See American style vodka. A boring style of vodka usually made from corn as that is the cheapest thing you can make alcohol out of. Almost all American vodka unless specified otherwise ( and usually sold for a premium) is corn based and usually from Archer Daniel Midland who is the Microsoft of cheep alcohol ( and grain) .Slightly sweet, bland and cheap as dirt.

Can be marked up incredibly by marketing image, there is very little to distinguish one brand from another. Some such as Titolare, redistill it to polish it and make finer cuts then resell it.
