Before the legendary, enormously delicious fruit lands in produce aisles near you, let’s recap everything you need to know about Sumo Citrus. Read on to learn all about the hype, the history, and the hints to ensure you have the one and only authentic Sumo Citrus. Accept no imposters!
The Obsession
People can’t stop talking about Sumo Citrus – and not just our Super Fans. The press, celebrities, influencers, even our growers… it’s hard to find someone who hasn’t fallen in love at first bite.
But why?

The History
Sumo Citrus is a rare variety of fruit that was originally cultivated in Japan in the 1970s by an expert grower who set out to develop the ultimate citrus experience, which was called the “dekopon” in Japan. The fruit immediately became a cult favorite, prized by all who had the chance to savor each juicy, seedless, and super sweet bite.
Fast-forward to 1998, and the first seedlings arrived in the U.S. But, since Sumo Citrus is one of the most challenging varieties of citrus to grow, the public had to wait over a decade for it to arrive in stores!
Since 2011, Sumo Citrus has been growing in popularity. Our dedicated and passionate growers work year-round to ensure each and every Sumo Citrus is perfect, from the time it leaves their farms in California until it arrives in your favorite local grocery store.

The Hints
How can you tell you’ve found the one and only real deal Sumo Citrus in stores? Start with this list of attributes – we think of them as “the three T’s”:

Timing:
Sumo Citrus arrives in stores in January and the season ends in April.

Top Knot®:
While some citrus are perfectly round, Sumo Citrus is not. At the stem end, you’ll see a bump, called the Top Knot. All Sumo Citrus will have one!

Texture:
Feel the skin. If it’s smooth like a lime, it’s not a Sumo Citrus. You want to look for skin that’s bumpy and textured to make sure you’ve found the right fruit.
Finally, and perhaps most importantly, don’t forget to look for the classic sticker – that’s the #1 way to know you have Sumo Citrus!

Every Sumo Citrus has a official purple sticker bearing an image of the fruit and the name. If the fruit you’ve found checks all these boxes, get ready for an enormously delicious experience!
