Costco Kirkland Signature Margarita Mix Review

An important part of a great margarita is the mix that’s used, it has to be the perfect blend of sweet and sour. The Costco Kirkland Signature Margarita Mix is a convenient way to make the classic cocktail loved by many. Find the best recipe for a lime margarita here using the Costco margarita mix!

Margaritas are my absolute favorite cocktail! I don’t drink often but when I do, it’s usually a margarita. I never used to love margaritas until I was introduced to my Dad’s margaritas using the Costco margarita mix. See the recipe for Ron’s famous margarita below!

If you don’t want to spend any time at all making a margarita you may like the ready-to-drink Costco Kirkland Signature Golden Margarita or the Costco Kirkland Signature Strawberry Margarita. If margaritas aren’t your thing you may like the Costco Kirkland Signature Sangria, Costco Kirkland Signature Vodka 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 555147.


In my opinion, a margarita cannot be too sweet and it needs a strong, refreshing lime taste. The mix has a strong lime flavor and is really refreshing. It’s not overly sweet and doesn’t taste cheap or artificial.

The best margarita I’ve had!

There’s a good balance of sweet and refreshing citrus lime that pairs well with both gold and white tequila. If you’re not a fan of tequila you can definitely pair this with gin, vodka or rum. I use this mix in my Dad’s margarita recipe and I always get complimented on how good my margaritas are.


Two 1.75 liter bottles cost $9.99 Canadian, which isn’t bad at all. This mix is totally worth it in my opinion.

Making a large batch of margaritas for guests can be time-consuming and expensive. This mix scores high on the convenience factor, basically all you do is pour over ice and add tequila (or not) and serve. You can even blend this with ice if you prefer a frozen drink.

When you’re camping or hosting a large party or even a picnic or outing to the lake. Do you really want to be cutting and squeezing fresh limes? If you want a little bit of a more complex tasting margarita, you can use this mix in a recipe as I do.

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 opening. The label suggests drinking the mix within 10 days of opening but my husband and I have used an open one for over a month and suffered no ill consequences.

Serving Suggestions

To make a margarita according to the label you combine 120 milliliters of margarita mix and 45 milliliters of tequila in a shaker with ice. Shake the mix and tequila and serve, very simple!

Just because it’s called margarita mix does not mean you have to make margaritas with it. You can get creative and make various cocktails and mocktails using the mix. I only use the mix to make margaritas and I want to share my 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 Margarita Mix

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


  1. In a cocktail shaker with a bit of ice combine 3 oz tequila, 2 oz Triple Sec or Cointreau, juice of half a lime and 1 1/4 cup Costco Kirkland non-alcoholic margarita mix.
  2. Put a lime wedge and ice in each glass.
  3. Serve contents of shaker over lime and ice. Put a splash of Grand Marnier on the top of each drink.

This recipe can make 2 large drinks or 4 small ones. Let me know if you have any questions or like this recipe!

A 120 ml serving has 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!

Lime juice is the third ingredient after water and sugar. If you’re making your own margarita using just fresh limes, lime juice would be the only ingredient making it a healthier, lower sugar content beverage.

Must buy!

This mix can be hard to find at Costco, so if you see it, grab it! If you love margaritas year-round as much as I do, you might want to stock up when the mix is in stock during the warmer months of the year.

Do you have a favorite cocktail or mocktail recipe that uses this mix?

  1. 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!!

  2. 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.

  3. 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.

  4. 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.

  5. 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…


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



  7. 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!

  8. 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.


  9. 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.

  10. 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,
