"Loud Mouth roast on-site, sell direct, and have named their coffees like Jaw Dropper and Proper Gobby with appropriate conviction. The espresso is the point; the bag of beans is the souvenir."
Loud Mouth Cafe, Black Swan Arts, 2 Bridge St, Frome BA11 1BB, UK
Loud Mouth roasts its own coffee in a unit on the edge of Frome. Worth the drive; buy a bag while you're there.
Round Hill Roastery coffee, served in the yard of a working classic car restoration shop on the edge of Frome. The sourcing is deliberate and the setting earns the detour.
Clifton Coffee Roasters beans in the back of a working bike workshop on Bath Street. The homemade food earns its own return visits.
