Terroir: What Does It Mean & What Are Terroir Wines?

Curious what really shapes the flavor of your favorite wine? The term "terroir" describes how nature and tradition come together to form a wine's character. Factors like climate, soil, and time-tested growing methods all combine to give every wine its distinct personality. Learn how these elements interact and why they're essential to your wine's unique flavor and style.

What Does Terroir Mean?

Along with many beautiful French wine-world words, the term "terroir" often comes up. "Terroir" comes from the Latin "terra," meaning earth.

Terroir definition: Terroir refers to everything shaped by nature in a particular place that influences the flavor of the wine. Winemaking traditions can also become woven into this complex concept over time. The end result is a distinctive wine style that isn't easy to pin down and even carries a bit of mystique.

In classic, originally French wine classification, terroir plays a bigger role than the grape variety or vintage. Take, for example, Pinot Gris from the Kaiserstuhl region in Baden and Pinot Grigio from Friuli in Italy. The same grape variety produces completely different wines, even to an untrained palate.

What Factors Make Up Terroir?

The factors that most strongly influence terroir include:

• The climate in a specific wine-growing region: especially temperature and temperature fluctuations, rainy and sunny days, wind, and the risk of smaller or larger deviations or disasters
• The microclimate of a specific vineyard site: for example, despite the generally unfavorable climate for winemaking in Brandenburg, the town of Werder an der Havel has a microclimatically favorable vineyard site recognized for centuries
• The landscape's topography: elevation, proximity to water, slope, and incline
• Soil: mineral content, moisture, and other properties
• The natural surroundings: forests, meadows, fields with specific plants and animals, the sea, or other bodies of water
• The rootstock: ungrafted vines growing on their own roots, or grafted onto rootstock from a different origin
• Winemaking traditions: vine training methods, fertilizers used, typical harvest timing, and more

How Does Soil Influence Wine?

When you talk to winemakers, they'll likely bring up the role of soil in shaping their wine's style right away. It often seems so important that we see it printed directly on wine labels: "Riesling from blue slate," "Merlot from loess," "Muschelkalk Grüner Veltliner," or simply "Urgestein" (primary rock) or "Terra Rossa."

Here's how soil influences wine:

• Alkaline soils (limestone, especially chalk) produce grapes with high acidity.
• Acidic soils (flint, granite, quartz, sand) produce grapes with lower acidity.

More key details on how soil shapes wine:

• Flint (e.g. Châteauneuf-du-Pape in France), limestone with fossilized shells (e.g. Silvaner from Franconia), and granite (e.g. wines from Beaujolais in France, Wachau in Austria, or Rías Baixas in Spain) give wines a distinctive minerality and crisp character.
• Slate: often produces lighter, higher-quality wines, such as some Rieslings.
• Sand (common in many coastal wines): produces intense aromatics.
• Loess (found in many German wines): supports longer aging potential.
• "Flint" or "gunflint" ("Feuerstein"), a term increasingly seen on labels, doesn't refer to a specific soil type at all, but rather a positive flavor description for a wine that's very dry, clear, mineral-driven, and slightly smoky. Examples: Chablis, Sancerre, Pouilly-Fumé, Vernaccia di San Gimignano.
• "Urgestein" describes a varied, less specifically defined soil composition.

What Types of Terroir Wines Exist?

The best-known terroir region is arguably Champagne, whose vineyards and cultural landscape have even been added to the UNESCO World Heritage list.

Many sparkling wines around the world are made using the traditional Champagne method, but that's far from the whole story. It's no coincidence that winemakers from this region, just a two-hour drive from Paris, fought to ensure that only their wines could be called Champagne.

Soil plays a major role in shaping the unmistakable character of the world's most famous sparkling wine. The soils of Champagne are extremely chalky, and have been for millions of years. That gives the wine its signature acidity and freshness, both essential for sparkling wines. And subtle differences in soil composition across Champagne's various sub-regions create the wide variety of exceptional wines found there.

The region's harsh climate, paired with just the right amount of sunshine and rainfall, creates near-ideal growing conditions for Chardonnay, Pinot Noir, and increasingly Pinot Meunier grapes used in Champagne production. Still wines, on the other hand, would often turn out too acidic and flavorless in this region.

Can You Actually Taste Terroir in Wine?

Tasting terroir in wine might be easier than you think. Organize a small wine tasting with friends, featuring three Rieslings: one from the Mosel, one from the Rheingau, and another Riesling from a different wine country, such as France (Alsace), Italy, Austria, or New Zealand.

All three wines should be dry and roughly the same alcohol content and price. During the tasting, you'll notice clear stylistic differences (not just flavor differences). A lean, delicate Mosel wine with a hint of honey in its aroma, a lively, full-bodied Rheingau Riesling, and perhaps some exotic or at least unfamiliar notes in the third wine. And the next time you try other Rieslings, you'll start to notice even more clearly what makes a wine from a particular region distinct and recognizable.

Of course, you can try the same kind of tasting with Chardonnay, Pinot Gris, Pinot Noir, or Syrah. Sometimes you'll be able to clearly identify and describe the regional differences. But other times, a touch of magic remains in their terroir that's hard to put into words.
