The 2017 Cos Labory is deep garnet-purple colored and scented of blackberry pie, cassis and pencil shavings with touches of violets, garrigue and mossy bark. Medium to full-bodied with a firm frame of ripe, grainy tannins, it has lovely freshness and impressive length.

The 2017 Cos-Labory has a commendable bouquet with clean, crisp aromas of blackberry, smoke and light tobacco scents. There is no greenness here, a trait that can spoil some vintages of this Saint-Estèphe. The palate is medium-bodied with supple tannin, a fine bead of acidity, plenty of ripe brambly black fruit with a sense of mineralité on the finish. Hey...is this the moment when Cos-Labory produces a great wine? Looks that way here. I look forward to re-tasting this once in bottle and will keep my fingers crossed. - vinous.com, May 2018

Rather sophisticated for the vintage, this is velvety and linear with fresh acidity, firm tannins and a juicy finish. - jamessuckling.com, April 2018

The 2017 Cos Labory is laced with inky blue/purplish fruit, gravel, smoke, licorice, lavender and crushed rocks. This is the first vintage to incorporate a dollop (5%) of Petit Verdot, which seems to add attractive elements of darkness and savoriness. Proprietor Bernard Audoy adds that harvest was over by October 2, which is earlier than the first day of harvest in 2016. - vinous.com, May 2018

Deep crimson. Cassis, cedar and graphite on the nose. Dark, dry and layered on the palate. Dry, subtle finesse. Elegant and with an attractive mineral aftertaste. - Julia Harding, jancisrobinson.com, April 2018
