But as it turns out, that rumor is not entirely true, although there are similarities between some of the spirits.
Grey Goose itself debunked the claim. USA Today reports that while it's true that the two brands of vodka use water from the same region in France, Grey Goose has a private well.
And even when the same distiller produces both Kirkland and a premium brand — as is the case with Kirkland Signature Añejo Tequila and KAH, which were both produced by Fabrica de Tequilas Finos at one point in time — that doesn't make the products identical, as the process and ingredients likely differ.
