Costco Kirkland Signature Grass-Fed Butter Review

Costco is carrying a new Kirkland Signature Grass-Fed Butter that’s cheaper than its beloved competitor Kerrygold. The butter is made with cream from cows that graze on the lush green pastures of New Zealand all year. Find out why I think the taste is worth making the switch from Kerrygold to Kirkland.

Other butters from Costco are the Kirkland Signature Mixed Nut Butter with Seeds, Kirkland Signature Natural Peanut Butter, Kirkland Signature Creamy Almond Butter and the Pisti Spreadable Pistachio Cream.

Location in Store

We found this butter in Kona, Hawaii in the refrigerated section near the cheese. The item number is 1424237.

Amazing on toast!

Taste

This is probably the best butter I’ve ever had and I’m someone who loves butter and uses it on everything. If you’ve had Kerrygold butter, this is similar but tastier in my opinion, I find it a lot more flavorful. As soon as you open the butter, you’ll notice it has a deeper, brighter yellow hue compared to regular North American butter.

You can see how nice and bright the color of the butter is.

The flavor of the butter is extremely creamy, smooth and just really buttery. It’s not too salty and the sodium content is actually less than Kerrygold. The butter is made with fresh cream from cows who graze on the pastures of New Zealand and the cows have a 95% grass fed diet.

Very creamy and smooth!

We used this mainly for breakfasts in Hawaii and everyone really enjoyed the butter on their toast and in eggs. My toddler really seemed to enjoy it on her pancakes and waffles too.

Cost

The box comes with four eight-ounce bars of butter and we paid $12.01 USD for the box. This is really reasonable and cheaper than Kerrygold butter.

Convenience

The butter needs to be kept refrigerated and the best before date is about six months from when we purchased it. There are four individually packaged blocks of butter in the box. I would absolutely recommend this for baking, I bet it would make amazing cookies, butter tarts or croissants!

I wouldn’t leave the butter out on a butter dish for more than a few days without refrigerating it. You really notice how good the butter is and the flavor of it when you simply spread it on a piece of toast or scone.

  1. I would love to try this butter but, Unfortunately because of the dairy cartel and our government overlords this butter cannot be sold in Canada.

    • If you or your family were dairy farmers, you probably wouldn’t think that way. Canada’s dairy regulations prevent an influx of inferior products from countries where labour is cheap which drops prices. It helps our farmers to earn a decent living and support their families. Don’t get me wrong, I too would love to have this butter but not at the expense of our high quality dairy industry.

      • I would think that if there were a problem with it and people started to get sick from it, Costco, which has over 850 locations across the world, would definitely stop selling it! Therefore I don’t believe there’s anything to worry about if you do buy it! This is not some mom and Pop store! When they buy butter it’s by the thousands of pounds, no doubt!

        • Sorry but that wasn’t my point. The government wants to protect our dairy business from an influx of non Canadian products, whether high or low quality. They put a tariff on out of country items to prevent them undercutting our local farmers.

  2. I saw a green wrapped Kirkland butter at River Cree Costco but can remember what it was called exactly. It was so busy this Saturday past that I got tired of waiting my turn for that particular cooler and forgot to go back😂
