Vacuum sealing versus traditional herb storage — which is better?

May 8, 2026

Quick Answer

Vacuum sealing is better for long-term herb storage due to its ability to prevent moisture and air from entering the container, preserving the herbs' potency and flavor. Traditional storage methods often rely on airtight containers, but may still allow some moisture and air to seep in. This results in a shorter shelf life for the herbs.

Choosing the Right Vacuum Sealer

When it comes to vacuum sealing herbs, a good quality sealer is essential. Look for a model with a strong suction power, typically measured in inches of mercury (inHg). A device with a suction power of at least 27 inHg can effectively remove air from the container.

Preparing Herbs for Vacuum Sealing

Before vacuum sealing, it’s essential to properly prepare the herbs. Remove any excess moisture from the leaves by gently patting them dry with a paper towel. This step is crucial in preventing the growth of mold and bacteria. You can also add a silica gel packet or a small amount of desiccant to the container to absorb any remaining moisture.

Best Practices for Vacuum Sealing Herbs

When vacuum sealing herbs, it’s essential to use the right container. Look for a container specifically designed for vacuum sealing, such as a glass jar or a plastic container with a wide mouth. Avoid using containers with narrow necks or those with sharp corners, as they can cause the vacuum sealer to malfunction. Always check the vacuum seal after sealing to ensure it’s tight and airtight. If necessary, re-seal the container to ensure the best possible preservation of the herbs.
