Jeremy Clarkson is expanding his business empire with new trademark applications, including for his Diddly Dunkers biscuits. The Clarkson's Farm star currently sells the product at his Diddly Squat Farm Shop in Oxfordshire, run by his wife Lisa Hogan. According to reports, he is set to trademark the name, alongside applications for drinks from his Hawkstone brewery, such as Arrowhead, Firelight, Midsummer and Knollbury Fort.
Clarkson bought the 1,000-acre farm in 2008 and began documenting his farming efforts in 2019, leading to the hit Prime Video series. Despite the show's success, he recently stated he would only continue if there was a compelling story. His business ventures also include The Farmer's Dog pub, which he took over in July 2024, though he claimed in June 2025 that it would be his last entrepreneurial move, describing business as “relentless” and saying he is “not motivated by money.”
The fifth season of Clarkson's Farm is set to premiere on 3 June and will focus on a devastating outbreak of bovine tuberculosis (bTB) that struck the Cotswolds farm in October 2025. The disease, caused by Mycobacterium bovis, forces the culling of infected cattle and has been catastrophic for farmers. Clarkson called 2025 the “worst year ever” for his farm, citing a “shocking” harvest due to heatwaves and drought.
