Specialty Roaster
Kaldera S7
The shop roaster that behaves like lab equipment.
From $18,400 · lead time 10–14 weeks
The S7 is where most Kaldera roasteries begin. A hand-balanced 7-kilo drum, ceramic combustion and full closed-loop control give a café-scale roaster the repeatability we usually reserve for the factory floor. Save a profile once and run it identically for years.
