During the whole brewing and extraction process, the temperature of the hot water in contact with the coffee ground should be maintained at 91 94, which is called the optimal extraction water temperature. A temperature range of 91 94 means that below this temperature range, the coffee will have a more pronounced sour and astringent taste.

Coffee shops that need to make coffee are usually calculated by the gram, and generally 10 grams of coffee beans are needed to make a cup of coffee.

The water temperature for coffee brewing needs to be controlled between 90 and 96, and some professional baristas will use a tamper thermometer to ensure the accuracy of the water temperature. This water temperature ensures that the coffee grounds are fully extracted from their aroma and taste, and that the caffeine concentration does not become too high and cause a bitter taste. Using too low water temperature can easily lead to poor extraction effect and make the coffee too light, while too high water temperature will cause the caffeine to take out too much caffeine, and the taste will become bitter and astringent, affecting the taste of the coffee.

If you're brewing coffee at home, you can let the water cool down a little after boiling before using it. Alternatively, you can try adding some warm water pre-loaded to increase the contact area of the ground coffee with the water, thus increasing the extraction rate of the coffee.

It's worth noting that different kinds of coffee beans require different water temperatures. For example, lightly roasted coffee beans typically require higher water temperatures to help these beans release better aromas and flavors; Dark-roasted beans, on the other hand, require a slightly lower water temperature to prevent excessive bitterness. Slow tung.

In general, the amount of water used to brew coffee depends on the type of coffee grounds, and needs to be kept in the range of 90 to 96. To ensure the extraction and taste, it is best to use a thermometer to adjust the water temperature. <>
