Some have said the Romas Vineyard in Blewitt Springs, North-East McLaren Vale, is Australia's greatest Grenache vineyard. The bush vines are now 99 years old. The vineyard is very steep, and the yield a very low 0.5t/acre.
I am tasting the 2012 Clarendon Hills Romas Grenache. The wine has a very dark colour and a deep black fruited aroma.
The very ripe raspberry fruit delivers a big mouthfeel on the palate. There is a sweet core, but it is actually dominated by alcohol and coarse, dry tannins. If you know Torbreck's Les Amis, this is the McLaren Vale equivalent. I find the wine not particularly refined, and the alcohol starts to burn the mouth on the finish.
This wine clearly makes a statement, and it is far removed from delicate, sometimes sweet Grenache. Some will like it, but this wine is too much on steroids for me.
