Water is two-thirds of a bottle of whisky by weight — so why is it not on the label?
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.
