Moet Hennessy USA (MHUSA) had some harsh words to say about champagne rival Armand De Brignac in a lawsuit filed in New York Federal court on Friday. MHUSA claims Delaware-based defendants Ace of Spades holdings, Armand De Brignac Holdings and Sovereign Brands are attempting to "deceive and mislead" consumers into believing that the entire line of Armand de Brignac cuvees are currently rated "The No. 1 champagne in the world."
