There are an almost overwhelming number of ways to get your coffee fix these days—from good old drip to nitro—but there's one more permutation to add to your caffeine rotation: coffee soda. This refreshing alternative is, essentially, coffee mixed with soda water; a bubbly, iced Americano if you will. And it's the most summer-appropriate way to get your morning buzz.

Baristas are treating these concoctions like mixed drinks and adding everything from bitters to a splash of citrus to create really inventive cups. Sound a bit strange? Don’t knock it until you try it. The citrus and coffee combination has become common in some spots overseas: “In Italy, you can find someone squeezing a lemon into their espresso [and] Australian cafes have been known to create a Sparky [lime with double shot espresso],” says Thi Lam, co-owner of Keepers Coffee Soda—a canned mix of coffee, soda, and citrus that's just about to hit the market Stateside. The combination of citrus and coffee works because "coffee is actually a fruit that can contain hundreds of different flavor notes depending on the region and elevation where they are grown,” says Lam. And adding a splash of lemon, for example, can really magnify more subtle, natural citrus notes in the beans.

“These kinds of drinks seem like a natural evolution for coffee,” says Methodical Coffee’s Co-Owner, Marco Suarez. “Cold sugary drinks like Frappuccinos were a natural evolution from Starbucks’ lattes and coffee sodas seem like a natural evolution for third wave coffee shops who focus on more complex flavors. As for coffee sodas specifically, it’s becoming more common to roast coffees in a way to highlight the bean’s brighter tones and when that’s mixed with the crisp effervescence of a soda, it makes for a super refreshing summer drink.”
