How many ounces of water is in each cup?

That’s a great question we get asked all of the time and the answer is, well, a little annoying. Depending on what coffee maker you have, the ounces for each ‘cup’ is different. Thanks a lot coffee maker manufacturers! So when your Mr. coffee, coffee pot says it will make 10 pots of coffee it really means…60 oz of coffee. Or if your Bonavita says it makes 8 cups, it really means 40 oz of coffee. How many ounces of coffee do you typically drink at a time? Most likely, it’s much more than the manufacturers are making their coffee pots today. Sometimes you will get lucky and the coffee manufacturer printed the actual ounces (oz) per cup on the side somewhere. Bonavita and Technivorm are kind of enough to provide these measurements for your conversion.

Ignoring the history of how we got here, let’s just jump in and see a quick chart of how many ounces (oz) per cup of water for the most common coffee makers: Mr. Coffee™, OXO™, Bonavita™, Technivorm™, Bunn™, Hamilton Beach™, Cousinart™, Black & Decker™, Ninja™, Krups™,

We will just conclude by stating that the amount of water per cup does not mean anything in regards to quality. It is merely the reference scale that a coffee manufacturer decided to choose when creating their coffee maker. Also, the measurements of 4.25, 5 or 6 oz are usually recommended by the coffee manufacturers as a good ‘starting point’ they will recommend that you add or subtract coffee per oz to per your desired taste.

  • 8 oz is a cooking measurement
  • 6 oz is typically a US cup of coffee
  • 4.25 oz is typically a European cup of coffee

Ok…if you’re still confused about how many cups per ounce your coffee maker makes, just take the maximum number of ounces and divide by the total number of cups on the coffee pot (or coffee maker). THIS is the number to use for your machine.

Finally, here are the best practices for measuring coffee to brew:

  1. Measure coffee by weight not volume – buy a kitchen scale to measure your coffee by weight and stop using a tablespoon to measure how many ‘heaping’ tablespoons you put in your coffee. Why? It’s because different coffee beans have different densities creating different weights of coffee grounds. Add to the mix that light to dark roasted coffees affect the density and you’ll never really know how much coffee you’re putting in that tablespoon. If you want the same great experience every time you must know how much actual coffee you are brewing. Kitchen scales are cheap and make sure you learn how to sue the ‘tare’ function to measure…it’s very simple.
  2. Start with a 16:1 water to coffee ratio…THEN adjust up or down to your preferred taste – Understanding what ratio of water to coffee you are brewing isn’t just about having ‘strong’ or ‘weak’ coffee, this ratio affects how much you saturated your coffee beans. If you oversaturate your coffee beans you will add unnecessary bitterness, which is typically not desired if you want to enjoy the coffee.

NOW, add to the confusion of the directions from the coffee manufacturers, additional instructions to from the coffee bean roasters….and you have an added complication. We’ll help decrypt that compiled issue in another blog.


Happy brewing 🙂
