Three mistakes often made by people who like to drink hot coffee how to keep hot coffee reasonably?

Many people like to drink hot coffee, and it is fresh hot coffee, because coffee has the strongest aroma when it is hot.

Although good coffee still has a good flavor when it is cold, many people are still used to drinking it at a high temperature, and if they don't have time to finish it when it is hot, they may keep it warm or even reheat it. But if it is not done correctly, it will lose its aroma, taste insipid and even make it scorched and bitter.

Here are a few common mistakes and the impact of these actions on the flavor of coffee, so that you can enjoy coffee correctly!

Mistake 1: use a heater to keep warm

Whether you put a whole pot of coffee on the machine or keep it warm in a mug with a USB slot, it actually keeps the coffee hot, which is like overcooking, distorting the taste of the coffee and making it worse.

Error 2: microwave

Microwaves are heated by radiation rather than conduction, which will lead to two problems. First of all, when the microwave oven is running, you can't check the temperature of the coffee, so it's hard to know how hot the coffee is, which often causes the coffee to burn. Second, because of the radiation heating, the cup of coffee will be inconsistently heated, causing some of the coffee to be overheated and some cold. Overheated parts will have a distinct scorched and bitter taste.

Error 3: press the kettle for heat preservation by heat insulation method

Using a French filter kettle with heat insulation may be able to keep the coffee warm by leaving the coffee in the filter pot, but even if you press down the device of the filter pot, the coffee in the pot will continue to extract the coffee grounds at the bottom, which will lead to excessive extraction of coffee, which is why the coffee must be poured out as soon as the brewing time of the filter pot is up.

Solution: switch to an thermostat

Whether we go out for activities, lectures or exhibitions, we use thermos to maintain the temperature of the coffee. Use an thermostat instead of any external heat source, but use the temperature of the coffee itself to keep it warm, and this will not lead to the problem of over-extraction caused by the use of filter pots.

The ideal brewing temperature for coffee is about 90 degrees. The freshly brewed coffee is too hot to drink. You can first pour a small amount of coffee you want to drink into the cup and put the rest in the thermos. A good thermostat can keep the coffee warm for hours.

Whether you like hot coffee, hot coffee, or you can accept warm and cold coffee, just remember the three main ingredients of coffee: fresh roasting, fresh grinding, and fresh brewing.

In addition, it is not recommended to flush the coffee grounds back. Unlike tea, coffee will extract most of the aromatic substances from the coffee the first time it is brewed. If the coffee is flushed back, it will only give off a mixed smell.
