Kirkland Signature Grass-Fed Butter
You can find this Kirkland Signature Grass-Fed Butter in all stores Nationwide. It’s a 2-pound pack of salted butter made from 95% grass-fed butter.
Grass-Fed Butter was a brand new Costco product added to the Kirkland Signature line in the first half of 2021. The flavor and health benefits of grass-fed butter need to introduction…and this comes much anticipated following the mass popularity of Kerrygold Irish Butter, which is also sold at Costco. See the Kerrygold vs. Kirkland Grass Fed Butter price comparison below!
Our Review
We buy this butter regularly, and recommend it. With just two ingredients, we love this simple, grass-fed butter! Kudos for this great addition to the Kirkland Signature brand of products. It’s also delicious, and much more affordable than the Kerrygold. Admittedly, when Kerrygold is on sale, I do stock up on it…and we use this in between. In my experience, there are as many who prefer the Kirkland as who prefer Kerrygold…in the end its a personal preference so if you’ve been wondering if you should try it I would say enthusiastically to give it a try.
When Costco first launched the Kirkland Grass Fed Butter it didn’t have measurement markings on the blocks of butter…that has been resolved!! There are now tablespoon markings on the Costco grass fed butter bricks!
Many are hoping it will come in an organic version and an unsalted version, but we’ve seen neither to date.
We think the grass fed Costco butter is at a particularly affordable price point for the category, and we do appreciate that the reasonable cost makes this more accessible to more Costco members.
Who Makes Kirkland Signature Grass Fed Butter?
The Kirkland Grass-Fed Butter from Costco is manufactured by Westland Milk Products in New Zealand. While Costco doesn’t often reveal the private label manufacturers, the supplier of this popular Costco product was recently revealed by Costco.
The fresh milk used to make the Costco house branded grass fed butter comes from 400 family farms on the West Coast of New Zealand. Westland has stated that the cows are fed at least a 95% grass fed diet – and only when fresh grass is not available, the cows may be supplemented with dried grass or grain. When they’re fed grain it is non-GMO and does not contain growth hormones (both are banned in farming in New Zealand).
Westland Milk Products was acquired in 2019 by China’s largest dairy company, Inner Mongolia Yili Industrial Group.

Why Grass Fed Butter?
We know that the nutritional content of meat changes dramatically based on what we feed an animal. Well, the same concept applies to butter, and thus grass-fed butter is packed with nutrients and health benefits. Additionally, the vast majority of people simply like it better for it’s flavor.
Pasture-Raised vs. Grass-Fed vs. Organic
The terms grass-fed and pasture-raised and organic can be be confusing. Wouldn’t cows eat grass in a pasture? Farmers don’t put pesticides on pastures do they? So it’s the same thing, right? These can all overlap, but aren’t necessarily one and the same. Like many food labeling “things” these have very specific meanings…here you go:
- Grass-fed means the cows’ food is grass – it refers to their diet and what they eat
- Pasture-raised means the cows roam free in pasture – it refers to where they live and spend time
- Organic means the cow’s grain was organic and the cow wasn’t exposed to pesticides or GMOs – it refers to their diet

Generally speaking New Zealand has the BEST standards worldwide for raising cows and dairy products. My ex is from there. They do not use toxic feed, never have as far as I know. This artcile should help clarify that New Zealand Dairy does not need the label to read Organic. https://milkio.co.nz/grass-fed-butter-nz/
I just read a report of tests conducted at an EPA certified lab. Results of Kirkland as well as KerryGold butter showed so called forever chemicals present in the wrapping. Any info on this or exposure amount?
I heard about Kerrygold wrappers a long time ago – it was removed from the store for a period then came back (as I understand it, with a new and compliant wrapper). I have heard questions about the Kirkland wrapper but have never seen any report or verifiable claim that there is anything in the wrapper that poses a danger – in general Costco will go leaps and bounds above what other retailers do to alert consumers when something is recalled, or poses a danger – and I’ve never seen or heard anything about it from them (I buy this product regularly). That said…I’m not Costco and I’m definitely not an authority on this I might suggest you visit costco.com and on the Customer Service page you should see a chat option, maybe you can inquire with them directly to get a more official answer. If you do learn more about this please share with me, I’d love to know too!! Thanks for sharing!!
I was just told that they are now mixing in vegetable oil with this butter, but not putting it on the label. Is that true? And would they risk their reputation and probably a huge fine if it were true.
I haven’t heard that rumor. I’ll look into it, but personally I would give Costco the benefit of the doubt on this one – because just as you said it would risk their very respected Kirkland Signature brand to what, save a few dollars on one product plus possibly face fines or other expensive legal work to remedy it. That being said, I’m not a spokesperson for Costco or KS, that’s just my reaction to hearing it…but I suppose as the saying goes…anything is possible?
Does anybody know if some or all of the grain component includes wheat, barley, or rye? On the website it says it is “gluten free”, but I have learned from experience that you can’t always trust that. There was another New Zealand grass-fed butter that Trader Joe’s carried (now discontinued, boo) that was 96-99% grass-fed, but no explanation of the grains, and I did fine on it. I can’t seem to find any more information about the Costco butter.
This post gets a lot of readers/commenters and I hope someone can help answer this – I wish I knew more about it and could help! Sometimes I find that folks on reddit have a lot of inside info (or speculation) about who the manufacturers are of Kirkland Signature products, maybe someone in the Costco group has some ideas about who makes it that might help you in your research?
This organic butter is the most non organic food I have ever eaten. This butter has been sitting in our butter dish for the better part of a week and still has not softened up at all. It’s like cutting a cold cube fresh from the fridge. The Kerry Gold gets soft after 2 hours. I am not sure what radiation cows they are using in New Zealand but I will not be buying this butter again.
I haven’t been able to find an organic version of this – did you maybe buy a different product?
It’s not organic. It’s just grass fed (95%). Would love to see an organic version, too!
It would be good to know the % or milligrams of omega 3
I have been looking for this new 95% grass-fed butter by Kirkland and have had no luck in my local costco’s.
Can you tell me in which states are they carried? I live in Pennsylvania. I even tried to order it online. No luck.
Please help. Thx.
In truth, I buy the Kerrygold Butter when it’s on sale and stock up – but now that you mention it I’m not sure I’ve seen the Kirkland one recently. I’ll look next time I’m in my store and see if we have it. Perhaps it out of stock. I’ll have to look though!
Thanks! I would love to know if you find it. My family would like to compare it to Kerrygold.
Hi Tracy! I found it in my store this week. I hope it’s back in stock for you soon!
Kirkland is a brand name used by Costco. Costco has a few Kirkland brands of butter but the 95% grass fed is called “Kirkland New Zealand Butter” which you can only buy at Costco
Southern California Carrie’s it. I alternate between this one and the Kerrygold Irish butter.
For me, it’s all about the taste. We tried Kerrygold years ago for health reasons but we love it because of the taste and texture. We would have to be really poor before we went to anything else. So now enter the new Kirkland grass fed butter from New Zealand. When I saw it my hopes were high. I pretty much love anything Costco puts their Kirkland brand on. And it was $2.00 (20%) cheaper than the Kerrygold. So I put a box in the cart to give it a try, along with our usual amount of Kerrygold. We are in the middle of consuming it right now and I must say I am very disappointed in it. Not only doesn’t it have that delicious buttery taste, but it is hard at room temperature. I have to put a pat on my toast/bread and then put it in the microwave to get it soft enough to spread without ripping the bread. I can’t wait till it’s gone and I’m so glad we didn’t leave our beloved Kerrygold behind at the store.
does this come in UNSALTED as well
I have not seen unsalted in-store before. The Kerrygold Grass-Fed Butter does come in both salted and unsalted though.

I would like to know the butterfat percentage in Kirkland grass fed butter. Kirkland signature butter is 80% butterfat which is the standard in the U.S. The standard in Europe is at least 83-85 % butterfat. The more butterfat, the better the butter tastes and dairies control the butterfat content when they centrifuge to separate the milk from the cream; so the information should be available. Kirkland grass fed butter definitely tastes better that Kirkland’s signature butter and is worth it just for that. I wonder how much of the taste difference is because the grass fed butter is wrapped in foil which better protects it from absorbing outside flavors. Their signature butter is wrapped in wax paper.
Are the cows treated with rBST? The packaging doesn’t say. If so, they have probably been given antibiotics since rBST causes more stress on the cows.
Is the grain fed to the cows organic? You give the definition of organic above, but don’t say the grain fed to the cows is organic.The packaging doesn’t say, just grain from local farms. If not, it is probably treated with glyphosate and other pesticides.
I too wish it was disclosed… I’m a food reviewer/reporter and not the manufacturer – just to make sure we’re on the same page 🙂 If you find out PLEASE let me know those answers too. My guess is that they are not treated with rBST but that the grain is not certified organic…just my guesses. I’m sorry I can’t help answer those!

Here’s my problem with the butter, there are no measurement marks on it to use for baking!
True! I find the marks on Kerrygold not ideal but they are certainly helpful in comparison to none. I hope they add them soon!
Right?! I thought so was going crazy! Ugh.
YES WE HAVE THE SAME PROBLEM
CANNOT MEASURE THE BUTTER BY THE TICK MARKS ON THE SIDE LIKE WE’VE BECOME ACCUSTOMED TO USING TO MEASURE THE PROPER AMOUNT OF BUTTER TO USE.
PLEASE FIX…
Also will you please specify the content of the 5% feed assuring it has no growth hormone nor glyphosate.
Thank you!
Kirkland grassfed butter is sadly grain finished, it kills all the goodness.
Grain finishing only happens in meat processing, you can’t grain finish butter. A cows diet will vary seasonally, but when a cow is grassfed on pasture for 365 days there is goodness for 365 days.
Grain is mixed with palm oil. Not good.
Palm oils are used in everything from engine fuel to lotion, pet food and in our processed foods. Not comfortable feeding our childern products containg palm oils, or even soy products.
Read read read your labels.
I have a feeling they are mix fed too but how did you figure that out?
I am very interested in the vitamin K2 content in Kirkland Monterey Jack cheese. Cows that are grass-fed produce high Vit K2 in their milk. I see your beef patties are grass-fed, so is your butter, but there is no information on the cheese. Vitamin K2 is very important in metabolizing Vit D, and without Vit D, calcium is not metabolized. It turns out that K2 and Vit D should be seen as co-vitamins for calcium absorption for strong bones and teeth. I would buy Kirkland Monterey Jack cheese if it is grass-fed.
Few people understand the synergy between Vit D & Vit K2. We could prevent much suffering if people understood how they work together to move calcium for appropriate use/repair then back to storage in the bone. Thanks for advancing the conversation Christine.
