Deutz is a Champagne estate in the Ay region of Champagne. The estate was founded in 1838 and was originally known as Deutz Geldermann, since it was owned and run for many generations by the Deutz and Geldermann families. In 1993 it was acquired by Louis Roederer. In the 1980s and 1990s Deutz partnered with wine producers in New Zealand and California to produce sparkling wines. In Champagne the estate owns 105 acres of vineyards and it also sources grapes from nearly 400 acres of vineyards in Champagne. The estate style is based on Pinot Noir, which makes up 55% of the flagship cuvee William Deutz.
