La Colombe Torrefaction Inc

This La Colombe listing at 2620 East Tioga Street in Philadelphia is the company's roasting plant, where the coffee's made before it goes out to their cafés. If you're looking for an espresso bar and La Colombe's draft lattes, head to one of their café locations in the city instead.

The plant has a busy loading dock for wholesale trucks, and on roasting days the smell of coffee carries around the neighborhood. You can buy their coffee and brewing equipment online, and there's a subscription.
