Exploring Terroir: The Influence of Geography on Wine
Terroir: a French term that encapsulates the essence of a place.
Terroir plays a pivotal role in shaping the character and quality of wine. It’s the intricate interplay between geography,
geology and climate that gives each wine its distinct personality. Let’s delve into the fascinating world of terroir and understand how it affects the wines we savour.
CLIMATES
Wine regions can be broadly categorised into two climates: cool and warm. The climate influences the ripeness of grapes, which in turn affects the sweetness, acidity, and alcohol content of the wine.
WARM CLIMATES
Grapes from warmer regions yield higher sugar levels, resulting in wines with elevated alcohol content. Warm climate reds often have ripe fruit flavors, such as Shiraz, and Cabernet Sauvignon.
Reds tend to be fruit-forward with a higher alcohol content, like Chardonnays.
COOL CLIMATES
Result in wines with higher acidity and more tart fruit flavours. Typically, reds exhibit, spicier notes, lower alcohol, and a lighter body, such as Pinot Noir, and Merlot. Cool climate whites are known for lemon-lime aromas, and generally lower alcohol, including varieties like Sauvignon Blanc .
SOIL – THE EARTH’S FLAVOUR PALETTE
Vineyards worldwide boast a rich diversity of soil types, each influencing wine flavour. While the link between minerals and wine taste isn’t scientifically proven, something magical happens.
Wine regions can be broadly categorised into two climates: cool and warm.
COOL CLIMATE WINES
SAUVIGNON BLANC: Known for its crisp acidity and green herbal flavours.
PINOT GRIGIO: Often lighter-bodied with high acidity and citrus notes.
ROSE: Can be made in both climates but those from cool climates tend to be lighter and crisper.
WARM CLIMATE WINES
MOSCATO: A sweet, lightly effervescent wine often from warmer regions.
PINK MOSCATO: Similar to Moscato but with a hint of berry flavours.
CHARDONNAY: In warm climates, it tends to be fuller-bodied with tropical fruit flavours.
SHIRAZ: Known for its bold flavours and spice, thrives in warm climates.
MERLOT: Typically, lush and fruit-forward when grown in warmer areas.
SYRAH DOLCETTO: Syrah adapts well to heat, producing robust wines; Dolcetto is less common in warm climates but can produce soft and fruity wines.
CABERNET SHIRAZ: Both varietals favour warmth, leading to rich and intense wines.
CABERNET SAUVIGNON: Favours a warmer climate to fully ripen its tannins.
BOTH CLIMATES
SEMILLON SAUVIGNON BLANC: Semillon can adapt to both warm and cool climates, often blended with Sauvignon Blanc to balance its acidity.
TRADITION: THE CULTURAL THREAD
In areas steeped in winemaking tradition, techniques contribute to terroir. Whether it’s time-honored practices or regional customs, they shape a wine’s identity.
TERRAIN: ALTITUDE AND BEYOND
Altitude is gaining prominence in quality vineyards. Other factors include:
GEOLOGICAL FEATURES: Mountains, valleys, and inland locations impact wine taste.
FLORA AND WATER: Nearby plants, microbes, trees, and large bodies of water all leave their mark on a wine’s character.
Remember, terroir isn’t just about the soil – it’s the symphony of sun, earth, and climate that harmonises in every bottle. So, raise your glass to the land, the vines, and the stories they tell!

The terroir of the Riverina region impacts the wine produced, in several key ways.
CLIMATE: The Riverina has a Mediterranean-like climate with hot summers and cool winters, which is ideal for producing rich, full-bodied wines.
SOIL: The main soil type is red-brown earth, consisting of highly variable alluvial soils with sands and gravels embedded in clays. Many of these soils also contain limestone rubble, which can contribute to the mineral qualities of the wine.
RAINFALL: The region receives a significant amount of rain, but it also has a dry winter season with little humidity. This combination allows for controlled stress on the vines, which can concentrate the flavors in the grapes.
ALTITUDE: While the Riverina is largely flat, the altitude ranges from 66 to 540 meters, which can influence the microclimates within the region.
These elements of terroir contribute to the distinctive characteristics of the wines from the Riverina, ranging from robust reds to luscious, sweet whites. The region’s ability to produce a diverse range of wine styles is a testament to the complex interplay of these terroir factors.
