Coffee lovers all over the world have different drinking habits and preferences.

People in the Middle East cling to the traditional way of drinking, roasting coffee beans deep to near dark (DarkRoast), usually ground into a very fine powder, and then boil several times and then add sugar to form a small cup of coffee that is extremely thick, bitter, sweet and precipitated. People sipped the small cup of coffee in an elegant and courteous manner.

People in southern Europe and urban Latin America are used to drinking a cup of coffee in the morning, afternoon and evening. They prefer deep-roasted, half-bitter, half-sweet coffee with a scorched taste. It is best to use the coffee brewed by the Espresso machine, a small cup of dark, full-bodied, top floating foam, with a little bit of precipitation at the bottom of the cup. In the morning, a small cup of such coffee is mixed with hot milk in a bowl or large cup. Coffee drinkers hold the bowl or cup in both hands, warm their palms with the heat of coffee or feel the aroma of coffee with their nostrils, and if possible, they even want to jump into the cup and take a bath to keep their spirits free; in the afternoon or evening, southern Europeans prefer black, full-bodied, bitter and sweet coffee.

For people in northern Europe and continental Europe, the preference of a perfect cup of coffee is very different from that of people in the Middle East. First of all, the coffee brewed has no sediment; it is light and round; the beans are roasted brown instead of black. The way of brewing likes to use drip (i.e. DripCoffee) or machine (i.e. Espresso Italian coffee) or all kinds of fancy coffee changed by Espresso ─ cappuccino, Viennese coffee, French milk coffee. Wait.

In English-speaking countries, people are used to adding milk and sugar to their coffee, but because the coffee they drink is relatively light, the added milk and sugar often affect and mask the concentration and original taste of the coffee. The habit of drinking coffee began to be popular in North America during World War II. In order to reduce the cost of drinking coffee and meet the demand at any time, American coffee is usually brewed and placed on an insulated plate to keep warm at any time, and the brewed coffee is very light. Typical North American coffee drinkers use coffee as a daily drink, drinking coffee from office coffee pots all day, or serving coffee at any time while doing housework, not only after meals, but also at the beginning and middle of the day.
