The charm of hand-made coffee is that you can make your own cup of coffee and enjoy the slow life in a relaxed state. In Qianjie, many articles have been written about brewing coffee, so in this next article, Qianjie coffee will come to popularize the knowledge about how much water temperature it takes to brew coffee by hand.

The so-called hand-brewed coffee is that the barista controls the parameters such as water temperature, water flow, water volume, and the fineness of coffee powder, and brews coffee powder in a stable way to complete the extraction of coffee.

According to the soluble substances in coffee powder, sour taste is the first to be extracted, followed by sweet taste, and finally bitter taste, and the degree of release varies with different water temperature. generally speaking, "the shallower roasted coffee beans will accelerate extraction because of their higher density and higher temperature of water." The deeper the roasted coffee beans are soft, they will be boiled in lower temperature water to slow down the extraction rate. "the higher the temperature, the faster the extraction, but it is also easier to over-extract, resulting in bitter or scorched coffee, on the contrary, the temperature is not enough to make the coffee extract insufficient, the coffee body will be thin, and it will have a more sour taste.

Generally speaking, the texture of shallow roasted coffee beans is denser, the situation of expansion in case of heat is less obvious, and the speed of water extraction is slower, so the way of brewing coffee powder and water can be contacted for a long time will be used. and slow water injection, with high-temperature water to stimulate extraction, the success rate of coffee powder layer expansion will also be greatly improved.

With the characteristics of high acidity and low concentration, the taste is sour and sweet, floral and fruity, and the texture is relatively fresh.

When using medium-and deep-roasted coffee beans, it is recommended that the temperature be slightly lower to slow down the extraction speed, and at the same time, water is injected gently and at a low height close to the filter cup, so as to ease the impact of water on the coffee powder layer and reduce the proportion of coffee tail bitterness. and then balance the overall flavor of coffee.

With a thin grease on the outside, it tastes soft and fragrant, not sour but not bitter, and can drink warm flavors such as caramel and cream. the most classic medium and deep roasted coffee is Manning.

If you want to brew espresso by hand, in addition to lowering the water temperature and grinding coffee powder a little thicker, you can also pay attention to the luster of coffee beans. Fresh deep-roasted coffee beans have full fat. It can increase the mellow and fragrant taste when drinking, prolong the contact time between coffee powder and water when water injection, and the oil can be dissolved more completely.
