Montlouis-sur-Loire can match Vouvray for quality—and Damien Delecheneau, president of the appellation, proves it. Since taking over in 2016, he's pushed through an all-natural agenda (organic and biodynamic certified) and a region-wide ban on herbicides. His Chenin Blancs range from crisp and mineral dry wines to botrytic sweetnessses, all singing with the chalky purity of Loire terroir.
