That might be the question of the moment for travelers passing through two bars at San Diego's International Airport, where beer brewed from jet-bridge air conditioner drips has been turned into two special beers.
Of course, there's a few steps in between the drip and the tap, including purifying the runoff by reverse osmosis and ozone disinfection. The purified water then goes to San Diego's East Village Brewing Company, which turns it into Hoppy Travels IPA and Pre-Flight Pilsner, which are served at Phil's BBQ and Stone Brewing, both in Terminal 2.
Aaron Justus, who runs East Village, told interviewers that “The condensate water is superbly pure and ideal for brewing. Plus, it’s no secret that California is in the midst of a long-term drought, so water reclamation is a creative way to reduce our water footprint here in San Diego.”
The rest of the reclaimed water is used at the airport for cleaning equipment and vehicles, and in the cooling towers that help regulate temperature in the terminal.
