Decaf: La Plata, Colombia

Climpson & Sons is an East London institution, roasting single-origin filters and espresso blends from origins like Ethiopia, Rwanda, Peru and even Myanmar. They're a certified B Corp built on long-term relationships and quality over volume, with seasonal coffees rotating alongside the regulars and a flexible subscription if you want it sorted. Rooted in the city's coffee culture — their Broadway Market days are the stuff of London legend — they run cafés, sell wholesale and put real effort into brew guides and education. Mostly UK-focused. A dependable, well-loved pick if you want clean, seasonal single origin specialty coffee from London.
