Whether you're a sparkling water aficionado, or just having a hard seltzer moment, this is the bottle for you. That's because it's more than just a bottle: it's an integrated seltzer maker, which means you can whip up and enjoy some bubbly goodness—spiked or otherwise—wherever you're at. Growlerwerks' patented carbonation system maintains fizziness all day, and the bottle's vacuum construction keeps its contents cold for just as long. Just sip or pour from the built-in spout and enjoy.
