On the eve of the 150th anniversary of the acquisition of Château Lafite by the Rothschilds, the teams faced major challenges due to capricious weather conditions. From December to July, heavy rain increased the risk of mildew and hail. Mid-July saw very high, sometimes extreme heat, which helped to restore the vines’ health and set up a great vintage. Compared to Lafite, Duhart-Milon’s terroir was drier in 2018 for the Cabernet Sauvignon, but the Merlot terroir is more clayey, resulting in two different responses to the conditions. The Cabernet Sauvignon suffered from a lack of water over the summer, but some rain on 28th August and 5th September helped to restore the grapes’ balance and for them to ripen correctly. The Merlot’s more clayey terroir proved to be particularly well suited to the vintage, enabling some of the finest Merlot ever seen at Duhart. a promising result for our Grand Vin, which always contains a considerable proportion of Merlot.
