Tŷ Nant is a Welsh still and sparkling water from a spring in rural Ceredigion, famous worldwide for its striking cobalt-blue glass bottle, a piece of design in its own right. Softly mineral at around 165 mg/L, the water itself is clean and balanced, with a gentle character that suits the table without competing with food. As celebrated for its bottle as for the pour, it has become a fixture of restaurants and design-conscious settings alike. The still offers a smooth, soft drink while the sparkling adds a fine bead — both drawn from a genuine, protected Welsh source.
