99%+ Purity Theanine (Theanine,L-Theanine) CAS No.: 3081-61-6

Product Summary:


Sweet tea is a style of iced tea commonly consumed in the United States,especially the Southern United States. Sweet tea is made by adding sugar to bags of black tea brewing in hot water while the mixture is still hot. The tea is traditionally served ice-cold with only sugar. It may sometimes be flavored, usually with raspberry, lemon, or mint. Sweet tea can also be made with a simple syrup and is sometimes tempered with baking soda to reduce the drink's acidity.

Although sweet tea may be brewed with a lower sugar and calorie content than most fruit juices and sugary sodas, it is not unusual to find sweet tea with a sugar level as high as 22 brix (percent weight sucrose in water), twice that of Coca-Cola.
