This is an important wine in the St Hallett lineup, and it's a blend of two areas within the Barossa Zone: Barossa Valley (51%) and Eden Valley (49%). The plantings range from 1963 through to the 1850s, and the 2017 Old Block Shiraz is a great example of how old vines cushion the wine from the impact of the vintage. This is concentrated, set into a medium-bodied (plus) frame, and shows an array of red fruits and exotic spice. It's a cracking wine that manages to hold onto traditional and classical, but it also taps into modernity in the shape of its tannins and its flow of fruit. Super smart.
