Skolnik manufactures Steel Drums for maple syrup packaging and storage. To sterilize the container and prevent spoilage, drums should always be filled with hot syrup. When the drum is properly sealed, a vacuum will be created during the cooling process, preventing contamination from air exposure. Stainless Steel Drums do not interfere with the syrup taste, nor do they change its composition when packaged properly. Drums can range from a volume of 5-110 gallons, and can have 20-16 gauge metal thickness.
