On tablets above the taps, guests read up on a beer’s honeylike sweetness or spicy notes. They next swipe a tab card and select the beer of their choice. Software tracks how much is poured. Customers pay by the ounce.

“In fact, a lot of people try just two ounces of this and three ounces of that,” Enarson says.

The software also limits drinkers to 32 ounces at a time, so that proprietors can make sure no one is being over-served.
