Louis Roederer's cuvées are primarily crafted from three noble grape varieties: Pinot Noir, Chardonnay, and Pinot Meunier. Pinot Noir, the House's signature grape variety, brings structure, depth, and complexity to the wines, while Chardonnay contributes freshness and elegance, and Pinot Meunier, roundness and softness. Each grape variety is vinified separately, plot by plot, to better preserve the expression of each terroir before the final blending.
