Champagne Roederer is among the best-known producers of Champagne AOC sparkling wines. It has organic certification for part of its vineyard (details below).
Organic certification: 116 hectares out of 240 ha will be officially certified organic during the 2021 harvest (Sophie Constanzer 2020).
Organic costs: “In 20 years, we have doubled our fleet of tractors [to plough out weeds rather than use herbicide with] an increase of 20 to 30% in the number of working hours”, Johann Merle, cellar master is quotes as saying (Sophie Constanzer 2020).
