this ^ I didn't say you need a better product, or the best product, but you need a great product. If people hear about your product, and they think it's great, then they'll buy it. GG vodka is a great vodka (not a vodka pro but definitely in the high end of consumer vodka I believe), and coupled with their advertising they sell a lot of vodka.

That's anecdotal.

How do you define a great vodka? With blind testing?

If its like beer, then there's a few types of beer and perhaps some spice but its mostly the same.
