Expiration & Storage Tips
When does bittersweet chocolate expire?
Bittersweet chocolate is quite durable and can last a good while. When stored properly, unopened bittersweet chocolate can last up to 2 years beyond the printed date on the package. Once you've opened it, it's best to use it within 6 months to a year for the best flavor and texture. If you've frozen your chocolate (though it's not commonly stored this way), it lasts indefinitely in the freezer, but it's best to consume it within a year of freezing for optimum taste.
How do you tell if bittersweet chocolate is bad?
Identifying spoiled bittersweet chocolate can be pretty straightforward, even for someone new to the kitchen. First, check for discolouration. If your chocolate has developed a dull grey or white coat (known as chocolate bloom), it's not necessarily bad, but the taste and texture might not be at their best. Also, give it a sniff. If it smells off or unusual, it's safer to discard it. Lastly, if you spot any mold, toss it out at once!
Tips for storing bittersweet chocolate to extend shelf life
• Always store bittersweet chocolate in a cool, dry, and dark place, away from strong odors, as it can absorb smells.
• If you want to extend its shelf life, store it in an airtight container. You can use resealable plastic bags or airtight tin containers.
• Freezing chocolate is possible but unnecessary unless you are trying to keep it at its peak for over a year. If you do freeze it, be sure to wrap it in cling film or place it in a zip-top bag before putting it in the freezer.
• To defrost, let it sit in the fridge for 24 hours, then allow it to come to room temperature before using it to prevent condensation from forming on the surface.
