What type of grape variety is predominately used in producing Penfolds Grange?

Penfolds Grange is predominantly made from Shiraz, which has become a signature grape for this iconic Australian wine. The choice of Shiraz is integral to the wine’s character, providing a rich, bold flavor profile that reflects the warmth and terroir of the regions where the grapes are grown, primarily in South Australia.

Shiraz grapes contribute to the wine's depth, with dark fruit flavors like blackberry and plum, alongside spicy, peppery notes and a robust tannin structure. The winemakers also sometimes include a small proportion of Cabernet Sauvignon, but the primary focus remains on Shiraz, which allows the wine to express both sophistication and intensity. The use of American oak during aging further enhances the complexity, bringing out vanilla and toasty characteristics that complement the fruit flavors.

Understanding the grape variety's role in shaping the wine’s overall profile helps clarify why Shiraz is essential to Penfolds Grange. Thus, the dominance of this grape variety is key to appreciating the legacy and status of this renowned wine in the world of fine wine.
