Is Kerrygold Organic? What Their Grass-Fed Label Means

AvatarByEric Dawson Organic Food

Kerrygold is not certified organic. The Irish dairy brand built its reputation on grass-fed farming instead of organic status, and none of its butter, cheese, or milk products carry an organic seal. Cows on Kerrygold’s supplying farms graze on Irish pasture for about 312 days a year, then eat stored grass and grain during the winter months. That system overlaps with organic ideals since both favor pasture over confinement, yet Kerrygold operates under Ireland’s Sustainable Dairy Assurance Scheme and its own Grass-Fed Dairy Standard rather than an organic certification program. Buyers who want a certified organic dairy brand will need to look elsewhere.

Is Kerrygold Organic Certified?

No organic certification appears on Kerrygold packaging, and the company has never pursued one. Kerrygold instead promotes grass-fed farming as its primary credential, a strategy that lets it highlight pasture-based practices without going through the audits organic certification requires.

Ireland’s Sustainable Dairy Assurance Scheme governs the farms that supply Kerrygold, covering animal welfare, hygiene, land management, and emissions reduction. About 99 percent of the Irish farms in the Kerrygold supply chain are family owned, and farmers move cows between paddocks on a rotational grazing plan rather than keeping them on one fixed field. Grass-based systems like this tend to produce lower milk yields than intensive confinement farming, a tradeoff Kerrygold accepts as part of its pasture-first model.

Organic dairy certification in the United States typically requires a producer to document feed sourcing, prohibited substances, and land management practices for an outside auditor, then renew that certification every year. Kerrygold’s Sustainable Dairy Assurance Scheme runs on a different rule book entirely, built around grazing, welfare, and emissions rather than the organic standard, so the two programs stay separate even in places where their practices happen to overlap. Neither program substitutes for the other, and Kerrygold has kept its marketing focused on the grass-fed side of that divide.

What Does Kerrygold’s Grass-Fed Label Mean?

Kerrygold’s grass-fed label means the company’s cows eat fresh pasture grass for most of the year, with grain added only to fill nutritional gaps. Ireland’s Grass-Fed Dairy Standard sets the rules Kerrygold follows, and the brand states its cows eat a diet that is on average 95 percent grass.

That claim carries different weight depending on where it appears. Kerrygold’s European packaging leaves grass-fed language off entirely, because the claim is tightly regulated there and must be verified before a company can print it. American shoppers see the opposite situation. Grass-fed claims in the United States are not independently verified, ever since the U.S. Department of Agriculture dropped its official grass-fed definition in 2016 and said it lacked the authority to confirm whether such claims were truthful and not misleading. The gap in oversight lets Kerrygold and other brands print grass-fed language on U.S. packaging without a third party checking the math.

Ireland’s Grass-Fed Dairy Standard requires supplying farms to log grazing days and feed composition each year, which gives Kerrygold a paper trail behind its 95 percent figure even though that paperwork is not published for outside review the way an organic certifier’s audit would be. Shoppers are left to take the aggregate number on trust, since neither Kerrygold nor the standard body releases farm-by-farm data that would let an outsider recheck the math.

How Much of a Kerrygold Cow’s Diet Is Actually Grass?

Roughly 90 to 95 percent of a Kerrygold cow’s annual diet is grass, depending on whose number is used. Kerrygold’s own FAQ page states the figure at 95 percent, while an independent analysis from Live Simply calculates closer to 90 percent, based on the brand’s stated 312 grazing days per year. Both figures describe the same herd; they simply frame the math differently. Kerrygold’s number carries the weight of an official standard, though it also arrives without a published methodology explaining exactly how the 95 percent figure is calculated, which is why an outside estimate is worth keeping alongside it.

Aspect Kerrygold Status
Certified organic No
Grass-fed percentage About 95% (Kerrygold claim) or about 90% (independent calculation)
Days on pasture About 312 days per year
Winter supplementation About 44 days per year
Supplementary feed share of diet About 10%
GMO feed content About 3% of total annual diet
Family-owned farms 99% of suppliers
Governing standard Ireland’s Grass-Fed Dairy Standard plus SDAS
Organic certification held None

The math behind the 312-day figure is worth spelling out. Divide 312 grazing days by 365 days in a year and the result is about 85 percent, a lower number than either the 95 percent or 90 percent grass-fed figures Kerrygold and Live Simply cite. The difference comes down to what is being measured. Days-on-pasture counts only the days cows are physically grazing, while the grass-fed percentage measures diet composition, since stored silage and hay eaten during the other 44 days still count as grass in that calculation rather than as supplement.

Winter is when supplementation happens most. Cows graze fresh pasture for about 312 days a year, leaving roughly 44 days when farmers rely on stored silage, haylage, hay, and grain. Supplementary feed makes up about 10 percent of the annual diet overall, drawn mostly from Irish-grown wheat and barley, with smaller amounts of distillers grain, rapeseed, soy, and citrus pulp mixed in. Kerrygold and its Irish suppliers say every batch of supplementary feed meets European and national safety standards before it reaches a cow.

Genetically modified crops make up a small slice of that supplemental feed. About 20 to 25 percent of the grain supplement may come from genetically modified sources, which works out to roughly 3 percent of a cow’s total annual diet once the math is applied across the full year. Shoppers who want a dairy brand with zero GMO exposure in the feed chain will not find that guarantee from Kerrygold, though the exposure is smaller than the raw supplement percentage might suggest.

What Farming Standards Does Kerrygold Follow Instead of Organic Certification?

Kerrygold follows Ireland’s Sustainable Dairy Assurance Scheme rather than an organic program, and that scheme sets its own rules for welfare, hygiene, land use, and emissions. Farmers enrolled in the scheme commit to standards that Kerrygold’s marketing treats as a stand-in for the kind of assurance organic certification would normally provide.

Rotational Grazing and Family Farms

Rotational grazing means farmers move cows from paddock to paddock on a planned schedule instead of leaving them on one fixed field. The practice lets grass recover between grazing periods and keeps pasture quality higher through the growing season. About 99 percent of the farms supplying Kerrygold are family owned, a figure the company points to as evidence that its grass-fed model has not pushed out small operations in favor of industrial-scale dairies.

How Farms Handle Winter Feeding

Winter forces a shift away from fresh grazing, and farmers prepare for it months in advance. During the summer growing season, farmers harvest and store surplus grass as silage, haylage, or hay, building up a reserve large enough to carry the herd through the roughly 44 days a year when fresh pasture is not available. Stored forage keeps the diet grass-based even when cows are not standing in a field eating it directly.

Feed safety rules apply throughout that winter stretch as much as they do during the grazing season. Supplementary rations, including the wheat, barley, distillers grain, rapeseed, soy, and citrus pulp mentioned earlier, must meet European and national safety standards before reaching a cow, according to Kerrygold’s own FAQ page. Farmers coordinate the timing of stored forage and grain so the herd’s diet stays as close to grass-based as the calendar allows, even in the coldest months of the year.

Why Did a Lawsuit Challenge Kerrygold’s Grass-Fed Claims?

A class action lawsuit accused Kerrygold’s grass-fed marketing of being false, misleading, and deceptive, on the grounds that cows supplying the brand receive genetically modified and other grain rather than eating grass exclusively. The presiding court dismissed the case, ruling that the FDA has no legal definition for grass-fed claims to enforce against.

The dismissal traces back to a regulatory gap rather than a finding that Kerrygold’s marketing was accurate. Once the USDA dropped its grass-fed definition in 2016, no federal agency retained clear authority to police what a grass-fed label has to mean on a dairy product. Two sources frame the consequences differently. TruBeef Organic treats the withdrawal as an opening that lets companies make grass-fed claims without independent verification, while Green Oklahoma frames the same withdrawal as the specific reason lawsuits like the one against Kerrygold cannot succeed in court. Both readings rest on the same underlying fact, and neither contradicts the other, since they simply emphasize different consequences of one regulatory decision.

Plaintiffs in the case argued that shoppers reading Kerrygold’s grass-fed marketing would not expect genetically modified grain anywhere in the feed mix, and that the gap between expectation and practice made the label misleading. The court’s ruling did not weigh in on whether that expectation was reasonable. Its decision turned entirely on jurisdiction, since no federal agency currently defines grass-fed clearly enough for a court to measure Kerrygold’s marketing against it. That leaves the underlying question, whether the label misleads shoppers, unresolved rather than settled in Kerrygold’s favor.

How Does Kerrygold Compare to Organic Valley or Certified Grass-Fed Brands?

Kerrygold sits between conventional dairy and fully verified certification programs. Organic Valley, one of the best known organic dairy brands, also supplements cow diets with grain, which means Kerrygold is not unusual among pasture-focused brands for mixing some grain into an otherwise grass-heavy diet.

Shoppers who want a grass-fed claim backed by on-farm inspection have three certification bodies to look for instead: the American Grassfed Association, Global Animal Partnership at Step 4 or higher, and Animal Welfare Approved. Each of these groups sends inspectors to farms to verify grazing practices before allowing a producer to use their seal, a level of oversight the U.S. grass-fed market does not otherwise require.

None of that makes Kerrygold’s practices dishonest. It means the brand’s grass-fed claim rests on a standard it wrote for itself, verified internally rather than by an outside inspector with the power to pull certification. A shopper who wants Kerrygold‘s pasture story and does not mind the winter grain supplement has little reason to look elsewhere. Someone who wants a third party standing behind the label has a short, specific list of certifications to check for instead, and Kerrygold is not on it.

If I wanted organic dairy, I would not treat Kerrygold’s pasture system as a substitute for the organic seal. Its 90 to 95 percent grass-based diet is a strong pasture record, but it still allows grain supplementation and does not carry organic certification. I would choose Kerrygold over a conventional dairy product when pasture access is my main priority. But if I wanted the clearest assurance of either organic rules or an all-grass standard, I would choose a product with the relevant certification.

Frequently Asked Questions

Is Kerrygold 100 Percent Grass-Fed?

No, Kerrygold is not 100 percent grass-fed. Cows eat fresh pasture for about 312 days a year and switch to stored forage and grain supplements for the remaining roughly 44 days, which puts the diet at somewhere between 90 and 95 percent grass depending on whose calculation is used.

Does Kerrygold Use GMO Feed?

Yes, a small share of Kerrygold’s supplementary feed comes from genetically modified sources. About 20 to 25 percent of the grain supplement may be genetically modified, which works out to roughly 3 percent of a cow’s total annual diet once the full year is accounted for.

What Is the Difference Between Grass-Fed and Organic Dairy?

Grass-fed labels describe what a cow eats, while organic certification covers a broader set of rules, including feed sourcing, land management, and prohibited substances, verified by an accredited certifier. Kerrygold meets grass-fed style standards under Ireland’s own program but has not sought the organic certification that would apply the broader rule set.

Why Doesn’t Kerrygold Pursue Organic Certification?

Kerrygold has not published a stated reason for skipping organic certification. The company instead promotes its grass-fed pasture model and its membership in Ireland’s Sustainable Dairy Assurance Scheme as its main credentials, treating those programs as the primary story it tells shoppers.

How Can I Find a Certified Grass-Fed Dairy Brand?

Look for a seal from the American Grassfed Association, Global Animal Partnership at Step 4 or higher, or Animal Welfare Approved. These organizations inspect farms directly before granting certification, a level of independent verification that voluntary grass-fed claims in the United States do not otherwise require.

Kerrygold’s grass-fed story holds up reasonably well against the numbers behind it, even without an organic seal on the label. Shoppers who care specifically about organic certification should look elsewhere, but those who prioritize pasture-based farming and family-owned supply chains will find Kerrygold’s practices line up with what the brand advertises, supplementary grain and all.
