Weather conditions were very much in contrast throughout the whole of the Burgundian vineyard. After three years of mild winters, the winter snow in 1990-91 was very beneficial.
The mild, rainy spring allowed early budburst, thanks to an abrupt rise in temperatures in March. A light frost on 24 April, which at the Domaine affected part of the Bourgognes and the village appellation parcels, then blocked the vegetation.
Flowering stretched from mid-June to the start of July. Following a dry, sunny summer, storms broke out in August, bringing beneficial rainfall so that ripening developed favourably. Harvesting at the Domaine started only on 30 September, lasting until 7 October (Chevalier on the 4th under sunny conditions; the previous week had been very rainy throughout the Côte de Beaune - 100 mm). Thanks to this week of sunny harvesting and a large team (90 people), the harvest lasted only eight days. Excellent concentration (natural degrees of 12.5-13) and a small, concentrated harvest characterised the 1991 vintage.
