From the brewery:

Endless, unlimited or without bound. For our 8th birthday we’ve taken the
opportunity to work with some wonderful breweries. With Ophiussa, we’ve created a Smoothie Sour, with over a tonne of fruit puree added to the beer before packaging and pasteurising for a big, silly, thick tropical beer packed with Mango, Guava, Passionfruit & Peach.
