You might have imagined that a commune like Margaux, tending to have lighter, famously more gravelly soils, would struggle in a hot year like 2009. It is clear that heat stress on the vines did lead to some difficulties with grape ripening getting blocked, but this so-called ‘hydric stress’ did also act to slow down a harvest that otherwise may have completely runaway in alcohol, conditions that would have led to a corresponding evaporation of acidity. Denis Lurton of Chateau Desmirail believes that water stress was key in the vintage, ‘It kept the ripeness in check in the warm weather. The conditions gave us so much control to make different choices and it’s all about the choices. That helped us make a lovely wine. ’
