To make a good cup of coffee, we have mentioned the importance of choosing beans and how to preserve them. However, having good beans also requires good craftsmanship to make a cup of mellow coffee. Although you and I are not professional coffee brewers, we only need to master a few key points to avoid drinking bad coffee. GQ asked uncle coffee to solve the doubts of brewing coffee by hand, so that you can easily make a good cup of coffee at home!

Which kind of water is the most suitable for brewing coffee?

What kind of water to use to brew coffee has always been a doubt in the minds of many people. In fact, the taste of coffee brewed by different water will be different, and everything depends on personal preference. Many people will think that there are too many impurities in tap water, which will affect the taste of coffee, so they switch to RO reverse osmosis water, but because the reverse osmosis water is too clean to extract the essence of coffee, the coffee taste is relatively poor; it uses trace mineral water to make coffee, but it tastes better, and some people will use mineral water to brew it. However, I personally think that there are some filter kettles on the market, using filtered water to make coffee by hand, the taste is the best, you might as well try it. But I still want to remind you that you still have to make a judgment according to how you drink.

What is the best water temperature for brewing coffee?

Often see that many people will directly boil the boiling water to brew coffee, in fact, this kind of water is not very suitable, the coffee taste will be too bitter, not easy to import. The water temperature that is really suitable for hand-brewing coffee is about 85 degrees Celsius to 92 degrees Celsius. If the water temperature is too low, it will taste sour. On the contrary, if the temperature is too high, it will be bitter, because the water with higher temperature will have more coffee powder extract. Although it is generally believed that the more the extract, the stronger the flavor, it is not the best taste, and there may be miscellaneous flavors dissolved into it.

When brewing coffee, how to handle the ratio of water to coffee powder?

Hand-brewed coffee has become more and more popular in recent years, but some people still don't know the ratio of coffee powder to water when brewing, or they are still groping to adjust it. In fact, the best powder-to-water ratio is 1:10, that is, 10 grams of coffee powder, it is recommended to use 100cc water, the extracted coffee tastes best. However, some people will use a method to make the coffee taste more layered. For example, today, 30 grams of coffee powder is used, but only 280cc water is used to brew it, and finally pour into 20cc boiled water. Since there is only 280cc in the water passing through the coffee powder, according to reason, this cup of coffee will be more full-bodied, but after being mixed with plain boiled water of 20cc, the original rich flavor can be pulled away and the taste will be more layered.

As for the powder-to-water ratio of espresso is different from that of hand-brewed coffee, we often hear that Espresso is also paired with three terms Single, Double and Ristretto, which represent different concentrations of coffee. The common Single is about 9 grams of coffee powder will rush out of 30cc coffee; Double is 18 grams of coffee powder washed out of 60cc coffee, as for coffee with a Ristretto of about 14 grams and 16 grams, the taste and phase will be thicker than Single.
