how long does homemade simple syrup last
Homemade simple syrup typically lasts 2 weeks to 1 month in the fridge when stored properly in an airtight container, though richer versions (2:1 sugar-to-water) can stretch to 6 months.
Shelf Life Basics
Standard 1:1 simple syrup (equal parts sugar and water) stays fresh for about 2-4 weeks refrigerated, as its balanced ratio allows some microbial growth over time. Richer syrups last longer due to higher sugar content acting as a preservative—up to a month or 6 months—while flavored or fruit-infused ones spoil faster, often in 1-2 weeks, from added moisture or organics. Forum users on Reddit echo this, suggesting small batches for home use since it's quick to remake, avoiding waste.
Storage Tips
- Always refrigerate in a clean, airtight glass jar to block air and contaminants.
- Label with the date and type; avoid room temperature storage, which cuts life to 1 week max.
- For longer life, freeze in ice cube trays —thaw as needed; many bartenders swear by this for syrups.
Signs It's Gone Bad
Toss if you spot cloudiness, crystallization, mold, off odors, or sliminess —better safe than sorry in drinks or desserts. One mixologist notes smell is key: fresh syrup smells sweet and clean.
