Expiration & Storage Tips
When does dark chocolate expire?
Store-bought dark chocolate has a long lifespan, given its minimal dairy content. If unopened, it can last two years or more from its production date if stored properly. After opening, the shelf life reduces slightly, but you can still expect it to be good for up to 1 year. If you have chosen to freeze dark chocolate, it can extend its shelf life to 18 months without loss of taste or texture. For handmade dark chocolate, it's best to consume within a couple of weeks as it is likely made fresh without preservatives.
How do you tell if dark chocolate is bad?
Detecting if dark chocolate has gone bad is quite straightforward. Firstly, check for a dull, discolored appearance. Good-quality dark chocolate should have a glossy, smooth surface. If it starts to look gray or blotchy, it's probably past its prime. Secondly, chocolate can develop a condition called 'bloom' - white or grayish spots and streaks that occur when fat or sugar rises to the surface. It's a sign the chocolate is old, but it is still safe to eat. However, the texture and flavor may be off. Lastly, if the chocolate smells stale or off, it's probably spoiled and should be discarded.
Tips for storing dark chocolate to extend shelf life
• Keep your dark chocolate in a cool, dry place with a temperature between 60-70°F (15-21°C). It doesn't necessarily need to be stored in the fridge but remember to keep it away from heat sources.
• To avoid moisture, store your dark chocolate in an airtight container. Exposure to air and moisture can promote oxidization and result in off flavors.
• If freezing the dark chocolate is necessary, wrap it tightly in plastic wrap and then put it in a zip-top bag. Ensure it's properly sealed to avoid absorbing odors from the freezer.
• Before using frozen chocolate, it is important to thaw it at room temperature to avoid condensation forming on the surface which can result in a soggy texture.
• Lastly, keep dark chocolate away from strong-smelling food items like spices or garlic. Chocolate can absorb the odors of anything around it, which might affect its pure taste.
