Dirty soda is the trend that sounds weird and tastes incredible

Okay, so I don’t know who decided to pour coconut cream into a Diet Coke, but whoever it was deserves some kind of award.

Dirty soda is exactly what it sounds like — and also nothing like what it sounds like. It’s not a cocktail. It’s not a smoothie. It’s a regular soda, usually from a fountain, and then someone goes absolutely feral with flavored syrups, cream, fruit, or whatever else is on hand. The result is something that sounds like a mistake and tastes like a revelation.

This is a trend I am fully on board with, and I don’t feel even a little weird about it.

What actually is dirty soda?

Dirty soda is a non-alcoholic drink made by adding flavored syrups, cream — usually coconut cream or half-and-half — and sometimes fruit or other mix-ins to a fountain soda. The base is almost always a Coke, Diet Coke, or Dr Pepper. The “dirty” part just means you messed with it.

Think of it like a fancy coffee drink, except instead of espresso it’s carbonated and instead of oat milk it’s coconut cream poured over ice in a giant cup. It’s chaotic in the best possible way.

Where did dirty soda come from?

Dirty soda has roots in Utah, and honestly that tracks — Utah has a whole independent soda shop culture that the rest of us totally slept on for decades. Soda shops like Swig and Fiiz have been doing this for years, long before TikTok got involved.

Then TikTok got involved. And here we are, the rest of the country finally catching up to something Utah figured out a long time ago. The New York Times covered the Utah soda shop phenomenon back in 2021, and since then it’s been a full sprint to mainstream.

Why does it actually work?

The cream cuts the sharpness of the carbonation. That’s basically the whole secret. If you’ve ever had a cream soda and thought “this is somehow smoother than regular soda,” that’s the same principle. Add a flavored syrup — coconut, raspberry, vanilla, lime — and now you’ve got layers of flavor happening in what used to be a plain Diet Coke.

It’s also just really fun to make. There’s something satisfying about building a drink. You feel like a mixologist. But it’s soda. So the stakes are extremely low.

What are the most popular dirty soda combinations?

The classic is a Diet Coke with coconut syrup and coconut cream over ice. That’s the one that started everything. But people have gotten very creative, and I respect it.

Some combinations worth trying:

• Dirty Dr Pepper — Dr Pepper, coconut cream, a squeeze of lime. This one sounds wrong and is completely right.
• Raspberry Coke — Coke, raspberry syrup, half-and-half. Dessert in a cup.
• Vanilla Diet Coke — Diet Coke, vanilla syrup, a splash of cream. Simple. Hits.
• Peach Sprite — Sprite, peach syrup, coconut milk. Summer in a cup.

The general formula is: base soda + flavored syrup + some kind of cream or milk + optional fruit or topping. Once you get that structure, you can freestyle.

Can you make dirty soda at home?

Yes, and it’s genuinely easy. You don’t need a special machine or a soda shop membership or anything. You need a good flavored syrup, some kind of cream, ice, and a fountain soda — or honestly just a can works in a pinch.

The syrups are the part worth investing in. Torani and Monin both make solid flavored syrups and you can find them pretty much anywhere. In my roundup of the best drink upgrades under $20 I talked about how a single bottle of syrup completely changes your home drink game — this is exactly that situation.

For the cream, coconut cream from a can is the move if you want the full Utah experience. Half-and-half works too. Some people use flavored coffee creamers, which is a little more extra but I get it.

Is dirty soda a lot of sugar?

It can be, yeah — but it doesn’t have to be. If you start with a diet soda base and use sugar-free syrups (Torani makes a whole sugar-free line), you can keep it pretty reasonable. The cream adds some calories but not a shocking amount if you’re not going overboard.

The full-sugar version with regular Coke and sweetened syrups is definitely a treat situation, not an every-Tuesday situation. But what do I know? You’re an adult. Drink your soda.

The case against dirty soda (I’ll be fair about it)

Some people think this is just a trend with no staying power — that we’re dressing up soda to make it seem special and charging four dollars for it at a drive-through. And honestly, that’s not a totally unreasonable position. You are, at the end of the day, adding syrup to a fountain drink.

But I’d push back on that. The soda shop culture in Utah has lasted decades without going anywhere. Swig has been around since 2010. This isn’t a TikTok flash in the pan — TikTok just introduced it to the rest of us. And anything that gets people excited about a non-alcoholic drink option that isn’t just sparkling water with a hint of sadness is fine by me.

Where can you buy dirty soda if you don’t want to make it?

Swig has been expanding outside Utah, so check if there’s one near you. Sodalicious is another chain worth looking at. Beyond the dedicated soda shops, a lot of local drive-through coffee shops have started adding dirty sodas to their menus because the demand is clearly there.

Or — and I can’t stress this enough — you can just make it at home in about three minutes. Once you’ve done it once, you’ll understand why people are obsessed. In my post about trendy drinks that are actually worth the hype, dirty soda came up more than once for a reason.

Dirty soda is one of those trends where the name does it zero favors and the actual thing is genuinely great. It’s fun, it’s customizable, and it costs about two dollars in ingredients if you make it at home.

Give the coconut cream Diet Coke a shot before you decide it’s not for you. Then come back and tell me I was right. I’ll be here, drinking one.
