Among connoisseurs, this is a very beloved butter. Beurre d'Isigny de Baratte is lightly salted. The cream is churned until the butterfat settles along the edge. Salt is added to make the butter last longer. The lightly salted cream butter is fine, contains predominantly saturated fatty acids, and is rich in calories. The cream used in this butter comes exclusively from cows in the French region of Isigny. Beurre d'Isigny has an AOC label: Appellation d'Origine Contrôlée. This is a French quality label for agricultural products.
