Sweven roast their own, sourcing competition-circuit lots that rarely make it into a cup you can walk in and order: Geisha, Sudan Rume, Typica Mejorado, Sidra. The highest-ceiling roastery cafe in the South West.
A working Southville roastery with four named single origins and the flavour vocabulary to back them up. Buy a bag of the Ethiopian; the floral tea and lime notes hold at home.
Boona Boona roasts on-site, so the beans in your cup were roasted this week. The address is an industrial unit in Bedminster, which is either a deterrent or the whole point.
