Lower grade leaves contain less nutrient value, not solely because they are crushed, but also because they are poorer quality to start.

Teabags are generally made with low-grade leaves (the twigs, leaves, stems that are located lower on the tea bush) as opposed to the “top” leaves & bud that are used for high quality loose teas.

To counteract loss of flavour, more crushed leaves are used, which results in more caffeine.

When a tea leaf is crushed, the surface area of the leaf is exposed to more air, which causes the tea to lose nutrient value, become stale & lose flavour rapidly.

Since the term “antioxidant” is similar to “oxidation”, it’s important to clarify the meaning of both. This could occur because white tea oxidizes slightly during withering whereas, the oxidation process is stopped early in the manufacture of green tea by the steaming or pan firing of the leaves.
