Last Updated: 2026/01/14, It is said that the world consumes 2.25 billion cups of coffee a day, which shows that there are many people who love coffee, but not many people know how to make the perfect cup of coffee, because it involves science. Rick Tingley, a coffee expert at Earl Taylor Black Tea in the UK, suggests that people in the northern hemisphere should choose Colombian coffee beans when they drink coffee in winter, because this is the season when coffee beans are grown there.

It is said that the world consumes 2.25 billion cups of coffee a day, which shows that there are many people who love coffee, but not many people know how to make the perfect cup of coffee, because it involves science. Rick Tingley, a coffee expert at Earl Taylor Black Tea in the UK, suggests that people in the northern hemisphere better choose Colombian coffee beans when they drink coffee in winter, as this is the season when coffee beans are ripe and harvested; then they are best baked in the French Alps because the delicate aroma of coffee beans can be better preserved in low-temperature environments at high latitudes; they should be preserved later.

Before making coffee, grind the coffee beans according to the kind of coffee you want to drink. If you drink Italian-style coffee, grind it finer, almost like flour. Many people use a piston coffee pot to make coffee, first of all, clean the coffee pot thoroughly; a cup of medium concentration coffee needs to use 60 grams of coffee powder with 1 liter of water. If the taste is heavy, put more coffee powder, and vice versa. Do not think of soaking time to change the coffee concentration; the water temperature should be between 88 and 94 degrees Celsius, the coffee will taste less bitter. The coffee powder is soaked for up to 4 minutes, and the longer the time, the more bitter it tastes; then slowly and smoothly press the piston with a filter to the bottom of the pot; finally, pour the coffee into the white coffee cup.

A recent study from the University of Oxford shows that the color of coffee cups can affect the aroma of coffee you feel, and white works best. Adding milk or sugar to the coffee will affect the aroma of the coffee. If you must add it, you'd better choose low-fat milk.
