Caffeine in soda varies wildly by type. Learn which sodas are caffeine-free, how soda caffeine compares to coffee, and how to choose if you're sensitive.
Quick answer
Some sodas contain caffeine and some don't, so the answer depends entirely on the flavor and brand. Colas and pepper-style sodas typically have caffeine, while most root beers, lemonades, and fruit-flavored sodas are caffeine-free. If you're sensitive to caffeine, always check the label rather than assuming based on color or flavor name.
How much caffeine is in a typical soda?
Caffeine in soda usually ranges from about 20 mg to 70 mg per 12-ounce can. Colas tend to sit in the middle of that range, while some citrus or pepper-style sodas land closer to the top. For comparison, a standard 8-ounce cup of coffee has roughly 95 mg, so even a caffeinated soda delivers less than a typical coffee serving. That said, the exact amount varies by brand and recipe, and many sodas contain no caffeine at all.
Which sodas are caffeine-free?
Most root beers, lemonades, and fruit-forward sodas are caffeine-free by default. That's because caffeine is added for flavor in colas and certain pepper-style drinks, not as a universal soda ingredient. If you're building a caffeine-free soda list, start with root beer, lemonade, and any soda labeled 'caffeine-free' on the can. Poppi's Root Beer and Lemonade are both caffeine-free options that fit that list.
Is root beer caffeine free?
Yes, most root beers are caffeine-free. The flavor comes from a blend of roots, bark, and spices like sassafras, wintergreen, and vanilla, none of which naturally contain caffeine. Always double-check the label if you're buying a craft or specialty root beer, since a few brands add caffeine for extra bite. But for the vast majority of root beers, including Poppi's Root Beer, you can expect zero caffeine.
Does lemonade soda have caffeine?
Lemonade soda is almost always caffeine-free. Lemonade itself is just lemon juice, water, and sweetener, so there's no caffeine source unless the manufacturer adds it. Poppi's Lemonade is caffeine-free and has 5g of sugar plus prebiotics, making it a solid pick for sensitive drinkers who still want something crisp and citrusy. If you see a lemonade soda with caffeine, it's the exception, not the rule.
How does soda caffeine compare to coffee?
Soda caffeine compared to coffee is a big gap. A 12-ounce caffeinated soda might have 30-50 mg, while an 8-ounce coffee has about 95 mg and a 12-ounce coffee can exceed 150 mg. So even a caffeinated soda is roughly one-third to one-half the caffeine of a small coffee. If you're cutting back on coffee but still want a little lift, a caffeinated soda can be a step down, but caffeine-free soda is the clearer choice if you're avoiding caffeine entirely.
What should sensitive drinkers look for?
If you're sensitive to caffeine, treat soda like any other caffeine source: read the label every time. Look for the words 'caffeine-free' or 'decaffeinated' and scan the ingredient list for caffeine, guarana, or yerba mate. Caffeine-free sodas like root beer and lemonade are safe bets, but flavors can change, so verify before you drink. Poppi's Soda Staples pack includes a mix of iconic flavors, so check each can's label if you're sharing with someone who's sensitive.
