Deep garnet-purple colored, the 2015 Cabernet Sauvignon Volcanic Hill opens with dusty soil, cloves and fragrant earth scents with a core of red and black cherry preserves, plum pudding, blackcurrant cordial and mocha with touches of cedar chest and potpourri. Very big, rich and decadently fruited, it fills the mouth with powerful fruit and a taut frame of fine-grained tannins plus great freshness, finishing long and perfumed.- Lisa Perrotti-Brown (10/2018)

The 2015 Cabernet Sauvignon Volcanic Hill is the most savory and mineral-driven of these three Cabernets from Diamond Creek. Graphite, gravel, crème de cassis, lavender, menthol and plum are all finely sketched. The Volcanic Hill shows a good deal of the nuance that makes wines from this part of the estate so compelling, but in a far more approachable style than I can recall encountering previously. I would prefer to give the 2015 a few years to develop a bit of aromatic complexity, but opening a bottle on the young side is hardly a crime.- Antonio Galloni (12/2018)
