Indian Made Foreign Liquor is the category that dominates the world's largest whisky market, and its standard recipe begins by cutting 96% neutral spirit down to 42.8% with demineralised water. That single step makes water the largest ingredient in the bottle by volume — and, because an ENA base carries almost no congeners to hide behind, the one with the least cover for a fault.

Almost every tasting note treats "body" as though it were thickness, and almost every drinker who waters a cask-strength malt reports that it thins out. Both are misreadings of what is happening. Whisky is barely more viscous than water at any drinking strength, and the texture that disappears when you dilute is not viscosity at all — it is a heat receptor letting go, a class of esters coming out of solution, and, if you poured the wrong water, a mouthfeel the water brought with it.

Peat smoke reaches the glass as a family of phenolic molecules, and guaiacol — the marker compound for smoky character — happens to be the exact molecule the landmark whisky-dilution study modelled. Below roughly 45% ABV it sits at the liquid–air surface rather than in the bulk, which is where your nose meets it. That makes a peated dram the best-supported case of water 'opening up' a whisky, and it also makes the water you add the one that can least afford chlorine.

The largest single ingredient in a bottle of whisky is water that somebody poured in deliberately, and on almost every label in the world it is invisible. That is not an oversight — it is a written exemption in EU law, a gap in the US mandatory-label list, and a compliance question India answers differently from either. Here is exactly what the rules require, what they leave out, and why the invisibility makes the specification a producer's own problem rather than a regulator's.

Demineralisation strips a water of everything measurable except the thing forensic laboratories actually read. The hydrogen and oxygen atoms in a water molecule carry a signature of the rainfall that produced them, and in a bottle at 40% ABV those molecules account for most of the oxygen in the liquid. Counterfeit Scotch has been identified on exactly that basis — which makes the blending water a matter of brand protection as well as flavour.

A blend is not poured together on the way to the bottle. Casks are vatted, the vatting is brought close to strength with demineralised water, the whisky is left for months to marry, and a final cut sets the label figure. Water enters that sequence twice, and by volume it is the largest single thing a blender adds.
