We recommend tea for those who do not like coffee. 

Caffeine contributes to the bitterness of tea. Caffeine in tea leaves is higher in young buds and lower in mature buds, so matcha and gyokuro, which are made by picking young buds, have higher caffeine content.

It prevents drowsiness and improves intellectual work capacity and athletic performance. In addition, moderate exercise with caffeine helps to improve endurance, as fat is used as an energy source before the nutritional source (glucose = glycogen) in the muscles. Tea is also said to be effective against hangovers, because caffeine enhances the metabolism of alcohol.

Caffeine occurs naturally in the tea plant, Camellia sinensis, so all brewed tea contains some caffeine. If you dislike the taste of coffee but you need to activate your brain, you can try to drink Ocha.
