This is an extraordinary concept: a Champagne born from a perpetual reserve ('PR') that spans nearly three decades. The '90-18' signifies a base of older reserve wines, constantly refreshed since 1990, and topped with the vibrant 2018 vintage. The result is a wine of unimaginable complexity, with a profound tapestry of baked apple, roasted nuts, truffle, and a finish of seamless, endless power.
