The Dufour estate is located in the village of Landreville, in the Côtes des Bar. Charles Dufour learned about winemaking from his father, and then spent some time making wine in Australia and New Zealand. When he came back to Champagne, he helped convert the estate to organic viticulture, which was certified in 2010. Champagne Bulles de Comptoir # 4 Vinorama consists of an assemblage of Pinot Noir grapes, Chardonnay with a last but not least touch of Pinot Blanc, collected in 2013 from the base with the addition of “vin de reserve” of the years 2010 and 2011. No sulfites are added to this Champagne Extra Brut. Disgorged in January 2016 in limited quantities in 4 different labels.
