Rocky Mountain Mustard Company is owned and operated by Four Corners Products, LLC. Along with its sister company, Colorado Hot Sauce, RMMC specializes in spicy condiments and gourmet sauces. Located in Fort Collins, CO., we get most of our ingredients from local vendors. The majority of owners are either alumni or faculty at Colorado State University (or both), and we’re excited to be a part of the Colorado Proud culinary scene!
