An antipodean founder set up Volcano in 2010 to try and bring better coffee to the UK, and its grown from a coffee cart to a top-end roastery in Brixton. With the founder still involved and striving for continued commitment to ethical sourcing, Volcano underwent what can only be described as explosive growth when they became WeWork UK's coffee partner in 2015. Coupled with their commitment to the homeless charity Crisis, Volcano is one of the biggest and most well known specialty brands in the UK.
