So why would Jay-Z get involved with a second-tier champagne? Because of the immense profit potential. Fass estimates that Cattier’s production cost for each $300 bottle of Armand de Brignac is a mere 10 euros. Assuming Jay-Z is an investor, the connection could be through any number of outlets: Cattier itself, the brand Armand de Brignac, the importer, the exporter, or the distributor. All of these entities are registered with an array of state and national government agencies in the United States and France. Theoretically, the link could be established with a little bit of sleuth work.
