I recently got to enjoy a 2015 bottle of The Chocolate Block. A 71% Syrah (Shiraz*), 15% Grenache, 8% Cabernet Sauvignon, 5% Cinsault and 1% Viognier blend. The 1675 barriques were produced entierly from Swartland fruit.
It has blackberry and red berry fruit aromas, also a little spicy. The Syrah and Cabernet Sauvignon give it intense tannins but overall, it is a fine wine and I love it and want to share it so I will get a bottle for my grandfather who like myself has an appreciation for red wine.
*Even though Syrah and Shiraz are genetically the same grape, the wines they produce can differ in style depending on the origins of the grape, this distinction is indicated by the different names. I also noticed that the 2012 bottle had 70% Shiraz instead of Syrah.
