Our engine of adventure, the SF-25 by San Franciscan Roaster Company, is the meticulous machine that brings the flavor to life for Lone Bear Coffee. We chose this American-made beast, built from robust Schedule 40 steel, because its high conductivity and responsive heat controls allow us to achieve extremely precise roast profiles—a critical factor in specialty roasting. While the machine can handle up to 25 pounds, we stick to 10-pound and 20-pound batches. This smaller size gives us the necessary agility to fine-tune the roast, ensuring every single bean develops maximum flavor and guaranteeing ultimate freshness for your roast-to-order adventure fuel.
