2000 Leasingham Bin 61 Shiraz (Clare Valley)
This was the only one served blind & it had me flummoxed. It was rather gamey, but also had a lot of candied fruit with zero acid or backbone. I was only able to muster a weak "new world" guess. It really seemed like a brett infection run amuk.
2002 Turley Charbono Tofanelli Vineyard (Napa Valley)
While there was enough acid in this wine to share with the Bin 61, it was not volatile (surprise). The aromatics were actually quite nice, with lots of fresh, crushed raspberries & some spice. Everybody liked this wine to some degree, though I did find the finish to be acidic and clipped.
2006 Rosenblum Heritage Clones Petite Sirah (San Francisco Bay)
I had no idea they could grow grapes in the bay.

2004 Ridge Petite Sirah Dynamite Hill (Spring Mountain, Napa Valley)
The star of the show both in intent and in execution. This is brooding, monolithic, tannic and dense as a dwarf star. The sheer amount of material buffers the tannins, making this surprisingly drinkable, but it still needs a lot of time to come into its own.
