What’s the difference between Chablis and Sauvignon Blanc?

Answered by Louis Krause

As an expert sommelier and brewer, I can tell you that Chablis and Sauvignon Blanc are two distinct wines made from different grape varieties. Let's delve into the details to understand their differences.

1. Grape Variety:
– Chablis: Chablis is exclusively made from Chardonnay grapes. Chardonnay is a versatile white grape variety known for its ability to express the terroir and winemaking techniques. Chardonnay grapes grown in the Chablis region of Burgundy, France, produce unique and characteristic wines.
– Sauvignon Blanc: Sauvignon Blanc is made from the Sauvignon Blanc grape. This white grape variety is known for its high acidity and aromatic qualities. It is grown in various regions around the world, including France, New Zealand, California, and South Africa.

2. Growing Region:
– Chablis: Chablis is produced in the northernmost region of Burgundy, France. The cool climate, chalky soils, and unique terroir of Chablis contribute to the distinct characteristics of the wine. The region's proximity to the Yonne River also influences the microclimate.
– Sauvignon Blanc: Sauvignon Blanc is grown in numerous wine regions globally. Some notable regions for Sauvignon Blanc production include the Loire Valley in France (particularly Sancerre and Pouilly-Fumé), Marlborough in New Zealand, and the California Central Coast.

3. Flavor Profile:
– Chablis: Chablis wines are typically dry, crisp, and refreshing. They often exhibit notes of green apple, lemon, and mineral nuances. The cool climate of Chablis contributes to its high acidity, which gives the wines a vibrant and lively character. Chablis is known for its steely and flinty taste, which is a result of the unique Kimmeridgian limestone soil in the region.
– Sauvignon Blanc: Sauvignon Blanc wines are known for their intense aromatics and vibrant acidity. The flavors can vary depending on the region and winemaking techniques. Common descriptors for Sauvignon Blanc include citrus fruits (such as grapefruit and lime), tropical fruits (such as passion fruit and pineapple), and herbaceous notes (like freshly cut grass and bell pepper). Some Sauvignon Blanc wines might also exhibit a hint of minerality.

4. Winemaking Techniques:
– Chablis: In Chablis, winemakers typically use stainless steel tanks for fermentation to preserve the purity and freshness of the Chardonnay grapes. Oak aging is less common in Chablis compared to other Chardonnay-producing regions, resulting in wines with a more focused fruit expression and mineral-driven character.
– Sauvignon Blanc: Winemaking techniques for Sauvignon Blanc can vary. Some producers choose to ferment and age the wine in stainless steel or concrete tanks to maintain its aromatic qualities and crispness. Others may opt for oak aging, which can add complexity and texture to the wine.

Chablis and Sauvignon Blanc are distinct wines made from different grape varieties and grown in different regions. Chablis, made from Chardonnay grapes in the Chablis region of Burgundy, showcases a steely, high-acid profile with mineral nuances. Sauvignon Blanc, grown in various regions worldwide, is characterized by its vibrant acidity, aromatic intensity, and flavors ranging from citrus fruits to tropical notes.
