How we tested spoilage

We stored our opened Appenzeller cheese block in the fridge at approximately 40°F (4°C) for a total of 21 days, closely monitoring it for signs of spoilage. During this period, we observed the cheese daily, noting any changes in smell, appearance, and texture. By the end of the storage time, we detected a faint off odor and noticed some slimy patches forming on the surface, along with dried edges. To further verify its safety, we briefly heated a small piece to 165°F (74°C) but ultimately decided to discard the cheese due to the questionable signs we observed. Safety was our priority, so we ensured nothing potentially harmful remained in our fridge.

Frequently Asked Questions

What's the difference between expiration and best quality dates?

The expiration date on the Appenzeller cheese block indicates the date until which the cheese is expected to remain safe to consume.

For optimal taste and texture, it is recommended to consume the cheese within a few days of opening while it is at its peak freshness. While the cheese may still be safe to eat past the expiration date if stored properly, the quality may not be as desirable.
