Earlier this year I wrote about the power of buying in bulk. That post was focused on my bulk hop purchase, but also discussed the important factors for storing malt in bulk. Storing malt generally requires a low-humidity environment around room temperature in an air tight container. The caveat with storing anything in bulk is the need to use it in a timely fashion. So storing base malt in bulk is really the only legitimate option for homebrewers since we have to buy 50+ pounds at a time.
I was finally pushed over the edge for buying malt in bulk while planning a 10-gallon batch of IPA. At my local shop, the cost for 22-pounds of grain is close to the cost of a sack of the pale malt I generally use. So for about $5 more than I would have been spending I took home an additional 33-pounds of grain. Sounds like a pretty good deal to me.
So now how do I take proper care of my new found riches of grain? I decided to use buckets and Gamma Seal Lids. These screw-on lids are made of food safe plastic and snap on to buckets. They say the lid can work on 3.5-gallon to 7-gallon buckets. ;In keeping with the food safe theme, I used 6-gallon fermentation buckets. Two 6-gallon buckets held 55-pounds of grain with ease.
The Gamma lid does mention a rubber mallet might be needed to get the lid to snap onto the bucket. I found that by removing the screw-on top the ring snapped easily on the rim of the bucket without the mallet. It was more difficult to attach with the screw-on top in place.
Overall, I’m very happy so far with this solution.The buckets are easy to store and the lids make them air-tight and very accessible. The best part of it all is the savings from buying one sack of grain paid for the buckets and lids. From now on I will continue to save money on base grain!
