To make a superb cup of coffee, it is vital to understand the ratios and balances. Water and coffee beans are the only two elements that impact the taste of your brew. Finding the perfect balance between the two is essential to making a great cup of coffee. If you have experimented and failed to find the right ratio, you may wonder how much coffee to use for 30 cups. We will tell you exactly how much coffee to put into your coffee maker for 30 cups.

Different Types Of Coffee Strength

An enthusiast’s first observation regarding a cup of coffee is the proportion of water to coffee. When you taste coffee, you can usually tell what type of coffee you are drinking.

Weak coffee is watery, has minimal flavour, and uses fewer coffee grounds. While weak coffee types are prepared with lots of water, strong types use little water, which results in an unpleasant taste and smell. To create a balanced cup of coffee, water and coffee must be combined in the right way.

How Brew Ratio Works

A brew ratio is a measure of the amount of water to coffee used during coffee brewing. The brew ratio used to prepare your brew also makes a difference in how it tastes, along with the coffee and grind size. 

You can control the quality of your coffee brew using a variety of techniques. Scooping is the simplest method of estimating the amount of ground coffee by counting the number of scoops. The best way to measure coffee and water is with scales because they minimize the possibility of error. Scales help you measure the exact amount of coffee every time you prepare your coffee.

The Golden Ratio As A Brewing Guide

By using the Golden Ratio, which is 16:1, you can measure the amount of water and coffee you need. The general rule is that 16 parts of water must be added to every part of coffee. It is possible to measure the perfect amount of coffee for your coffee maker with a little mathematical understanding. 

Scale For Measuring 30 Cups Of Coffee

We will make 30 cups in this example. In most coffee makers, the liquid content in a cup of coffee is 6 ounces. 30 cups of coffee are equivalent to 180 ounces of coffee liquid. You now have to convert 180 ounces of liquid coffee to millilitres. In liquid measurement, 180 liquid ounces are equivalent to 5328 ml or just over 5 liters of coffee (29.6 ml = oz).

Based on the calculated amount of water, we can figure out how much coffee we need. We use the 16:1 golden ratio between coffee and water to accomplish this. 

To get the water weight in millilitres, simply divide the total by 16. If we divide 5328 ml of water by 16, we get 333 g (1 ml = 1 g). You can brew 30 cups of coffee using this amount of ground coffee.

Using the following equation, you can easily figure out how much water and coffee to mix in a cup of coffee:

  1. Water (oz): (no # of cups) x 6
  2. Coffee (g): (no # of cups) x 6 x 29.57) / 16

Scooping 30 Cups Of Coffee

There’s no standard measurement for the coffee scoop and the coffee cup. One scoop of ground coffee weighs 10 grams, depending on its grind size. Scoop quantities vary according to the quality and fineness of the grind: the finer the grind, the heavier the scoop. A finer grind has smaller particles, so it’s packed tightly in the scoop. There are also differences in size and weight between the scoops.

The calculation becomes much simpler, however, if we assume one scoop is equal to 10 grams of coffee. Each cup should contain one scoop of coffee. For 30 cups of coffee, you will need 30 scoops.

You can verify it with the equation used for the scale method of measuring coffee and water. To make 30 cups of coffee, 333 g of coffee are needed. According to those calculations, we will need 11.1 grams of ground coffee per cup (333 divided by 30). This is roughly the amount of coffee you would scoop because we’re assuming about 10 grams per scoop. 


Whatever approach is used to achieve coffee balance will work. It is important to keep in mind that the amount of coffee you scoop is proportional to the amount of coffee you brew. Having a scale on hand will ensure you’re using the right amount of coffee when making coffee at home. Your coffee will taste better since it will be consistent in taste.
