Aquafina is not spring water. Nor is it beer.

Aquafina was quite optimistic when it aired this TV commercial last year. It shows people in a bar and a Bavarian-style beer garden getting positively drunk on the bottled water, as though it were beer. Now, it’s official: Aquafina is not beer. Also, it’s not even spring water. It’s regular old tap water—a fact that PepsiCo will have to make somewhat clearer on Aquafina’s packaging in future. According to the brand’s Web site, the process of purifying Aquafina has seven steps: prefiltration, polishing filter, high-intensity light, reverse osmosis, charcoal filtration, polishing filter (again) and ozonation.
