Get the coffee-to-water ratio right for whatever you're brewing — pour-over, French press, or cold brew. Tell me how much you're making and I'll tell you how much coffee to grind.
Water in grams and milliliters are basically the same for coffee. A kitchen scale gives the most consistent cup — but I've added a tablespoon estimate for when you're brewing by feel.
That's my favorite. I share little life-and-faith notes for the quiet part of the day — want them with your coffee?
For the longest time I blamed my beans, my grinder, anything but the real culprit: my ratio. The single biggest thing that changed my morning cup wasn't fancier coffee, it was paying attention to how much coffee I used relative to how much water. Get that ratio dialed in and even modest beans taste clean and balanced. Ignore it and the best beans in the world come out weak or bitter.
The ratio is just coffee weight to water weight, written like 1:16, meaning one gram of coffee for every 16 grams of water. Once you think in ratios, you can scale a single cup or a full pot without guessing.
The widely cited starting point is the "golden ratio" of roughly 1:15 to 1:17, with 1:16 being the comfortable middle. That works out to about 60 grams of coffee per liter of water, which is where a lot of brewing guidance lands. It's not a law, it's a launchpad. I treat 1:16 as home base and adjust from there.
A simple way to picture it: for one mug of around 350 grams of water, you'd use about 22 grams of coffee at 1:16. For a 500-gram batch, about 31 grams. The math stays the same no matter how much you're making, which is exactly why ratios beat scoops.
Think of the first number as fixed and the second as a dial:
Smaller second number means more coffee per drop of water, so a stronger cup. Larger second number means more water, so a lighter cup. If your coffee tastes harsh or muddy, try adding a little more water (a higher ratio). If it tastes thin and sour, use a little more coffee.
Different methods like different starting ratios because of how long the water and grounds stay in contact:
Cold brew looks like an outlier, but remember you're not drinking it straight. Once you cut that concentrate, it lands in a normal drinking strength.
This is the part that genuinely upgraded my coffee: a small kitchen scale. Scoops measure volume, but beans vary in size, density, and how finely they're ground, so a "scoop" can swing wildly in actual coffee. Weighing in grams gives you the same cup every single day, and it makes hitting a precise ratio effortless.
A scale also makes troubleshooting honest. When you weigh both coffee and water, you can change one thing at a time and actually learn what your taste prefers, instead of chasing a moving target.
For water you can treat them as the same. 1 milliliter of water weighs essentially 1 gram, so 350 ml of water is about 350 grams. That's the quiet convenience of the golden ratio: you can weigh your water right in the brewer or pour to a volume and the numbers line up. Coffee, though, should always be weighed, never measured by volume.
Start at 1:16. For a roughly 350 ml mug, that's about 22 grams of coffee to 350 grams of water. Brew it, taste it, and nudge from there: a couple grams more coffee for strength, a splash more water if it's too intense. Within a few tries you'll find your number.
Once you've got your ratio, the beans and the brewing get to shine. If you want more from-my-kitchen guides like this, check out my other free tools, dial in your ratio, and enjoy a better cup tomorrow morning.
