Vodka is defined as a neutral-flavored, clear spirit. At its core, it is supposed to be virtually tasteless, odorless, and clear (like water) in color. But vodka does have very subtle flavors that are distinguishable between brands. Some are peppery, some are creamy, and others have hints of citrus or grain (though it can be hard to pick up on these subtleties even when drinking vodka straight).
