As Dipl.-Ing. (FH) I worked in sales and marketing for many years, with many contacts in other European countries. Sustainable nutrition, especially with wine, is my special topic. That's why I'm involved with PIWI International and Slow Food and I want to convince as many wine drinkers as possible of PIWI's.

I have been working with PIWI vines all my life since 1985. I was a member of a team that imported prospective new varieties from European research institutes and also dealt with the new varieties of PIWI grape varieties. Since 1996 I have been cultivating 2.3 hectares of PIWI varieties organically and offer NATURVIN wine. My task and also the goal is to establish "PIWI - Czech Republic" in 2021!
