Compare the Gatt wine with this single vineyard Shiraz by Yalumba. It is clearly marked as coming from the Swingbridge Vineyard near Craneford in the Eden Valley region of the Barossa. A little card gives some detail about this experimental wine from 90 year old vines.
This 2009 Yalumba Swingbridge Vineyard Shiraz is quite unusual. It has an extremely intense blueberry flavour, more so than I have probably ever come across. It is a fragrant wine with considerable white pepper on the palate. This should be a great wine, but unfortunately there is not much complexity to hold the initial interest, and the finish remains quite fruity. On the other hand, the wine is a good terroir expression of Eden Valley Shiraz, not heavy and more peppery than Shiraz from the Barossa Valley.
