Caffeine is an alkaloid that can stimulate physical and mental activity, this stimulant can also relieve a person from headaches. You can get your next portion of caffeine from a variety of drinks - tea, soda and, of course, coffee. Interestingly, the amount of caffeine will vary depending on the type and method of preparation of the aromatic liquid.
Instructions
Step 1
Comparing ground and instant coffee, scientists came to the conclusion that there is two or even three times more caffeine in a dry instant product than in a natural ground drink. But the level of content of a natural alkaloid varies depending on the type of coffee, the method of its preparation, the climatic zone of the cultivation of raw materials and many other nuances.
Step 2
The most "caffeinated", which means the most invigorating today, is the Robusta coffee. The parameter reaches 2.2%, while in Arabica the amount of caffeine is 1.2%. Slightly less caffeine in Ethiopian "Mocha", "Santos", "Peru". By the way, when drinking the drink, the level of caffeine practically does not affect the bitterness of coffee and its taste. Therefore, it is impossible to determine the content of the stimulant by eye.
Step 3
If you take into account the degree of roast of the coffee, there will be less caffeine in heavily roasted coffee beans. It's a paradox, but raw materials with a rich aroma and no less pronounced taste will not be as invigorating than coffee with a slight roast. This is due to the fact that during the heat treatment of the grains, the molecules of the stimulating substance are gradually destroyed.
Step 4
It is also necessary to take into account the grinding of coffee when buying. The thinner it is, the more caffeine will be in the product. And vice versa. This is because caffeine is washed out of small particles faster and more efficiently with water during the preparation of the drink. It also matters how long the coffee will be brewed. The longer it takes to cook, the higher the caffeine level will be. That is why a drink from the press, which is infused for some time, will be stronger. And cooked with steam ristretto - less. With this brewing method, the coffee particles come into contact with moisture in only 20 seconds.
Step 5
There is also little caffeine in espresso, although it is considered to be the strongest in taste, like ristretto. There will be more stimulating substance in Turkish coffee brewed in a drip coffee maker. Therefore, drinking such drinks is not recommended in the evening. And the Italians, who are recognized as connoisseurs of coffee, use the scalding black liquid with milk, so they do not suffer from insomnia.
Step 6
Today, you can determine the level of caffeine in coffee or other drink using a special sensor. It works on the principle of a traffic light, if the device shows green, the caffeine content is low. Yellow is normal and red is high.
