There are several factors that contribute to making great Australian Shiraz:
Climate: Shiraz grapes thrive in warm climates, and Australia's hot, dry weather is well-suited for the variety. The Barossa Valley, McLaren Vale, and the Hunter Valley are all regions known for producing high-quality Australian Shiraz.
Terroir: The unique combination of soil, altitude, and other environmental factors can contribute to the distinct character of the wine. Shiraz grown in the Barossa Valley, for example, tends to have more rich, dark fruit flavours, while Shiraz grown in the cooler climate of the Yarra Valley may have more subtle, floral notes.
Winemaking techniques: The winemaking techniques used can also play a role in the final product. Shiraz can be made in a variety of styles, from rich and full-bodied to more elegant and refined.
Oak influence: The use of oak barrels during ageing can also contribute to the character of the wine, adding flavours such as vanilla, caramel, and spice.
Ageing: Australian Shiraz benefit from ageing for a few years to develop more complexity and character.
Overall, great Australian Shiraz is characterised by its full-bodied, rich, and dark fruit flavours, soft tannins, and complex aroma and taste profile.
