Egon Muller IV is heir to one of Europe's great winemaking dynasties. His father added to the family's portfolio of distinguished old vines by acquiring six acres of the eminent Weingut Le Gallais in Wiltingen. Fruit sourced from the Kupp and Braune Kupp blocks of La Gallais make the most compelling Riesling wines, to rival the profound efforts of the great Scharzhofberger vineyard.

The highly elevated Le Gallais property at Wiltingen is notable for being one of the few Mosel vineyards that looks down onto the Saar rather than into one of her tributaries. The sheltered bend, between Kanzem and Wiltingen, is considered the best microclimate in the district. Weingut Egon Muller acquired half of the eminent estate in 1954, leasing the balance of the property from Madame Rochon. Braune Kupp is fermented mostly through the action of wild yeasts in old, thousand litres oak foudres. The wines are raised in ancient cellars which were built by mediaeval monks. The deep, very cold and damp environments make the perfect environment in which to gently age the wines, built for the long haul.
