How to Understand St. Emilion wines in 5 minutes

Exploring the Diversity of St. Émilion Wines: Soil, Winemaking, and Vintages

Have you ever wondered how wines from one tiny region can taste so dramatically different? I recently attended a St. Émilion wine event in Dallas, (one of several cities in the United States). As guests of Misa Imports, we tasted over 75 wines from this renowned Bordeaux appellation with centuries-old wine history. With château all achieving classification of Grand Cru by the Association de Grands Crus Classés de Saint-Emilion, the event guided some of the region’s best wines. It was an eye-opening experience to see how factors like soil, winemaking, and vintage contribute to the varied expressions of St. Émilion wines.

Understanding St. Émilion: Bordeaux’s Right Bank Gem

St. Émilion wines are some of Bordeaux, France’s most celebrated. This wine region is located on the “Right Bank” of the Dordogne River. Wines from the Right Bank are generally Merlot-dominant. This makes them softer and fruitier compared to the more tannic, Cabernet Sauvignon-driven wines of the Left Bank. Bordeaux wines are traditionally blends, primarily featuring Merlot, Cabernet Sauvignon, Cabernet Franc, and, to a lesser extent, Petit Verdot.

Tasting these wines side by side revealed a fascinating range of flavors and textures. Here’s a closer look at how soil, winemaking techniques, and vintage variation shape these wines.

Soil: The Foundation of St. Émilion’s Terroir

St. Émilion’s vineyards span three main topographical areas: the lower foothills near the river, the mid-slope, and the elevated plateau. The mid-slope vineyards are especially prized for their balance of sun exposure and drainage. Additionally, cooling effects from the river, while the plateau is also highly regarded for its quality.

The soils in St. Émilion are varied, with a mix of clay, limestone, gravel, and sand. Clay soils retain water and stay cool, ideal for Merlot and Cabernet Franc, which thrive in cooler soils. Gravel, on the other hand, is well-draining and retains heat, extending the growing season. This heps later-ripening grapes like Cabernet Sauvignon and Petit Verdot to reach full ripeness.

This diversity in soil means that even wines grown by château close together can taste vastly different. Some vineyards feature layers of clay several meters deep above limestone, encouraging vine roots to reach deeper layers. These different soil profiles impart distinct characteristics to the wines. This makes St. Émilion an exciting region for wine lovers to explore.

Winemaking: The Art of Blending and Barrel Aging

Bordeaux winemakers are known for their skill in blending, a tradition that allows them to adapt to the challenges of each vintage. One year may yield a stellar Merlot crop, while another year may require more Cabernet Franc to balance the flavors. I tasted wines that ranged from 100% Merlot to blends with equal portions of Merlot, Cabernet Sauvignon, and Petit Verdot.

St. Émilion winemakers often age their wines in new French oak barrels, often at least 50% new. This imparts distinctive flavors and help soften the wine’s structure over time. The amount of new oak and the length of aging influence a wine’s character. Some wines showcase high acidity and fruit purity, while others reveal complex layers of oak, spice, and tannins. For fans of more vibrant, fresh reds, some second-label wines even bypass new oak entirely. This lets the grape’s natural acidity and flavors shine.

Vintage: Shifts in Expression Through the Years

The event highlighted St. Émilion wines from several vintages, from 2012 to 2022, underscoring how vintage variation impacts flavor. In the past, Bordeaux wines could vary significantly from one year to the next. The effect of global warming is bringing riper, more consistent vintages, sometimes shifting the wines’ profiles from red fruits to richer black fruit flavors. This increased ripeness can also result in slightly higher alcohol levels, giving the wines a fuller body.

Many producers showcased their “second labels,” which are more approachable, early-drinking versions of their flagship wines. These wines offer excellent value and can be enjoyed sooner, while still delivering the terroir-driven complexity of St. Émilion.

Conclusion: A New Appreciation for St. Émilion Wines Diversity

Attending a comparative tasting of St. Émilion Grand Cru Classé wines was a powerful reminder that wines from the same region can be anything but homogenous. From the varied soils to the unique winemaking choices and evolving climate influences, St. Émilion, itself a world heritage site,  is a region of captivating diversity. So next time you enjoy a bottle from this appellation, remember that you’re tasting a piece of Bordeaux’s dynamic landscape, shaped by the land, the craft, and the ever-changing weather patterns.

    Great article! I too had the pleasure of attending this event and I would add the representatives from the various chateaux were very engaging and they encouraged all of us to pay a visit to historic St. Emilion in the near future. These are truly remarkable wines.
