94 degrees hot water hand-brewed Brazilian coffee-breaking coffee water temperature record

It has always been believed that the best temperature for hand-brewing coffee is about 90 degrees, and the highest is generally controlled at 93 degrees. This is not only a theoretical study, but also seems to have been done at a high temperature of 95 degrees in my memory. As a result, there is a cup of bitter black high concentration "bitter water". Once you suffer, you will remember that "the temperature is too high to make the coffee extract too bitter." So it seems that 93 degrees becomes a "limit height" in the subconscious during normal practice.

Today, when I was replenishing the coffee beans, I suddenly found that there was some Brazil in the bottle in the corner. It was not available to the guests. It was only about two cups. I did it by the way. I didn't think about it. pour the water temperature cup and drop the water temperature from 96 degrees to 94 degrees. "stale beans, the water temperature should be higher, right? What's more, Brazil is already bitter, and it doesn't have much acidity, so it just does so. "with a little thought in my head, it rushed out easily, hey! The result really surprised me! Brazil, which has always been moderate and calm, unexpectedly exudes the sunny aroma of September, which is neither floral nor obvious fruit, but it seems to combine the two with the warm and crisp aroma of some roasted sesame peanuts! Take a sip. Hey! Bitter sweet, unexpectedly surprisingly pure, this is not like the previous Brazil is bitter and heavy! Thinking that there was something wrong with his mouth, he hastened to call his younger brother to taste it. Even he said that the taste was pure, unlike Brazil. Strange? 94 degrees hot water? Is it the coffee beans? Brewing problem? Or the temperature of the water? It's a pity that only a few beans can no longer be copied.

Puzzled, I took a look at the coffee beans and aimed at Colombia on the 17th! after 10 days, it is "old" enough. I wonder if I can withstand the high temperature of 94 degrees. One drink out. Hey! Not bitter, but also surprisingly blooming sunny day in the aroma, the taste is also the same clean, although the mellow and richness is still poor, make another cup, the taste is still so pure, and the fragrance in the aroma is refreshing! When I made another cup, it came out like the lemon fragrance of Yejia Xuefei. It's all 94 degrees hot water! For comparison, I made a 90-degree one later, and as a result, the bitterness and turbidity came out obviously.

strange! strange! After thinking about it all afternoon, I didn't come up with a reason, but it seems that many things that seem to be "regular" may not be applicable to all situations. Even if they usually look like a "restricted area", they should break into the area and not once. Who knows what will happen the second and third time? Those so-called scientific laws are constantly being overturned and updated. There should be more changes in the world of coffee, but our mouths will not deceive us, so keep trying.
