H-Block Shiraz Cabernet Sauvignon

2019 vintage

On the banks of the Greenock Creek, Otto Kasper planted a single block with two Cabernet parcels and a Shiraz parcel sitting side by side. This creates the perfect opportunity to make a single block of the great Australian blend, Shiraz Cabernet. Effectively, a blend of the best - our Clos Otto Shiraz and von Kasper Cabernet.

Shiraz (70%), Cabernet Sauvignon (30%)

(Due to volume scarcity, a 2 bottle limit applies)
