Imagine a standard disposable coffee cup—the kind you get from a gas station or a cheap diner. That little paper cup? It holds exactly nine ounces when filled to the brim. So if you’re making a pour-over at home and someone tells you to use “9 oz of water,” just picture that sad, Styrofoam cup you’d use for a free refill.
Or, think about your reusable water bottle. You know the ones that claim to be “20 oz” or “32 oz”? Nine ounces is roughly half of a standard plastic water bottle (the ones you buy in a 24-pack at the grocery store). So, if you chug half a Deer Park, you’ve just had nine ounces. Congrats. You're a math genius now.
Side note: If you’re still lost, just grab a measuring cup. Pour until the water hits the one-cup line, then add a little extra. Nine ounces is one cup plus two tablespoons. See? Not rocket science. Just water science.
