Janson Geisha Alpes /908 Natural Nx

Coffea Circulor is a Swedish roaster obsessed with two things: transparency and seriously high-end coffee. Going since 2005, they specialise in top-tier single-origin lots and wild experimental processing, publishing detail on pricing and supply chain that most roasters keep quiet. They even run their own estate in Kenya alongside partnerships with named producers in Panama, Colombia and Ethiopia. This is on-demand, small-scale roasting for people who want the rare stuff — and their coffees turn up in national barista championships. They ship worldwide (free over 1kg). A splurge-worthy pick if you want some of the most meticulous, boundary-pushing single origin specialty coffee out there.
