Jean-Jacques Koch, Egon Müller's great great-grandfather acquired the Scharzhof estate from the "République Française" in 1797 after the French Revolution and the occupation of the West Bank of the Rhine River by the revolutionary government. The Scharzhofberg vineyard was likely planted by the Romans and belonged to the Monastery "St Marien ad Martyres" in Trier from its founding around 700 A. D. through the Middle Ages.

Egon Müller's vineyards are exposed to a northerly climate. Consequently, much depends on the vintage and on late harvesting. Regarding the winemaking process, however, Egon Müller's family's philosophy is based on the belief that the best wines are the ones that "make themselves". The Egon Müller-Scharzhof family lives in its own vineyards and oversees the day-to-day operation at the estate.

All of the family's wines are Rieslings. "Scharzhof" is their most basic wine. Qualitätswein by German legal standard, it is made of the grapes from their vineyards in Saarburg, Kanzem and Wawern and from the Wiltinger Braunfels and Wiltinger Kupp vineyards. The Kabinett wines, made from ripe grapes with low alcoholic content constitute the backbone of the production.
