Seltzer? I hardly know her!
Let’s start with seltzer, the Basic B of the bubble crew. Nothing extra to speak of here, just plain old water injected with a hearty blast of carbon dioxide. That means making an OG Canada Dry is as easy (and probably as satisfying) as using a SodaStream. And because they’re unadulterated and flavorless by definition, seltzer is what you’re most likely to find as the basis for all your favorite fruit-tinged crushers like Spindrift, Polar, Bubly, Canada Dry, and yes, LaCroix.
The term seltzer can be used interchangeably with sparkling water, fizzy water, bubbly water, and soda water, thanks to its plain jane makeup. Contrary to its modern-day genericism, though, seltzer’s name was actually coined by an 18th-century German beverage company famous for selling naturally carbonated mineral water sourced from Selters spring in Niederselters. Go figure.
