Open calculator →Why ratio matters more than the recipe on the bag
Every brewing method — drip, pour-over, French press, espresso, cold brew — comes down to the same two variables: how much coffee, and how much water. Get that ratio right for the method you're using and you're most of the way to a consistent cup, no matter which beans or roast you're brewing.
Each calculator above is built around the ratio range that method actually uses in practice, so you're not stuck converting a drip recipe in your head for a French press or an espresso shot. Pick the tool for your method, plug in your numbers, and brew.
