Skyr yogurt may develop an off smell, changes in texture such as separation or curdling, and visible mold growth. If any of these signs are present, it should be discarded.

Skyr yogurt can be used as a base for smoothies, salad dressings, or as a substitute for sour cream in recipes.
Greek yogurt or regular yogurt can be used as substitutes for skyr yogurt in most recipes, though the texture and flavor may vary.
The dates are manufacturer guidance and not absolute safety indicators to eat for a limited time if stored properly, but quality may decline.
To determine if Skyr yogurt has gone bad, check for any visible signs of mold or an unusual discoloration on the surface, which indicates spoilage. If it emits a sour or off smell that differs from its typical tangy aroma, it's best to discard it. Additionally, if the texture appears excessively watery, lumpy, or grainy instead of creamy, it's a sign that the yogurt has spoiled.
Improper storage or consumption of expired skyr yogurt can lead to foodborne illnesses. Always check for signs of spoilage and adhere to storage guidelines to minimize risks.
To extend shelf life, store skyr yogurt at the back of the fridge where the temperature is most consistent. Consider using a thermometer to ensure the fridge maintains the ideal temperature.
