While the handling and filling of each is generally similar, there are some guidelines regarding the use of each which can be offered. A variety of glass, metal, and plastic containers are available for packaging maple syrup. Each type of container has advantages and disadvantages which producers should understand Metal containers represent maple syrup packaged in the most traditional manner. They are well suited for packing in the 1quart to 1 gallon size. When metal containers are clean and dry they are very satisfactory.
Some producers prefer to rinse all cans with hot water before filling.
If this is done they should be thoroughly and rapidly dried before use. If cans are not rinsed, check for loose metal fragments or rust before filling. Once filled, securely install the cap insert and screw on the cap. Glass containers are preferred by some because they permit the natural color of the syrup to be seen. Glass is most common for 1-quart and smaller sizes.
