Hovering over the appellation is the best known, most expensive and most baffling domaine, Nicolas Joly, among whose holdings is Savennières’s most hallowed terroir, the Clos de la Coulée de Serrant. Mr. Joly may be best known nowadays as the guru of biodynamic viticulture. Biodynamics has come to be widely accepted (though fervently dismissed as well), but Mr. Joly holds other beliefs that may be equally or even more controversial. For example, while all wine producers wish to harvest ripe grapes, what constitutes ripe is subjective. Mr. Joly seeks grapes that have begun to shrivel and, he hopes, develop botrytis, the noble rot that is an essential component of wonderful sweet wines but not always desirable in dry wines. Fermented until dry, the Joly wines are typically high in alcohol, 15 percent or more as against the more typical 13 to 14.5 percent. Mr. Joly also recommends the extreme measure of decanting his wines two days in advance.
