My latest pickup from Garagiste had 2 different years of this puppy ready to go today, so I opened up the 2004 (being the most mature of the bunch) and had a go with my surf + turf (New York steak and Alaskan Black Cod). I had high hopes since this is a Ben Glaetzer wine, and he has had the Midas touch with Shiraz.
This was an excellent choice. It is a limestone coast wine, and you can taste it. It is very heavy and full bodied (my wife could not handle it) but balanced. The tannins are smooth and match the rest of the wine well at this age. If you like the Mitolo GAM then I think that you would certainly love this.
Now I have two of the 2004 and the 2005 left, and I am happy to have them. Hopefully I can resist drinking them for a while - I am keen to see how this evolves in the bottle. Highly recommended.
