Expiration & Storage Tips
When does brown sugar expire?
Brown sugar has an indefinite shelf-life when stored properly. This means that unopened brown sugar can last forever if not exposed to humidity. Once opened, it retains its quality for at least 2 years if you keep it in an airtight container or tightly wrapped not allowing the air to get in. If you have some homemade brown sugar, the expiration guidelines remain pretty much the same. It's also possible to freeze brown sugar, in case you're storing larger quantities. When you decide to use it after freezing, let it thaw at room temperature for few hours until it becomes soft again.
How do you tell if brown sugar is bad?
The smell and texture are your main clues for determining if brown sugar has gone bad. Fresh brown sugar has a rich, caramel-like aroma. If it’s hard, lumpy or has an off smell, it may not necessarily mean that it's bad, but it's definitely gotten some moisture and become hardened. Run it through your fingers: if you feel any alien objects, or if the color has turned from its normal brown to a lighter or darker shade, then it’s better to play it safe and discard it. Please note, brown sugar does not really spoil, but it does become hard and lumpy if not properly stored.
Tips for storing brown sugar to extend shelf life
• Store it in an airtight container to keep the moisture out.
• Keep the container in a cool, dry place, such as your pantry.
• Add a slice of bread or a couple of marshmallows to the container to keep the sugar soft.
• Consider storing large quantities of brown sugar in the freezer. To defrost, simply let it reach room temperature before using it.
• Keep it away from strong odors as it can absorb them and this can change the taste and smell of brown sugar.
• If it hardens, briefly microwave it in a bowl covered with a damp paper towel to restore its softness.
