To be clear: Wild Rose does not sell grain.
Canada Malting does however!
1. Contact Canada Malting at 1-866-310-8694 or email Allison at <allison.nimik@canadamalting.com>.
2. She will send you the details on ordering grain. (basically they need a credit card and they will send you the current price list)
3. Their warehouse is by Didsbury and it's cheapest to pick it up there. Otherwise you can make shipping arrangements with them.
If that sounds too complicated, you can always swing by the Vineyard and pick up crushed or uncrushed grain right there. I don't know what their policy is on selling whole bags, but it may be worth asking.
Cheers,
Corey
