Dairy farming faces scrutiny over environmental impact, prompting Boston startup Brown Foods to introduce UnReal Milk, the world’s first lab-grown whole cow’s milk.

Dairy farming is under increasing pressure for its environmental impact, consuming vast resources and emitting methane— a greenhouse gas far more potent than CO₂. As the food industry searches for lower-carbon alternatives, Boston-based startup Brown Foods is preparing to showcase UnReal Milk, the world’s first lab-grown whole cow’s milk— produced without a single cow.
According to its founders, UnReal Milk is produced using mammalian cell culture— replicating the nutrition, taste, and texture of traditional dairy. It can be processed into butter, cheese, and ice cream, offering a lower-carbon, cruelty-free alternative to conventional milk. Brown Foods claims its production method slashes carbon emissions by 82%, water use by 90%, and land use by 95%, without relying on livestock.
