The French introduced coffee to Vietnam in 1857. In early 1900, coffee was grown in some northern provinces such as Tuyen Quang, Lang Son and Ninh Binh. Tea is also grown in the Central region, such as Nghe An and Ha Tinh provinces.
Caffeine, also known as trimethylxanthine, coffeine, theine, mateine, guaranine, methyltheobromine or 1,3,7-trimethylxanthine, is an xanthine alkaloid that can be found in coffee beans, tea, cola seeds, guarana berries and (small amounts) in cocoa beans.
Every day, Beethoven makes himself a cup of coffee from 60 coffee beans, while Voltaire drinks up to 50 cups a day and lives until the age of 83. Therefore, perhaps coffee addiction is not necessarily a bad thing!
