This is Aqua Libra's take on a berry combination: raspberry and blackcurrant infused into filtered UK sparkling water with natural flavourings and lemon juice. The taste notes describe it as subtle and light, which is probably the honest framing. This isn't a punchy berry drink; it's flavoured water, and the fruit character is present without being particularly bold. Zero calories, zero sugar. If you're looking for something berry-flavoured that doesn't have the sweetness of a cordial or the intensity of a juice, that's exactly what this is.
