Coffee Ratio Calculator
Dial in coffee-to-water ratios for filter brewing, estimate brew water for a target yield, calculate espresso brew ratio, and scale any recipe for any batch size.
Coffee-to-Water, Espresso Ratio and Recipe Scaling
Use grams, ml, ounces or cups. Get fast numbers you can repeat, then adjust your brew based on taste.
For filter brewing, the ratio compares coffee dose to brew water. Brewed yield is usually lower than brew water because grounds retain water. Use absorption to match your method and grinder.
Espresso ratio is beverage yield divided by coffee dose. This is different from filter ratios. Use this tab to set a repeatable target and adjust grind and time for flavor.
Enter what you actually used to recreate a brew. Then change the ratio slightly next time to chase the flavor you want while keeping everything else consistent.
Use the table for fast dialing. If your cup tastes flat, move toward a lower ratio (more coffee). If it tastes too intense, move toward a higher ratio (more water).
