Brew ratio refers to the relationship between the amount of coffee and the amount of water used to make a cup of coffee. The brew ratio is typically expressed in the form of a ratio, such as 1:15 (coffee to water or c:w), 1:16, or 1:17, etc. It will directly impact the strength, flavour and mouthfeel of the coffee.
A higher brew ratio (more coffee to less water) will result in a stronger, more concentrated cup of coffee with a higher caffeine content, while a lower brew ratio (less coffee to more water) will result in a weaker, more dilute cup of coffee with a lower caffeine content.
For example, a brew ratio of 1:16 means that for every 1 gram of coffee, 16 grams of water is used. A brew ratio of 1:17 means that for every 1 gram of coffee, 17 grams of water is used. The difference in the brew ratio can affect the taste and strength of the coffee.
The brew ratio is often used as a starting point for experimenting with different brewing methods and for adjusting the flavour of the coffee to personal preference. It is also used as a standard reference for comparing different brewing methods, and for evaluating the quality of coffee beans.
The brew ratio is an important aspect of coffee brewing and it is used to achieve a balance between the strength and the flavour of the coffee. It is also a tool used to adjust the taste of the coffee and to achieve consistency in brewing.
Brew ratio is also used to describe the relationship between dry coffee (dose) and amount of coffee extracted (yield). Expressed in terms of dose to yield (d:y)
