What’s the Golden Coffee to Water Ratio?

Have you heard about the Golden Cup Standard? This coffee to water ratio was formulated by a professor in MIT in 1950. This ratio of brewing methods was based on a survey of many coffee drinkers.

This standard tells us to mix 55 grams of coffee grounds mixed with one liter of water. The resulting coffee to water ratio is 1:18. One part ground coffee to 18 parts of water.

The Golden Cup Standard is supported by the Specialty Coffee Association (SCA). There is a 10 percent allowance for the ratio. This standard talks more of the coffee brewing process rather than the ratio.

The coffee strength is expressed in Total Dissolved Solids. The expected strength of your hot or cold brew coffee is 11.5 to 13.5 grams of dissolved bean coffee.

Setbacks of the Golden Cup Standard

There are certain setbacks of the Golden Cup Standard. Some people don’t mind it while others do. Let’s know some of them below:

  • Not all people will have the tools and time to compute the Total Dissolved Solids (TDS). That will be inconvenient for most coffee drinkers.
  • The 1:18 coffee to water ratio is too thin, especially for low quality ground coffee or coffee beans. You need to have a thicker outcome after the brew method.
  • The Golden Cup Standard doesn’t consider adding milk to your perfect coffee. Some people like to have milk with their coffee at home.
  • You can use this coffee to water ratio through any brew methods. Whether you will have French press, drip coffee, or automatic drip, this standard is workable for all.

To minimize its setbacks, having a solid experience in the brewing methods is essential.

What are examples of the Golden Cup Standard?

The best coffee will depend on your personal preference. People will have different tastes in their cup of coffee. Some like it strong while some like it smooth with milk. Personal taste will be the standard reference for getting the right balance for your coffee at home.

We’re done talking about what the Golden Cup Standard is, right? Just to recall, that will be around two tablespoons of coffee dissolved in six ounces of cold or hot water.

If this is too thin for you, you can make it a bit stronger by adding more coffee to the same water volume. Otherwise, you can retain the same coffee and reduce your water.

Now, let’s give some more detailed examples of this 1:18 ratio.

  • 13.1 grams of coffee to 8 oz water – good for 1 cup
  • 16 grams of coffee to 8 oz water – good for 1 cup
  • 26.2 grams of coffee to 16 oz water – good for 2 cups

The taste of your final cup will depend on your ratio and the quality of coffee beans you are using. The golden ratio stands on its reputation as the main reference for everyone.

Regular Coffee

Regular coffee is made by pouring hot water to your cup of coffee beans. Allow it to brew for a few minutes until almost all of the beans are dissolved. The coffee to water ratio for this is 66 grams per liter of water or 1:15. You can mix milk with this ratio and still get a good taste.

French Press Coffee

This is a manually made coffee. You will need to use a plunger, a cylinder-shaped carafe, and an integrated coffee filter. A French press allows you to get a full-body taste of your whole bean coffee. The coffee water ratio for this is 71 grams to one liter of water or 1:14.

Drip Coffee or Pour Over

This is one of the most popular ways of brewing your coffee. You will need a drip coffee machine for this simple process. The hot water will be pushed towards the ground beans where it is allowed to brew and drip into the carafe. You will need to have a filter for your drip coffee.

The usual coffee water ratio for drip coffee is 1:17. If you want a stronger taste, then make it 1:15. Both ratios will result in a quality cup of great coffee.

The common coffee to water ratio for immersion coffee is 1:17. If you want a stronger taste, that can be 1:15 or 1:14. Below are more examples for the different ratios:

  • Regular: 13.90 grams of coffee for 8 ounces of water to make one serving
  • Strong: 21.50 grams of coffee for 8 ounces of water to make one serving
  • Regular: 27.8 grams of coffee for 16 ounces of water to make 2 servings
  • Strong: 42.90 grams of coffee for 16 ounces of water to make 2 servings

Cold Brew Coffee Ratio

If you like to have a cold drink, you will also need to know about the right cold brew coffee ratio. For this one, it follows the 1:8 ratio. The main difference is that you have to brew it overnight to extract more flavor.
