Yes. Because twisted tea is an alcoholic iced tea beverage made of tea leaves brewed to become a hard iced tea which not only tastes like real iced tea but also delivers an incredibly smooth and refreshing drinking experience.
Caffeine content has largely to do with how the tea is grown, and packaged. Tea that is grown in the shade produces a lot more caffeine than the sun grown plants. Those that has been finely chopped, sliced, or ground into a powder will have a much larger caffeine output than leaves.
This is because more caffeine is able to escape from the leaf when it is cut. Newly grown leaves and buds are often used to make white tea, and these contain more caffeine than when older full-grown leaves.
Caffeine affects people differently, depending on their size, gender and sensitivity to it. In people who are sensitive to caffeine, even moderate amounts can cause insomnia (trouble sleeping), rapid heart rate, anxiety and feelings of restlessness.
Cut down slowly on the amount of caffeine in your diet. If you have developed a dependence on caffeine, an abrupt cutback can cause headache, fatigue, difficulty concentrating and even flu-like nausea and muscle pain. Check out some tips for breaking the caffeine habit at Clevelandclinic.org
