The deal is Louis Roeder's first acquisition in the Napa Valley. In February 2019, Maison Louis Roederer purchased Merry Edwards in Sebastopol in Sonoma County. "The acquisition of Diamond Creek is the continuation of our journey into the greatest appellations in the world and our relentless quest to produce great wines with strong identity. Reflective of their pioneering characters, Al and Boots Brounstein built Diamond Creek from the ground up, producing some of the most celebrated and singular wines of the region," Frédéric Rouzaud, President and CEO of Maison Louis Roederer, said. "I am delighted that, once again, we have the opportunity to carry on the opus of an iconic family and embody its values and savoir-faire."
