Coffee seltzer, espresso tonic, carbonated cold brew, iced coffee soda — one of these may sound familiar, or maybe this whole sparkling coffee trend is new to you. What is it? Well, it depends who you talk to, but essentially it’s a mix of some kind of coffee and some kind of sparkling drink, and it’s delicious.
If you’ve ever gone to a high-end coffee shop and had a shot of espresso with a sidecar of sparkling water, that’s likely the inspiration for the coffee seltzer drinks we’ve seen trending right now. While recipes have been floating around on the internet for a couple of years, it seems like the dog days of summer have bubbled up the trend again.
