Selecting, storing & prepping coffee
- Selecting
- Choose whole beans over pre-ground coffee if possible — ground coffee loses aroma and flavor within days as it's exposed to more surface area and air.
- Storing
- Whole beans keep their flavor for about 2-4 weeks at room temperature in an airtight, opaque container, away from heat and light. Freezing extends this but isn't necessary for coffee used within a few weeks.
- Prepping
- Grinding beans just before brewing, rather than in advance, preserves noticeably more aroma, since ground coffee's larger surface area lets flavor compounds escape quickly.

Key metrics
Nutrient density
Per 100 kcal, coffee 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.
