This crémant has the same base wine as the extra brut classic, 50% Chardonnay, 40 % Pinot noir, 10% Poulsard & Trousseau, fermented for 60% in barrel and all of the fruit from the 2016 vintage. This wine is unfiltered. The one thing that changes is the liqueur de tirage.
It is called “Indigène” because the liqueur de tirage, which triggers the secondary fermentation, comes from Stéphane’s own vin de paille so there is no selected yeast or cane/beet sugar used. The vin de paille is harvested in October, then laid up in the attic where it is warm and dry in order to concentrate the juices. Come January they press these bunches and put the must in a warm room in order to get fermentation started. Stéphane slowly adds this fermenting vin de paille to some base wine in order to get the liqueur de tirage going and then only once yeast activity is going strong he adds it to the still wine for the secondary fermentation to take place. 15 months on the lease before being disgorged in spring 2018. – Camille Rivière Selection
