Brie cheese round with slice cut out
The French Brand Responsible For Costco's Kirkland Brie
By Stacie Adams
Costco's Kirkland brie is beloved for its silky-smooth texture, rich, buttery flavor, and mildly earthy scent. The brand behind the cheese is the French company Isigny Ste. Mère.
Isigny Ste. Mère began in 1909 as a cooperative formed to improve milk production among local farmers hoping to sell their products in Paris.
Today the company produces the renowned brie along with Camembert, smokey Pont-l'Évêque, Normandy Tomme, Pavé d'Isigny, and Mimolette, known for its orange rind.
Since the brie comes from France, it can be overpowering to some customers, so for those who want a mild cheese, Costco recommends enjoying it a month before its sell-by date.
For those who enjoy a stronger cheese, it's best to eat it around the sell-by date, and if you want a cheese in the middle, use the brie around two weeks prior to the sell-by date.
