A record that kept growing
One gardener has broken the longest chili record three times. His latest reached 52.5 centimeters
The Swiss grower spent almost a decade selecting seeds for length. The hardest part was not the heat. It was keeping the pepper straight enough to measure.
Jürg Wiesli's newest chili measured 52.5 centimeters, or 1 foot 8.6 inches, when it was verified in Dozwil, Switzerland, on August 11. The number gave him the world record for the third time. His first winning pepper was 45 centimeters long. The second reached 50.5. Then he spent nearly eight years trying to add two more.
The record moved three times, and every time it was his
Wiesli first took the title in 2017 with a 45-centimeter chili at a local vegetable competition. A year later, he returned with one measuring 50.5 centimeters. That mark held until his 2026 specimen added another two centimeters.
Guinness World Records identifies the pepper as Capsicum annuum from the Joe's Long cayenne variety. Wiesli grew it from seed taken from a 48.5-centimeter pepper he produced in 2025.
The newest result is a length record, not a heat record. A pepper can be unusually long without being the world's hottest, and the official entry makes no claim that this one set both marks.
Ten years of seed selection produced his own strain
Wiesli told Guinness that he has kept seeds from the strongest performers and carried them into the next season. Over time, he gave the line its own name: Wiesli Big Long.
His routine begins indoors under grow lights in March. The plants move outside after the danger of frost passes. He works mature compost into the soil, waters regularly and avoids so much fertilizer that the plant spends its energy making leaves instead of peppers.
That is the record holder's account of his method, not a controlled comparison of growing techniques. The official measurement proves the length of this pepper. It does not prove which single choice made it possible.
Length is useless if the pepper twists
Wiesli says the difficult part is producing a pepper long enough to compete and straight enough to measure cleanly. Long peppers tend to curl. Trying to force one straight after it grows can snap it.
That makes the 52.5-centimeter result feel less like a lucky afternoon in the garden and more like a decade-long exercise in patience. Each season has to produce a pepper worth measuring and seed worth saving.
The record pepper still ended up as food
Wiesli told Guinness that he dries chilies in a wood-fired oven and grinds them into powder. His favorite use is ratatouille with chili, browned ground meat and grated cheese.
He also thinks the record can move again. The next attempt will begin the same way the last three did: with one seed, a long season and the hope that the pepper grows straight.
