Sus and Stef began working in the family business at the end of 2014. It was important for them that they set their own agenda and follow their own path, but remain respectful of their heritage. Production under the Rennersistas label began with the 2015 vintage, and just 5000 bottles were produced. he focus is on the vineyard, which, since 2009, has been certified organic and in 2018 became certified by Demeter for Biodynamic farming. They pick early, a key factor to these wines, which express such freshness. All go through spontaneous fermentation, and sulphur additions are only added post fermentation prior to bottling, if at all. All wines are unfined and unfiltered.
