Blue Bottle Coffee's Rich-Ratio Dripper Recipe

Brew 23g of coffee with 350g of water at 93°C using the Blue Bottle Dripper or any cone dripper for a richer 65.7g/L ratio. Bloom followed by steady outward spiral pours, keeping the stream inside the coffee bed and away from the filter walls. Grind within 30 seconds of brewing, ideally using beans roasted within two weeks.
