For the grand vin of Lagrange, grapes are hand-picked into small crates and then sorted both manually and by an optical sorting machine. Traditional Bordeaux vinification is carried out in 92 temperature-controlled stainless steel vats of varying capacities, thus allowing a separate vinification to respect the character of each plot and soil-type. Placing all or part of a given plot into its own vat also allows harvest at optimum ripeness.

Total vatting time, determined by tasting, varies from 16 to 28 days, depending on the tannic development in the fermenting wines. Temperature of fermentation never exceeds 28°C to guarantee preservation of the finesse and fruitiness. Selection of press wine is performed “barrel by barrel“ allowing a wider choice range during the blend tastings.

The wines are blended only a few months after harvest, to achieve a better harmonization of the tannins and plot origins. The wines are aged 20 months in French oak barrels, of which 60% are new, and racked every 3 months.
