The last time I tasted Chateau Libertas 1940 was on the occasion of the brand’s 80th anniversary in 2012 when the information to hand suggested that its constituent parts were “predominantly Cabernet Sauvignon but including Cinsault and some of the Port varieties” while the alcohol was given as 14.93%. My tasting note at the time was as follows: “Decaying forest floor, orange rind and caramel on the nose. Rich, thick textured and mellow on the palate. Not unlike Tawny Port.”
