Selecting, storing & prepping green tea
- Selecting
- Green tea leaves are steamed or pan-fired rather than oxidized, preserving more of their natural green color and delicate flavor compared to black tea; matcha is a stone-ground powder made from specially grown green tea leaves.
- Storing
- Dry green tea keeps 6-12 months in a sealed, opaque container away from light, heat, and moisture, since its more delicate compounds degrade faster than black tea's.
- Prepping
- Green tea is best steeped with water cooler than boiling (around 160-180°F) for 2-3 minutes, since water that's too hot can make it taste bitter or grassy.

Key metrics
Nutrient density
Per 100 kcal, green tea delivers about 2% of a Daily Value on average across 22 beneficial nutrients. The score is its percentile for that measure among the 177 foods in our database — higher means more nutrition per calorie. How this is calculated.
Density counts protein, fiber, and vitamins and minerals (not fat, sodium, or sugar), each capped so a single nutrient can’t dominate, with a calorie floor so very-low-calorie foods aren’t overstated. It measures nutrition per calorie within our database — a useful guide, not a complete verdict on how “healthy” a food is.
