Shiraz, a dark-skinned grape variety, has a storied legacy that weaves through continents, cultures, and centuries. Primarily associated with the Rhône Valley in France, where it's known as Syrah, and Australia, where it goes by the name Shiraz, this versatile grape has carved out a reputation for producing some of the world's most robust and flavour-intense red wines.
The grape's journey is as deep and complex as its wines, with a history that is often romanticised, linked to the ancient city of Shiraz in Persia. Although DNA typing has debunked the myth that the grape originated in Iran, the tale adds to the grape's mystique, reflecting the rich, oriental tones found in its flavours.
In France, Syrah is the noble grape of the northern Rhône, the cornerstone of powerful, age-worthy appellations such as Hermitage, Côte-Rôtie, and Saint-Joseph. Its expression in these terroirs is often solitary, showcasing the varietal's potential for elegance, structure, and depth. French Syrah typically reveals notes of blackberries, smoke, and various spices, with a characteristic black pepper accent. It's here that Syrah shows its ability to reflect terroir, producing wines that vary dramatically with changes in climate, soil, and winemaking practices.
On the other side of the globe, the sun-drenched landscapes of Australia have embraced Shiraz as their flagship grape. The Australian Shiraz embodies a bolder, more fruit-forward style. It thrives particularly in regions like Barossa Valley, McLaren Vale, and Hunter Valley, where the warmer climate imparts a ripe, jammy quality to the wines. These are bold, full-bodied reds with a higher alcohol content and flavours of dark fruit, chocolate, and, in some cases, a hint of eucalyptus or mint.
The character of Shiraz can vary significantly with the winemaker's intentions. Old World techniques often emphasise the grape's potential for finesse and longevity. These wines are frequently aged in oak, which contributes to their complexity, adding layers of vanilla, toast, and smoky flavours. In contrast, New World winemakers may choose to highlight the varietal's fruitiness, often resulting in more accessible wines that are ready to drink at a younger age.
Another factor contributing to the diversity of Shiraz wines is the vine's vigour and adaptability. It's a hardy varietal capable of thriving in various soil types, though it shows a preference for well-drained, rocky terrains that stress the vine and intensify the fruit's flavours. Shiraz grapes tend to have thick skins, which contribute to the deep colour of the wines and provide ample tannins, making them suitable for ageing. These tannins, when well-managed, lend the wine a smooth texture and structure that underpins its powerful fruit profile.
Shiraz has also played a central role in the development of winemaking techniques, such as co-fermentation with a small percentage of Viognier, a white grape variety. This technique, often used in Côte-Rôtie, can enhance the wine's aroma, stabilise its colour, and soften the tannins, leading to a more delicate and aromatic profile.
In the vineyard, Shiraz's versatility allows for a range of styles even within a single region. For example, in cooler areas, the grape can produce medium-bodied wines with higher acidity and more restrained fruit, often with a noticeable pepper note. In contrast, in hot climates, the grape will yield full-bodied wines with lower acidity and an abundance of ripe, sometimes sweet, fruit flavours.
Beyond France and Australia, Shiraz has found homes in South Africa, where it's known for producing spicy and somewhat smoky wines, and in California, where it contributes to the state's rich portfolio of hearty reds. It's also encountered in unexpected places like India and China, reflecting the grape's global appeal and adaptability.
Shiraz plays a prominent role in blends as well. In the Rhône, it's often blended with Grenache and Mourvèdre to form the GSM blend, renowned for its balance and the way it combines the best traits of each varietal. In Australia, it's sometimes blended with Cabernet Sauvignon, marrying the former's fruitiness with the latter's structure and tannic backbone.
