Our Calculators: Precise Ratios for Perfect Coffee
Unlike basic online calculators, The Coffee Calculator tools are built from actual coffee science and expert field testing. Each brewing calculator (covering pour over, espresso, French press, Aeropress, cold brew, Moka pot, and drip coffee) offers precise, evidence-based ratios that adapt to your favorite beans, desired strength, and serving size.
Our calculators go beyond “how much” to brew: they help you troubleshoot sour or bitter results, find your golden ratio for every method, and understand why specific measurements lead to better extraction and flavor. Whether you’re a beginner dialing in your first French press or a home barista seeking espresso perfection, these tools are made to give you confidence and clarity, reducing guesswork and wasted coffee.
