Technical Committee Members

Ed Seguine created craft chocolate from bean-to-bar for over a third century.  His passion for the diversity and purity of flavour in cacao led him to chair the ICCO Fine and Flavour Panel (now Chairman Emeritus), chair the Cacao of Excellence Technical Committee, and chair the Fine Chocolate Industry Association-Heirloom Cocoa Preservation Sensory Committee. His pioneering vision and dedication made a lasting impact on the cacao sector worldwide.

“While we work to develop sustainable supply chains we must not lose sight of the reason that cocoa exists—to provide flavour that delights and creates memories. We experience chocolate from some of the finest, craftsmanship produced cocoa that the world has to offer—and celebrate the craft of the men and women producers who provide this Food of the Gods. “

Ed was one of the creators of the Cacao of Excellence Programme in 2008 and was the chair of the Technical Committee from 2009 to 2024. His legacy continues to inspire our work.
