The Three Lakes region (German: Drei-Seen-Land) is located in western Switzerland around Lake Biel (Bienne), Lake Neuchâtel, and Lake Murten. The vineyards extend along the shores and gentle slopes surrounding these lakes, benefiting from reflected sunlight and temperature moderation provided by the water.
The climate is relatively mild compared to other Swiss regions, with good sunshine and cooling lake breezes that help maintain acidity. Soils vary from limestone to clay and gravel, contributing to diverse wine styles across the cantons of Neuchâtel, Vaud, and Bern.
The region is particularly known for Chasselas, which produces fresh, mineral-driven white wines. Pinot Noir is also widely planted and is the base for both red wines and the traditional Neuchâtel rosé known as Œil-de-Perdrix. Other varieties include Chardonnay and Gamay in smaller quantities.
Wines are classified under the respective cantonal AOC systems, including AOC Neuchâtel, AOC Vaud, and AOC Bielersee (Lake Biel), reflecting Switzerland's decentralized wine structure. Production is moderate in scale and largely consumed domestically.
