Mouthwater Coffee Company is the latest venture for Feldon, a self-taught barista who learned to make a strong brew by watching YouTube videos. Andrew Feldon, standing, has a coffee and a chat to Lyndon Tongs and his son Corban Tongs at Feldon’s new coffee cart on Tremaine Ave. After realising he was not cut out to be a chef, Feldon sunk his teeth into the coffee industry and ran a coffee cart in Sanson between 2006-2011.
