The Coffee Excellence Center is the leading Public Research Institution on coffee along the coffee value chain: from crop to cup.

The Coffee Excellence Center was founded in 2008 by Prof. Dr. Chahan Yeretzian and has ever since expanded its scope and expertise to become the leading public science, technology and innovation center on coffee. 

We believe that high-quality coffee can only be obtained with a profound and holistic understanding of the coffee value chain. Therefore, we are dedicated to state of the art research on coffee along the whole value chain. 

We aim to disseminate our coffee expertise via publications and in post-graduate education programs.
