With premox and other problems shortening the longevity of white Burgundy, I have been drinking up my last 2005s, a bit earlier than I would have done previously, and in the past year I have noticed a surprising change in the relationship between premier and grand crus in Chablis.
Take the example of Louis Michel’s grand cru Les Clos and premier cru Montée de Tonnerre. As Louis Michel is the benchmark for Chablis matured in stainless steel, the difference is a pure view of the effect of terroir on fruits, with no complications from different regimes of oak exposure.
Les Clos is always magnificent. For every producer it is the most reserved, steely, and mineral of any of his premier and grand crus. Just beyond Les Clos, separated from the band of grand crus by a small hollow, comes Montée de Tonnerre, always the best of the premier crus, and for some producers often pretty much up to grand cru standard.
I started drinking Louis Michel’s 2005s in 2009. Les Clos showed the house’s typical deeply textured structure, reflecting long maturation on the lees. Reflecting the warm vintage, it was a little richer than usual from the start, with stone fruits mingling with citrus.
Montée de Tonnerre was also a little richer than usual, but with the balance more in the direction of citrus, nicely textured under the fruits, with layers of flavor. Absolutely top notch for premier cru, but less depth than the grand cru.
Today things are different. Les Clos has become quite phenolic in the past year, and the sense of minerality has declined; it’s beginning to seem a little tired, and in a blind tasting I might place it farther south than Chablis. By contrast, Montée de Tonnerre is the absolute quintessence of Chablis: one sniff, and that cool, steely minerality shows that you are in Chablis. Fruits remain in the citrus spectrum, and there’s still some reserve on the finish. In a blind tasting I would place this as grand cru Chablis, and its steeliness might even make me think about Les Clos.
While the relationship between Les Clos and Montée de Tonnerre may have reversed, another grand cru, Vaudésir, has stayed truer to type. The textbook spiciness is overlaid by Louis Michel’s granular texture, stony rather than mineral, but with age the fruit spectrum is turning towards peaches and cream; phenolic hints intensify in the glass, following the path of Les Clos more slowly.
When the Crus were defined, the main distinction between them was reliability of ripening. But this was in a much cooler era: what ripened best in the 1930s may go over the top sooner in warm vintages in the new millenium. I suppose it all depends on what you mean by Chablis. If you want a rich white Burgundy, grand crus from warm vintages may fit the bill. If you want the historic saline minerality, premier crus may show more typicity.
The hierarchy of crus has always been defined, I think, in terms of wines tasted shortly after the vintage; it happens that the best age longer. That also may be changing with warmer vintages, with some of the grand crus richer and more delicious at first, but more likely to decline into blowsiness before the premier crus. How will the market react to this change, and will it be necessary to revise the classification of premier and grand crus?
