Champagne house as famous for its eponymous founder, the first great champagne widow (veuve in French), as for its wines. Nicole Barbe Ponsardin (1777–1866) married François Clicquot, an owner of Champagne vineyards, in 1798. The wedding took place in a Champagne cellar as churches were not yet reconsecrated following the French Revolution. François Clicquot died in 1805, leaving Mme Clicquot in charge of the company, which she renamed Veuve Clicquot Ponsardin. The widow steered the house carefully through the turbulent years of the First and Second Empires, defying Napoleon's blockades to ship the wine to Russia, and finding an export market in virtually every European court. 'La Grande Dame' is credited with inventing the riddling process called remuage, and adapting a piece of her own furniture into the first riddling table for that purpose. She devised the famous yellow label, still used for the non-vintage wine. On her death, the company passed to her former chief partner, another shrewd businessman, Édouard Werlé, and the house remained in the hands of the Werlé family until in 1987 it became part of the Moët Hennessy-Louis Vuitton group. The house style is based on Pinot Noir grapes and, in particular, those grown at Bouzy, where the house has large holdings. La Grande Dame is Clicquot's prestige cuvée, named, of course, after the widow. In 1990, the Champagne house purchased a majority stake in the western australian winery Cape Mentelle and its New Zealand subsidiary cloudy bay, completing the purchase in 2000.
