Expiration & Storage Tips
When does shredded cheddar cheese expire?
Unopened shredded cheddar cheese usually has a 'sell by' or 'best by' date printed on the package; this typically gives you a good idea of its shelf life. In general, once it's unopened, it will last 1-2 weeks beyond this date in the fridge. Once you open the bag, it's best to consume the cheese within 1-2 weeks. For a long-term option, shredded cheese freezes quite well! When properly stored in the freezer, it can extend its life for up to 6 months. To defrost frozen cheese, transfer it to the refrigerator overnight. It will maintain its texture better if you thaw it slowly this way. However, its quality and texture might not be exactly the same as it was prior to freezing. It could be a bit crumbly and is best used melted in cooking or baking.
How do you tell if shredded cheddar cheese is bad?
Spoiled shredded cheese can exhibit several telltale signs of spoilage: an off smell, discoloration, and mold. Cheese that has gone bad often smells sour or even costic and unnatural. If you notice any blue, green, or black spots or have a strong, unbearable smell, it's best to discard it. Another sign of spoilage is if the cheese has started to harden or dry out; this is nature's way of telling you it has lost its freshness. With shredded cheese, discoloration could be harder to spot due to the small size of the shreds, but a sniff test and checking for any discolored or moldy shreds should help.
Tips for storing shredded cheddar cheese to extend shelf life
• Store opened cheese in an airtight plastic bag or container, squeezing out as much air as you can. Air speeds up mold growth.
• Freezing shredded cheese can extend its shelf life, just be sure to store it in airtight bags with all the air squeezed out.
• Don't store cheese with strong-smelling foods. As a cheese breathes, it will absorb other odors and begin to taste like those items.
• Store cheese in the coolest part of your refrigerator, usually the bottom drawer. Temperature fluctuations can affect its flavor and consistency.
