Which grape varieties create the magic of Bordeaux wine? 🍇 Bordeaux is a bit like a large family of grape varieties, each bringing its own character. In red, the star is, of course, Cabernet Sauvignon. This grape variety, often described as noble, produces rich, full-bodied wines with aging potential and aromas ranging from blackcurrant to oaky notes. But it doesn’t stand alone.
Merlot
comes in to soften the game: it brings a touch of sweetness and easy-to-appreciate fruity flavors, making it a perfect balance for blends. Cabernet Francplays the role of spice with its more intense, slightly peppery notes. Alongside this, Petit Verdot adds depth, a sort of extra layer to the wine’s structure, while Malbec , although less common, elegantly shapes the length on the palate. Don’t miss the white grape varieties either, which bring another facet of the Bordeaux vineyard to life. Sauvignon Blanc offers that refreshing, sparkling, and aromatic acidity. Semillon, rounder and creamier, is the star of sweet wines, particularly Sauternes. As for Muscadelle, it brings a delicately floral and spicy bouquet, perfect for adding a twist to blends.

| Nothing is left to chance as the harvest approaches, a crucial stage in the Bordeaux winegrowers’ calendar.

Harvesting is not done lightly, as each bunch will influence the final quality. | Harvesting can be carried out manually or by machine, depending on the estate. The most prestigious, such as Château Mouton Rothschild or Château Cheval Blanc, often opt for hand-picking to carefully select the finest grapes.

|---|---|---|
| Once the must is ready, the magic of fermentation begins. The sugars in the grapes slowly transform into alcohol thanks to the action of yeast. On the left bank of the river, where Cabernet Sauvignon-based wines dominate, fermentation often takes place at relatively high temperatures to extract tannins and intense colors. | For white wines, fermentation is gentler, controlled at low temperatures to preserve freshness and aromas. Dry white Bordeaux wines, such as those from the AOP Vin Sud-Ouest (Southwest Wines), draw on this mastery to stand out for their elegance. Next comes aging, a key step that can last from a few months to several years. This is where red wines like those from the prestigious Château Latour or Château Palmer refine their woody notes in oak barrels, gaining complexity and finesse. Aging also contributes to the integration of tannins and the wine’s stability—a true watchmaking process. To summarize: | 🎛️ |
