How can I properly store simple syrup to ensure its freshness and longevity?

To properly store simple syrup and maintain its freshness and longevity, you should keep it in a clean, airtight container in the refrigerator. Make sure the container is sealed tightly to prevent any contamination. It is also important to use a clean spoon or dispenser each time you take out syrup to avoid introducing bacteria. Stored this way, simple syrup can last for up to a month.
