Clos Roche Blanche Touraine Sauvignon Blanc 2010
The soil is poor, mainly clay with flint over a limestone subsoil. The varietals grown are Gamay, Cot (or Auxerrois, the grape of Cahors) and Sauvignon Blanc. Roussel and Barouillet keep yields low by maintaining old vines, using organic fertilizers in moderation and growing grass between and plowing under the rows.
They converted the vineyards to organic farming over the past three years and the 1995 vintage bears the official "organic agriculture" accreditation. The vines are treated with copper and sulfur solutions, and plant decoctions (a mix of nettles and other herbs) used in bio-dynamic viticulture.
Neither Catherine nor Dider has studied oenology or viticulture. They both learned their trade in the vineyards and the cellar, searching for methods and techniques to make wines of exceptional character in an appellation of modest reputation.
Stretching east along the steep banks of the Loire River, Touraine is a major part of the Middle Loire. Soil variations of clay, sand, tuffeau and gravel throughout its subregions support both white and red varieties. Chinon and Bourgueil remain the source of Loire’s finest Cabernet Franc; various styles of the most outstanding Chenin blanc come from Vouvray and Montlouis.
Capable of a vast array of styles, Sauvignon Blanc is a crisp, refreshing variety that equally reflects both terroir and varietal character. Though it can vary depending on where it is grown, a couple of commonalities always exist—namely, zesty acidity and intense aromatics. This variety is of French provenance. Somm Secret—Along with Cabernet Franc, Sauvignon Blanc is a proud parent of Cabernet Sauvignon. That green bell pepper aroma that all three varieties share is no coincidence—it comes from a high concentration of pyrazines (herbaceous aromatic compounds) inherent to each member of the family.
