💻 Coffee Technology & Digital Platforms

Taster Matrix (解味视界)

An online sensory evaluation data management system founded by Jiang Chengzhe.

Taster Matrix digitizes subjective coffee cupping and sensory assessments into structured, quantifiable data. Featuring SCA-compliant cupping input, standardized flavor wheels, and real-time collaboration, the system generates flavor radar charts and trend reports for roasters, coffee graders, and sensory analysis labs.

Cotrix

A coffee supply chain and inventory management platform.

Deeply integrated with Taster Matrix (similar to the synergy between Cropster and c-sar), Cotrix handles green coffee sourcing, physical bean properties (moisture, density, defect count), roasting curve profiles, and inventory control. Together they build a digital closed-loop from green bean parameters to final sensory evaluation.
