The Reyneke estate now includes a total of 37 ha (91 acres) with vines growing on 30 ha of them and animals such as cows, ducks, chickens and guinea fowl on the rest. Since 2004, when biodynamic techniques were established in the vineyard, the pH of the soils has gone from 5.5 to 6 or 6.5, so the pH of the wine has gone down and the total acidity has gone up.
A classical Bordeaux style blend combines freshness with real concentration, showcasing the best of Stellenbosch.
An intense sorting process of bunch & berry selection ensures that only the best fruit end up in the Nomblot concrete fermentation tanks. The wine matures for 18 months in French oak barrels, of which 30% are new and 70% second and third-ﬁll barriques.
The Cornerstone has always been an important wine within the Reyneke range, with the proceeds of this wine helping farm workers and their families with education, housing and retirement annuities. At Reyneke we believe that the workers are the cornerstone of the business, which is an integral part of the holistic and biodynamic principles, that Reyneke follows.
Made from a blend of 54% Cabernet Sauvignon, 32% Cabernet Franc and 14% Merlot, the 2017 Cornerstone displays a dark ruby core with a lighter ruby edge. Aromas of crème de cassis, dusty plum and blackberry skin, plus elements of sage, purple flowers and juicy tobacco waft out of the glass. Medium to full-bodied, this organic wine displays a balanced structure of lifting tannins before offering up elements of rosemary blossoms and black cherry skin with a persistent, dusty edge and a long, lingering and textured finish that will remain food friendly for the next decade.
