Water Sommelier Guide: How to Taste a Spring

Just as a wine sommelier studies acidity, tannins and body, the water sommelier analyzes pH, mineralization and texture. So-called "water sommelier" is not a passing fad: it is the natural consequence of a gastronomic culture that values every element on the table.

Why does water deserve a ritual?

Each spring water has a unique personality. The mineral composition of the soil, the filtration time, the geology of the bedrock: all these factors imprint a distinctive character on the water that emerges. What makes Fluvian particularly interesting for sommelier is its exceptional balance.

With a pH of 7.6, Fluvian is slightly alkaline, giving it a roundness on the palate that even trained palates do not expect to find in water. Its total dissolved solids (TDS) of just 42 mg/L classify it as very low mineralization — meaning it does not compete with flavors, but accompanies them.

“The best water is the one you don't notice. Exceptional spring water is felt.“

Temperature: The best kept secret

The most common mistake in water tasting is serving it too cold. Below 8°C, taste buds become numb and it is impossible to appreciate the subtleties of the mineral profile. The ideal temperature for tasting a premium spring water is between 11°C and 13°C.

At this temperature, the water reveals its texture —Fluvian's natural silica (18 mg/L) produces a characteristic silky sensation— and allows the most delicate mineral notes to express themselves. It is the same temperature at which the finest white wines are served, and for the same reason.

Glassware: More than aesthetics

The ideal glass for sommelier water has a long stem and a medium bowl. The stem prevents hand heat from transferring to the water. The medium bowl allows just enough oxygenation to release the water's more volatile aromas — yes, water also has aromas.

The glass should be fine and lead-free. Absolute transparency is not a visual luxury: it is a tasting tool. Spring water should be observed: its clarity, its brilliance, the way light refracts through it. Cloudy water or water with visible sediment is a warning sign.

Pairing: Water as a bridge between flavors

The basic principle of water pairing is that it should not compete with flavors, but cleanse the palate and prepare it for the next bite.

Fresh Oysters & Seafood: A slightly alkaline water like Fluvian contrasts with the salinity of the sea, leaving a clean finish that invites repetition.

Goat or Aged Cheeses: It cleanses lactic creaminess from the palate, preparing the mouth for the next bite or glass of wine.

White & Raw Fish: Low mineralization respects the delicate flavors of sashimi or ceviche without saturating the palate.

How to read a water label

Every water sommelier should know three key data points on the label: pH (ideal between 6.5 and 8.0), TDS (between 20 and 200 mg/L for premium table waters), and silica (over 10 mg/L for a silky texture). At Fluvian, these three numbers tell the story of water filtered by forests and volcanoes.
