I did not “leave anything out”. The argument was that Vodkas “all basically have to be the same by law and you probably can't reliably identify a difference in a double blinded application”. My sole point was that particular assertion wasn’t wholly accurate. The law effectively only applies to the first two parts (heads and hearts). The Vodka origins do not detract from my point at all. Yes many Vodkas have similar origins, but not all of them do, and so they can vary subtly in taste and effects because of the tails which do vary between different Vodkas as noted in the podcast. And yes a cheap Vodka can actually be rated higher from a subjective chemical composition standpoint. But note I never claimed that a “high end vodka” was better. I won’t claim to be one of those people but based on that report I think it’s plausible that some or many people can tell a difference. In short, there is a measurable chemical difference between some Vodkas and some test labs assert that those differences are where differences in taste and effects lie.
