Jyukaku Super Mineral Water
Extremely soft, light and pleasingly smooth, probably owing to its alkalinity (a pH of nine). It is low in minerals, and has no obvious flavour. As a consequence, this brand might seem a bit dull, especially at room temperature. It may work well for brewing coffee or tea, but the high price (this was the most expensive of the five tested) makes it one strictly for aficionados.

Volvic Natural Mineral Water
Named after the town in Auvergne, central France, a volcanic region where the water is sourced, this goes down incredibly well. Even without refrigeration, it is refreshing, with a neutral flavour. With relatively low amounts of calcium and a neutral pH (seven), it is fairly soft and easy to drink. The price makes it even more attractive.
