A really good vodka should be kept in the freezer to chill it to the point of the fluid being syrupy and then drunk straight up!!
(No, I don’t drink it that often, but it is a sacrilege to dilute good liquor with soda or juice or sweet sticky things)
That's how I feel about single malt scotch (well...at least that's how I remember it). But good vodka taste like smooth rubbing alcohol.
