I purchased the 32-ounce Dry Grains Container to make bread dough.  I haven't tried it yet for this purpose, but have used it to grind coffee beans and flax seeds.  I love all my Vitamix products! My bread dough recipe may be a bit large for the 32-ounce container.  Maybe Vitamix would consider making a Dry Grains Container in the 64-oz size.
