The 2013 Cornerstone is a blend of 43% Cabernet Franc, 42% Merlot and 25% Cabernet Sauvignon; this is the first time the latter is not the dominant variety, since the other two varieties just looked so good. It was also the first vintage where winemaker Rudiger Gretschel used a berry selection table, whereas before he used just a bunch selection. Matured for 22 months with only the Cabernet in new oak and the Merlot in 2,500-liter foudres, it has a tightly wound bouquet with mint-tinged black cherry and raspberry preserve aromas. The aromatics clearly need another year to open. The palate is medium-bodied with grainy tannin and very well judged acidity there is a light tarriness coming towards the grippy finish that is very harmonious and long in the mouth. Give this 2-3 years in bottle.

The 2013 Capstone (also released under the Cornerstone label outside the United States) checks in as a blend of 43% Cabernet Franc, 42% Merlot and the rest Cabernet Sauvignon that spent 22 months in a mix of new oak (for the Cabernet Sauvignon) and larger oak foudres. It has a spicy, sandalwood, cedary character as well as beautiful black raspberry and blueberry fruits, plenty of dried herbs and graphite nuances, medium-bodied richness, firm tannin, and vibrant yet integrated acidity. This is an energetic, lively, nicely concentrated Bordeaux blend that’s loaded with character and will keep for 10-12 years.
This classical in style Bordeaux blend combines freshness with a real intense concentration showcasing the best of Stellenbosch. The nose presents a defined graphite minerality, with fresh perfumed red fruit layers of blackcurrant with hints of tobacco leaf and dried herbs. A wine which has lovely balance, with juicy tannins, adding structure and focus.
Blend: 43% Cabernet Franc, 32% Merlot and 25% Cabernet Sauvignon.
