Craig Robertson wants to make the world a more just place, one beer at a time.
The wrong that he wants to right? The imperfect beer pour.
Consumers may not realize it, he said, but they’re not getting as much beer per glass as they think. Just try pouring out a blonde ale or lager at home. While your pint glass may seem pretty full, it could very well only contain about 12 ounces or so — about 75% of the glass’s volume.
“There’s a ‘Wow!’ moment,” Robertson said. “People realize that the beer that you frequently got, it’s not as much as you expected.”
Robertson, who runs an iPhone development consulting firm called Make Greater LLC, made an app to fix the issue of “beer shorting”: Pour Authority. By measuring out how much beer you get, he said, the smartphone tool can ensure some quality control for consumers who want the beer pour they deserve.
Pour Authority does not use image recognition technology or complex algorithms, said Robertson. Instead, it uses good old-fashioned geometry mixed with user-submitted information.
After selecting a glass type — whether it’s a snifter or a stein or a standard pint — users line up their phone next to their beer. Then, comparing an image on their phone to the actual glass in front of them, they position a slider to align with the beer’s surface. The tool then calculates how full the glass is.
Is it 90 percent full or more? That’s a “perfect pour.” Is it over 80 percent full? That’s “OK.” Anything below that is “low tide.”
Pour Authority also features a map showing bar-to-bar data from all users. The app is in beta right now, but if a significant number of people start using it, the map could eventually show
