Costco Kirkland Signature Margarita Mix Review

Margaritas are the drink of choice in our house, and Costco’s Kirkland Signature Margarita Cocktail Mix has been our margarita mix of choice for years! Earlier this year, we were surprised and a bit worried when we noticed that Costco had changed our favorite margarita mix. Apparently it’s organic now as the name was changed to Kirkland Signature Organic Margarita Cocktail Mix. Is this new margarita mix as good as the old one? What’s the best recipe to get the perfect margarita out of it? Read on to find out!

If you don’t want to spend any time at all making your margaritas, you might prefer Costco’s ready-to-drink options like the Kirkland Signature Golden Margarita or the Kirkland Signature Strawberry Margarita. If margaritas aren’t your thing, you might want to check out the Kirkland Signature Sangria, Kirkland Signature Vodka, Kirkland Signature London Dry Gin, Kirkland Signature Irish Cream, Mamamango Moscato, Kirkland Signature Spiced Rum or the Costco Kirkland Signature Frozen Cocktails.

Location in Store

You can find the margarita mix in the main Costco store (not in the liquor store), near all the other beverages on the side of the store. The item number is 5555147.


I’ll get this out of the way right now. In my opinion, this new Organic Margarita Mix isn’t as good as the old Margarita Mix. It’s not bad, but it’s less sweet, more tart and tastes more like limeade than margarita mix. A good margarita can’t be too sweet and it needs a strong, refreshing lime taste, which this mix has, but it’s just not quite hitting all the right notes like the old one did.

The best margarita I’ve had!

The Organic Margarita Mix definitely doesn’t taste artificial or too sweet, and it is refreshing. The strong citrus lime flavor pairs well with either gold or silver tequila. If you’re not a fan of tequila, you can also pair this mix with gin, vodka or rum cocktails or even dilute it and drink it as a limeade.

Ready to drink!

I’ve always used the original non-organic Kirkland Margarita Mix in my Dad’s famous margarita recipe (which I’ve included below) and I always get complimented on how good my margaritas are. I’m hopeful I’ll still get compliments on the ones I make with the new Organic Margarita Mix, but I’m not feeling as confident in them.

The price for the Organic Mix is $11.99 Canadian for a pack of two 1.75-liter bottles. That’s pretty cheap considering the number of margaritas you can get out of these two big bottles, but not as cheap as before! Organic foods always cost more, so I’m not too surprised by this.

The mix comes in a two-pack. Each bottle is 1.75 liters.

Back in 2022, a pack of two 1.75 liter bottles of the original Costco Margarita Mix cost $9.99 Canadian. At least Costco hasn’t made the bottles any smaller!

Making a large batch of margaritas for guests can be time-consuming and expensive. Heck, even a single margarita is a lot of work if you make it from scratch! For that reason, this mix scores high on the convenience factor. Basically all you need to do is pour it over ice, add tequila (or not) and serve. You can blend the mix with ice if you prefer a frozen drink. You can also use the mix as the base for a more premium margarita, which is how I use it.

Once opened the mix should be consumed within ten days.

The best-before date listed on the bottle is about a year from when I purchased the mix and it needs to be refrigerated after you open the bottle. This hasn’t changed from the old non-organic mix. The label suggests drinking the mix within 10 days of opening, but my husband and I have used an open one far beyond that and haven’t suffered any ill consequences. To be clear, I’m talking far, far beyond 10 days. Like months. But you didn’t hear that from me!

Serving Suggestions

There’s a simple margarita recipe on the bottle of Organic Margarita Mix. According to the label, you combine 125 milliliters of margarita mix and 45 milliliters of tequila in a shaker with ice, shake the mix and tequila and serve – very quick and easy!

Of course, just because it’s called margarita mix doesn’t mean that you have to make margaritas with it. I’m sure you can get creative and make all sorts of lime-based cocktails and mocktails using the mix.

Personally, my favorite way to use the old mix and the new one is as the base for a fancier margarita. Basically I use the mix to cut down on the number of fresh limes I need and avoid having to worry about using sugar or syrup. Here’s my favorite receipe, which is actually my Dad’s recipe!


3 oz. tequila (the Kirkland Signature Silver Tequila is my personal favorite, but the Kirkland Signature Anejo Tequila works too!)

2 oz. Triple Sec or Cointreau

1 slice of lime placed in each glass

Half of a lime squeezed (so juice from half a lime)

1 and 1/4 cup Kirkland Signature Organic Margarita Cocktail Mix

1 splash of Grand Marnier on top of each drink (optional, but my Dad wants you know this creates a “Cadillac” margarita!)


  1. In a cocktail shaker, combine 3 oz. of tequila, 2 oz. of Triple Sec or Cointreau, the juice from half a lime and 1 1/4 cups of Costco Kirkland Signature Organic Margarita Cocktail Mix. You can add a bit of ice if you like, but it’s not necessary.
  2. Put ice in each glass and add a lime wedge.
  3. Pour the contents of the cocktail shaker over the lime and ice. Add a splash of Grand Marnier on the top of each drink.

This recipe can make two large drinks or four small ones. Please let me know if you have any questions and give me your feedback on the recipe!

The new Organic Margarita Mix has fewer calories and carbohydrates and less sugar than the old mix. A 125-milliliter serving contains 70 calories, zero grams of fat, zero grams of fibre, 19 grams of carbohydrates, 18 grams of sugar, zero grams of protein and 65 milligrams of sodium. No wonder it tastes less sweet and more tart!

A 120 ml serving of the old mix contains 100 calories, zero grams of fat, fiber and protein, 26 grams of carbohydrates, 45 milligrams of sodium and 25 grams of sugar. That’s a lot of sugar in only half a cup!

The old mix has a few more ingredients than the new organic mix. The organic mix is definitely a bit more natural, which I like. I’m torn. I appreciate that Costco is trying to introduce natural and organic products, but I miss the flavor of the old mix!

Give it a try!

This new Costco Organic Margarita Mix isn’t bad. I’m still using it to make my margaritas and I’m still enjoying them, just not as much as I did with the old mix! Part of me wants to like the new mix better because it’s less artificial with less sugar, but I don’t drink margaritas for my health!

  1. Member’s Mark Margarita Mix.

    I get it, it’s not Kirkland, but honestly their new margarita mix is REALLY good and tastes identical if not better to Kirkland’s old Margarita mix. This new Organic one, while I commend them for trying organic, who really is considering Organic when consuming alcohol? If they are going to maintain Organic, they need to reformulate. Organic can be great, but they missed the mark on this one.

  2. I am also devastated that they took the old mix away! I have 4 adult kids who come visit us and ALWAYS request a batch of my famous margaritas. I had to use a different mix and they all instantly noticed and asked what happened. Please bring it back, Costco!! I have tried 8 different kinds of mix and none compare.

  3. Very very very angry that Costco is messing with the Margarita mix!!!’ I’m in Arvada CO, near Denver, where neither the old nor the new mix is available. I used to find it on Amazon but it is not available there anymore either 😡 I am thinking that perhaps Costco wants to make us buy their pre mixed margaritas with the alcohol already in it. I plan to boycott that product and am curious to know what brand others have found to be similar to the original mix???? Thanking everyone in advance.

  4. As someone who had bought the original Kirkland Premium Margarita cocktail mix since the first time I saw it Costco, I am very upset that they stopped making it. The Organic is pure dreck by comparison.

    Now I have to find another mix that comes close. Ls Paz comes to mind, but it’s not easy to find any more either.

  5. I tried the new Kirkland Organic Margarita mix a couple days ago and found it to be horrible! My husband and I had to pour our drinks down the drain. It tasted like citrus rind, very bitter and the after taste was worse. I brought the mix back to Costco for a refund and expressed my disappointment. The original Kirkland Margarita Mix was delicious. Wish Costco would bring it back!!

    • Their hotdogs are the best and they haven’t canceled them. Why take a great tasting margarita mix and cancel it? Obviously people want it back. The customer should get what they want. At least tell us who makes it so we can get it there

    • Totally agree. We have several bottles of the new Organic and it is ‘fizzy’ and the bottle swells up with some chemical reaction. My wife won’t drink it at all.

  6. After over a year I found Kirkland’s Organic Margarita Mix at my Costco. What a disappointment! It is not at all like the original margarita mix. Even with added triple sec it has a bitter aftertaste. Definitely the last bottles I’ll buy. You screwed up a good thing royally. Bring back the original.

  7. Please do a review soon on the new Organic Kirkland Margarita Mix. I was not aware that Costco was discontinuing the former excellent margarita mix that many loved or I would have stocked up.
    I was so excited when I saw the 2 bottle margarita mix finally in my Costco. I tried it this evening and it is horrid and I’m not exaggerating. The closest I can describe it is it tastes like what I would think bug spray would taste like. It ruined my dinner. Somehow Costco needs to be made aware how terrible it is and replace it with the old formula.

  8. How about stocking it in Hawaii! First you were out of the silver tequila, then when it is back in stock you do not have the margarita mix.

  9. I just got a message back from Costco, returning in the spring of 23; just in time!!

    Add a splash of Parrots Bay 90 for a Caribbean flare… plus a little kick…


  10. We’re still looking for Kirkland Margarita Mix in Seattle. We’re also missing Kinder Teriyaki Sauce. Please bring them both back!



  11. Haven’t been able to find the Kirkland Premium Margarita Mix.
    None of the Austin stores have it. The mixes with wine? Really is not a Margarita!

  12. Hi Natalie, another great review.

    But let me just say this: I think you meant to add 45 ml and not 45 litres of tequila to the standard mix. If you meant 45 litres, I’d like an invite to your next get together, please. It just might be worth the drive from Montreal.


  13. Why would you stop carrying a great product! Come on get the Kirkland margarita cocktail mix back!
    Who ever made the decision to stop carrying it, needs a come to Jesus meetings!

    • It’s been unavailable here in Anchorage Alaska since early last summer😳 It was always available in the Liquor Store of Costco but now some people are saying it’s stocked in the main part of Costco with side drinks!

        • Natalie,
          I have looked everywhere in the South Bay in Los Angeles & have not been able to find anywhere that has the 2 bottle Kirkland Margarita mix in stock. Can you tell me which store to go to purchase some? Your help would be greatly appreciated….


          • Hey Mitch! I write this as I’m currently drinking a margarita using the mix. Apparently it’s being discontinued but I’ve found some on and off at my Costco. Not all the time though. I hope they always have it as it’s one of my favorite products.

    • Hi Gene! I actually got some on June 17 at my Costco. I bought six containers. I hope that it’s not discontinued.

  14. Let me start buy saying I have been going to Costco and have been a member since it opened. Love my Costco!
    I absolutely love the Kirkland Signature Margarita Cocktail Mix! I was very upset when I went to my warehouse and found there was no more. 🙁 I was told you would no longer be carrying this item. Please say it isn’t true!!
    I was also disappointed when you stopped carrying Dove Intensive care shampoo & conditioner.
    I was then looking for Golds cocktail sauce and was told you only carry it around in Nov & Dec for the holidays. Do you know how many people eat shrimp cocktail in the summer? A lot. Please put these items back on you shelves in Milford, Ct.. It would make me and so many others so happy.
    Thank you,
