The answer is ‘Yes.’ Not all breeds of cows produce the same kind of milk. Bellwether Farms uses milk from Jersey cows that we source from neighboring farms here in Sonoma County, California. The California Dairy Research Foundation has documented that Jersey cow milk contains A2 beta-casein protein, not the A1 protein that many find difficult to digest. There are additional studies with small groups of human subjects who self-report intolerance. In these studies, people reported no issues with milk that contained only A2 protein.
In addition to being more digestible, Jersey cow milk also has a richer, more full taste and texture.
