The score for 2016 Chateau Cos d'Estournel St Estephe is 100 from Robert Parker and the tasting note - The 2016 Cos d'Estournel is blended of 76% Cabernet Sauvignon, 23% Merlot and 1% Cabernet Franc aged in 65% new and 35% two-year-old French oak for 15 months. Bottled in July 2018, it is deep garnet-purple colored and starts off a little closed and reticent, opening out slowly and seductively to reveal beautiful lilacs, rose hip tea, crushed stones and camphor nuances over a core of crème de cassis, kirsch, wild blueberries and mocha plus wafts of incense and wood smoke. The palate is simply electric, charged with an energy and depth of flavors that seem to defy the elegance and ethereal nature of its medium-bodied weight, featuring super ripe, densely pixelated tannins that firmly frame the myriad of fruit and floral sparks, finishing with epic length. Just. Magic. The score for 2017 Chateau Cos d'Estournel St Estephe is 98+ from Robert Parker and the tasting note - Composed of 66% Cabernet Sauvignon, 32% Merlot, 1% Petit Verdot and 1% Cabernet Franc, yields for the grand vin in 2017 were 43 hectoliters per hectare, and it was aged in 60% new oak. It came in at an alcohol of 13% and an IPT of 68. Deep garnet-purple colored, the 2017 Cos d'Estournel needs a little coaxing to unfurl, revealing beautiful expressions of preserved plums, boysenberries, blackcurrant pastilles and wild blueberries with hints of Indian spices, menthol, lilacs and mossy tree bark plus a compelling suggestion of iron ore. Medium to full-bodied, the palate has a solid backbone of firm, grainy tannins and well-knit freshness supporting the tightly wound blue and black fruits layers, finishing long and fragrant. This wine will need a good 5-7 years in bottle before it begins to blossom and should go on for at least another 40 years. I expect this wine to be a blockbuster of a head-turner when I come back and taste it at 10 years of age! The score for 2018 Chateau Cos d'Estournel St Estephe is 98+ from Robert Parker and the tasting note - The 2018 Cos d'Estournel is a blend of 74% Cabernet Sauvignon, 23% Merlot, 2% Petit Verdot and 1% Cabernet Franc, aged in 50% new oak barriques. The alcohol weighs in at just over 14.5%. Sporting a deep purple-black color, it needs a lot of swirling to begin to unlock a powerful nose of crème de cassis, stewed plums, wild blueberries and chocolate-covered cherries, followed by nuances of Sichuan pepper, star anise, tree and clove oil, plus a waft of charcoal. The full-bodied palate is densely packed with taut, muscular black fruits and earthy layers, framed by super firm, ripe, grainy tannins and seamless freshness, finishing very long and wonderfully earthy. A very impressive behemoth, this is going to need a good seven to 10 years to truly show its stuff and should drink for a good 40 years and beyond.
