Oatmeal is derived from hulled oat grains, known as groats, which can be either milled (ground), steel cut or rolled. When oats are ground, they are referred to as "white oats." Steel cut oats are often called "coarse oatmeal," "Irish oatmeal," or "pinhead oats." Notably, Quaker white oats are produced using both controlled organic and bio-dynamic methods, utilizing natural fertilizers and herbs to foster plant growth.
