Dolní Kounice (Czech Republic) The Dva Duby winery is a small winery in Dolní Kounice, in South Moravia, on the border between the Czech Republic in the south and Austria in the north. This is an area with a vocation for wine, which here, in ancient villages, has been famous for centuries for the production of wine, especially red (among the indigenous grape varieties of these lands are St. Lawrence and Blaukfränkisch). The goal that Jiri Sebela set himself 10 years ago when he began his production, is to transfer into each bottle the richness of a very special terroir, formed in the Proterozoic period (over 2 billion years ago). The wines are produced without the use of systemic treatments, herbicides, and since 2007 not even copper. The natural approach continues in the cellar, where the wines are aged in oak and acacia barrels, without any other additives.
