Believe most of us will have a question in our mind every time when we start to pick up brewing our own cup of coffee. How many water i need to add in to get the perfect taste from this coffee? End up, there will be be a few adjustment going on from cup to cup to get the right taste. So, let’s talk about coffee to water ratio to help you get the answer.

Brew Ratio

Brew ratio is simply known as Coffee to water ratio. The golden ration of the coffee is always depends on your brew type and also your personal preference. Most brewing method are somewhere around 1:15 - 1:18 ratio.

Obviously, 99% of coffee is water. The large number of the ratio will always refer to the amount of water in ml(millilitre). So if someone say the ratio is 1:15 it means 1 gram of coffee to 15 ml of water. An average coffee cup is 8 oz which is 240 ml, if we use the ratio of 1:15 you will need 16 g of coffee to get 240 ml. SCAA come out with the golden ratio of 1:18 which mean you only need 14 g of coffee for a 240 ml cup.

Now, the question is can this apply to all coffee bean? The answer is NO. Those number are just reference as mentioned earlier. You are the one take drink the coffee, you should have it according to your preference. But you can always do a sampling test to find out what your ratio for that particular bean. How to do it ?
