The famous Saar estate has been in the hands of the Muller family since 1797 and they currently own just over 8 hectares of the stellar Scharzhofberg vinyeard, the Saar's most qualified contender for the title of "great growth", challenging the famous sites of the Middle Mosel with ease. Egon Muller's single vineyard holding is dominated by Riesling through a small patch is planted to other varieties and he consistently produces wines of incredible purity, line and detail from the slate soils of the famous vineyard.

Egon Muller is the sole German member of the Primum Familiae Vini whose other members include Chateau Mouton Rothschild, Vega Sicilia, Torres, Pol Roger, Antinori and Hugel et Fils.
