Water Matters

Question

Distilleries argue endlessly about proofing water — the water used to bring a spirit to bottling strength. If water were neutral, nobody would argue. Add four different waters to the same vodka: can you tell them apart?

Hypothesis

Distilled and reverse osmosis water will dilute cleanly, changing intensity but not character. Spring and mineral waters will add something of their own — a texture, a faint taste — and mineral water will be the most detectable.

Materials

• A bottle of Valence Vodka
• Distilled water
• Spring water
• Still mineral water
• Tap water or reverse osmosis water
• 4 small glasses, labeled on the bottom with sticky notes
• A measuring spoon
• Pen and paper

Procedure

1. First, taste the waters alone, at room temperature. Note any differences in flavor or feel. This is your baseline.
2. Pour half an ounce (15 ml) of Valence into each labeled glass.
3. Add 2 teaspoons (10 ml) of a different water to each glass. Stir each gently with a clean spoon.
4. Smell all four, then taste all four, in any order — but pause and reset between samples with a sip of plain water.
5. If you have a helper, have them shuffle the glasses so you taste blind and try to match each sample to its water.

What to Observe

The distilled-water sample should taste like a textbook dilution: same vodka, lower volume. The mineral-water sample often feels different before it tastes different — slightly weightier, sometimes with a faint chalky or saline note on the finish. Tap water results vary wildly by ZIP code; chlorinated tap water can add a detectable off-note. If you can reliably pick the mineral-water glass while blind, the effect is real for you.

The Science

Water is rarely just H2O. Dissolved minerals — calcium, magnesium, bicarbonates — carry their own subtle tastes and change how a liquid feels on the palate. Municipal tap water can add chlorine compounds detectable at remarkably low concentrations. This is why distilleries treat proofing water as an ingredient: at bottling, a spirit at 40% alcohol is more than half water, so the water’s character is fully present in every pour. Valence is proofed with purified water for exactly this reason — dilution should be a controlled variable, not a surprise.

Conclusion

Water is an ingredient with a flavor of its own, and it’s in every drink you’ll ever mix. Choose it the way you’d choose any other ingredient — and remember the result next time you build a vodka soda.
