Belvedere is "quadruple distilled from the world's finest rye" and proud of it ... it is the anti-potato vodka!!!!!

Completely agree that the best vodka is made from potatoes; sometimes it can be quite cheap too. For example Monopolowa sold by TJ in the US and made in Austria (by ex-Polish refugees). Completely different mouthfeel and taste compared to the grain vodkas.

But some grain vodkas are quite good, for example Russian Standard. This is because of the grain and water used (winter grains and glacial water with low mineral content). Much better than Gray Goose. Try the Gold Standard (spiked with Ginseng extract).
