I'm guessing even Siggi's is made from A1 milk? Unless it's Jersey milk not the more common Holstein? Not actually planning to buy it presently, since I suspect I may be sensitive to A1 casein. Other common brands of whole milk yogurt didn't seem to work for me and I suspect that might be why. The raw milk dairy closest by genetically tested all their cows and posted a discreet list for those interested in knowing. Discreet meaning it's not obvious what the list refers to unless you ask the farmer. He has some non-A2 Jerseys that are good milkers he'd like to sell from for those who don't have a preference. I've made fermented milk products from his A2 milk, since I haven't seen any at the stores.
