Frequently Asked Questions

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

The expiration date on Asiago cheese indicates the date by which the cheese should be consumed to ensure maximum safety and quality. Beyond this date, there is an increased risk of bacterial contamination and deterioration in quality.

Consuming Asiago cheese before the expiration date ensures both safety and optimal taste experience.

How can I tell if Asiago Cheese Opened has gone bad?

To determine if opened Asiago cheese has spoiled, look for any mold growth on the surface, a strong unpleasant odor, or a slimy or gritty texture. If you notice any of these signs, it is best to discard the cheese to prevent any potential foodborne illnesses.

What are the food safety risks?

Asiago cheese is a type of hard, aged cheese made from cow's milk. Like all dairy products, Asiago cheese is prone to bacterial contamination if not stored properly.
