Hagnauer – grown in exceptional vineyards at Lake Constance

On sunny days, the glitter on Lake Constance shows the lake’s advantages for wine growing: the light is reflected on the water and the vines in the Hagnau vineyards benefit from the warmth of the reflection.

Lake Wine

The water masses of the largest German lake store the heat during summer. In autumn, the nights become cooler and the lake then releases the heat gained over the summer to the vines and ensures slow ripening of the grapes. Temperature fluctuations between day and night and between summer and winter are compensated.

The Lake is essential for the vines – it prevents late frosts in spring and ensures wine growing in Germany’s most southern and highest wine growing region at over 400m above sea level. Wines that are appreciated from wine connoisseurs beyond the borders.


The ice age glaciers left the lake and glacial weathered soils on its banks and in the vineyards. The soil conditions are very different. Loam soils interspersed with sandy loam alternating with bog, marl and clay soils.

The soil gives the lake wine delicate elegance and fruitiness. The location over 400m above sea level ensures freshness and lightness – just like the landscape, the people and the lake.
