One of Switzerland’s most known baristas and cafe owners. Originally from Japan, the co-owner of MAME in Zurich took the speciality coffee scene in Switzerland by storm since her competition beginnings in 2015. Although Emi did not win in Seattle—her first time on the world stage—she kept on competing every year after, alongside her life and business partner Mathieu Theis (a top-ranking barista himself and 2016 & 2018 Swiss Barista Champion).
In the years that followed Emi’s first Swiss win, the ambitious competitor went from Barista to Brewers Cup category. She took the third place at the Swiss Barista championship in 2016. Emi kept on working hard though and her efforts brought her third place in the 2017 Swiss Brewers Cup championship. 2018 was going to be Emi’s year.
