Experts say coffee dates are quality indicators, not strict safety limits. Unlike milk or medicine, coffee’s “best by” is often set by roasters or sellers. Drinking expired coffee is unlikely to cause health problems, but flavor and aroma decline—oxidation reduces acidity and can produce dull, woody or musty notes. Ground coffee loses freshness fastest after opening; even sealed, its peak flavor may last only days to weeks. Check aroma: if the rich coffee scent is gone or it smells stale, toss it. Discard immediately if you see mold, clumps, or moisture. To keep coffee fresher longer, buy whole beans and grind per brew (home grinders are increasingly affordable). Ultimately, the date tells you about taste more than safety—storage, smell, and personal preference matter most.
