Caffeine contents of clonal tea; seasonal variations and effects of plucking standards under Kenyan conditions

Caffeine contents of clonal tea; seasonal variations and effects of plucking standards under Kenyan conditions

Food Chemistry 20(3): 225-233

Clones of tea have different contents of caffeine. The tender younger leaves of tea bushes contain higher caffeine contents than older leaves. Leaf stalks accumulate small amounts of caffeine. Fine plucking standards ensure a high caffeine content in brewed tea. Seasonal fluctuations in 2 leaves and a bud differed by 24-30% in caffeine content, depending on clones.
