After the last post on grains, I received some great questions about how I store my grains and flours. Since I buy large amounts of wheat and a few other grains, there's no way that I would be able to refrigerate them. At least not without a walk in cooler. What I do is buy big Cambro buckets at the restaurant supply store (they're open to the public), which will usually hold 25 pounds. They are super handy, and the same buckets/storage containers that restaurants use. I started using them back when we opened our first bakery. They work really well, and are airtight with snug lids. They stack too! I also add a couple of bay leaves to each bucket, to keep bugs at bay.
Of course large glass jars are fantastic too. Depending on the size of the jar/crock, you can often fit a 5 pound bag of grains or flour in them. This is my fave for smaller amounts of grain and flour, and what I keep out on my counter. Large canning jars work well too (like the pic above).
I should add that I do refrigerate brown rice, because this does have the tendency to go rancid pretty quickly. But other than rice, the rest is stored safely in buckets. That reminds me, a cold garage this time of year is a great place to store your grains (which are sealed in buckets or jars, of course). Oh, and in the heat of the summer, I make sure to move the grains to a cool spot inside the house (pantry or closet), because the garage can become very hot that time of year.
