Whether you’re making a pour-over, French press, or espresso, a consistent grind size is key to achieving great flavor. The grind you choose determines how well (or not) water passes through the grounds and picks up the coffee’s flavor compounds, which in turn affect your drink’s taste, strength, and aroma. Too coarse and you risk under-extraction, which results in a weak beverage; too fine and you risk over-extraction, which results in bitter, sour, or salty flavors.
This Coffee Bean Grind Calculator helps you find the perfect grind for your preferred brewing method. To get started, select the desired quantity of brewed coffee and the amount of ground beans, then click Calculate. This will give you a ratio of how much ground coffee to use per volume of water, with the option to choose imperial or metric units. For reference, 1 tablespoon of ground coffee is roughly 6 grams.
The Ultimate Coffee Bean Grind Calculator: Finding Your Ideal Grind
You can also adjust the ratio based on your preference for strength. Simply move the slider to increase or decrease the number of g of coffee per ml of water. The calculator will automatically calculate the total volume of water needed, accounting for the retention of some water in the waste ground coffee and taking into account your selections for coffee beans and water density.
Keep in mind, as you work with this calculator, that the consistency of your grind can vary from batch to batch. If you open a new bag of beans and the grounds tumble out of your grinder more swiftly or sluggishly, this is the first sign of natural variation in the consistency of your grind. It’s important to recalibrate your grinder with each new batch of beans to ensure a consistent, optimal grind.
