That's a bit too simplistic!
Vodka can be made from wheat, rye, beets, corn, potatoes, barley, grapes. sugar cane, hemp seeds and rye, among others.
The grain-based ones tend to be smoother and can be a bit fruity; the vegetable-based ones tend to be slightly oily and more herbal (bad ones can taste overly medicinal).
There are very good wheat vodkas and very bad potato vodkas.
So, if you're a coeliac and want a good vodka, what should try? Chopin. It's a Polish potato vodka, made from organic potatoes and very smooth with a slight oiliness. It's a very clean vodka that's fantastic with blinis and black bread.
I've managed to wangle it as a present a couple of times, and if I had money to burn it's one drink I'd definitely spend my own money on. And do not mix it with anything!
