What is the perfect coffee to water ratio?

When it comes to the perfect coffee to water ratio, a “Golden Ratio” comes to mind. If such an ideal number exists, this makes it easier to make a perfect cup of coffee each and every time. Unfortunately, things aren’t that simple.

To give you a better idea of different coffee grounds to water ratios, here are some pointers for you:

  • General Ratio
    This refers to most tastes and brewing methods. For this ratio, you can start with values between 1:15 and 1:18. The first ratio gives you a strong coffee with a full flavor while the second ratio gives you something lighter. If you have a more specific taste, use the coffee calculator to determine the perfect ratio for you.
    Generally, though, most people won’t go stronger than a ratio of 1:12. For most brewing methods, this might produce a muddy cup of coffee. For the other end of the spectrum, a ratio lower than 1:20 gives you a bland and watery cup of coffee that’s a bit too bitter.
  • Pour or Drip Over
    This is the most common type of brewing method for a lot of coffee drinkers. This is also known as infusion brewing and you can get this through manual pour-over or auto-drip coffee machines. For this method, you only need a ratio between 1:15 and 1:17 to get you from a bold cup to a standard cup.
  • Immersion
    For this method, you immerse the coffee in the water the whole time, hence the name. This method includes AeroPress and French Press coffee. This method tends to saturate the coffee grounds making it less efficient.
    Usually, people use the immersion method for bold cups of coffee so you can use ratios between 1:15 and 1:12 to get from a standard cup to a strong one.
  • Cold brew
    Although this is also classified as an immersion, it differs slightly because you use cold water. Therefore, you need to make an adjustment to the ratio unless you want to end up with brown water instead of coffee.
    Preparing a cold brew takes more time which means that the grounds get more saturated. So for this method, you can use a coffee to water ratio between 1:5 and 1:8.
  • Espresso
    This is a type of infusion brew which involves pressure. Espresso has less volume but it does offer a bolder flavor. Espresso machines vary so much and this makes it challenging to come up with a single ratio. Generally, you can use a 1:1 ratio for a Ristretto shot and increase this to make the brew lighter.

How much coffee do you put in a French press?

When it comes to the French press brewing method, again, there is no standard ratio. This is because there are different types of French press machines to work with. To make it easier, let’s use the volume of a standard mug as our reference. Most standard mugs hold 12 oz of coffee.

With this value, you can enter all the required amounts into the coffee calculator to find the ideal coffee to water ratio to use. Before doing this, you should also think about the strength you want your coffee to be. The ratio determines the strength of your coffee. When you increase the amount of coffee, this increases the strength. For instance:

  • A ratio of 1:10 in a French press gives you a cup of coffee that’s thick, heavy, and has a bold flavor.
  • Conversely, a ratio of 1:16 in a French press gives you a cup of coffee that’s subtle, light, and has a tea-like flavor.

The strength of your coffee comes down to your own personal taste. There’s no “right or wrong” when it comes to brewing the best possible cup of coffee. In fact, you can even try out different ratios to determine which one works best for you.

How is coffee brewing ratio calculated?

The best way to do this is by using a kitchen scale. But not everyone has such a scale in their kitchens. The next best thing to do is to use volume measurements. The coffee to water ratio is quite easy to understand. For instance, if you have 1 gram of coffee and 1 gram of water, this gives you a ratio of 1:1.

If you want to look at this mathematically, then you can perform a calculation. Let’s have an example to illustrate this. If you want to brew a cup of coffee with a ratio of 1:16, you would need 1 gram of coffee and 16 grams of water.

But if you want to make a cup of coffee with a volume of 350 grams, you should divide the mass of the water by the portion of your desired ratio. Therefore, you can calculate it this way:

350 / 16 = 21.875

Thus, you need 21.875 grams of coffee for your 350 grams of water with a ratio of 1:16.
