Vodka is mostly water, so the type of water used is a huge deal. Grey Goose uses natural spring water from the Cognac region (yes, the same famous region for cognac). This water is naturally filtered through limestone, which gives it a pure, crisp profile.
Imagine you’re making iced tea. If you use tap water with a weird taste, your tea will taste weird too. But if you use crystal-clear spring water, every sip is refreshing. That’s exactly what they’re going for—no funky minerals competing with the vodka’s flavor.
