London Calling Coffee

London Calling Coffee Company is based in Welwyn Garden City, Hertfordshire and positions itself explicitly as a wholesale-first roaster. Their stated sourcing approach involves working directly with farmers and using Q-grader certified tasters to assess and blend to specification, though the specifics of those farm relationships are not documented publicly.

The range covers over 10 blends across different styles including 100% Arabica, Fairtrade and decaffeinated options, available in 1kg catering and 250g retail formats. The business places particular emphasis on equipment and training support for commercial accounts.

They offer regular barista training sessions and equipment audits for wholesale customers as part of the ongoing service rather than as an optional extra. Equipment cleaning schedules and grind calibration are included in that routine support.
