H-Block Shiraz Cabernet Sauvignon

2016 vintage

2021 Cellar Release

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 and thus created the perfect opportunity to make a single block of the great Australian blend, Shiraz and Cabernet. Effectively a blend of Clos Otto and Von Kasper!

(Due to volume scarcity, a 6 bottle limit applies)
