Pure maple syrup should be kept in a cool, dark place for up to two years until opened and then refrigerated after opening where it will last one year. If excess water is present or if containers are not clean when filled, there may be the growth of bacteria, yeast or mold during storage.
Maple Syrup unopened. will keep for a long time. Glass keeps the best; we have a bottle over 50 years. old on our shelf that is still good. Plastic we normally recommend not keeping. for more than 18 months to 2 years and tin should be stored no longer than 6.
