Champagne Barons de Rothschild is a joint project of the three branches of the Rothschild family. The partners are Philippe Sereys de Rothschild (Château Mouton Rothschild), Benjamin and Ariane de Rothschild (Château Clarke, Groupe Edmond de Rothschild) and Eric and Saskia de Rothschild (Château Lafite Rothschild). The founding is usually dated to 2005, though some sources give 2003 as the start. In 2007 the house moved into its headquarters in Reims, at the corner of Boulevard Lundy and Rue Camille Lenoir. It also took over the Maison Prieur in Vertus as a production site. The name is not entirely new to champagne: the family had held a stake in Ruinart from 1945 and later in Champagne Henriot.
The style is built on Chardonnay. Instead of the Montagne de Reims, the Rothschilds chose the Chardonnay country around Avize, Le Mesnil-sur-Oger, Oger and Cramant. The champagnes age for at least four years in the cellar, with a minimal dosage. Even the rosé is a Chardonnay-led wine: 94 per cent Chardonnay and 6 per cent Pinot Noir. The chef de cave since 2016 is Guillaume Lété, one of the youngest in the region.
The range includes Concordia Brut, Blanc de Blancs, Rosé, Millésime and Brut Nature, as well as the prestige cuvées Rare Collection and Rare Collection Rosé. The Blanc de Blancs is regarded as the house's signature cuvée. The Rare Collection Blanc de Blancs comes 100 per cent from four grands crus of the Côte des Blancs: Avize, Cramant, Oger and Le Mesnil-sur-Oger. Le Grand Clos is the house's first single-vineyard cuvée, made from a historic clos in Champagne.
