Beurre Fermier is “Farm Fresh Butter”, or more literally, “farm butter.”
It is made and sold in France and Québec, Canada, by small producers right on their farms. It’s often made by hand without the use of electrical machines, just as it would have been made a long time ago.
As Beurre Fermier is made from unpasteurized milk, it doesn’t keep long: up to a maximum of 8 days, even refrigerated. But, it offers a variety of tastes, depending on what the farmers fed their cows, because it is not blended in large batches to standardize the taste, as creamery butter is.
