Brokenwood make some of the most prestiges wines from the Hunter Valley. Every bottle of old Graveyard Shiraz or any of their semillons that I've had have been brilliant. The Graveyard looks especially stunning after the 10 year mark so if you have any just leave them alone.

Tasmania has to be considered at the cutting edge of cool climate wine regions which makes for risky business in the wine industry yet some how Stefano turns out beautifully crafted and exquisite wines each year.
