Join fellow Ottawa home roasters for a hands-on cupping experience built around one shared green coffee from Common Grounds Ottawa. Each participant brings their best roast to the table, then cups side-by-side to explore how different choices shape flavour. Roasters present their approach — equipment, charge temps, roast curves, airflow, goals, and lessons learned — and receive structured, constructive feedback. Taste multiple interpretations of the same coffee, compare techniques across different home setups, and trade practical tips with people roasting just like you. Come learn, share, and deepen your craft through collective experience. Registration is limited. $25 for non-members.
