Caffeine content in tea is altered by which factor? A. Infusion time B. Water temperature C. Leaf size D. All of the above

Solutions

Expert Solution

Answer is D.

The amount of caffeine in coffee or tea depends on a number of factors, including the method and length of brewing or steeping. The longer the tea leaves have fermented in processing, the greater their caffeine content. With tea. leaf location on the tea plant affects content of caffeine in that tea.
Caffeine content is also altered by the length of the infusion in water.
