All natural. Our Farmer's Pledge: No artificial growth hormones. (The FDA has said no significant difference has been shown and no test can now distinguish milk from rBGH treated and untreated cows.) Vanilla on the bottom. 1% Milkfat. Grade A. Brown Cow isn't like any other yogurt. It all started with a family farm and a lovely brown cow named Lily. Our creamy low fat yogurt is still made in small batches using only the finest natural ingredients for a fresh-from-the-farm taste. It's so rich and delicious, you'd never know it's 99% fat free!
