The proof

Why your customers will love it.

Water character your customers already recognise and value. Laboratory testing identifies the finished water’s V.S.O. drinking profile within the Izumi V.S.O. Water Spectrum.

Identify

The finished water is laboratory tested.

After commissioning, a sample of the finished water is sent for laboratory analysis. We then identify its drinking character within the Izumi V.S.O. Water Spectrum, from soft and light through smooth and balanced to fuller-bodied and mineral, and compare it with recognised waters from around the world.

Laboratory testing identifies the drinking character of the water your venue actually serves. It is not selected in advance.

01CommissionThe V.S.O. system is installed and set for your venue’s supply, temperature and carbonation.
02SampleA sample of the finished water is drawn from the tap as it will be served.
03AnalyseHardness, total dissolved solids and pH are measured under laboratory conditions.
04IdentifyThe results identify the finished water’s drinking character within the V.S.O. Water Spectrum and allow it to be compared with the three expected V.S.O. ranges.
The V.S.O. Water Spectrum

Three expected ranges.
Each with a distinct drinking character.

V.S.O. water produced from Australian source waters is expected to fit within one of three drinking-character ranges.

Soft

Yotei Snowmelt

Mount Yotei · Hokkaido

Hardness30–35 mg/L TDS60–80 mg/L pH still6.8–7.2 pH sparkling4.9–5.3

Very soft, light and exceptionally clean.

Inspired by the snow-fed landscape of Mount Yotei, this is the softest and lightest of the three V.S.O. ranges. It has minimal perceived mineral weight and a quiet, almost weightless finish.

Its delicate character is especially well suited to fine food, wine-led dining and customers who prefer water that refreshes without intruding.

Familiar territory

Comparable in drinking style to the softer territory occupied by waters such as Voss, Icelandic Glacial and Antipodes.

Smooth

Fushimi Smooth

Fushimi · Kyoto

Hardness70–90 mg/L TDS130–150 mg/L pH still7.2–7.6 pH sparkling5.3–5.7

Rounded, balanced and broadly appealing.

Inspired by the balanced underground waters associated with Fushimi’s celebrated sake tradition, this range occupies the centre of the V.S.O. Water Spectrum. It has enough mineral presence to give the water body and smoothness while remaining elegant and highly drinkable.

Its balanced drinking character gives it broad appeal across hospitality settings.

Familiar territory

Comparable in drinking style to the smooth territory occupied by waters such as Acqua Panna, Fiji and Santa Vittoria.

Mineral

Rokko Mineral

Rokko–Nada · Hyogo

Hardness190–220 mg/L TDS245–270 mg/L pH still7.5–7.9 pH sparkling5.5–5.9

Crisp, fuller-bodied and distinctly mineral.

Inspired by the more mineralised brewing waters of the Rokko–Nada region, famous for both beer and sake traditions, this range offers a firmer and more distinctive mineral expression.

Its stronger character suits customers who enjoy more presence in the glass and pairs naturally with richer or fuller-flavoured food.

Familiar territory

Comparable in drinking style to the more mineral territory occupied by waters such as Evian and, in sparkling form, the classic European territory associated with S.Pellegrino.

Reading the figures

What the numbers mean.

Hardness — affects feel

Hardness comes mainly from calcium and magnesium. Harder water tends to feel fuller and drier. Softer water feels lighter and gentler.

Minerals — affect taste

Mineral content influences how much flavour the water carries. More minerals usually create a more noticeable taste; fewer minerals create a cleaner, quieter profile.

pH — affects softness and bite

Lower pH tends to taste brighter and sharper. Higher pH generally feels softer. Carbonation lowers pH, which is why sparkling water can have more bite than still water.

Why Izumi is the Champion of Taste

Designed to transform your local supply into a distinctive V.S.O. drinking experience, with its character identified alongside some of the world’s most recognised bottled waters.

The origin

Inspired by Japanese water landscapes and brewing traditions.
Created locally through Izumi V.S.O.

From snow-fed mountain springs to the brewing towns that grew around them, water has long been treated as an ingredient. Izumi brings that thinking to Australian venues.
