Know the basics of caffeine boutique coffee

When it comes to coffee, the first thing that everyone thinks of is caffeine, but what is caffeine? It is estimated that it is difficult for everyone to give an accurate answer. I have been engaged in coffee work for several years, and I would like to share it with you: caffeine is a mild stimulant, and it contains a small amount of caffeine in our daily drinks such as tea, cocoa and chocolate. Caffeine is also found in carbohydrate drinks such as cola and certain narcotics. It can speed up the metabolism of the human body and keep people clear-headed and alert. Coffee is especially popular for its "pick-me-up" properties. Caffeine can stay in the body for hours, and its effects on the body vary from person to person. Some people lose sleep when they drink coffee at night, others get nervous and hyperactive when they drink too much coffee, but many people are unaffected.

Once we understand how the body responds to caffeine, we can use it to satisfy our own needs. Drinking a cup of delicious coffee before studying for exams or driving long distances will definitely reduce fatigue. Caffeine in coffee is insoluble in cold water, but soluble in hot water. It stimulates the cerebral cortex, eliminates drowsiness, enhances touch and thinking, and adjusts heart function, as well as dilating kidney blood vessels and diuretic effects. However, caffeine is not limited to coffee, usually a 100cc cup of coffee contains 60 to 65mg of caffeine, green tea has 200 to 300mg, black tea has 350 to 400mg, cocoa has about 100mg. Too much caffeine intake, prone to tinnitus, hyperactivity (rapid heart beat, increased pulse rate), and uneven pulse beat, so you must drink coffee in moderation.
