(Please see my overview of the 2018 vintage in the Côte d’ Or here.)
Frédéric Mugnier said that harvesting began with the Bonnes-Mares on 28 August -- the parcel had suffered from drought, receiving no rain from July until October. The harvesting for the other Chambolle vineyards began on 1 September, and the Nuits were harvested on 8 September. He said that quantities were good. Alcohols for the Chambolle wines were between 13º and 13.5º; for the Clos de la Maréchale (which had suffered from the hail over the summer, with half the crop lost in red, a little less in white), they are 14º to 14.5º. Some malo-lactic fermentations went quickly, others not.
He noted that over the last five years, acidities have been good despite high sugar levels (which correspond to high alcohols). This is the effect of global warming, and it will be necessary to rethink standard rules in dealing with this changed environment.
