How this ratio works
Coffee ratios are expressed by weight: 1 part ground coffee to X parts water. A 1:16 ratio means 1 gram of coffee for every 16 grams (milliliters) of water. This calculator converts between grams, tablespoons, cups, and fluid ounces so you can brew with whatever you have on hand.
Tips for pour over
- Medium-fine grind suits most cone drippers.
- Rinse the paper filter and preheat the dripper before brewing.
- Total brew time of 2:30–3:30 is a good target for 300 ml.
