The relationship between water temperature and coffee, what is the different taste of brewing coffee at different temperatures?

For information, please pay attention to Cafe Workshop (Weixin Official Accounts cafe_style)

How does too high or too low a temperature of the water used to extract coffee affect coffee flavor? Have tried to taste a coffee, coffee is newly opened, freshness can be guaranteed, but I do not know why the aroma, alcohol, acidity are almost not felt, preliminary guess is the reason for the high water temperature, but can not be determined, about the impact of water temperature on coffee flavor, want to know more detailed.

This is not a problem that temperature can solve, but temperature is indeed a part of the influence, and it is a part that cannot be separated from others.

Yes, the temperature of the water affects the extraction of coffee juice, but the reason why it is good or bad, can not depend on the water temperature, but depends on the brewer's head that does not understand the coffee, the so-called "will kill not the knife, but the person", water is only a tool to be used.

Brewers are best able to have a certain degree of understanding of the coffee itself (through the accumulation of their own experience or find information in the book), according to its variety, origin will have differences in flavor, according to its degree of roasting determines the flavor of the promotion and retention, and then integrate the above two points, and then according to its grinding bean thickness to determine two points:

The height of "brewing water temperature" and the length of "brewing time"

Coffee is a drink to relax and enjoy, so choosing the right coffee beans, grinding them into the right shape, brewing them in the right container, and drinking them at the best temperature are all fun and interesting: )

1. coffee powder

The raw materials for brewing coffee determine the taste of coffee, and how to choose coffee powder depends on the type of coffee pot you make. Generally speaking, it is coffee powder ground with coffee beans. The grinding thickness of coffee powder is also different according to your machine. You can go to Starbucks to buy coffee beans. They can grind for you for free, but they will ask you what kind of shape you want to grind, or that kind of thickness. For example, the lower mouth is pointed, and it is ground into diamond shape. Just tell them what size your coffee pot is and they'll grind it to the right thickness for you. this is very convenient.

2. water

What kind of water is also an important factor affecting the taste of coffee. Do not know where you live, how the city's water quality, such as Beijing's water is too hard, coffee taste will be greatly reduced, it is best to use canned mineral water to cook. Pure water is not a good choice.

3. Ratio of water to coffee

Can be adjusted according to your preferences, but the general heavy roast coffee powder, the amount of water should be slightly more, otherwise, the taste will affect the aroma of coffee.

4. Water temperature and cooking time

This is the most important part of brewing coffee. Of course, if your coffee pot does not need to be adjusted, there is no trouble, but usually the coffee brewed in this way has no difference in taste. Usually, the temperature can not exceed 90 degrees,(of course, this is also related to the local boiling point), the most suitable temperature is 85 degrees, master these can make a good taste of coffee. In terms of brewing time, depending on the shape and thickness of the coffee powder, it must match your coffee pot, as long as the water is fully in contact with the coffee powder and fused.
