Think of seltzer as the minimalist of the fizzy world. It’s just carbonated water—plain, simple, and unapologetically naked. No sugar, no minerals, no flavor. It’s like the quiet friend who shows up with nothing but good vibes.
Tonic water, on the other hand, is the drama queen. It’s carbonated water infused with quinine (that bitter stuff from tree bark), plus a hefty dose of sweetener. Spoiler: it has as much sugar as a soda. So if you’re sipping a gin and tonic for “lighter” drinking... well, surprise!
