It seems that there’s a lot of confusion and even misinformation out there about A2 milk. I’m hoping to bring some light to the topic. How can you be absolutely certain the milk is 100% A2?

It’s NOT the breed of the cow. It’s NOT the fat content. It’s NOT whether it’s raw or homogenized. It’s NOT the nutritional content. It’s NOT what the cow is fed. It’s NOT how a cow lives.

The “A2” in A2 milk refers to the type of beta-casein protein in the milk.

It’s that simple, and it’s absolutely objective. It’s not like Grade A and Grade B maple syrup, which is certainly subjective.

The only way to tell if a cow produces 100% A2 milk is via a genetic test.

It’s a simple test done with a hair sample from a cow’s tail. You send it to a lab, and they send back the results. The test result tells you if the cow produces 100% A1, A1/A2, or 100% A2 milk. See some examples of what the test results look like below.

It’s black and white. There is no wiggle room.

The farmer tests every cow to determine what type of milk it produces. Only cows that produce 100% A2 milk are in the milking herd.

You might be asking, why do cows produce different types of protein? And, why would I want to drink A2 milk? Those are great questions!

You see, all other mammals - humans, goats, sheep, buffalo, whales, bears, pigs, platypuses, etc - produce 100% A2 milk. But...

A few thousand years ago in Europe, cows underwent a genetic mutation. This mutation made them produce a new type of beta-casein protein - A1.

Genetic mutations generally happen under stress. Perhaps it was a switch to an unnatural feed (like leftover brewer’s grain) or a change in environment (cows living indoors or in cities) that prompted the mutation. We know a mutation happened but we may never know why.

Those European cows made their way to the United States. Now, basically all American milk is A1/A2 milk. On the other side of the world in Asia, cows were unaffected.

I’ve heard many stories about people from India or China coming to the United States and developing chronic digestive issues. When they switch to A2 milk, the problems go away.

Similarly, I’ve heard stories of children’s behavior improving when they switch to A2 milk. Farmer Aaron himself had this experience. When his fourth child Hannah was a baby, she had terrible colic and had issues breastfeeding. Aaron’s wife Rebecca made her formula. When she switched to A2 milk in the formula, Hannah was much happier. This is what inspired him to produce 100% A2 milk for others!

It seems that some people are intolerant to A1 beta-casein protein. It seems that 100% A2 milk may be more digestible.

To be clear, this does not have to do with lactose intolerance. Lactose is milk sugar. It has to do with A1 protein intolerance. It seems that some bodies cannot digest it properly.

More research certainly needs to be done on the A1/A2 milk debate. I want to know more! For example, I’ve read that the A1 beta-casein protein may only be a problem when the milk is pasteurized…?

If you’d like to learn more about A2 milk, I suggest reading the book The Devil in the Milk.

What’s really in a grocery store turkey?

It’s that time of year again—the turkey takes center stage. Whether it’s Thanksgiving, Christmas, or just a Sunday family dinner, a golden-brown bird is often the star of the show. But if you’re grabbing a conventional turkey from the grocery store, you might be wondering: what’s actually in it besides turkey? Why not add weird stuff to our holiday dinner? Many conventional turkeys are “enhanced” before they even make it to the freezer aisle. That usually means they’ve been injected with a solution of water, salt, and sometimes sugar or broth. It’s meant to keep the meat "moist and flavorful", but it also means your turkey may contain up to 15% of stuff that isn’t turkey. Always check the fine print on the label—you might be paying turkey prices for salty water. I sure hope you like your turkey with a side of salt! Those injections can leave a grocery store turkey surprisingly high in sodium. And when you see “natural flavorings” or “seasonings” on the label, it isn’t always just herbs and spices—it can also mean more hidden salt and flavor enhancers. So what exactly are these “boosters”? Think modified food starch for texture, “natural flavorings,” caramel coloring, and sometimes even MSG for that extra hit of savory flavor.Here’s the kicker: take a look at this turkey below—it’s sold by a major brand and proudly labeled ALL NATURAL. But read closely, and you’ll see it actually contains about 4% “other ingredients” that aren’t clearly listed. Makes you wonder, right? Turns out the real stuffing happens long before Thanksgiving—it’s all corn, soy, and unnatural junk. Conventional turkeys are typically raised on large farms where antibiotics may be used to prevent illness in crowded conditions. The USDA regulates withdrawal periods before processing (meaning the birds shouldn’t have antibiotics in their system at slaughter). So does that mean the birds really aren't antibiotic free after all? How confusing for the consumer! As for what the conventional turkeys are fed: Grains:Corn, wheat, and barley aren’t just wholesome-sounding grains—they’re the cheapest way to pack calories into a turkey, fueling rapid growth. Efficiency, not nutrition, is the goal here.Seed Oils:Soy, canola, and flaxseed are tossed in, not out of kindness, but to boost fat content and keep growth on track. Soy especially dominates, since it’s cheap and plentiful—most of it genetically modified. So these turkeys are definitely not low PUFA.Protein sources:Turkeys grow fast, and that means they need protein—lots of it. Beyond soy, feed mills mix in other plant-based proteins to supercharge growth in young poults. The formula isn’t about balance or natural diets; it’s about pushing birds to market weight as quickly as possible. Seed oils, sugar and more, OH MY! Certain “self-basting” turkeys may also contain a touch of sugar or dextrose, oils, or even phosphates to help retain moisture during roasting. My gosh this list keeps going on and on... And the star of the show... Conventional turkeys are genetically bred to grow quickly and large, especially in the breast area—because that’s what most shoppers want. It’s something Big Ag has down to a science: decades of selective breeding for size and speed at the expense of health and flavor. The result? A bird designed for profit margins, not taste. Compared to wild or heritage turkeys, today’s supermarket turkeys are bland, bloated, and bred to fit industry demand, not the dinner table. These turkeys don’t look much like wild turkeys anymore.

Does exploding milk kefir mean it's bad? Not necessarily.

We get this question from customers on the regular --> "My kefir exploded. Is that normal? Does that mean it's bad?" The answer? Bubbly volcanic kefir is 100% ok. Kefir is known as the "champagne of dairy" for a reason! In case you haven't tried it, milk kefir is a fermented drink made with milk. It's similar in taste to yogurt (a little stronger in my opinion) but has more probiotics. As I've heard it said, yogurt is good for cleansing the gut. Kefir, on the other hand, adds to the gut. People working to heal or enhance the function of their digestive system often turn to kefir as part of this process. Even though kefir has been around for thousands of years, it seems that there's still some mystery around it. I mean, it's just not as popular as yogurt, particularly in the US. Bubbles in kefir are a natural part of the fermentation process. To make kefir, you need to add culture to milk. Different from yogurt culture, which is strains of probiotic bacteria only, kefir is a symbiotic culture of probiotic bacteria AND yeast. Once the culture is added, you let it ferment at room temp. The culture eats up the milk sugar (AKA lactose), creates bubbles (AKA CO2), and grows more of the culture. When you get bubbly kefir, that's a sure sign that it's fermented. It's also a sure sign that it's probiotic. After all, the more CO2, the more eating and duplicating the bacteria and yeast did. After we make it, kefir will continue to ferment. It will happen more rapidly at room temp and more slowly in the fridge. But, it's still happening. More and more bubbles are created over time. And, if that container is air tight, lots of pressure builds up within the container. If you don't open the kefir and it's super fermented, there is the potential for lots of bubbles upon opening. Here's a short video of a kefir explosion: And, here's a little story about the worst kefir explosion I've heard of. Years ago, we used to sell blueberry kefir. With that added sugary fruit in the end, the culture would really take off. A customer sent us a picture of blueberry kefir on her kitchen ceiling!! It really exploded. I wish I could have been there to help her clean it up! Open slowly or burp kefir to stop it from exploding. Not a fan of your kefir exploding? Thankfully, there's an easy solution. Open slowly. Simply crack the lid a little, and let the gas escape before opening all the way. You could even burp your kefir every day or two in the fridge to prevent it from getting too bubbly. The only way to stop kefir from fermenting and creating more bubbles is to freeze it. However, I don't recommend that. First off, kefir tends to get clumpy when thawed. Second, there's some probiotic loss when freezing. The longer it's frozen, the more probiotic loss. If you need to freeze kefir for later, I don't recommend freezing it for more than 3 months. You know kefir really went bad by the smell and look. When you make kefir with raw milk, it's slowly turning into kefir cheese. So when I say it goes "bad", it's really just knowing when it's too sour or pungent to palate. It's not necessarily a safety issue. Here are two things to look for: Putrid Smell: OK, kefir smells funky, even good kefir. But, especially if you've been drinking kefir for a while, you should be able to tell when it smells putrid. Like, you absolutely aren't able to consume it.Massive Separation: A little separation in kefir is normal. You will see the whey (a yellowish liquid) separate from the thicker white part. But, if it's all separated, and the white creamy part has turned into a mass of clumps, it's probably not the best to consume anymore. *Side note: I think this is why most kefir comes in a container that's NOT clear. When you make kefir with pasteurized milk, it's a different story. Since there isn't a natural community of microorganisms that are regulating themselves, it has the potential to go bad in a dangerous way. In addition to the signs listed above, here's one more thing to look for: Visible Mold: Especially green, orange, red, or black mold, which is a clear indication that the kefir is bad and should be tossed. All in all, this is really about trusting your gut and being connected to your food. How bubbly has your kefir been? Have you ever had it explode? Do you drink kefir for its yumminess or probiotic benefits? I'd love to hear from you. Comment below to share your thoughts with our community (no account required).
