    Why Use a Ratio?

    Using a ratio (like 1:16) ensures that your coffee tastes the same every time, regardless of whether you're making one cup or a whole pot.

    Common Brew Ratios

    • 1:15 (Strong): Great for French Press or dark roasts.
    • 1:16 (The Golden Ratio): Ideal for Pour-overs and Drip.
    • 1:17 (Light/Tea-like): Great for highlighting delicate notes in light roasts.
    • 1:2 (Espresso): Concentrated and intense.

    The Math

    If you use 20g of coffee and want a 1:16 ratio:

    • 20g × 16 = 320g of water.

    Key Takeaways

    • Always weigh your coffee and water in grams
    • 1ml of water = 1 gram
    • Adjust the grind size, not just the ratio, for better flavor
