About Grindstone Blends

Grindstone Blends is a Canadian food and manufacturing company located on Brydges St in London, Ontario. The business serves consumers looking for familiar foods reinvented with modern nutrition, real ingredients, and inclusive manufacturing practices. They offer a variety of products including Cream of Rice in flavors such as Blueberry Cobbler, Maple Butter Tart, and Apple Pie; CUP-CAKE, a convenient cake-in-a-cup treat available in varieties like French Vanilla Confetti and Chocolate Fudge Cake; and The MIX, a versatile baking blend for making pancakes, waffles, muffins, and cookies in flavors like Chocolate, Apple Cinnamon, Golden Maple, and Vanilla Blueberry. The company operates a dedicated manufacturing facility in London where they mill and granulate their own rice to maintain control over texture and quality. Their production environment is specifically designed to be gluten-free, and the facility excludes soy, nuts, dairy, and wheat from production. Grindstone Blends also provides private-label and commercial manufacturing opportunities, including milling, blending, seasoning, and packaging services. The company was founded by Karen Marques, who began the venture after seeking better ways to fuel her active lifestyle and discovering black rice. A key part of the brand's identity is its focus on inclusion; Marques developed the CUP-CAKE product specifically to help families with food allergies participate in celebrations. Grindstone Blends products are available through more than 200 retail locations across Canada, including grocery, natural food, health and wellness, and specialty stores, as well as online.
