How to freeze maple syrup and what container to choose
Maple syrup is obtained by boiling the sap of the sugar maple tree until its sugar is concentrated, and it can last much longer if frozen in the appropriate container.
The sap of the sugar maple tree is composed of 98% water and 2% sugar, according to Heifer International. Boiling it removes the water and concentrates the sugar, resulting in a thick, intensely sweet liquid that is poured over pancakes and waffles. Its sweetness, with notes of vanilla and caramel, also pairs well with sweet potatoes, ice cream, cooked vegetables, ham, and bacon.
The problem is that syrup loses quality over time if it isn't stored properly. According to Carman Brook Farm, improper storage shortens its shelf life. Freezing is an effective way to store it for a long time, although the type of container affects the process.
Syrup usually comes in plastic or glass containers, according to Ohio State University. If it's in a plastic jug or a resealable bag, it can be frozen directly, according to Maple Roch. If it's in glass or a can, it should be transferred to a glass jar because syrup expands when frozen and glass can break. In that case, it's best to leave room for expansion.
According to Healthy Canning, the syrup doesn't have a fixed shelf life in the refrigerator and, if frozen properly, can last indefinitely. To use it, simply remove it from the freezer and thaw it in the refrigerator or at room temperature; the remainder can be refrozen.
If the syrup is used several times a week, it may be more practical to refrigerate it, as Maple Farmers says it is perfectly safe after opening. If the container is unopened, there is no need to refrigerate or freeze it: Better Homes & Gardens says it can be stored in a cool, dark pantry, as high temperatures and sunlight reduce its shelf life, according to Carman Brook Farm.
