Roederer Estate's winemaking style is based on two elements: ownership of its own vineyards and the addition of oak-aged reserve wines to each year's blend or cuvée. All the grapes for the Anderson Valley wines are grown on the Estate. Oak-aged wines from the Estate's reserve cellars are added to the blend, creating a multi-vintage cuvée in the traditional Louis Roederer style. Only the cuvée (first pressing of 120 gallons/ton) is used; no premiere or deuxieme taille. The fermentation takes place in high-grade stainless steel tanks at 65 degrees Fahrenheit. Zero to minimal malolactic fermentation is used in order to ensure the wines age well and retain the fresh, precise and well-defined style that is one of the characteristics of Roederer Estate wines.
