What are the factors affecting hand-brewing coffee with tips on hand-brewing coffee?

Cold in winter is very suitable for a cup of hot coffee, but I don't know if you have found that when brewing coffee in winter, it is obviously the same extraction parameters, but the taste of the coffee is different. This is due to the change in temperature. Today, the editor will come to talk to you about what you should pay attention to when making coffee in winter.

| | preheating apparatus |

The editor suggests preheating your brewing utensils, such as hand pots and filter cups, before making coffee. Most of our hand pots are made of stainless steel and copper, and their heat absorption capacity is still very strong in winter. when the boiling water is poured down, it may suddenly become more than 80 degrees Celsius. It is easy to get a cup of coffee with insufficient extraction at such a low temperature.

The common materials of the filter cup are resin, ceramic, glass and metal. In addition to the filter cup made of resin, the filter cup made of ceramic, metal and glass will become cold and cool due to the decrease of ambient temperature. when supplying water, the hot water will cool as soon as it touches the cup wall, and there may be a temperature difference of 2-3 degrees. So, if you want to have the same cooking conditions in winter as in summer, Xiaobian suggests that you should first preheat the cup with some hot water in the hand pot, and then rinse the filter cup with hot water so that the filter cup wall is not too cold. Even fill your filter cup with more hot water and let the filter cup wall absorb heat thoroughly, which has a great impact on the maintenance of cooking temperature.

When the temperature is high in summer, the change of the water temperature in the hand pot is not obvious in 2-3 minutes, but when the temperature is lower in winter, the hot water may cool quickly, resulting in the lower temperature in the final cooking and the lack of body in the latter half, so the taste will be a little thin and the aftertaste will not be long. Therefore, the editor suggests that when you pour hot water into the pot, you can pour more hot water into the pot than usual. A sufficient amount of hot water can make the hot water in your hand-flushing pot resist the cold room temperature and maintain the water temperature, so you won't be afraid to rush to the second half of the extraction and have no taste.

| | increase the cooking temperature moderately |

If you have preheated the utensils and increased the hot water in the hand-flushing pot, but the flavor is still not as full as in summer, it is possible that your environment is really steep. For example, strong wind and high humidity will quickly take away your temperature (whether it's a filter cup or a hand flushing pot), resulting in insufficient extraction. So let's appropriately increase the initial water temperature to fight against the cold environment. For example, if you usually use 88 degrees water, increase your extraction rate by 2 degrees to 3 degrees.

In addition to the flavor effect caused by temperature, in fact, the decrease in body temperature will also affect our taste preference, cold weather, more abundant taste will make people feel comfortable and relaxed, like a bowl of thick soup, will comfort your nervous and cold body. So if you are used to using a low powder-to-water ratio, drinking it in a cold winter may give you the illusion that it is not good enough, but it is not the problem of coffee itself, but the needs of the body, and this problem is not difficult. A slight increase in your powder-to-water ratio can make a significant improvement.

If you usually use the 1:15 powder-to-water ratio, try using the 1:14 powder-to-water ratio to increase the overall concentration of the coffee and make your body feel comfortable and the taste buds will naturally feel satisfied.

The temperature of the water has always been an important thing for brewing coffee. If there are great changes in the environment for brewing coffee, such as temperature, humidity, wind. While waiting, don't forget to be flexible and modify your brewing data slightly in order to get a cup of high-quality coffee.
