Numerous breakfast cereal brands are owned by the company Attune Foods: the organic Erewhon brand and non-organic, conventional brands Uncle Sam, New Morning and Skinner’s Raisin Bran. Attune was acquired by Post Foods in 2013, which is in turn a property of Ralcorp Holdings.
They write "Since 1966, Erewhon has led the organic revolution and we remain passionately committed to providing the purest organic foods. We use only the whole grains of U.S. grown organic brown rice and organic corn. We never use batters and slurries – each puff of Crispy Brown Rice is an actual grain of rice. Our cereals have no dairy, soy, peanuts or tree nuts in them. Erewhon’s rice and wheat cereals are verified as non-GMO by the non-GMO project, and we proudly offer seven certified gluten free cereals."
