Which French cheese was called the “king of the cheeses"?
In the 19th century, Brie de Meaux, a soft, white cheese named after the town of Meaux in the French region of Brie, was nicknamed "le roi des fromages," or the “king of cheeses,” by the Prince of Talleyrand, a French statesman and diplomat. In a moment of French pride at the 1814 Congress of Vienna, Talleyrand declared Brie “the king of cheeses and cheese of kings,” as the creamy snack was known to have been enjoyed by such famed rulers as Charlemagne and Louis the XVI.
