The Wynns Black Label Cabernet Sauvignon is one of Australia's icon wines with a 50 year history. It usually displays firm, sometimes astringent tannins. Therefore I always put it away for a number of years for the tannins to mellow. It is a curious situation, because the wine is high volume and sold in major liquor stores. It can be assumed most of this is consumed immediately, which is not ideal.
Yesterday, I opened a 2008 Wynns Black Label Cabernet Sauvignon. The wine opened with typical and true to the variety blackcurrant fruit. Some of it is overripe and quite dry, but the major issue with this wine is the hole on the mid-palate. There is nothing special in the finish. The overall mouthfeel improves somewhat after the wine has been in the glass for some time, but charming this wine is not.
If you want to know what can be a problem with a 100% Cabernet Sauvignon wine, and why many leaders in France, the US, and Australia blend it, try this wine.
