What is the best temperature to taste coffee? Suggestion on the best brewing temperature of hand-brewed coffee beans

Many friends privately wrote backstage,"What is the most suitable drinking temperature for coffee?" This question also made Qianjie not know where to start.

"Generally speaking, the temperature of drinking coffee is not recommended to exceed 55 ° C!" "Why?" "Because it burns your mouth.

"Okay, okay! The joke's over! Now for the serious bullshit.

This question, Qianjie is to see clearly, this friend actually wants to know is at what temperature coffee flavor is best, drink the most fragrant and comfortable. To understand this problem clearly, let's not start with coffee, but understand our taste buds. Our tongue can perceive five flavors, of which the sour, sweet and bitter taste of coffee is the most easily perceived taste. Coffee is a mixture of sour, sweet and bitter substances.

Usually the sour and sweet substances outweigh the bitter substances, and this cup of coffee will take on a sweet and sour fruit flavor, which is also our favorite flavor. If the bitter taste is obvious or sour, it is not pleasant. Temperature also affects our perception of sweet and sour. We feel sweet most when the temperature is above and close to human body temperature. For bitter taste, the perception becomes more obvious as the temperature decreases (normal temperature). Our perception of sourness is unaffected by temperature.

In addition, the most important flavor of coffee we drink comes from aroma. The aroma of coffee that has just been washed out is the most abundant, and after the temperature drops, the aroma also becomes heavy. For example, we can smell (drink) rich jasmine and citrus flavors in a cup of washed rose coffee when it is hot, but after cooling down, the aroma of jasmine and orange is not so obvious, and it is filled with honey aroma. This is not to say that coffee doesn't taste good when it's cold, but it doesn't taste as good when it's hot (rich in flavor). Therefore, hot hand-brewed coffee is suitable for tasting in the temperature range of 35-45℃. Brew a cup of coffee at 90 ° C in about two minutes. Its temperature is about 65-70℃, at such a high temperature, it is easy to burn the tongue, and it is difficult to feel the taste at too high temperature. So if the coffee is too hot, you can smell the coffee aroma, which is also part of the coffee taste.

Of course, you can also learn from coffee practitioners, from high temperature to low temperature, feel the coffee flavor changes at different temperatures. Also a friend asked, coffee into a thermos cup or reheated, can maintain the taste? The answer is no. It has little effect after drinking it in a thermos cup for 1 hour. However, after it has been put for a long time or reheated after cooling, the volatile aroma compounds will not come back, so they cannot restore the previous flavor. Another friend wants to ask, the lower the temperature you say, the more bitter it is. Why don't I have this feeling when I drink iced coffee? Here we have to say about the practice of iced coffee, the common ice hand red practice, is to extract the coffee in the middle and front of the material plus ice cooling dilution.

That is to say, more bitter substances in the middle and later stages have not been extracted. On iced coffee, the sour and sweet taste can cover the bitter taste, and it will not taste bitter. But if you smell iced coffee and hot coffee, the aroma difference between the two is too big.

Therefore, guests often ask Qianjie, is this coffee hot or cold? Front Street often gives the answer that the sensory experience of hot coffee flavor will be more complete, but in the end to drink hot or cold, you must follow your own preferences.
