Natural flavor chemists (yes, that’s a real job) often use green leaf volatiles to make flavors taste “fresh.” Bubly’s Lime flavor contains a tiny amount of hexenal—a compound found in fresh-cut grass. You’re not tasting grass; you’re tasting freshness.

Another wild tidbit: the taste of “cucumber” in seltzer often comes from aldehyde compounds, which are also in cucumber skin and rose petals. That’s why a cucumber Bubly can feel both refreshing and vaguely floral. Mother Nature is full of delightful coincidences.
And here’s the kicker: Bubly’s natural flavors are vegan and gluten-free. No animal products, no wheat derivatives. So that Peach flavor? It’s the essence of a peach, but legally it can’t include actual peach juice (that would change the calorie count). It’s the ghost of a peach.
A Quick Note on “Natural” vs. “Artificial”
Some critics argue that natural flavors are essentially the same as artificial ones in the lab—just sourced from plants instead of petroleum. And there’s a grain of truth there. Both are chemically isolated molecules.
But the key difference is origin. Artificial flavors are synthesized from scratch; natural flavors start with a living thing. For most people, that feels better—even if the science is fuzzy. And Bubly leans into that vibe with its clean packaging and “just water” marketing.
The takeaway? Don’t overthink it. Natural flavors are safe, tasty, and an easy way to drink more water. Your body thanks you either way.
