Connected learning ecosystem
Academy, Lab and Atlas now have clear roles.
The Academy teaches concepts and methods. Coffee Lab turns them into interactive missions. Coffee Atlas adds geographic and origin context. Each service is deployed independently but uses the same RasoKarsa visual identity.
Coffee Lab
Practice 24 end-to-end scenarios from roasting and QC through blending, brewing, sensory judgment and customer service.
