Isigny Sainte-Mère: The #1 French Butter

You’re here because not all French butter is created equal. If you’re searching for the best butter to transform simple food into an extraordinary meal, Isigny Sainte-Mère—often written Isigny Ste Mère—is the gold standard. This is authentic beurre d’Isigny from Normandy, France, protected by the prestigious AOP/PDO (Protected Designation of Origin)—formerly AOC—which guarantees origin, method, and terroir.

Discover Isigny Sainte-Mère

Imagine isigny butter so deeply flavorful and so exquisitely creamy that it elevates everything it touches. Thanks to the unique terroir around Isigny-sur-Mer and time-honored dairy know-how, it delivers a silky, creamy texture with elegant, natural hazelnut notes. Chefs prize it for laminated pastry, sauces, and finishing.

A Legacy of Excellence in Normandy, France

Founded as a farmer-owned cooperative in 1932, Isigny unites families who’ve worked the same coastal meadows for generations. Cows graze mineral-rich, grass-fed pastures near the Channel; the salty breezes and iodine-rich soils shape the milk—and thus the butter’s flavor. That sense of place—terroir—is why the AOP/PDO exists.

What Sets Beurre d’Isigny Apart

Slow Maturation, Cultured Character

Isigny matures cream for 16–18 hours with carefully selected lactic starters, then makes churned butter the traditional way. This slow, cultured butter process builds complexity you’ll taste in both salted butter and unsalted butter styles.

Texture & Flavor

Expect a naturally golden color (from beta-carotene in cow’s milk), a supple, elastic crumb for pastry work, and a long finish with toasted dairy and hazelnut hints. It melts evenly and enriches sauces more gently than oils (save your olive oil for sautéing—reach for Isigny to mount sauces or finish grilled fish).

Clean & High-Quality

Isigny’s farming standards emphasize animal welfare and non-GM feed (GMO-free finished butter), with rigorous traceability and food safety. If you care about high-quality inputs, this is your benchmark.

• Isigny Sainte-Mère Unsalted Butter (Doux)
