April 2017 - Reviewer : Neal Martin. The 2015 Chocolate Block is a blend of 71% Syrah, 15% Grenache, 8% Cabernet Sauvignon, 5% Cinsault and 1% Viognier. Previous vintages have been Western Cape, this being the first W.O. to be Swartland. It has an attractive blackberry, cedar and dark chocolate scented bouquet, strangely the Cabernet Sauvignon making a big impression upon the Syrah. The palate is medium-bodied and quite austere compared for this label, tightly wound at first with a slightly attenuated finish. I was just seeking more substance and body on the finish that tapers off a little quickly.
