Raspberry and rhubarb is a classic tart pairing, and together they make this the sharpest flavour in the Nix & Kix range. The fruitiness is upfront and bright, the rhubarb pulling things in a slightly astringent direction. Cayenne arrives at the end as a low-level spicy undertone that keeps the sourness from dominating. Made with 45% fruit juices (apple, rhubarb and raspberry) and a touch of purple carrot extract for colour. No added sugar or sweeteners, 48 calories per 250ml can. A decent option if you want something that isn't sweet.
