M&M-Bioweine was founded in 2008 by Mike and Maria Kanzso-Rüdisühli. Together with their family members and friends, they cultivate plots in the Vispertal, Visperterminen and St. German on the Lötschberg Südrampe. The entire vineyard is cultivated and cared for according to federal organic guidelines. Their winery is the first certified organic winery in the Upper Valais and they specialize in old grape varieties from the Upper Valais and their organic cultivation.
After training as a winemaker and master winemaker, Mike Kanzso gained experience at various wineries around the world. These include Davaz (Fläsch), Stonyridge (New Zealand), La Torre Vini, Marcel Zanolari (Veltlin/Poschiavo, biodynamic), Manincor (Kaltern, South Tyrol, biodynamic), Chanton-Weine (Visp) and Cave du Rhodan (Salgesch).
Maria Kanzso-Rüdisühli grew up on a farm in the St. Gallen Rhine Valley with 11 siblings and learned about vegetable growing from scratch. After completing her commercial training, she went on to train as a medical masseuse and Qigong teacher. At the same time, Maria was one of the best sport climbers in Switzerland, a member of the national team and an active World Cup climber. They still explore the numerous crags in Valais today, as long as their work in the vineyards allows it. In the meantime, Maria has also trained to become a specialist in handling the vines and working in the cellar. She is also responsible for the beautiful garnishes that are served at tastings at the winery, as they come from their own garden.
