Why Sheep Milk Matters—and Why It’s So Hard to Make
Sheep dairying might sound a little quirky—maybe even crazy—but at Green Dirt Farm, it’s the heart of everything we do. From the award-winning cheeses we craft to the regenerative pastures we tend, sheep milk is what sets our dairy apart. And while the U.S. is still catching up, people have been milking sheep for thousands of years.
Here’s what makes sheep milk so special, why it’s rare (and pricey), and how our flock came to be—through passion, persistence, and yes, a few harebrained ideas along the way.
Sheep Dairying Has Ancient Roots
In southern and eastern Europe, sheep dairying has been a way of life for centuries. Some of the world’s most beloved cheeses—Roquefort, Manchego, Pecorino—all start with sheep milk.
But here in the U.S., commercial sheep dairying didn’t really take off until the early 1990s, when a handful of pioneering farmers imported the first dairy sheep to kickstart America’s sheep milk artisan cheese movement. We joined that movement in 2002—way before most Americans had even heard of sheep milk.
What Makes Sheep Milk So Special?
So why sheep milk? Why not just stick with cows or goats?
We get asked this all the time. The truth is, sheep milk has qualities you just can’t find anywhere else.
1. Rich, clean flavor
Sheep milk tastes naturally sweet and creamy—without those goaty notes some people shy away from. It ages beautifully too, developing deep caramel and nutty flavors in cheeses like our Prairie Tomme and Dirt Lover.
2. Luxurious texture
Since sheep milk has more solids than cow or goat milk, you get:
- naturally thick yogurt
- silky cheeses
- an unmatched richness in every application
It even makes incredible coffee creamer—no additives needed.
3. Easier to digest
Sheep milk proteins are different from cow’s milk proteins, which makes it easier on the stomach for many people with cow milk intolerances. It’s also rich in medium and short-chain fatty acids—the kind that are better for your heart than the long-chain fats you get in cow milk.
4. Higher in nutrients
Sheep milk has nearly double the calcium of cow milk, plus naturally higher levels of protein, vitamins, and minerals.
Bottom line? Sheep milk is a delicious, nutrient-packed alternative if you’re looking for something both flavorful and easier on your body.
Why Is Sheep Milk So Rare—and So Expensive?
If sheep milk is so great, why isn’t it everywhere?
Simple answer: economics.
- A really good dairy ewe gives you about 4–6 pounds of milk per day.
- A dairy cow? She can produce 70+ pounds a day in confinement systems.
Sheep also need excellent pasture, pricier feed, and a lot of hands-on care. Small-scale, pasture-based dairies like ours invest in regenerative grazing, animal welfare, and on-farm cheesemaking—all of which cost more but make a huge difference in quality.
So yes, our sheep milk cheeses cost more. But they also give you:
- unparalleled flavor
- better digestibility
- nutrient density
- craftsmanship you can taste
And for a lot of people, that difference really matters.
Our (Sometimes Lunatic) Start at Green Dirt Farm
When I started Green Dirt Farm in 2002, I bought:
- twelve dairy ewes from Wisconsin
- twelve Gulf Coast ewes from Missouri
- and one (very busy) ram
My big idea? Crossbreed the hardy, wild Gulf Coast sheep with imported dairy ewes to create a parasite-resistant dairy sheep.
It was… ambitious.
Gulf Coast Sheep: Great Genetics, Impossible Attitude
Gulf Coast sheep survived 400+ years in the wild pine barrens of the Gulf states after Spanish explorers left them behind. Over time, they became:
- highly parasite-resistant
- extremely hardy
- extremely feral
Turns out, that last one’s a real problem when you’re trying to milk an animal.
Dairy sheep need to be calm, comfortable around people, and willing to walk into a milking parlor. Gulf Coast sheep? They wanted nothing to do with it. By 2007, the writing was on the wall—we needed real, purpose-bred dairy sheep.
A National Problem: Not Enough Dairy Sheep Genetics
But there was a problem: the U.S. had almost no high-quality dairy sheep genetics. Disease outbreaks in Europe in the 1990s closed the border to new ruminant imports. American farmers were stuck with just a few early imports—good sheep, sure, but nowhere near the high-production lines available in Europe.
Without better genetics, a lot of U.S. sheep dairies struggled to make it work and eventually had to close.
How DSANA Helped Save Sheep Dairying in the U.S.
Thankfully, the Dairy Sheep Association of North America (DSANA) stepped in. Led by Tom Clark of Old Chatham Sheepherding Company, DSANA spent years working with the USDA to bring in frozen semen from France’s elite Lacaune dairy sheep—the same breed that makes Roquefort possible.
For over a century, Lacaunes have been carefully bred for:
- outstanding milk yield
- strong udders
- excellent milk quality
- good temperaments
By 2017, U.S. farmers—including us—finally had access to these genetics.
How Our Flock Improved—Thanks to Science and Eliza
We did our first breeding with Lacaune semen in 2017. By then, my daughter Eliza Spertus had taken over managing our dairy flock.
Through careful breeding, meticulous record-keeping, and years of hard work, Eliza more than doubled our flock’s average milk production.
This kind of improvement is game-changing—not just for us, but for the future of sheep dairying in the U.S.
As more farmers get access to better genetics and people keep looking for flavorful, earth-friendly alternatives, sheep milk products will become more and more accessible across the country.
