Janet, this is good timing! I started making kefir on a regular basis a few weeks ago, and I was looking for some healthy whole milk and learned that A2/A2 (tested cow/bull parents) was the way to go. Short of getting cattle shares with a local farm with an A2 herd in VA, because VA does not allow the sale of raw milk unless one owns the cow, I had to search for something healthy in a local store. At Whole Foods, I found Snowville Creamery from Ohio is certified A2/A2. Their whole milk is pasteurized (not ultra-pasteurized) and non-homogenized. Because the kefir bacteria and yeast consume most of the lactose, the kefir from this milk is excellent and enables me to drink a good portion daily and stay low carb. Store bought kefir does not have the health benefits to the degree of kefir made at home, and it has a higher lactose content. It's very easy to make, and one can have a batch in 24 hours.

I also noticed a2 (brand) in stock at the same store, so I'll give that a try as well. I stayed away at first because I didn't want an ultra-pasteurized milk. I'm sure it will make a good kefir.

By the way, I found an article by Chris Kresser about the health benefits of kefir: https://chriskresser.com/kefir-the-...aleo-superfood/, and he was chastised by Loren Cordain, apparently for venturing too far from the Paleo reservation. Most of Cordain's arguments were based on health issues with milk that is not A2, and is produced by large farms that feed grains and administer hormones rBST, rBGH to the cows. That argument doesn't wash with organic A2 milk from grass fed cows.

Here's the link to Snowville Creamery with a good video introducing the dairy:
