On our roasters, The use of innovative technologies and advanced systems are all geared towards one objective: to let users freely express their interpretation about coffee while making sure that the same results can be recreated time after time.

Our company is named after the mineral rubasse, a crystal that’s clear, red, and pure, giving warm and clean impressions just like the flavors created by our cutting-edge coffee roasters.

The logo design bears the clean lines of a cut gem, while also resembling the shape of a coffee bean. The three colors correspond with the color of the beans during different stages of roasting under our unique center-placed near infrared heat source.

    William Cheng, the founder of Rubasse, is a specialty coffee lover. During his Ph.D. degree in Physics at National Taiwan University, he was very familiar with Rapid Thermal Annealing which is widely used in the semiconductor manufacturing process and was fascinated by the precise and rapid heating that near-infrared brings. Thus, he started researching how to combine near-infrared and coffee roasting together in 2013. He spent almost 3 years investigating physical methods which can highly improve energy efficiency and programming automatic systems and PID algorithms by himself. That is how Rubasse was born. Epoch-Making intelligent roasters rewrote how we roast coffee in the past. Rubasse NIR Digital Roasters provide coffee roastery a better solution for fresh, low cost, and consistent coffee roasting. In 2019, Rubasse becomes the largest market share in Taiwan's automatic shop roasters.
