

The coffee preparation heavily varies on the country or region that you origin is. For instance I have heard that in Brazil they seems to brew a whole pot of coffee, usually with milk and all the family drinks it. In Venezuela they seemed to brew filter coffee in these cloth filters. (Excuse me if my information is not that exact. This is only to illustrate the different ways of preparing coffee)

When you go to Italy, there won’t be many places that you can have anything but espresso, very short, very concentrated and explosive taste…

Then more factors will follow. Will you add sugar? Will you enjoy some milk or creamer in your cup? This will heavily depend on one’s own preferences, and a little bit on the coffee quality. If your beverage is utterly bitter, you tend to need more sweetness in order to balance the flavor and the milk will also add a touch of sweetness due to its natural ingredients.

Eventually the right way will be only in your head and the only thing that you have to do is drink your coffee with a lot of joy and happiness.

For me, it will typically be either espresso or filter, and if I have more bitterness in my cup, I’ll tune the preparation act a bit, in order to balance my coffee. No sugar, no milk!
