No, vanilla syrup doesn't technically expire in the same way that perishable foods do. However, its quality and shelf life depend on several factors.
Shelf Life of Vanilla Syrup

Unopened: Unopened bottles of vanilla syrup typically last between 12 and 36 months, depending on the brand, storage conditions, and the type of bottle. [Source: Adams and Russell] The high sugar content acts as a preservative. [Source: Reddit r/starbucks, Quora]

Opened: Once opened, the shelf life significantly reduces. Proper storage is crucial. Expect an opened bottle to last 3-6 months if stored correctly (capped and in a cool, dark place).

Factors Affecting Shelf Life
-
Storage: Keeping the syrup in a cool, dark place, away from direct sunlight and heat, extends its shelf life. [Source: Reddit r/nespresso]
-
Packaging: The type of bottle and its seal also affect how long the syrup remains fresh.
-
Usage: Frequent use increases the likelihood of contamination, reducing its shelf life.
Signs of Spoilage
While vanilla syrup doesn't "expire" in the traditional sense, you should discard it if:
- It develops an off-putting odor or smell.
- It changes color significantly.
- Mold or other visible signs of spoilage appear.
In summary, while vanilla syrup has a long shelf life, it's essential to pay attention to its appearance and smell after opening. Proper storage significantly extends its usability.
