How Long Will Cheese Last?

The length of time a cheese can last depends on the variety. In general, the harder the cheese, the longer it will last. Once you have cut into it, or if it’s cut by the cheesemonger, it’s best to eat cheese within two weeks of purchasing it. A whole wheel (uncut) will last much longer. Over time the flavor of cheese may change. If it smells ammoniated or tastes bitter, it's probably time to throw it out. Don't worry, though, a cheese that has "gone off" can't hurt you. It just doesn't taste very good. In general, it’s always best to buy only as much cheese as you can eat within two weeks.
