On a good day, a gentle breeze will waft hints of roasting coffee throughout Riverwest, leading your nose to Humboldt Avenue, where Alterra's headquarters, main roasting facility, bakery and one of its cafés are located. While each of Alterra’s cafés has its own unique charm (and Wi-Fi), the owners are committed at all locations to using recycled building materials, eco-friendly business practices and clean, renewable energy sources through their participation in We Energies’ "Energy for Tomorrow" program. These locals prove that a hill of beans can be the foundation of a small empire.
