Coffee can not be tasted by everyone's body. People with palpitations and insomnia have to drink less coffee because of caffeine. Caffeine in coffee can lead to insomnia and emotional excitement. And so on, which makes people who love coffee but can't drink coffee choke their wrists.

Today, the so-called decaffeinated coffee on the market means that the coffee beans are processed before roasting to separate 94% to 98% caffeine, resulting in a significant reduction in caffeine content.

It is said that Goethe, a famous German poet, is also a coffee lover, but he suffers from the pain of being unable to sleep after drinking coffee. The feeling of love but not closeness makes Goethe go to his friend Runge to analyze the composition of coffee beans and find out why coffee interferes with sleep. Around 1820, Longi found out that the factor affecting sleep was caffeine and developed a way to separate coffee beans from caffeine, so Lungi became the ancestor of decaffeinated coffee.

At that time, although Lungi found the factors that affect coffee sleep, the technology of extracting caffeine could not produce decaffeinated coffee in large quantities until 1903, when Ludwig Roselius, a German importer of coffee beans, found that as soon as the coffee beans were soaked in sea water, the caffeine content decreased a lot, so he hired a group of chemists to research and develop the technology of extracting caffeine, which made an important breakthrough in the extraction technology. Decaffeinated coffee is just beginning to be mass produced.

Although Lungi was the first to study the effect of caffeine on sleep, the driving force of low caffeine was Goethe, the great poet.
