The monks at the monastery in Norcia, Italy, are combining one of the world's oldest monastic traditions with a very 2016 trend: craft beer.

Birra Nursia is a four-year-old, full-scale craft brewery that's staffed entirely by monks. They produce 40,000 bottles of traditional blonde and dark beer per month, and use the profits to improve their 1,500-year-old monastery.
