100% Chenin Blanc. Pinon makes two brut sparkling wines, both of which are made with the méthode champenoise and from estate parcels of flinty clay soils over the classic Vouvray tuffeau (soft chalky limestone). The later-harvested,top-quality fruit goes into this zero-dosage bottling to allow for a better balance in the final wine. The vines for both average 45 years old and have been certified-organic since 2007. The fruit is harvested manually and goes through a rigorous three-step sorting process. The clusters are gently and slowly pressed whole,and juice flows by gravity to tanks below. Fermentation is spontaneous with indigenous yeasts in tank and lasts 4 to 6 weeks. The wine is racked into old tonneaux and steel tanks for 2 to 3 months of aging on the fine lees. It is then lightly filtered and bottled for its second fermentation.
