"Prepare for the unknown by studying how others in the past have coped with the unforeseeable and the unpredictable."-- George S. Patton
We just toss the 10 and 25 lb bags in a large air tight barrel along with bags of salt. I do keep a few large Dessicant packs in the barrel with the desiccant packs in a open plastic bag sitting on top.. The plastic bag is just for safety to put a layer of protection between the sugar and the desiccant.Sugar and salt have stayed 90% soft for years.
