Yogurt keeps 1–2 weeks in the fridge at 4°C or below, according to USDA's FoodKeeper — once opened, aim for the shorter end. Greek yogurt and skyr can outlast regular yogurt because of their higher acidity. Whey separation on top is normal — stir it back in. A sour smell beyond the usual tang, fuzzy mold, or a bitter aftertaste means it's done. Trust your senses more than the date stamp once the container is open.
How to store yogurt
Keep yogurt on a middle or back shelf of the fridge, where temperature stays most stable — never in the door. Aim for 1–4°C. After opening, smooth the surface and seal the lid tight; air contact speeds up spoilage. Use a clean spoon every time to keep bacteria out. Freezing yogurt works for cooking and smoothies (up to 2 months) but the texture turns grainy when thawed, so plan accordingly. Once it starts pooling watery liquid heavily, it's near the end.

Frequently asked questions
How long does yogurt last after opening?
Yogurt keeps 1–2 weeks in the fridge. Once opened, reseal it tightly, keep it under 4°C and aim for the shorter end.
Can you eat yogurt past the expiration date?
Sometimes — the date is mostly about quality. USDA's FoodKeeper suggests using yogurt within 1–2 weeks; check smell, taste, and look for mold.
Can yogurt be frozen?
Yes, up to 2 months. The texture turns grainy after thawing, so it's better for smoothies and baking than for eating plain.
