Ratio of coffee powder to water-

Would you like an espresso or a weak coffee?

Ratio is defined as a relationship between two groups or numbers that represents how much larger one is than the other. So, in our context, how much coffee you should use relative to water. Normally, when using 15 grams of coffee powder, we use 240 grams of water to extract coffee.

The powder-to-water ratio naturally refers to the ratio of coffee powder used to injected water, not to the amount of coffee liquid extracted.

In this ratio of powder to water, the brewed coffee basically does not go wrong, has a high sense of balance, and can also taste the unique flavor characteristics of the coffee. What happens if you use different proportions?

Let's use the 1:14 ratio-change the amount of water to 210g with the same amount of 15 grams of coffee powder. Extracting the same amount of coffee with less water will make the coffee liquid thicker, while other parameters and brewing techniques remain the same; on the other hand, if you use the ratio of 1:18 (15g / 270g), you will taste milder, but lighter coffee with lighter flavor and lighter Body, which will have a different flavor.

When setting specific coffee extraction parameters, you only need to test different powder-to-water ratios with the same grinding settings to find the perfect ratio more quickly.

Remember to have a precise name, or it may cause the proportion to be out of proportion.

Extraction time determines grinding scale

As mentioned above, the extraction time of coffee determines the grinding size of coffee particles. Sometimes, the extraction time tells you how fine or coarse grinding should be used. If you need to use a short coffee time (such as espresso), your grinding size should be very fine so that water can extract all the high-quality coffee ingredients from the coffee.

On the other hand, if your extraction method / equipment takes longer (such as a French kettle), you should grind the coffee powder so that you don't extract too much of the coffee, so that you can extract the substances that are not well grown in the coffee.

The temperature at which coffee is brewed

The temperature of the water is often forgotten, but it is crucial when making coffee. If you brew coffee at too high a temperature, you will be in danger of extracting coffee, making your coffee taste bitter. On the other hand, too cold water may make your coffee plain and sour.

In general, deep-roasted coffee prefers a lower temperature because they may have too much bitterness in the coffee liquid extracted at high temperatures. On the other hand, lighter roasted coffee beans need more water power to extract good substances because of their higher density. And in the extraction of coffee, the higher the water temperature, the sweeter the coffee; on the contrary, the lower the water temperature, the brighter the flavor and the stronger the acidity.
