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.

Does varying yolk color affect the flavor of honest eggs?

As you know, we don't add any color to our feed. This is why our pastured corn & soy free eggs are called "honest yolk eggs". "Color" includes unnatural stuff like dyes as well as natural stuff like marigold and paprika. Nearly all egg farmers nowadays do this... even the natural ones. Why? People demand consistent color yolks, thinking it means a certain quality. Little do most know, yolk color is superficial now. At Miller's, we know this for a fact. Curiosity made us to send our eggs for testing, and there was zero nutritional difference in our orange vs yellow yolk eggs. What mattered most was the farming practices and quality of the feed, and our eggs came out on top for most tests. We really love having varying yolk color. It's an indicator of what the birds are eating. It tells our farmers how their pasture is doing. If the plants are too mature, not diverse enough, it's too wet or dry, or if chickens aren't eating the pasture, we'll see that with the yolk color! Now, we've had an array of responses since we removed the color from our feed. One baffling one is --- the light colored yolks don't taste as good as the dark colored yolks. Is this true? I mean, removing the color is only a superficial change. It shouldn't affect the flavor. Well, we needed to find out. So... we did a blind tasting on the farm a few weeks ago. Here's what that looked like: The results? The whole team agreed -- all eggs tasted the same! The biggest factor affecting egg flavor was the yolk to white ratio. The more yolk, the more flavor. It's spring, and our hens are out on pasture 100% of the time. An egg develops for about 6 weeks inside a chicken, so it takes some time. But... you should start to see darker yolks now. Have you noticed a change in yolk color? Have you noticed a flavor change? Would you prefer consistent colored yolks or honest yolks? I'd love to hear from you.

See a volcano of pickles! The pluses and minuses of natural ferments.

A customer shared his farm food order with us on Instagram. Thanks for sharing, Nick! It included this amazing video of the volcano that can erupt from our fermented pickles: What's going on here? Why so many bubbles? Conventional pasteurized vinegar pickles (you know, the kind that are considered "normal") don't bubble at all. What you're seeing is the fermentation. When fermented pickles are made, it's a very simple process. The following is mixed in a jar: Cucumbers, well water, celery seed, mustard seed, dill, garlic, Celtic sea salt, and whey. Then, the jar sits with a loose lid for 3-7 days, until it's done fermenting. The seeds and herbs are in there for flavor only. The cucumbers, water, salt, and whey are what make the magic happen. Note that there is no powdered culture added. Yes, whey is added and it has probiotics, but it simply helps jumpstart the ferment. Even without the whey, those pickles would ferment. It would just take a little longer. This is because raw veggies naturally have lactic acid bacteria (LAB) in them. When you mix them with water and salt, it creates the perfect environment for them to grow. Pretty cool, right? The living microbiology (the LAB) grow and multiply. They eat the naturally occurring sugars and starches in the cucumbers and produce CO2, a gas. The fermentation carbonated the pickle brine! The fermentation made the volcano! It's also a sure sign that there's plenty of good probiotic stuff for your gut in that jar. The white stuff is yeast (most likely KAHM yeast). Another thing to notice in the jar is how the liquid is whitish, not clear. There's nothing unsafe about it. Yes, you can eat it! It's a natural part of fermentation. You see, KAHM yeast thrives in acidic environments. As that probiotic goodness ferments and creates CO2, it also creates lactic acid. The lactic acid not only gives pickles their distinct sour flavor but also makes the brine acidic. KAHM yeast is naturally in the air. It will land on a ferment and think "Gee, this would be a great home." And then it grows. It typically makes a film on the top of a ferment, but it can also sink to the bottom. With volcanic pickles, it gets all mixed up in the brine and will eventually settle. Fermented veggies are an acquired taste. Nick, who shared the volcanic pickles video, reported that: "The pickles are absolutely delicious. I love them!" But... we sometimes get complaints about the flavor of the pickles and the white stuff. Is Nick's palate simply more accustomed to ferments? Were some jars of pickles actually off? It's really hard to say... especially when you're not there smelling and tasting it yourself. What I do know is that fermented veggies are an acquired taste. They're very different from the distinct pasteurized vinegar pickle flavor you likely grew up with. Fermented pickles have umami to them (think about that "weird" flavor in miso or a very sharp aged cheese). They have a lot of tang. They can even taste metallic. Some may feel a burn on their tongue (that's the lactic acid by the way). You may want to try making some at home (as I said before, it's pretty easy). That way, you can taste the flavor throughout the fermentation process and put it in the fridge when you think they're just right. Fermented veggies can last months in the fridge with proper maintenance. Here are a few tips to keep them in their best shape. Always store in the fridge. This will slow down the fermentation so they don't get overdone. If you leave them on the counter (especially pickles), they'll get quite sour and mushy pretty quickly. Never freeze ferments. They'll just get mushy. Make sure the veggies are always covered with brine. If the brine falls below the veggies, simply add more water and sea salt. So easy! If the veggies aren't covered, they can grow mold or dry out and become yucky. If there's too much KAHM yeast, remove it. KAHM yeast is perfectly safe to eat. However, it can have an off-putting flavor, especially when there's too much. If it's on the top of the brine, simply scoop it off. If it's all mixed up in the brine, let the jar sit for a day or two so it settles. Once it sinks to the bottom of the jar, you can remove the pickles and clean brine (leaving the white stuff at the bottom), clean the jar, and then put the pickles and brine back in. Voila! With this in mind, you might be wondering... Can ferments become unsafe? If a lacto-fermented veggie goes wrong, it will be pretty obvious. It may have a repulsive smell, flashy colors (like pink or black mold), or a foul flavor. While a normal ferment should have a sour, tangy smell, a bad ferment will smell putrid or rotten. This can be a little tricky, especially if you're new to ferments. The flavor can be wild! Often you simply need to trust your gut. Although getting used to ferments can take some time and know how, it's worth it. Why? They're just so darn good for your gut. They're packed with a range of lactic acid bacteria. Fermented veggies usually have bifidobacteria, too, which isn't prevalent in fermented dairy but is crucial for healthy digestion. When you have robust and healthy gut microbiology: The bad stuff simply can't grow. You're less likely to get sick. Your digestion is better overall, meaning that you get max nutrition from the food you eat.Your gut can better produce essential nutrients like short-chain fatty acids and vitamins B1, B9, B12, and K.You can experience less inflammation.Your gut-brain connection is better. You may find yourself in a better mood, with less stress. There's probably so much more, but those are the top ones for me! Do you eat or make ferments? Why or why not? Have you tried the pickles? What's your experience? I'd love to hear from you! Comment below (no account required - start typing for the guest option to appear) or contact us.
