Fresh mozzarella in water lasts 1–2 weeks unopened, 3–5 days once opened — the water it floats in keeps it moist but also a perfect bacterial medium. Low-moisture (shredded or block) mozzarella for pizza lasts 2–4 weeks opened. Vacuum-packed bags hold months sealed. Brine cloudiness, sour smell, or slime mean it's done. Freezing works for shredded mozzarella destined for cooking; fresh mozzarella loses its delicate texture.
How to store mozzarella
Keep fresh mozzarella in its brine in the original container — if you transfer to a different container, use lightly salted water or whey to prevent osmotic damage. Refrigerate at 4°C. Low-moisture mozzarella goes in a sealed bag in the cheese drawer. Once opened, use within a few days; bring to room temperature before serving for best flavor. Freeze shredded portions; don't freeze fresh balls.
