I’ll argue until my dying day that you can taste the differences between vodkas, but taste isn’t the initial selling point for most consumers. That’s where marketing comes into play, and the bottle is a big part of that. An interesting look will get people to buy a brand at least once, and then it’s just a question of if the vodka inside is worth getting again.
I’ve only consumed a few of these, but you probably aren’t here for tasting notes. If you are, you can’t do much better than Absolut Elyx and Purity, and you can’t do much worse than Jazz.
If you know of an awesome vodka bottle, drop it in the comments on Facebook. I’ll add it and credit you for your contribution to society.
