Château Le Coteau is a small estate in Margaux that neighbours Rauzan Ségla, Giscours and Issan. Its 12ha is planted with 65% Cabernet Sauvignon, 25% Merlot, 8% Cabernet Franc and 2% Petit Verdot. No herbicides or insecticides are used. The winery’s 13 stainless steel tanks allow the different plots and varietals to be vinified separately. Ageing is in French oak barrels, one third of new wood, for 12-16 months.
