Chasselas (Fendant)

Chasselas originated on the shores of Lake Geneva in western Switzerland, with its first recorded mention dating to the 16th century. The name Fendant was in use by the 1700s and continued into the early 20th century. Switzerland's wine industry suffered heavily during the phylloxera crisis of the late 1800s, and following a government conservation effort beginning in 1923, the Fendant Roux clone emerged as the dominant strain. Though long assumed to have French roots, modern DNA analysis has confirmed definitively that Chasselas is Swiss in origin.

• First documented in Switzerland in the 16th century
• Fendant name in use since the 1700s; Fendant Roux clone dominant after 1923 conservation efforts
• Heavily impacted by phylloxera in the late 1800s
• DNA analysis confirms Swiss origin, overturning earlier assumptions of French provenance

Chasselas is planted across Switzerland's key wine regions, with the greatest concentration in Valais, Vaud, Geneva, and the Trois-Lacs area. Switzerland recorded 4,013 hectares under vine in 2009, making it by far the most significant country for this variety. Germany grows a further 1,123 hectares, where it is known as Gutedel, primarily in Baden. The grape also grows in France, Portugal, Hungary, Romania, New Zealand, Croatia, and Chile, though at far smaller scales.

• 4,013 hectares in Switzerland as of 2009; 1,123 hectares in Germany (Gutedel)
• Key Swiss appellations: Valais (Fendant), Vaud (Dorin), Geneva (Perlan), Trois-Lacs
• Fendant appellation in Valais has been protected since 1966
• Also grown in France, Germany, Portugal, Hungary, Romania, New Zealand, Croatia, and Chile

Chasselas thrives on the alpine slopes and lakeside terraces of the Lake Geneva region, benefiting from a cool climate that suits its early-ripening character. Soils vary by site, ranging from chalky to clay-based terroirs, each contributing different expressions of minerality. The variety is thin-skinned, which makes it vulnerable but also produces wines of delicacy and low tannin. Its low acidity is a defining stylistic trait across all regions.

• Early-ripening variety well suited to cool alpine and continental climates
• Soils range from chalky to clay depending on the appellation
• Thin-skinned with low tannin and low natural acidity
• Alpine slopes and Lake Geneva lakeside terraces are the heartland sites

Chasselas produces dry, light-bodied white wines with a gentle fruit profile of apple, pear, and citrus, often lifted by floral notes and a distinctive minerality. The style is aperitif-friendly, and some examples show a slight spritz. The name Fendant itself references the way ripe berries split rather than burst when pressed between the fingers. Most bottles are intended for early drinking within 2-3 years, though top examples from exceptional vintages can develop over 10 or more years.

• Flavor profile: apple, pear, citrus, floral notes, and minerality
• Light-bodied, dry, and sometimes lightly sparkling
• Fendant name derives from berries that split (rather than spurt) when squeezed
• Drink within 2-3 years; top vintages can age 10 or more years

Despite being Switzerland's emblematic white grape, Chasselas remains relatively unknown internationally, partly because over 90% of Swiss bottles carry only the appellation name rather than the grape variety. Growing interest from the United States and Asian markets is beginning to change that picture. The variety carries 326 synonyms and prime names in the Vitis International Variety Catalogue, a reflection of its long history across many wine cultures.

• Over 90% of Swiss Chasselas is labelled by appellation, not grape variety
• Renewed international interest growing in the US and Asian markets
• 326 synonyms and prime names recorded in the Vitis International Variety Catalogue
• Switzerland's second most planted variety overall, behind Pinot Noir
