About Jiang Chengzhe
From Chemistry Lab to World Roasting Stage
I graduated from Taiwan National Tsing Hua University with a degree in Chemistry (featured by NTHU Alumni Center). Coffee isn’t mysticism to me — it’s chemistry, physics, and a creation that can be precisely controlled through science.
In 2013, I won the first Taiwan Coffee Roasting Championships and went on to compete at the inaugural World Coffee Roasting Championship in Nice, France, earning the position of Runner-Up — the highest placement ever achieved by an ethnic Chinese competitor at a world coffee championship at that time. (WCRC official archive, registered as Chen-che Chiang)
In the field of commercial and technical innovation, I served as the recipe designer for HWC Coffee (Roaster for China Airlines’ presidential flight serving state visits), crafting the classic signature blends “Dark - Power Drum” and “Volo - Sacred Tune”. In addition, I am committed to the digital transformation of the coffee industry and founded the coffee digital technology platforms Taster Matrix & Cotrix.
