Greek yogurt keeps 1–2 weeks in the fridge below 4°C, according to USDA's FoodKeeper — once opened, aim for the shorter end. Whey separation (clear yellow liquid on top) is normal — stir it back in. Sharp ammonia smell, fuzzy mold, bitter taste, or pink/yellow discoloration mean it's done. Always use a clean spoon to avoid introducing bacteria.
How to store Greek yogurt
Store greek yogurt on a middle or back shelf, tightly sealed. Avoid the fridge door. After each use, smooth the surface and reseal — air contact accelerates spoilage. Use a clean spoon every time. Freezing changes the smooth texture to grainy; better for smoothies than eating plain after thawing. Whey separation is natural — just stir it back in.
