Rousseau's 1991 Clos de la Roche is the toughest and most problematic wine to evaluate. Unquestionably, it possesses power and body, but it is closed, and the tannins taste astringent. For now, I have given this wine the benefit of the doubt, but it requires monitoring for the next 3-4 years. Rousseau, one of the reference points for great burgundy, appears to have made 1991s that are even richer and more profound than his 1990s. His production was one-half of normal, so these wines will be difficult to find. Rousseau normally excels with his three top cuvees - Gevrey-Chambertin-Clos St.-Jacques, Chambertin-Clos de Beze, and Chambertin, but the lower level wines often lack concentration and intensity. That is not the case in 1991. Kudos to Rousseau for producing his finest portfolio of wines in over two decades! Importer: Frederick Wildman & Co., New York, NY.
