R.W. Knudsen Family is a brand of natural bottled juices. They manufacture over 125 different products, many using organic ingredients. Their most well-known line is a family of natural, non-carbonated juices sold in 32 fl. oz. glass jars, available in the United States at natural food stores and supermarkets. Other products include Recharge, a sports energy drink marketed as a natural competitor to drinks such as Gatorade, and Spritzers, a line of carbonated juice-flavored drinks sold in 12 fl. oz. aluminum cans. All of Knudsen's products are shelf-stable without refrigeration; as such, they do not directly compete with refrigerated juices such as Odwalla and Naked Juice.
