Parmigiano-Reggiano is a prestigious, hard Italian cheese known for its granular texture and nutty flavor profile. Because it is aged for a long period before it ever reaches your kitchen, it possesses a much lower moisture content than softer cheeses, making it exceptionally durable. While many people assume that all cheeses spoil quickly once opened, this specific variety is quite resilient. However, maintaining the correct environment—specifically controlling humidity and preventing exposure to air—is essential to preserve its signature crystalline structure and savory taste. Whether you are using a large wedge for grating or a smaller piece for snacking, proper storage ensures every bite remains high-quality and delicious.

Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
