Q: What is the best water temperature for brewing pour over coffee?
A: The ideal water temperature for brewing pour over coffee is between 190°F and 205°F (88°C to 94°C). This temperature allows for optimal extraction of coffee flavors and ensures a balanced cup.
Q: What is the effect of water temperature on brewing coffee?
A: On the basis of the same grind, filter cup, coffee beans and brewing time, the higher the water temperature, the higher the extraction rate, the less acidity of the coffee will be, and the greater the probability of bitterness. Conversely, the higher the acidity of the coffee, the greater the probability that the flavor will tend to be flat.
Q: What is the difference between circulating water injection and central fixed-point water injection?
A: Under the premise that the rest of the conditions remain the same, the injection of water in the circle will increase the extraction rate of the coffee, just like using a stirring rod to help the substance dissolve in the chemical reaction, the faster the circle is made, the more substances in the coffee bean will be dissolved in the water, and the overdoing will make the whole cup of coffee sweeter than sour and even more bitter. However, the central fixed point water injection will not increase the extraction rate of the coffee, so less substances in the coffee beans will be dissolved in the water, and the flavor will tend to be more acidic than sweet, and it is more likely to appear bland like flavor.
Q: What effect does the grind have on the flavor of the coffee?
A: Under the condition that the rest of the conditions remain the same, and within the reasonable grind range of pour-over coffee, the coarser the grind will make the contact area between the coffee beans and the water smaller, so that less flavor substances are dissolved in the water, and the flavor of the coffee will become more sour than sweet or even bland like a glass of water. The finer the grind, the larger the contact area between the coffee bean and the water, so that more flavor substances are dissolved in the water, and the flavor of the coffee will become sweeter than sour, and even more bitter will appear.
Q: If you want to adjust a cup of coffee, which variables such as grind, water temperature, filter cup, and brewing time are more recommended??
A: The temperature change is very inconvenient to control, so it is more recommended to adjust the flavor of a cup of coffee from the grind, powder-to-water ratio, and filter cup.
