What's actually in this
Kanna is a South African succulent that's been part of social life there for centuries, and it's the only functional ingredient in the can. Ours is Zembrin®, a patented, science-backed kanna extract, standardized at 15mg so every can is the same experience. People reach for it for calm, clarity and social ease, any hour of the day.
Most drinks in this category stack several ingredients and hope something lands. We picked one plant and built everything else around taste: sparkling water, real fruit flavor, and OnoSweet®, a fermented Reb M made from rice, which is how we got to zero sugar without the bitter aftertaste.
- 15mg per can One plant, standardized for a consistent experience.
- Bright, not sleepy The kind of chill that still RSVPs yes.
- Zero caffeine So it fits any hour your day puts it.

Golden hour,
any hourWe stand for calm, clarity, and social ease, and we made the soda that belongs in those scenes: the 5pm porch sit while dinner does its thing, the long table where you're actually in the conversation, the Sunday reset that doesn't need a reason. The can doesn't make the moment, it just never looks out of place in one, and Tuesday's just as good as Saturday.
Tastes like a day on the beach
Sparkling guava, passion fruit and orange. Tropical, refreshing, and like a day on the beach minus the sunburn. It's sweet without the syrup and crisp without the bite, and it finishes clean because we sweeten with OnoSweet®, a fermented Reb M made from rice, so there's no bitter aftertaste waiting at the end of the sip.
Pour it over ice if you're feeling fancy. Drink it straight from the can if you're feeling honest.

It actually tastes good
Most drinks like this taste medicinal at worst and forgettable at best. We tried the other ones, then we got annoyed and made the one people actually crave.
One plant, one job
15mg of kanna, as Zembrin®, our patented, science-backed extract, instead of a kitchen-sink stack. You know exactly what you're drinking and exactly why it's in there.
Sweetened like we mean it
OnoSweet®, a fermented Reb M made from rice, brings the sweetness with zero sugar and zero calories, and none of that bitter aftertaste.
