From the PastureLand website:
PastureLand 100% grass-fed organic dairy products are handcrafted by artisan butter and cheese makers with the milk of cows that spend their days grazing the pastures on our farms in Southeast Minnesota.
Our organic Summer Gold™ cultured butter and artisan cheeses are known for their exquisite taste and quality, and get their outstanding flavor and grass-fed nutrition from the lush pasture grasses that the cows graze from April through November.
