The winery is just up from the river on a straight east-west stretch of the Mosel. It sits in the shadow of the recently renovated and opulent hotel, Schloss Lieser. Thomas and Ute Haag purchased the winery in 1997 after Thomas had already been making wine at the estate for five years. Thomas comes from a winemaking family, his younger brother Oliver runs the historic Fritz Haag estate that was established in 1605. Thomas and Ute farm 22 hectares with excellent parcels in several villages along the Mosel. Their children Lara and Nikolas are both working in the family business.

The Schloss Lieser style is precise, focused, and pure. The wines hinge on taut acid and an almost pithy texture. The quality is top tier for every sweetness level. The Prädikatswein and Grosses Gewächs wines require age to show their true brilliance, but the Gutswein and Ortswein bottlings offer excellent early-drinking appeal. Top sites include Piesporter Goldtröpchen, Bernkasteler Doctor, Wehlener Sonnenuhr, Graacher Himmelreich, Lieser Niederberg Helden, Brauneberger Juffer, and Brauneberger Juffer Sonnenuhr. VDP estate.
