The Color-Caffeine Connection: Busting the Myth
✔ Truth #1: Oxidation affects color NOT caffeine
Black tea's dark hue comes from theaflavins (oxidized compounds)
Green tea preserves chlorophyll (lighter color) but can have similar caffeine
✔ Truth #2: Real caffeine determinants:
Leaf age - Younger buds contain 50% more caffeine
Shade growing - Matcha/gyokuro develop extra caffeine
Brew time - 5-minute steeps extract 90% of caffeine
