Discovered in a supermarket in Norway, I picked this one because I initially thought you perhaps pronounced the name TRST in the same way an Irish person might pronounce ‘thirst’. But, it looks like it’s just a stylised anomaly because the actual drink’s name is TØRST (you can see the Ø hidden behind the TRST on the logo). I’m not sure if this is a special edition flavour called Festival Energi Utopia, or if it’s just affiliated with a festival named ‘Utopia’ for promotional reasons, but it’s not really a special flavour. I’m putting this down as a clone as it tastes like a regular own-brand drink. If I had to describe the taste I would say that there are notes of aniseed with a slight tang of burnt caramel. It’s very nice, don’t get me wrong, but it doesn’t have a stand-out unique flavour.
