White Tea
White tea is harvested from the first harvest of the season and has the least amount of processing. Due to these factors white tea technically should have the highest levels of caffeine.
Processing Steps
Harvest - Bud only, one leaf and bud, two leaves and a bud
Drying - The final step to lock in the flavor, character, and stability of the tea. Drying also reduced the moisture level of the leaf which stops oxidation
Each tea producer will process their tea to their own specification, so additional steps may be applied. The steps above are the basic processing steps.
