Creative direction / Design / Identity

An independent kombucha brewer based in Shanghai, What A Day knowingly picked a name that can be read in two ways. The idea? Whether it’s a great day or an awful one, this kombucha is there to improve your experience.

The double-disc logo is a simple, straightforward play on the duality of the brand’s name – both tonally and in the doodle-like faces, one happy, one sad. This is combined with a label inspired by the foam netting used to individually package delicate fruits, a hint that this drink contains produce that’s organic, precious and carefully farmed.

Together, the street-style logo, playful art direction and the punchy coloured foam design, look to appeal to a younger generation of consumers.
