It’s a modest unpacking (considering how I like to shop for foodstuffs), and the Birra Nursia brews are actually the only Umbrian goods. The rest of the stash was picked up in Tuscany on the way home: zolfino and fagioli verdolini beans (God bless those tuscan mangiafagioli and their variety of beans), packaged soups, and smoked eel (a speciality of Orbetello). I’m no good at suggesting what to bring back from Umbria, but I found a google link that allows you to take a look inside Consorzio Agrario Siena.
This store is the BEST for typical local products from central Italy. Wines, olive oils, chocolate, dried pasta, beans, truffle products, jams, etc. They also have a deli area that dishes out hot meals to go or to eat outside on picnic tables.
The famous Chianina beef from Tuscany is turned into il Chianino: 180 grams of pure ground beef patty, lardo di Colonnata, and pecorino cheese from Pienza. I believe you can order a smaller or larger version of this.
