Belle de Brillet isn’t exactly new – it’s been around in Europe for over thirty years and the base Brillet Cognac has been around for over three and a half centuries-on to represent the product and has helped re-introduce Belle de Brillet to the United States. Over 20 pounds of Williams pears from Alsace go into each 750ml bottle of Belle de Brillet Poire Williams Au Cognac. These pears are mixed with aged Cognac Brillet along with a “jealously guarded secret ingredient.”
