Yes! All Blendtec blender models can to this. You can add 1-2 cups of wheat berries or other grains into your FourSide jar (or 2-3 cups in your WildSide+ jar). By grinding, your jar will permanently become cloudy. This is just cosmetic and will not harm or hamper your food; however, please note cosmetic alternations are not covered under your jar warranty. We suggest buying a separate jar for grains.
