With respect to Jadot's more prestigious wines, the two offerings from the Duc de Magenta, which are made in the Jadot cellars, are both outstanding efforts. The buttery-scented 1989 Puligny-Montrachet-Clos la Garenne from the Duc de Magenta is slightly more stylish, but every bit as concentrated and spectacular, as the Chassagne-Montrachet-Morgeot. Although it is a more finesse-filled wine, both of these offerings are typical of the 1989 vintage in their blockbuster richness and dramatic depth of fruit. What they have that many 1989s lack is high acidity, which gives them an uplifting character, as well as focus and precision.Gagey considers the white burgundy 1989 vintage to be one of the three best years of the decade, comparable to 1985 and 1986. Jadot's white burgundies are among the slowest to evolve because in low acid years the malolactic fermentation is blocked to give the wines more aging potential. Not surprisingly, the 1989s are more backward, with slightly higher natural acidities than found among other white burgundies in the Cote d'Or. For that, as well as other reasons, Jadot's finest premiers and grands crus have 15-20 years of aging potential in 1989.The firm of Louis Jadot (they also own 115 acres of top vineyards), is probably the best run negociant firm in Burgundy. While the Jadot wines have always been excellent, in the last several years the extraordinary quality of the white wines has been matched by even more fabulous red wines. Next year I will report on the 1990 red burgundies, but readers might want to make a mental note that Louis Jadot's 1990s are of such a quality level that they are comparable to the wines from domaines such as Romanee-Conti and Leroy. This deserved achievement could not have been earned by a finer gentleman than Andre Gagey, who has run this firm with admirable conscientiousness and meticulousness for decades.Importer: Kobrand, Inc., New York, NY.
