The fame of Isigny Beurre de Baratte butter goes back to the 16th century. Years later, in the 19th century, the population of Paris alone consumed 800 tonnes of butter a year. How do they explain the fact that the gourmets of the day favored Isigny butter? It is simple! The Isigny terroir has the advantage of a mild, damp climate; is near the sea; and enjoys the benefits of the Bessin and Cotentin marshes. The cows which graze there are fed on grass rich in iodine, beta carotene and trace elements.
