tighe- while mouthfeel has a major factor (and a dramatic one) when sampling vodka, I do believe that they do have a taste quality to them. Perhaps this is that of the alcohol, but it is still a taste nonetheless. I believe that the play between the taste and the mouthfeel make a great vodka. Jason- Ultimat vodka I believe is a blend of differently sourced vodka (potato, wheat, etc...) that results in a unique albeit expensive product. Also, I believe that Hangar One Vodka is made from grape seeds. Ben
