Fleur de Passion is the jewel in the range from the house of Diebolt-Vallois. Fermented and aged in barrels, it is only made in the very best years. Alcoholic fermentation take place in barrels. Malolactic fermentation, filtration and fining are all avoided. Anything which might stress the wine is proscribed, so that the terroir can express itself as fully as possible. The wine is aged in burgundy 1-wine barrels, this is a “old style”, traditional champagne .
