Perfect cup of coffee is pure science

Just pour some water over a teaspoon of coffee machine, you won't get away with that. The perfect coffee listens very closely, according to scientists.

Do you add milk, sugar, cream or sweets to your coffee? Then there is a lot in it that you don't spoil yourself with the ultimate comfort.

According to experts and researchers from Oxford University, among others, five steps are needed for the perfect coffee.

1. The right roasting of coffee

Coffee beans must be heated considerably to bring out their aroma and taste.

When you heat a chicken, the skin becomes brown and crispy. The same applies to coffee beans, and that is due to the chemical Maillard reaction, which occurs under the influence of heat. Amino acids are released and sugars are reduced, so that hundreds of flavorings are released.

Coffee expert Rick Tingley tells the Daily Mail that brief roasting makes the coffee more fruity, while a longer process gives a more roasted taste.

2. Grinding yourself is best

Laziness is not an ingredient in the recipe for the perfect cup of coffee. Tingley strongly recommends grinding your coffee beans yourself.

The grinding of the beans is important because the particles make the size that matches the way you make the coffee. For coffee from the cafetière, for example, the beans must be ground slightly coarser than common salt, to prevent the coffee from becoming too bitter or too flat in taste.

3. Not just any water from the tap

Whatever water you use for your coffee should not be left to chance. The water for the coffee must contain as few minerals as possible. That is why spring water with a low mineral content is ideal.

4. The coffee must now pull

Coffee must infuse in water with a temperature in between 88 and 94 ºC. Switch off the kettle or whistling kettle before the water has reached the boiling point.

Use 60 grams of coffee on a liter of water for the perfect cup.

5. Milk in a white cup

If you use milk in your coffee, you get the best taste through it homogenized milk with a low fat percentage to pour on. Whole milk and cream detract from the aroma of the coffee.

A new study from Oxford University shows that the cup from which you drink the coffee has a lot of influence.

A simple, white cup gives a better balanced, more intense and less sweet taste.

What is a red giant?

In the vast majority of stars, energy is formed when hydrogen melts and turns into helium in the core. Gravity compresses the star's gases, and the pressure and temperature inside the star rise so high that the fusion process can begin. A star like the sun burns on for billions of years.

Huge red flashes of lightning come out of thunder clouds

About red sprites Summer is the season of thunderstorms, so also of 'red sprites': red elves. These gigantic energy discharges can be seen as long red flashes at a height of 70 to 80 kilometers. They are created by very powerful, positively charged lightning bolts with a strength of 300,000 amperes: 10 times as violent as normal, negatively charged lightning.
