Kenya Coffee School (KCS) – Advanced Roasting Certification Model
An Industry-Led, Africa-Centered Specialty Roasting Standard
1️⃣ Program Vision
The Kenya Coffee School (KCS) Advanced Roasting Certification is designed to produce:
- Elite specialty coffee roasters
- Data-driven production managers
- Sensory-calibrated professionals
- Roast profile engineers
- Sustainable value-chain leaders
This certification positions Kenya not just as a producer of premium coffee, but as a global roasting authority.
Aligned with international benchmarks such as the Specialty Coffee Association framework, but localized to:
- Kenyan high-density coffees (820–850 g/L target)
- Washed and honey process profiles
- Small-batch and commercial production realities
- Climate-resilient roasting models
