What affects tea caffeine?

  • Leaf age: Younger leaves and buds contain more caffeine.
  • Shading: Shade-grown teas (matcha, gyokuro) have boosted caffeine and L-theanine.
  • Water temperature: Hotter water extracts more caffeine.
  • Steep time: Longer steeps extract more caffeine - though most caffeine is released in the first 60 seconds.
  • Tea-to-water ratio: More leaf, more caffeine.
