Profile of Spro Coffee Lab Team and Vision
Founders and Head Roasters
The founding team brings together equipment engineering, green sourcing expertise, and competitive barista backgrounds. They prioritize roast profiling accuracy and farm-level relationships.
Operational Philosophy
Spro Coffee Lab operates like a lab, documenting variables such as batch weight, drum speed, and ambient humidity. This structured approach supports repeatable flavor outcomes and rapid troubleshooting.
Roasting Technology and Process Control
Equipment and Instrumentation
The roaster features high-resolution thermocouples and airflow controls that enable fine tuning of development time and charge temperature. Data is logged for every batch.
Profile Design Methodology
Roast profiles are built around target end temperature, rate of rise, and crack timing. Small iterative changes are evaluated through sensory cupping and statistical tracking.
Green Bean Sourcing and Quality Assessment
Origin Selection Criteria
Sourcing decisions weigh farm practices, mill transparency, and historical cup quality. Preference is given to lots with clear traceability and documented agronomic practices.
Incoming Quality Checks
Before roasting, each lot undergoes moisture analysis, density sorting, and visual defect inspection. Lots that fail internal thresholds are rerouted or blended only with explicit approval.
Brew Guidance and Café Integration
Recipe Development Framework
Baristas translate roast data into brew parameters, including grind size, dose, yield, and agitation pattern. Recipes are version controlled and linked to specific microlots.
Training and Calibration
Onsite calibration sessions align café equipment with lab reference standards. Barista practical exams ensure consistent shot preparation under varied conditions.
Key Takeaways and Recommended Practices
- Prioritize traceable micro-lots with clear processing details.
- Maintain roast logs and cup consistently to refine profiles.
- Standardize green bean preparation for repeatable results.
- Align brew recipes with roast development characteristics.
- Use data-driven adjustments rather than intuition alone.
