There is plenty of Oak Aged Vodka about.
http://its-woodka.de/ We discussed this on another forum and there is no definitive answer. Partly due to the fact that any nation can have it's own whisky production regs, ( e.g. in India you can distill molasses and age it in wood and sell it as whisky ). If it is made from 100% grains and distilled in copper stills ( pot or column ) and aged for at least 2 ( as in the USA ) or 3 ( everywhere else ) years then why not. Starka is infused with herbs
after distillation ( iirc ), so probably no, it isn't whisky in anyone's books.
Vodka, it seems, can be made from any ingredient ( grains, potatoes, fruit, molasses ). As far as i can make out what makes vodka vodka is the fact it is distilled many more times than other spirits to a very high abv - neutral spirit.
