A 1000lb sack of Honey Malt sprung a leak at work the other day and it was (almost) a complete loss. I managed to salvage ~35lbs of it before it all landed on the warehouse floor. It's now in 3 separate plastic bags in my brew room, but I want to store it in plastic rubbermaid/tupperware type sealable containers. How long can I store it and it still be "good"?
