Canning Maple Syrup #922826

Asked December 11, 2025, 11:14 PM EST

Hello, I recently opened a huge jug of maple syrup. I am hoping to find a way to store this outside of my fridge/freezer and in my pantry instead. Is it possible (safe) to can the syrup in smaller batches using a pressure canner? If so, are there guidelines to how long it needs to be processed? Thank you!

Hello, 

Yes, you can repack and process maple syrup in smaller jars to store in your pantry. Any open jugs or jars should be refrigerated to prevent mold growth, but heat-processed, sealed jars can be kept at room temperature. 

To process and pack the syrup, you could follow instructions for berry syrups. Heat your syrup up to simmering, pour the syrup into clean, hot jars (half pint or pint) and process for 10 minutes in a boiling water canner at elevations less than 1,000 feet.

OSU Extension also has a guide to syrup processing for small scale syrup producers. This guide recommends hot packing syrup in sanitized bottles without using a boiling water canner. Because of the syrup's high sugar content and the high heat used during packing, this method is safe; however, there is a slightly higher risk of mold contamination compared to the canning method. You can read more about that method here.

Thanks for using Ask Extension,

Jared
