I'm telling you, sour mix is so easy to make at home. It's totally worth the little bit of effort that it takes to whip this up.
I know that it might be tempting to just buy a bottle of pre-made mix from the store. I get it. It's right there, and it's ready to go. But trust me. With how easy AND how much more delicious this is, you'd be a fool to buy some.
There are no weird preservatives and no overabundance of food coloring. Just 3 simple ingredients. You really can't beat it.

💭 What is Homemade Sour Mix?
Sour mix is, at its most basic, a roughly equal mixture of lemon and/or lime juices and simple syrup. It's used to sweeten cocktails (and mocktails).
You've probably seen pre-made bottled sour mix at the liquor store or in a bar. It's bright green in color. This version is nothing like that.
DIY Sour Mix is made with fresh ingredients (just simple syrup and some fresh juices) and tastes SO much better than the pre-made stuff. No weird preservatives or strange ingredients here.
📝 Ingredients
You only need THREE ingredients to make this sweet and sour mix at home.

- Lemon juice: Freshly squeezed, please.
- Lime juice: Again, freshly squeezed.
- Simple syrup: It's so easy to make your own at home. Just follow my recipe!
🔀 Substitutions or variations
- Make it more or less sweet. If you want a sweeter mix, use more simple syrup. Want it more tart? Use less.
- Change the ratio of lemon to lime juice. You can tinker with the amounts of lemon and lime juice if you prefer more of one over the other. Keep the overall amount of juice the same.
👩🏻🍳 How to make Homemade Sour Mix
Just like it says above: this mix is super easy to make. This recipe involves very few, very easy steps. You'll start out by making a simple syrup. We've done this before. It's, well, simple.
Next, you'll squeeze some (okay, a lot of) fresh citrus. Lemons and limes, to be exact. Stir the fresh squeezed juice into the cooled simple syrup and boom. You're done. Stash it in the fridge and break it out whenever you feel like whipping up a cocktail.
If you zest your lemons before juicing them, you can make sous vide limoncello, too!
I've found that the quantity of sour mix made with this recipe fits perfectly in a quart mason jar.

Needed to make a sour mix ASAP since I forgot to get a few family members were coming for Christmas. What better way to celebrate? Drinks! This sour mix recipe went well with the Collins, and daiquiri for starters... more to come. Well balanced on sweetness and sour but still taste the alcohol of choice! 🙂

It's great for both whiskey sours and margaritas...and anything else you make with it. Dilute to make. A lemon-limeade.

We’ve been on a quest to replicate my favorite Martini from a local restaurant. It is called Golden Pear. There are many variations, but I couldn’t find anything on the internet with the exact ingredients mentioned on the menu, so we thought we’d do a little experiment to try to figure it out! The one given was Homemade Sour Mix... I made yours with one slight modification (I used a full cup of lime juice instead of 3/4) and it was fantastic! Thanks!

Hi, Rhonda! So glad you liked it and were able to tinker with the proportions to make it fit your tastes/needs! I'd love to get the recipe for the Golden Pear 😉
Karalee
Great idea and I love my whiskey sour heavy on the fresh squeezed lemon. I unfortunately would have to sub the simple sugar for stevia and I find that stevia does not (for myself) leave any aftertaste when combined with fresh lemon and lime juice.

laurenpacek
I like on the sour side, too! I'm not much of a stevia user, but would be very interested to know how much stevia you would use to replace the amount of simple syrup in this recipe!

Liked the recipe. Perfect for Rita’s

Great recipe! We just had a taste-test with your recipe vs. the store-bought sour mix. Hands down, this one is better. It tastes so fresh and I might not be able to wait until this evening to make a Lemon Drop!

Whiskey to mix ratio?
laurenpacek
I think it depends on your personal tastes, but here's what Food Network has to say about it: https://www.foodnetwork.com/recipes/whiskey-sour-3644825
Holly
About how long will this keep in the fridge?
laurenpacek
Approximately 2-3 weeks. But, if I'm being honest, it doesn't last that long in my house 😉
Holly
I put my sour mix in ice cube trays and then freeze it. Works like a charm. I found the best recipe ever for Whisky Sours; squeeze juice of 2 lemons and 1 orange, 4 Tbls. sugar, 4 jiggers of whiskey, 4 or 5 ice cubes, 1 egg white (best at room temp.) Serves 4 Of course you can switch out regular simple syrup for sugar, adjust sweetness to taste. No sour mix needed!
Tom
While your recipe is great for margaritas, I think it may be a bit sweet for whiskey sours. By using one part lemon juice, one part lime juice, two parts water and one part sugar, the sugar doesn't overpower the taste of the whiskey. This is especially important if you are using a better grade of whiskey vs well grade. Of course, any fresh made sour mix beats the bottled swill you get at the store.
Felicia
Have you ever made it with agave nectar? My husband can no longer have any carbonation and limited sugar. I use agave a lot. I love this using sugar, I was just curious if you’ve tried it with agave.
Lauren Pacek
Never tried it with agave nectar, but it's an interesting idea! If you ever try it, please let me know how it goes!

Hi Tom, and thanks! Definitely feel free to tinker with the proportions to suit your needs. I'm of the same mindset that homemade is definitely better than the bottled store bought crap 😉
James Paulsen
You wouldn't actually use this type of a sour mix for a whiskey sour. This mix is for Mojitos, Margaritas, Tom Collins, etc. Whiskey sours are completely different.
Christopher Scott Nohilly
I normally use lemon juice only in my sour 2 parts and 1 part simple , 1 part water for sour drinks long islands lemon drops john dalys etc....then I make a lime simple equal parts lime and simple to accomodate the margaritas and mojitos cosmos etc.
Wendy
How long is this good for in fridge, also, why not just shake the sugar and water til it dissolves?
laurenpacek
It will keep for a couple of weeks in the fridge. Maybe a little longer. Keep an eye on it, and if you notice anything unusually cloudy, or anything floating in it, it's time to pitch it.
You could try shaking the water and sugar, but it's unlikely to dissolve entirely. Then you're left with a gritty sugar/water mixture. Dissolving it in hot water ensures that the sour mix is completely liquid and that there will be no grit in your drink.
Chase
So just double up the water amount and it worked better for whiskey sour? A girl I'm dating loves Amaretto sour so I'm going to make some sour from scratch. I hate the store bought stuff.
laurenpacek
You can tinker with it however you'd like. For whiskey sours, I almost always just use plain old lemon juice, but this should work, too!
