Founded in 1981, Roederer Estate is nestled in Mendocino County's cool, fog-shrouded Anderson Valley. As the California outpost of Champagne Louis Roederer, Roederer Estate builds upon a centuries-old tradition of fine winemaking. Before a great sparkling wine can be produced, fine wines must be created. The House of Louis Roederer has used the traditional elements of the méthode champenoise process to create the finest champagnes since 1776. Today, these age-old techniques are combined with leading-edge technology at Roederer Estate. It Begins in the Vineyards... Roederer Estate grows 100% of the grapes used in its sparkling wines. This control assures the quality of the fruit that goes into the winery's fine bubblies. The time between the flowering and the harvest is exactly 100 days – just as it is in Champagne. Many wineries harvest after only 90 days or sooner, but Roederer believes that the best fruit is allowed to mature slowly. This longer maturation period is made possible in the Anderson Valley by the cool, foggy climate.
