Milan has been practicing organic viticulture on approximately 17 hectares of loess and clay soils in southern Moravia, near the Austrian border, since 2009. He vinifies exclusively with wild yeasts, spontaneously fermented, without filtration or fining, and with minimal sulfur – always following the motto "Wine from grapes, nothing more." The grapes come from indigenous varieties such as Riesling, Neuburger, Grüner Veltliner, Pinot Noir, Zweigelt, and Blaufränkisch. He uses large, used wooden and acacia barrels as well as stainless steel tanks, and avoids additives.

Nestarec is a permanent member of the Czech Authentista movement and is internationally regarded as a driving force in the natural wine scene from Moravia. The result is vital, terroir-related wines with a high recognition value – fresh, clear, precise and always full of energy and personality.
