Maria and Michael who live and work in Štajerska Slovenija make for one half of Gross & Gross. Their winery and the organically cultivated Vino Gross vineyards are located in Maribor and Haloze, though in Haloze one would need to call them wine terraces. As the area is so steep, terraced cultivation is the only option. What is more, Maria and Michael only gently support the vinification process, merely lending a hand when it is truly needed.
