Who Makes Kirkland Butter in [currentyear]?

Unfortunately, we cannot say who makes Kirkland Signature Butter in [currentyear]. The reasoning is that no one has come forward to claim the butter, and also, the Kirkland Signature brand, and the company that owns this brand, Costco, have not yet released this information. However, there are theories that the butter comes from either Tillamook or Land O Lakes.

Keep reading if you would like to hear more about where Kirkland’s butter may come from, where you’re able to buy it, and more!

Does Kirkland Signature Have a Warehouse Where It Makes Its Own Butter?

The Kirkland Signature brand, surprisingly enough, doesn’t have its own factory where the products that it has to offer are made.

Instead, it outsources to other well-known companies and gets its goods from all around the world.

It can be hard to determine who makes Kirkland Signature brand products, such as its butter.

This is because Costco, the Kirkland Signature brand, and the company that makes the goods do not offer this information.

Usually, the only way that this information finds its way to the internet is when there is a recall for a certain product from the manufacturer, or there is an insider leak.

The reasoning behind keeping the identity of the manufacturer of its products a secret is that either party doesn’t want to lose out on sales.

Also, the Kirkland Signature brand is known for its low prices, and it’s hard to keep the prices so low if there’s competition on where the product is sold.

Of course, we can always make guesses as to which companies have the same butter by comparing flavors, textures, ingredients, colors, and more.

A few popular guesses are that it’s made by either Land O Lakes or Tillamook. Unfortunately, though, it’s hard to say for sure until the information is officially released.

Who Is Tillamook and Land O Lakes?

Both of these names may sound familiar, and for good reason, as they are both commonly found in the refrigerated dairy section of grocery stores.

The Land O Lakes Dairy Co-op was formed in 1921 with the belief that everything is better when they work together. In fact, currently, this company is working with over 1,600 dairy farmers.

Tillamook is known for doing things the way farm-owners have done things since 1909. The company cares for its farm-owners while the farm-owners care for their land and cows.

So, with so much care going into its milk, we are left with better quality products. Plus, the company uses the same simple recipe it has followed for over a century.

Where Can You Buy Kirkland Signature Butter?

Where Can You Buy Kirkland Signature Butter?

You can find Kirkland Signature Butter easily in your local Costco Wholesale store.

There, you will be able to locate either salted or unsalted butter in the freezer or refrigerated section.

In fact, you can even opt to order it online at Costco.com and have it shipped right to your front door, along with your other Costco purchases.

An added bonus to ordering online is you don’t need a Costco membership in order to shop. However, if you’re not a member, a 5% surcharge will be added to your final bill.

How Should You Store Kirkland Signature Butter?

There are many ways that you can choose to store your Kirkland Signature butter.

For one, you can store it at room temperature, as it’s made with pasteurized milk and contains a very small amount of water, which leads to lower chances of bacteria growth.

As well, it’s also made with salt, which as we know, is a preserving agent and makes it more shelf-stable.

Keeping the butter out of bright light, away from odors, and with minimal exposure to air will allow your butter to keep for a few days while left out of the refrigerator.

However, the ideal storage for your butter is a cold and dark environment in a sealed container. When kept at about 40F, the butter may be stored for approximately two weeks.

If you’re wanting to buy your butter in bulk, and are wondering how you should store it, you’ll want to consider freezing it.

For example, a freezer held at or below 0 will allow your butter to last about six to nine months if stored in a properly sealed container.

You can tell when your butter has gone bad if you see mold or dark yellow patches. These parts need to be cut off or are an indication that it’s time to throw your butter away.
