Here's everything you need to know about the super sweet orange, including where to find it: What Is Sumo Citrus? The Sumo Citrus, also called the Sumo Orange, is a hybrid of navel oranges, pomelos and mandarins. It was first cultivated in the 1970s in Japan, where it's known as Dekopon. In the U.S., they are grown in California's San Joaquin Valley. The large, seedless, easy-to-peel fruit looks kind of like a misshapen orange with bumpy skin and a protruding bump on top (called a "topknot"). "Sumo Citrus" is a brand name, but it's become a generic term to refer to the fruit in the U.S. What Does Sumo Citrus Taste Like? Sumo Citrus is super sweet with a distinctly citrus-like flavor. It tastes like other oranges, but less acidic and tart. All Sumo Citrus fruits should have the same level of sweetness, regardless of size. The variety was bred not only for its sweetness, but also for it's easy-to-eat anatomy: Its skin peels away without a mess and the segments separate easily. Plus, there are no seeds to contend with. Sumo Citrus Season Like other citrus fruits (including lemons, limes, and grapefruits), Sumo Citrus are in season during the winter. You can find them in stores every year from January to April.

There may be slight variations from fruit-to-fruit in size, peel texture, and topknot prominence — none of these things will affect the quality.
