Hello Single O coffee-making community! Welcome to our ever-evolving page of brewing methods, O Files and parameters, and ‘Coffee Talk’, our musings on coffee. (No Single O baristas, trainers or roasters were harmed in the production of ‘Coffee Talk’. OK maybe there were a few black eyes but all in all everyone here endorses the sentiments below.) If you’d like any further info, just call us at the roastworks: 02 9693 2232.
