Chasselas grape variety, also known as Fendant in parts of Switzerland, is a white wine grape that is believed to have originated in the Lake Geneva region of Switzerland. It is a versatile variety, known for its role in producing fresh, light white wines and serving as a table grape. Here are the most comprehensive technical characteristics of the Chasselas grape variety:

Origin

Chasselas is historically associated with Switzerland, particularly the cantons around Lake Geneva. Its cultivation dates back several centuries.

Distribution

While most closely associated with Switzerland, Chasselas is also found in France (notably in the Loire Valley and Savoie), Germany, Portugal, Hungary, Romania, New Zealand, and other wine-producing countries.

Viticultural Characteristics

- **Growth Habit:** Chasselas vines are moderately vigorous, with an early bud burst which makes them susceptible to spring frosts.

- **Yield:** The variety can be quite productive, leading to high yields if not carefully managed.

- **Cluster and Berry Size:** Chasselas produces compact clusters of medium-sized berries. The skin color can vary from green to golden yellow when fully ripe.

### Winemaking Characteristics

- **Aromatics:** Chasselas wines are appreciated for their subtle floral and fruity aromas, often with notes of pear, citrus, and sometimes a mineral component that reflects the terroir of the vineyard.

- **Acidity:** Wines made from Chasselas typically have moderate acidity, contributing to their fresh and light character.

- **Body and Flavor:** These wines are usually light to medium-bodied, with a delicate and refreshing palate that emphasizes its fruitiness and terroir-driven minerality.

### Styles and Blending

- **Wine Styles:** Chasselas is primarily made into dry, still white wines. It is valued for its ability to express the nuances of its growing location, particularly in terms of mineral qualities.

- **Blending:** While most commonly vinified as a varietal wine, Chasselas can occasionally be found in blends, adding its characteristic freshness and aromatic subtlety.

### Regional Expressions
