Organic. The Herrenletten Erste Lage sits adjacent to Bürgergarten. The name Herrenletten combines both the historical and the geological: Herren, indicates that the region was owned by noble landlords in the Middle Ages; the second part, letten, refers to the type of soil—sandy clay with layers of limestone and chalky clay. The oldest Riesling vines here are 40 years old (the site is also home to Pinot Blanc and Pinot Gris).
