Cabernet Sauvignon McLaren Vale South Australia
Coppermine Road is named after an avenue, very near the d'Arenberg property which runs parallel to the finest block of Cabernet Sauvignon vines to be found anywhere in McLaren Vale. The precious grapes are descended largely from a curious and near extinct unnamed clone which yields no more than a single tonne per acre because of its very poor setting ability and tiny berries. The quality of the fruit however is far superior, with wonderful violet and blackcurrant aromas, great acidity and long but intense, finely grained tannins.
Walking the vineyards and tasting grapes, Chester Osborn determines the ideal picking time for each individual row. Small amounts are passed through the Demoisy open mouthed, rubber toothed crusher before transfer to five tonnes headed down open fermenters. The vats are treated to a course of foot treading, boots on, two thirds of the way through fermentation. When tannin extraction is just right the wine is basket pressed and transferred to a mixture of seasoned and new French and American oak barriques for the completion of primary and malolactic. Barrel ferments are aged eighteen months on lees to keep the wine fresh while also reducing oak influence.
Deep dark, almost black. Black currant leaf, violets and cigar box with an interesting twist of cooking spice and mustard seed. A palate of sweet blackcurrant and mulberry fruitiness that builds as the wine continues to evolve in your glass. The initially cedary tannins, start early and give the wine an incredible line. An intriguing fennel note accompanies the chalky tannins that are picked up on the finish, lingering and long.
