Reheat: What Makes Some Seltzers Sparkle?

How to judge seltzers, plus the science of carbonation... Over the past decade, seltzer has exploded. Sales have doubled, and companies like Coke and Pepsi are buying up brands and creating their own sparkling waters. So in a crowded field, with a drink that doesn't have much flavor to begin with, how do you tell which one is best? We talk with the hosts of the podcast Seltzer Death Match to find out. Then we nerd out on the science of carbonation: What exactly is it, how does it affect the taste experience, and how do you get the best results from home carbonation systems? Dan Souza, editor-in-chief of Cook's Illustrated, has the answers.
