Anselme Selosse is one of the pivotal figures in the modern history of Champagne. Selosse’s meticulous attention to detail in the vineyards and bold wines inspired a whole generation of younger growers, some of whom spent time working alongside him, and others who were captivated by a vision of Champagne as a wine that is, first and foremost, born in the vineyard. This recent tasting provided a remarkable opportunity to check in on a number of disgorgements of the flagship Substance going back to the early days.
