Diam. Didier Defaix tells us he has worked with the same grower family for twenty years and although the vineyards are not organically certified, the grower ‘works like us’, (that is to say he’s very happy with the quality he receives). The Montée de Tonnerre is drawn from old vines in Chapelot, which form 20 hectares of the vineyard on a similar southeast-facing aspect to the neighbouring Grand Crus. The vineyard’s iconic grower is, of course, Raveneau, although Moreau-Naudet, Billaud-Simon and others all farm vines in this prestigious lieu-dit. This cuvée is fermented wild, entirely in used barrels (one to five years old) with regular battonage. The wine is bottled after 12 months.
