How Storage Conditions Affect Blue Cheese Freshness
The environment where you store blue cheese plays a major role in how long it stays fresh. Temperature, humidity, and exposure to air all contribute to mold growth and rancidity.
Keep blue cheese wrapped in parchment or wax paper and then place it in a loose covering in the main part of the refrigerator. Avoid storing it too close to strong smelling foods, as blue cheese can absorb odors easily.
Signs That Blue Cheese Has Spoiled
Even though blue cheese is mold ripened, unwanted spoilage mold and off flavors can develop over time. Knowing what to look for helps you avoid eating cheese that is no longer safe.
Visual and Smell Indicators
Fresh blue cheese should have creamy colored streaks of mold and a mild, tangy aroma. Discard the cheese if you see pink, yellow, or fuzzy mold, or if it smells sharply sour like ammonia.
Texture and Flavor Changes
A noticeable change in texture, such as excessive dryness or a slimy surface, indicates that the cheese has deteriorated. Off flavors, excessive saltiness, or a bitter aftertaste are additional warning signs that the product is no longer enjoyable or safe.
Proper Handling and Packaging Techniques
Correct handling extends the shelf life of blue cheese and preserves its characteristic flavor. Small adjustments in how you store and serve the cheese can make a significant difference.
Use a clean knife each time you cut into the cheese to prevent cross contamination. If you buy a large block, portion what you need and wrap it tightly to limit repeated exposure to air and moisture.

FAQ
Reader questions
Can blue cheese go bad in the refrigerator if I never open it? Yes, even unopened blue cheese can go bad over time. Check the expiration date on the packaging, and inspect the cheese for any off smells or discoloration before using it. How can I tell if crumbled blue cheese has spoiled?
Crumbled blue cheese that looks dull, feels slimy, or has an ammonia like smell should be discarded. Fresh crumbles should hold their shape slightly and smell pleasantly tangy.
Is it safe to eat blue cheese that has developed surface mold?
If the mold appears to be unusual colors or fuzzy, it is best to throw the cheese away. Surface mold on blue cheese can sometimes be trimmed, but if the odor or texture is off, err on the side of caution.
Can freezing change the texture and flavor of blue cheese?
Freezing can alter the texture of blue cheese, making it more crumbly once thawed. While it remains safe, the flavor may become milder, so freezing is best suited for cooked dishes rather than serving on a cheese board.
