Cowless Dairy is Here! Single-Celled Yeasts are Doing The Work of 1500-Pound Cows
BERKELEY, Calif. — The first course was a celery root soup lush with whole milk. The last was a spice cake topped with maple cream cheese frosting served with a side of ice cream. And then a latte with its fat cap of glossy foam. In all, a delicious lunch. Maybe a little heavy on the dairy.

Lab-grown meat is on the way. But lab-grown dairy is already here.

Dozens of companies have developed in recent months to create milk proteins made by yeasts or fungi, including Perfect Day, the California-based dairy company that arranged this unusual spread. The companies’ products are currently on store shelves in the form of yogurt, cheese and ice cream, often labeled “animal-free.” The blossoming industry, which calls itself “precision fermentation,” has its own trade organization, and big-name food manufacturers such as Nestlé, Starbucks and General Mills have already signed on as customers.
The expedited progress in this area has renewed hope for a revolution in the dairy industry, and not just because it’s kinder to the cows. Precision dairy doesn’t have cholesterol, lactose, growth hormones or antibiotics (though those with dairy allergies should beware). And cattle, for beef or dairy, is said to be the No. 1 agricultural source of greenhouse gases worldwide. Consumers worried about climate change or animal welfare have been anxious for the U.S. debut of cultivated meat, which is grown in labs from animal cells, but cultivated dairy could have just as much of an impression on the environment — with fewer regulatory hindrances to clear.

Despite widespread acceptance of soy, oat and almond milk, U.S. consumers, even vegan ones, continue to be unimpressed by plant-based cheese options: Mostly made of starch and oil, they often do not have the flavor or texture (no gooey strings, not enough bounce) of real cheese. And cheese is particularly bothersome for the environment, more so than its liquid counterpart: Making one pound of cheese requires 10 pounds (or about five quarts) of cow’s milk. The World Economic Forum and many scientific reports proclaim cheese creates the third-highest emissions in agriculture after beef and lamb.
Lab-Grown Dairy Is the Future of Milk!
California-startup TurtleTree is banking on a future, no longer reliant on pastures filled with dairy cows to enjoy our favorite latte – our future milk comes from a lab…https://t.co/12KAGerger via @thedailybeast#Dairy #Milk #Cows— Free Wooly… (@freewooly) March 8, 2023
OMG! Scientists can now produce milk without cows by using single celled yeast. AND THIS WAPO ARTICLE CLAIMS THAT LAB GROWN MEAT IS REAL AND COMING VERY SOON ❤️???! How single-celled yeasts are doing the work of 1,500-pound cows – The Washington Post https://t.co/yaMjZcyfjz
