Designed to resemble the flavours of Bali, the Gold Coast, Melbourne and Queenstown, the seltzers were crafted by Melbourne company Hop Nation.

Bali flavour invokes rambutan and soursop, Gold Coast was based on coconut, fairy floss, sea salt and Queenstown tastes like mulled wine, cloves and cinnamon.

The special Melbourne brew was based on a deconstructed cafe latte.
