It was the development of effective frost protection in the early 1960s that encouraged today’s increase in the vineyard area of Chablis, which has not been without controversy. The seven climats of Chablis Grand Cru total 105 ha and are all on one slope facing south west just outside the town. They are Les Clos, Blanchots, Bougros, Vaudésir, Valmur, Preuses, and Grenouilles. There is also, in true Burgundian fashion, an anomaly. The tiny vineyard of La Moutonne is partly in Vaudésir and partly in Preuses, but for some illogical and doubtless bureaucratic reason, an official inao decree confirming its status as a grand cru has never been issued, even though its wines certainly demonstrate that it qualifies.
