What Is a Dirty Soda? The Utah Drink Trend Taking Over America

If you’ve scrolled TikTok lately, you’ve seen it: a cup of pebble ice, a pour of Dr Pepper, a pump of coconut syrup, and a slow swirl of cream. That’s a dirty soda, and Americans can’t get enough of it. People love it because it’s cheap, endlessly customizable, and feels like a treat without being a cocktail. The drink started in Utah, where soda shops grew into a culture of their own among members of the Church of Jesus Christ of Latter-day Saints, who skip coffee, tea and alcohol.

The first shop to turn it into a business was Swig, which opened in St. George, Utah, in 2010, selling soda creations alongside its now-famous sugar cookies. For years it stayed a Utah thing. Then TikTok’s #MomTok crowd and Hulu’s The Secret Lives of Mormon Wives took it national in 2024, and Yelp searches for dirty soda jumped 1,289% in the year after the show premiered. Now it’s on menus from McDonald’s to Toronto coffee bars, and here’s everything worth knowing about it.

What Is a Dirty Soda?

A dirty soda is a regular soft drink mixed with flavored syrup, cream, or fruit. Think of it as a mocktail built on a fountain drink. There’s no alcohol and no coffee in the classic version. “Dirty” just means it’s been dressed up.

What Makes a Soda “Dirty”

• The cream: A splash of half and half, coffee creamer, or coconut cream is what gives dirty soda its cloudy, swirled look and smooth finish.
• The syrup: Coconut is the classic, but vanilla, raspberry, peach, and dozens of others are fair game.
• The fruit: Fresh lime is the most common add-in. Fruit purées show up a lot too.
• The name: It borrows from bar slang, where “dirty” means something extra has been added to a drink.

The Basic Formula: Soda, Syrup, Cream and Fruit

• Base: Dr Pepper, Diet Coke, Sprite, Mountain Dew, and root beer are the most popular. Many shops now also use energy drinks, sweet tea, or sparkling water.
• Flavor: One or two pumps of syrup or a spoonful of fruit purée.
• Creamy finish: A small pour of cream on top, added last so it swirls through.
• Ice: Pebble or crushed ice is the unofficial standard. It chills fast and is half the fun to chew.

Where Did Dirty Soda Come From?

Dirty soda didn’t come out of a test kitchen. It grew out of a community that wanted a fun drink that fit its rules, and a drive-thru shop that gave it one.

Utah’s Soda Shop Culture

• The Word of Wisdom: Members of the Church of Jesus Christ of Latter-day Saints avoid coffee, tea, and alcohol, but soda is allowed.
• A social treat: With bars and coffee shops off the table, the soda run became the go-to way to grab a drink with friends or treat yourself in the afternoon.
• Shops everywhere: Today Utah has the biggest variety of dirty soda shops in the country, with hundreds of drink combos across several chains.

Swig and the Original Dirty Dr Pepper

• 2010 launch: Nicole Tanner opened the first Swig in a small spot across from what’s now Utah Tech University in St. George, charging $1 to get people to try it.
• The inspiration: Tanner loved Sonic’s pebble ice and foam cups and wanted a drive-thru built around custom drinks.
• The name came from staff: The original drink was Dr Pepper with coconut syrup. Employees started calling it a “dirty Dr Pepper,” and the name stuck.
• The trademark: After copycat shops appeared, Swig trademarked “dirty soda” in 2013. The company later said a clerical error meant it was never renewed, so anyone can use the name now.

How TikTok and The Secret Lives of Mormon Wives Took It National

• #MomTok: Utah-based mom influencers made soda runs part of their daily content, and the cups became a recognizable part of the look.
• The Hulu effect: When The Secret Lives of Mormon Wives premiered in 2024, dirty soda was in nearly every episode. Yelp searches for Swig rose 78% in the following year.
• The big chains followed: By 2026, McDonald’s, Dunkin’, Taco Bell, and others had added dirty sodas to their menus.
• Not entirely new: Trend forecasters point out that a creamy soda is basically a cousin of the root beer float, an idea soda fountains have served for over a century.

Dirty Soda vs. Dirty Coffee Drinks

“Dirty” means something completely different depending on where you order. At a soda shop it means cream and syrup. At a coffee shop it means espresso.

What “Dirty” Means at a Soda Shop

At a soda shop, a dirty drink starts with a soft drink and gets flavored syrup, fruit, and a splash of cream. The classic version has no coffee at all. The appeal is sweet, creamy, and fizzy.

What “Dirty” Means at a Coffee Shop

At a coffee shop, “dirty” means a shot of espresso has been added to a drink that doesn’t normally have one. A dirty chai is a chai latte with espresso. A dirty matcha is a matcha latte with espresso. The appeal is an extra caffeine kick and a roasty edge.

Where the Two Meet

The lines are blurring. Dunkin’ now sells a Dirty Soda made with coffee milk and Pepsi. In Toronto, Sam James Coffee Bar launched a Coca-Cold Brew that mixes espresso, Coke, and vanilla syrup. Espresso tonics, which coffee shops have served for years, are basically the grown-up version of the same idea.

Where to Get Dirty Soda

You no longer need to drive to Utah to get a dirty soda. Soda shops are opening across the country, fast-food chains have caught on, and grocery stores carry ready-made versions.

Dedicated Soda Shops

• Swig: The original. It’s in 23 states and expects to hit about 200 locations by the end of 2026.
• FiiZ: Known for customization, with more than 10,000 possible drink combinations.
• Sodalicious: Another Utah favorite that helped grow the soda shop scene.

Fast-Food and Coffee Chains

• McDonald’s: Added crafted dirty sodas to its menu in May 2026, including a Reduced Sugar Dirty Dr Pepper.
• Dunkin’: Its Dirty Soda mixes coffee milk with Pepsi and foam.
• Taco Bell: Rolled out its Dirty Sips nationwide.
• Chick-fil-A: Made its once-secret frosted soda official at the start of 2026.
• Ziggi’s Coffee: One of the first national coffee brands to put dirty sodas on its permanent menu.

• Dr Pepper Creamy Coconut: Back nationwide in 2026.
• Coffee mate x Dr Pepper: A coconut lime creamer designed to pour straight into soda.

Dirty Soda Nutrition: Sugar, Calories and Caffeine

A dirty soda is a treat, and the numbers show it. Most of the sugar comes from the soda itself, and the syrup and cream add more on top. Diet bases and sugar-free syrups cut it down a lot.

McDonald’s lists 230 calories in a large Reduced Sugar Dirty Dr Pepper made with Diet Dr Pepper. A full-sugar version from a soda shop, in a big cup, can easily go well past that.

What’s in a Dirty Soda

Ingredient	Serving	Calories	Sugar	Fat
Dr Pepper	12 oz	150	40 g	0 g
Coke	12 oz	140	39 g	0 g
Mountain Dew	12 oz	170	46 g	0 g
Sprite	12 oz	140	38 g	0 g
Diet Coke	12 oz	0	0 g	0 g
Coconut syrup	1 oz (2 tbsp)	80	19 g	0 g
Half and half	2 tbsp	40	1 g	3.5 g
Flavored coffee creamer	1 tbsp	35	5 g	1.5 g

Caffeine by Base

Base (12 oz)	Caffeine
Mountain Dew	54 mg
Diet Coke	46 mg
Dr Pepper	41 mg
Pepsi	38 mg
Coke	34 mg
Sprite	0 mg
Root beer (most brands)	0 mg

Caffeine by Cup Size (Dr Pepper Base)

Size	Caffeine
16 oz	about 55 mg
24 oz	about 82 mg
32 oz	about 109 mg
44 oz	about 150 mg

For comparison, an 8 oz cup of brewed coffee usually has around 95 mg. A big 32 oz dirty Dr Pepper has about the same caffeine as a cup of coffee, with a lot more sugar.

How to Make a Dirty Soda at Home

A dirty soda takes about two minutes, and you don’t need any special gear. Here’s the classic dirty Dr Pepper, plus a coffee version for anyone who wants their soda with a little extra.

What You’ll Need

• 12 oz Dr Pepper (or Diet Dr Pepper), well chilled
• ½ oz coconut syrup
• ¼ oz fresh lime juice, plus a lime wedge
• 1 to 2 tbsp half and half, coffee creamer, or coconut cream
• Pebble or crushed ice
• A tall glass or a big tumbler

No pebble ice maker? Put regular ice cubes in a zip-top bag, wrap it in a kitchen towel, and give it a few whacks with a rolling pin.

Step-by-Step

1. Fill your glass to the top with pebble or crushed ice.
2. Add the coconut syrup and lime juice to the bottom of the glass.
3. Pour the Dr Pepper in slowly, tilting the glass so it doesn’t foam over.
4. Gently stir once or twice to mix the syrup through.
5. Pour the cream over the top and let it swirl down through the soda.
6. Add the lime wedge and drink it right away while it’s still fizzy.

A Coffee Lover’s Twist: Cold Brew Dirty Soda

This one leans into the coffee-and-cola trend you’ll find at Dunkin’ and specialty coffee bars.

1. Fill a glass with ice and add ½ oz vanilla syrup.
2. Pour in 6 oz cola or sparkling water.
3. Slowly pour 2 oz cold brew concentrate (or a chilled double shot of espresso) over the top.
4. Finish with a splash of cream.

The beans make a real difference here. A medium-dark roast with chocolate and caramel notes pairs beautifully with cola. A bright, fruity coffee, like a washed Ethiopian, works well with sparkling water or lemon-lime soda. If you’re making cold brew at home, you’ll find plenty of options for both on Lovers Coffee.

Tips for Getting It Right

• Keep everything cold: Warm soda goes flat fast and melts the ice.
• Cream goes last: Adding it at the end gives you the signature swirl. Mixing it in early can make some sodas foam or curdle.
• Taste as you go: Start with less syrup. You can always add more.
• Pour coffee slowly: Espresso and carbonation can foam up fast, so add it gently and leave room at the top.
• Make it lighter: Use diet soda, sugar-free syrup, and a splash of oat milk or light cream.

Getting Your Soda a Little Dirty

Dirty soda started as a small Utah treat for people who didn’t drink coffee or alcohol, and it’s now one of the biggest drink trends in America. It’s simple: your favorite soda, a pump of syrup, a squeeze of lime, and a swirl of cream. You can order one at a drive-thru, grab a bottle at the grocery store, or make it at home in two minutes. And if you’re a coffee lover, a splash of cold brew turns it into something that sits happily between a soda and an iced coffee.
