All Kerrygold butter comes from the milk of grass-fed cows that are free of growth hormones. Our Unsalted Butter is creamy Irish butter with a nuanced cultured flavor profile. Kerrygold Unsalted Butter has a higher butterfat content and is a perfect butter for baking. You’ll notice its grass-fed cow’s milk richness when you bake for the first time and find your pie crusts are flakier and your cookies are more delectable thanks to Pure Irish Butter.
