How much tannin is in tea and Diet Coke?

The amount of tannin in tea varies depending on the type of tea and how it is brewed. Generally, black tea has the highest tannin content, followed by green tea, and then white tea. The longer tea leaves are steeped, the more tannins are released into the water.

On average, black tea contains between 100 and 200 milligrams of tannins per cup. Green tea contains between 50 and 150 milligrams of tannins per cup, and white tea contains between 25 and 75 milligrams of tannins per cup.
