Our first taste was courtesy of a small, unpretentious family-run producer, Leclerc-Mondet, in the village of Trelou-sur-Marne. The ruggedly tall son-of-the-family, Fabien, was on hand to take us around the vineyards, and then through the entire winemaking process, from handpicking the varietals — Chardonnay, Pinot Noir and Pinot Meunier — that are blended into Champagne, to the techniques of turning the bottles and disgorging the natural sediment. Known as méthode champenoise, this is what gives Champagne its sparkle.
