The 2015 Oakville Reserve Cabernet Sauvignon is a fantastic showing from Groth. This was aged for 22 months in 100% new French oak, followed by over a year of additional bottle-aging before release. It begins with attractive aromas of dark currants, black cherries and crème de cassis, which are woven together with graphite, sweet spices, dusty minerals and hints of spring florals all developing in the glass. Medium to full-bodied, displaying nice overall structure and balance with notable depth and concentration. Flavors of ripe dark fruits, spices and graphite all continue to build on the palate and expand through the long, supple finish. While this is already offering wonderful appeal, it should also continue to develop nicely in bottle for quite some time.
