Expiration & Storage Tips
When does blue cheese expire?
Unopened blue cheese generally remains good for up to three to four weeks beyond the printed sell-by date. Once opened, a blue cheese will typically retain its best quality for one to two weeks in the refrigerator. If you choose to freeze your blue cheese, which is not typically recommended due to potential texture and flavor changes, it can extend its shelf life, typically up to 6 months.
How do you tell if blue cheese is bad?
Blue cheese naturally has a strong, pungent smell, so don’t let that be your guide. Instead, look out for any changes in color beyond the normal blue or green veining. If the cheese is developing black or brown spots, it likely has gone bad. Additionally, if you notice that the cheese has become excessively hard, crumbly, or it has developed a slick or slimy surface, those are signs of spoilage. Always trust your senses: If something tastes or smells off, it’s better to be safe and toss it out.
Tips for storing blue cheese to extend shelf life
• Keep your blue cheese tightly wrapped, ideally in parchment or waxed paper, and then place in a resealable bag.
• Store it in the crisper drawer or the coolest part of your fridge.
• If you notice the cheese drying out, a quick trick is to add a sugar cube in the bag, which helps maintain moisture levels.
• Don't cut into your blue cheese until you're ready to use it to maintain its freshness.
• If freezer storage is necessary, freeze in small amounts you will use within a short time to prevent wide temperature changes.
