Coffee beans-can I put the brewed coffee in the refrigerator?

As different people have different tastes, different requirements for shade are different. The range of extraction concentration is 1.15% Mel 1.35%, and the proportion of water used is about 1:13 to 15. Some people use very little water simply in pursuit of richness, but it doesn't taste good. On the contrary, some people expect to extract more substances with more water, but they do not realize that the later the extraction is, the lighter it is, and the final concentration is not enough.

Whether the aroma and hierarchy of coffee can be released heartily, the key lies in water injection. Common mistakes are:

a. The injected water column is too large and the direction of the water column is too tilted, which will cause the water to flush a hole in the side of the powder layer and run away directly from the filter paper, resulting in insufficient coffee extraction.

b. The water column is pulled too high, resulting in the flow of water to destroy the coffee powder, easy to inject bubbles, and uneven coffee extraction. It will also lead to too much water column and contact air area, and the water temperature will be affected, so the water column must be as close to the coffee as possible.

c. The water flow is unstable, sometimes large and small, sometimes dashing, sometimes ticking off, resulting in different degrees of soaking in different areas of coffee powder, and the taste of coffee will be affected.

The best temperature for drink coffee is 85-88 degrees Celsius. Because the texture of ordinary coffee is not stable, it is best to taste it while it is hot. In order not to reduce the taste of the coffee, soak the coffee cup in boiling water beforehand. The appropriate temperature for coffee is 83 degrees Celsius at the moment of brewing, 80 degrees Celsius when pouring into the cup, and 61-62 degrees into the mouth, which is the most ideal. Generally speaking, tasting the coffee served by your host while it is hot is also the basic etiquette of drinking coffee. If a cup of high-quality coffee, after cooling, in addition to the aroma will be reduced, the taste performance is consistent with the hot, or even better. Taste: coffee beans contain about 5-8% sugar, most of which are converted to caramel after baking, which is the source of aroma and bitterness, leaving a little sweetness in the unconverted sugar; tannin is released during baking and combines with caramel to produce a slightly bitter sweetness. Therefore, people's taste of coffee is generally bitter, sour, sweet, fragrant and astringent. Moderate amount: drinking coffee is not like drinking or juice, a full cup of coffee, watching it will lose interest in drinking. Generally, it is only seven or eight minutes full for the right amount, moderate amount of coffee will not only stimulate the taste, after drinking it will not have a greasy feeling, but endless aftertaste. At the same time, the right amount of coffee can moderately promote the body to recover from fatigue and refresh the mind. Coffee has a strong and weak taste, so you can't drink several cups in a row like tea or cola, and the average amount of coffee is 80-100cc. Sometimes if you want to drink three or four cups in a row, you have to dilute the concentration of coffee, or add a lot of milk, so as not to cause nausea, and you might as well change more in the blending of sugar to make the coffee more delicious. Are you satisfied with my answer? Iced coffee doesn't hurt, but it tastes a lot worse. In order to be hungry, you can taste coffee well and be hot.

The air in the refrigerator is cold and dry, so it is easy to evaporate the moisture in the beans and lose the fragrance; in addition, there are too many miscellaneous smells in the refrigerator, so it is more appropriate to use vacuum cans to preserve coffee beans. When coffee beans are first taken out of the refrigerator, because the temperature of the beans is too low, they will condense water vapor in the air and form small water droplets on the surface. After grinding, these droplets will form coffee powder into lumps, resulting in uneven brewing. Therefore, the coffee beans should be taken out of the refrigerator before use, after getting some of them, put the vacuum cans back into the refrigerator as soon as possible, and quickly grind the coffee. If the whole bag of coffee beans is no longer put back in the refrigerator, it should be taken out an hour before use and unsealed after returning to normal temperature at room temperature. In this way, the surface of coffee beans is less likely to condense water droplets. In addition, as the internal changes in the coffee are still in progress after roasting, if the beans just out of the oven are put in the refrigerator, the flavor will be interrupted. Therefore, fresh coffee beans are not suitable for the refrigerator. Stale coffee beans, such as those that last more than 20 days, can be stored in the freezer. Well, the answer is purple!
