How Long Does Nectar Last? Storage, Expiration & Freshness Guide
Nectar comes in many forms—from the agave sweetener in your tea to the fruity mango drink and even the sugar water for hummingbirds. Because these products vary so much, their storage needs do too.
Shelf Life of Nectar
Data suggests the following for fresh nectar:
- Pantry: Lasts 12–18 months (360–540 days) when unopened.
- Refrigerator: Once opened, fruit nectars must be refrigerated. While specific data varies, generally consume within a week.
Note: Agave nectar is much more stable than fruit nectar.
How to Tell if Nectar is Bad
Don’t risk ruining your drink or harming local wildlife. Look for these signs:
- Fermented Smell: A yeast-like or alcoholic odor indicates fermentation.
- Mold: Any visible fuzz on the surface or rim.
- Texture: If it becomes slimy or develops strange clumps (distinct from natural sugar crystallization).
- Color: Darkening can indicate age/oxidation.
Storage Tips
- Agave: Keep in the pantry. If it crystallizes, warm it gently.
- Fruit Nectar: Refrigerate immediately after opening.
- Hummingbird Nectar: Change every 3-5 days, or sooner in hot weather, to prevent fermentation.
Frequently Asked Questions
Does agave nectar go bad?
Agave nectar is shelf-stable and can last a long time, but it can eventually degrade in quality. Crystalization is natural and doesn't mean it's spoiled.
How to store agave nectar to extend shelf life?
Store agave nectar in a cool, dark pantry. Ensure the lid is tightly sealed to prevent moisture and contaminants from entering.
Does hummingbird nectar expire or spoil?
Yes, homemade hummingbird nectar (sugar water) spoils quickly, especially in heat. It can ferment in just a few days, which is harmful to birds.
How long does mango nectar last after opening?
Once opened, fruit nectar like mango should be refrigerated and typically lasts about 5-7 days. Always check for off smells or mold.
