I also use the organic milk to make my own yogurt using a small inexpensive yogurt maker. After finding that Stonyfield is my favorite brand, I simply use that as a starter to make my own which is less expensive and tastes just as good since I am starting from organic milk. I buy a quart of Stonyfield yogurt a couple of times a year to restart the process.
The O organics brand at the Shaws supermarkets here in Maine is affordable, and I am pleased that this company supports organic products and local farmers.
