Expiration & Storage Tips
When does grenadine expire?
Commercially-prepared grenadine, when unopened, can last up to three years past its printed manufacture date if stored correctly. Once opened, it's best consumed within six months if it's kept in a cool, dry place such as a pantry. In a refrigerator, that timeline can extend up to a year. Homemade grenadine tends to have a shorter lifespan, usually around a month in the refrigerator due to its lack of preservatives. Freezing grenadine is not commonly practiced, but it can be done if the desire is to extend its life further. Freezing could considerably prolong its usability, even up to a year, though it might slightly alter its texture.
How do you tell if grenadine is bad?
It's important to note that grenadine does not entirely spoil, but its quality does diminish over time. You'll know your grenadine isn't at its peak when it starts losing its vibrant red color or begins to develop a dull, hazy appearance. The syrup might also thicken or become clumpy. An off-putting smell is a definitive sign that it's time to toss your grenadine. If you notice any signs of mold, it's a strong indication that your grenadine has gone bad.
Tips for storing grenadine to extend shelf life
• Store unopened grenadine in a cool, dry, and dark place, preferably in a pantry or a kitchen cabinet.
• Once opened, close the bottle tightly after each use to prevent air from getting in and degrade its quality.
• Refrigerating grenadine after opening will help keep its flavors fresh and extend its lifespan significantly. Remember to keep it in the fridge door, not at the back as the temperature fluctuates less at the door.
• If you decide to freeze your grenadine, make sure to leave some headspace in the bottle to allow the liquid to expand without breaking the container.
• As a general rule, always use clean utensils when handling grenadine to avoid introducing any bacteria that could necessitate premature discarding.
