Theine is the same chemical composition as caffeine. Whilst caffeine is used as an overarching term, theine specifies the substance found in tea and spreads over six to eight hours in the blood, three times longer than caffeine. How much theine a tea contains depends on the fermentation period. Gong continues to explain that black tea (full fermentation) contains the highest level of theine per serving, followed by oolong (semi-fermented), green and white tea.
TEAS FOR HEALTH
Some people avoid drinking tea because of the theine content. Although teas with theine have a stimulating effect, there are health benefits too. Gong states,
“Tea contains other ingredients, such as antioxidants, which help reduce the risk of heart diseases and give better skin.” Maranda Barnes, Co-founder of TWG Tea, concurs. “Black tea may improve digestion and drain the body of excess fluids. It is also very effective against bodily fatigue. Researchers have shown that tea consumption can speed up the metabolism when regularly consumed; pu’er, in particular, helps in the digestion of rich foods.”
If you are sensitive to caffeine, fear not, for there is an alternative: white teas. Barnes adds, “White teas are naturally low in theine content, a rare tea that is unprocessed and simply picked and sun- dried.” TWG Tea created blends as White Night Jasmine Tea and White Spring Tea, in addition to single estate harvests as Yin Zhen tea and Pai Mu Tan tea from Fujian in China, for those who prefer to consume less theine.
