DASH infuses sparkling British spring water with extract from cucumbers that don't meet supermarket cosmetic standards - too curved, too stubby, wrong size. It's a decent use of produce that would otherwise go to waste. The cucumber flavour is subtle rather than assertive. There's a clean vegetal freshness on the nose and a light, neutral finish. If you're after something that tastes strongly of cucumber, this won't deliver it. If you want plain sparkling water with just enough character to make it interesting, it fits the brief well. No sugar, no sweeteners, no calories, and B-Corp certified.
