Schloss Lieser is a 175-year-old Neo-Renaissance castle on the Mosel where Thomas Haag has quietly become one of Germany's greatest Riesling makers. Spontaneous fermentations with natural yeasts, half stainless steel and half traditional barrels, minimal intervention. They farm Grand Cru slopes and make wines that taste like specific places—Lieserer Niederberg Helden, Brauneberger Juffer. This is Mosel Riesling done the difficult, rewarding way.
