What does a brew ratio like 1:16 actually specify?+
It's the ratio of coffee grounds weight to water weight, so 1:16 means 16 grams of water for every 1 gram of coffee; a common range for drip coffee runs from about 1:15 (stronger) to 1:17 (weaker).
Why measure by weight instead of using a standard scoop?+
Coffee grounds vary in density by roast level and grind size, so a fixed-volume scoop can hold noticeably different weights of coffee between beans, while a weight-based ratio produces consistent strength regardless of which coffee you're using.
How do I adjust the ratio for a stronger or weaker cup?+
Lower the ratio number (like 1:14) for a stronger, more concentrated cup, or raise it (like 1:18) for a weaker one; small changes matter, since even a difference of 1:15 versus 1:16 is noticeable in cup strength.
Does brew method change the ideal ratio?+
Yes, immersion methods like French press typically use a slightly stronger ratio (around 1:12 to 1:15) than pour-over or drip methods (1:15 to 1:17), since the two methods extract flavor differently and taste balanced at different concentrations.
Why does getting the ratio right matter more than just following a recipe?+
Beans vary in freshness, roast, and origin, so a ratio that tastes balanced with one bag might taste under- or over-extracted with another; treating the ratio as your baseline and adjusting slightly to taste per bag gives more consistent results than following one fixed recipe blindly.
