Selecting, storing & prepping black tea
- Selecting
- Black tea is fully oxidized during processing, giving it a darker color and bolder flavor than green or white teas; loose-leaf versions generally offer more nuanced flavor than tea bags, which often contain smaller, lower-grade leaf fragments.
- Storing
- Dry black tea keeps 1-2 years in a sealed, opaque container away from light, heat, and moisture, though flavor is freshest within the first year.
- Prepping
- Using freshly boiled water (around 200-212°F) and steeping black tea for 3-5 minutes brings out its full flavor without the bitterness that comes from over-steeping.

Key metrics
Nutrient density
Per 100 kcal, black tea delivers about 3% 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.
