Experts from the Department of Food Science at the University of California recently tested 18 beers in an attempt to define what properties made the beers “thirst quenching.”
After exhaustive tests, the scientists reached a shocking conclusion–beer is not really thirst-quenching at all. The only potential “quenching” attributes they could identify in the beers were
the varying degrees of carbonation and bubble density.
All the other factors that give beer its character–foam, color, flavor and aroma–were found to actually reduce beer’s ability to relieve thirst.
