Overview of Bordeaux grape varieties

The Bordeaux vineyard, recognised worldwide for the quality of its wines, owes its uniqueness to a specific combination of terroirs and grape varieties. The identity of Bordeaux wines is shaped by this varietal diversity, even though certain grape varieties dominate today. Historically, Bordeaux was home to a multitude of grape varieties, many of which have been forgotten or marginalised over time. Today, we mainly distinguish between red grape varieties and white grape varieties, each bringing its typical characteristics to the blends.

A historical context of constant evolution

The Bordeaux varietal mix has constantly evolved over the centuries, adapting to climatic and economic constraints, as well as technical advances. Before phylloxera at the end of the 19^th century, the diversity was much greater. The phylloxera disaster, followed by the reconstruction of the vineyard, favoured rationalisation and a shift towards more productive and resistant grape varieties. The establishment of Appellations d'Origine Contrôlée (AOC) from 1935 (Source 3) subsequently formalised and sometimes restricted the list of authorised grape varieties, thereby standardising the plantings, particularly for red wines.

The history of Bordeaux grape varieties is full of twists and turns. Certain grape varieties, once ubiquitous, have disappeared or become very rare, while others, more resistant or better suited to market changes, have taken over. The encounters of modest grape varieties is a subject intrinsically linked to the winegrowers' desire to produce quality wines, capable of adapting to consumer tastes and the demands of successive markets (Source 2).

Ampelographic and oenological trends

Bordeaux grape varieties, whether red or white, exhibit diverse ampelographic and oenological characteristics that allow winegrowers to create a broad palette of wines. For the reds, the complementarity between Cabernet Sauvignon, Merlot and Cabernet Franc is undeniable, offering structure, fruitiness and freshness. As for the whites, Sémillon, Sauvignon and the Muscadelle grape variety stand out for their ability to produce aromatic dry wines and opulent sweet wines. What these grape varieties share is an aptitude for blending, making it possible to achieve a balance and complexity that single-varietal wines more rarely offer.

Current challenges: climate, biodiversity and renewal

Faced with current challenges, notably climate change and the preservation of biodiversity, the Bordeaux vineyard is in a period of deep reflection. The quest for freshness, lower alcohol content and acidity in wines encourages the experimentation with new grape varieties or the return of ancient grape varieties, better suited to future conditions. 'Resistant' or 'adaptive' grape varieties are also being studied to sustain viticultural activity. This approach is part of a desire to diversify the offering and guarantee the vineyard's resilience in the face of climatic uncertainty.

Château Cazebonne's work on Bordeaux grape varieties

At Château Cazebonne, we are deeply committed to promoting Bordeaux's viticultural heritage. Beyond the iconic grape varieties, we take a keen interest in the Bordeaux grape varieties of yesteryear, those that marked the history of the vineyard before being forgotten. Our commitment is reflected in the replanting of these rare grape varieties, such as Blanc Verdet or Castets, in order to enrich the complexity and typicality of our wines. This proactive approach aims to bring forgotten flavours back to life and explore new expressions of our terroir.
