Champagne Tarlant "Zero" Brut Nature, NV

From Importer:

Benoît and Mélanie Tarlant are the 12th consecutive generation working the family land.

Winemaking:
Zero is made from equal parts Pinot Noir, Pinot Meunier and Chardonnay that are sourced from multiple parcels in the Marne Valley. The “zero” in this wine's name indicates it has no dosage. About 90% of the Tarlant production is bottled without dosage, a very rare and distinct stylistic choice for the region.
