Climate, terroir, winemaking techniques and more...

That’s a question I get asked quite often. Though not specifically about chardonnay but rather why do wines from different regions taste so different even though they are made from the same grape?

The taste difference between Chardonnay from France and Chardonnay from California can be attributed to several factors, including climate, terroir, winemaking techniques, and stylistic preferences. Here are some key reasons for the taste disparities:

  1. Climate: France and California have different climates that greatly influence grape ripening and flavour development. In France, particularly in regions like Burgundy and Champagne where Chardonnay is prominent, the climate tends to be cooler. This cooler climate allows the grapes to retain higher acidity and develop more subtle, nuanced flavours. In California, on the other hand, the climate is generally warmer, resulting in riper grapes with more pronounced fruit flavours.

  2. Terroir: Terroir refers to the combination of soil, climate, and other environmental factors that influence grape growth and flavour characteristics. French Chardonnays are often influenced by specific terroirs, such as the limestone and clay soils in Burgundy or the chalky soils in Champagne, which impart their unique qualities to the wines. California has diverse terroirs, including regions like Napa Valley and Sonoma, which can produce Chardonnays with different flavour profiles depending on the soil types and microclimates.

  3. Winemaking Techniques: Winemaking practices can vary between France and California, leading to differences in the style and taste of Chardonnay. French winemakers often emphasise minimal intervention and allow the grapes and terroir to shine through. This can result in more restrained, elegant Chardonnays with less emphasis on oak flavours. In California, winemakers tend to employ more modern techniques and often use oak barrels for fermentation and ageing. This can contribute to a richer, fuller-bodied Chardonnay with more pronounced oak and vanilla notes.

  4. Stylistic Preferences: There are also differences in stylistic preferences and traditions between French and Californian winemakers. In France, the focus is often on expressing the unique characteristics of the terroir and achieving balance and finesse in the wines. In California, winemakers may aim for riper, fruit-forward styles with greater emphasis on intensity and richness.

It’s important to note that these are generalisations, and there can be variations within both regions. Winemaking techniques, vineyard management practices, and individual winemaker choices can greatly impact the final taste of Chardonnay from any given region. Additionally, there can be a wide range of styles within each region, offering diverse expressions of Chardonnay.

If you’re a true Chardonnay fan, your best bet is to taste quite a few different Chardonnays from different regions and build your own picture of the various taste and profile spectrums.
