Funky Fluid Free Gelato: Green is the spirulina-coloured entry in Funky Fluid's Free Gelato series, a range of alcohol-free sours from the Warsaw brewery. The spirulina gives it a natural vivid green hue, distinguishing it visually from other entries in the series. Brewed with mango, banana and kiwi, it is one of the more tropical-fruit-focused variants in the Free Gelato line-up.
