Selective Breeding, Healthier Herds

The Journey to A2/A2

If you’ve heard of A2/A2 milk, you’ve probably also heard claims that it’s “easier on the stomach.” That’s true — and it all comes down to a tiny difference in milk proteins that traces back thousands of years.

But the journey to A2/A2 milk isn’t just about digestion. It’s a story of cow genetics, selective breeding, and thoughtful sourcing — from farm to bottle.

At Snowville Creamery, we don’t own cows ourselves. Instead, we work with dedicated local farmers who care deeply about their animals and their milk. Together, we’ve made the choice to exclusively source milk from A2/A2 herds — and that’s a commitment rooted in science, transparency, and a whole lot of care.

🧬 The Beta-Casein Difference

All cow's milk contains a protein called beta-casein — and there are two types that matter: A1 and A2.

Most dairy cows in the U.S. produce a mix of A1 and A2 proteins. But emerging research suggests that A1 may be harder to digest for some people, possibly contributing to bloating or discomfort — even if they aren’t lactose intolerant.

Cows that produce only the A2 type of beta-casein are known as A2/A2 cows, and their milk is naturally free from A1.

🌍 A2: The Original Cow

Here’s something surprising: A2 isn’t new — it’s ancient.

Early domesticated cows all produced A2 milk. The A1 gene appeared as a natural mutation in European dairy herds thousands of years ago and slowly became more common as dairy farming evolved.

Over the past two decades, some farmers and creameries have worked to selectively breed A2 cows through natural methods, choosing breeding stock based on genetic testing. The result? More herds capable of producing 100% A2/A2 milk — and a growing interest from people who want a gentler, more traditional kind of dairy.

🤝 Our Role in the A2/A2 Journey

At Snowville, we made a clear choice:

If we’re going to offer the most digestible, high-integrity milk possible, it has to come from A2/A2 cows.

We don’t breed cows ourselves, but we’ve spent years working with partner farmers who share our values — and who are committed to raising cows that produce only A2 milk.

We also ensure that:

• Every herd is genetically tested to confirm A2/A2 beta-casein

• Cows are grass-fed

• Milk is lower-temp pasteurized and minimally processed, preserving nutrition and taste

That means when you pick up a bottle of Snowville milk, cheese, yogurt, or buttermilk, you can trust that it’s 100% A2/A2 from the farm up.

🥛 A2/A2 and the Future of Dairy

The evolution of A2/A2 milk is just one part of a broader shift in food: a return to simpler, more digestible, and more transparent choices.

By working with farmers who embrace thoughtful herd management, we’re proud to offer dairy that’s not only better for your belly — but better in spirit, too.

Because sometimes, going forward starts with going back — to the way milk used to be.
