The superb terroir of the Grand Clos de Léoville Las Cases triumphed over the challenges imposed by the contrasting weather of 2019. After a mild winter and a cool spring, summer of 2019 was dry and hot, causing moderate water stress for the vines. From August to the harvest, the significant thermal amplitudes between the night and the day allowed for a slow ripening of the grape varieties, while also maintaining great acidity levels.
