How Should I Store Lavender Syrup?

Preserving the delicate floral notes of lavender syrup is all about proper storage. Syrup made with real sugar and water will start to degrade in flavor, aroma, and safety once exposed to air, heat, or improper containers.

Best Practices for Storing Lavender Syrup

Always use a clean, airtight glass bottle or jar to minimize contamination and evaporation.
Keep lavender syrup in the refrigerator—not at room temperature—to slow the growth of mold and bacteria.
Label your container with the preparation date so you can monitor freshness.
Do not store near strong-smelling foods, since syrup easily absorbs odors.

How Long Does Lavender Syrup Last?

Homemade lavender syrup generally stays fresh for 2–4 weeks when refrigerated in a sealed container. Over time, you may notice changes in color, aroma, or the appearance of sediment—these are signs it's time to discard and make a fresh batch.

2–4 weeks shelf life in refrigerator is typical for lavender syrup with a 1:1 sugar-to-water ratio.
Check for any cloudiness, sour smell, or visible mold before each use.
Higher sugar concentrations (2:1 ratio) extend shelf life up to 1–2 months.

Extra Tips for Storing Lavender Syrup

Sterilize bottles or jars before filling to avoid introducing bacteria.
Keep syrup away from sunlight—even in the fridge—to prevent color fading.
Consider dividing large batches into smaller containers to reduce air exposure with each use.
Never return unused syrup from the bar or serving area back into the storage bottle.
