Ozone Coffee Roasters

Ozone Coffee Roasters is a London-based specialty roaster with roots dating to 1998, according to a review by Balance Journal. Before arriving in the UK capital, the company operated elsewhere — the specifics of that earlier chapter aren't well documented in public record — but Ozone has since established itself as one of London's longer-tenured independent roasters, distinguished by a deliberately seasonal catalogue that rotates as harvests arrive rather than holding a fixed menu year-round.

The company's longevity sets it apart from the wave of UK specialty roasters that emerged in the 2010s. Founded before third-wave terminology had taken hold in the British market, Ozone has navigated multiple cycles of consumer taste and industry consolidation to remain independently operating with an active wholesale programme and direct-to-consumer retail. The broader founding story — who started it, the original mission, how the London move came about — is not detailed on the current website.

Ozone's sourcing leans on long-term direct partnerships with producers, a claim backed by what appears on their current offering list: Thai anaerobic naturals from Asor Merlaeku (a collaboration labelled 'Beanspire x Merlaeku'), Bolivian Catuai processed via a coconut-ferment 'Coco Natural' method, and classic Kenyan SL28/SL34 AA washed lots from Kiriga. The range spans medium to medium-dark roasts and includes green unroasted options for home roasters. Single origins, limited special-edition reserves, and house blends run alongside a subscription programme.
