Feta lasts 1–2 weeks once opened, refrigerated below 4°C — keeping it submerged in its brine helps it stay at its best for that whole time. The salty brine is what preserves it; dry feta dries out and tastes harsh. Sealed feta keeps until the date on the pack. Sour, fizzy, or ammonia smell means it's done. Mold on feta is more serious than on hard cheese — when in doubt, throw it out.
How to store feta
Store feta submerged in its brine in the original container, or transfer to a glass jar with lightly salted water (1 tsp salt per cup) if there's no brine. Refrigerate at 4°C. Replace the brine weekly if homemade. Crumbled feta from a tub lasts shorter than block-in-brine. Don't freeze — texture turns crumbly and watery.
