Citrus Twist Flavor Drops

Don’t sip that sparkling water just yet—you’ll want to add these drops first. Created by the folks behind Aarke, they’ll add a dash of crisp, natural flavor to any drink they meet. (Nine drops is the magic number for a 12-ounce glass.) As for what’s inside? No sugar or artificial sweeteners, that’s what. They’re inspired by craft cocktails, and you’ll be mixing up something great in no time.

1.7 ounce, each one good for up to 10.6 gallons of flavored sparkling water.

• Made in France.
