How long does it take for coffee to have an effect? How long can I take coffee after drinking? 20

This varies from person to person, some people drink coffee without effect, while some people drink tea and get sleepy.

Look at the physique, some people drink coffee and sleep soundly.

Coffee can be as short as 2 hours or as long as 1 year.

Coffee cannot be drunk, depending on the form of coffee, and the time it can be drunk varies depending on the form, from as short as 2 hours to as long as 1 year. The shelf life of different coffees is mostly different, and in principle, the sooner you drink a good coffee, the better. If it is a roasted coffee bean, it should be drunk as soon as possible within 3 months, and if the coffee beans have been ground into powder, it is best to drink it within 3-5 days.

If it is instant coffee, there is a shelf life behind the general product, which needs to be determined according to the shelf life, half of which is about a year, and it is not recommended to drink it after the shelf life. If it is brewed coffee, it is recommended to drink it within 2 hours, generally not more than 4 hours, otherwise it will affect the taste and may also deteriorate. If you can't finish it, you can also make it into iced coffee, which can be stored for a longer time.

Coffee

Coffee is a beverage brewed from roasted coffee beans, and it is one of the world's three major beverages along with cocoa and tea. Coffee trees are grown in more than 70 countries, mainly in the equatorial regions of the Americas, Southeast Asia, and India. Coffee is made from coffee beans and a variety of cooking utensils.

Coffee beans refer to the kernels in the coffee tree fruit, which are roasted in an appropriate way, and their taste will show different degrees of sweetness, acidity, body or cleanliness.

In general, it is best to drink instant coffee as soon as possible after brewing, although overnight coffee will not produce carcinogens, it is still unhealthy to drink. If unsweetened black coffee is left in the refrigerator overnight, the main problem is that it is not fresh and the flavor of the coffee is destroyed; If the coffee has added sugar or milk, but you buy it but don't finish it right away, or even continue to drink it overnight, the problem is bigger.

Coffee often has added sugar and milk, and if you don't drink it right away, it can easily spoil, and sugar is a favorite of bacteria! It is recommended to use stainless steel thermos cups for coffee to reduce bacterial growth, but it is best to buy and drink it now!

Can you drink coffee overnight?

As for the question of whether the overnight coffee can be drunk, whether it is overnight water or overnight coffee, leaving it for too long will cause the water quality to deteriorate. If boiling water is boiled many times, it will cause the nitrite content in the water to increase, and the same is true for coffee, so it is not recommended to drink coffee that has been reheated repeatedly.

In addition, the composition of coffee aroma is complex and diverse, containing more than 900 different flavor substances, which are released when heated and destroyed by light and oxygen. Therefore, if the coffee is left for a long time, the aroma will not be as strong as when it is fresh. The aroma component of coffee is what makes coffee so pleasant, focused, and productive.

Coffee that loses its aroma component will greatly reduce its refreshing effect. Therefore, it is not recommended to drink coffee overnight.

Milk tends to spoil and coffee is not fresh overnight.

The first reason is that milk is rich in protein and is prone to spoilage and even spoilage. Everyone knows that fresh milk should be drunk as soon as possible after leaving the refrigeration, but it is ignored that latte also contains a lot of milk, whether it is an iced latte or a hot latte, it will spoil after a long time at room temperature. Therefore, if the latte has been on the table for several hours, even if it is put in the refrigerator later, it has actually deteriorated, which may cause gastrointestinal problems such as diarrhea.

If coffee is sweetened or milk every day, it is more likely to spoil and grow bacteria.

Sugar is a favorite of bacteria overnight coffee and many bacteria.

As for the second reason, nutritionist Song Minghua pointed out that sugar is a nutrient that bacteria particularly like, and sweetened coffee is left idle for too long, so be careful to turn it into a petri dish for bacteria. Even if you store it in the refrigerator, don't forget that the refrigerator is not sterile, and the coffee cups are often not sealed, which can continue to harbor bacteria.

Freshly brewed coffee is fresh, and the taste and flavor are also at their best.

It is best to use a thermos cup to strengthen the preservation.

In short, overnight coffee will be greatly compromised in terms of hygiene and taste. Remind everyone that coffee is best brewed and drunk! If you really can't finish it right away, you can put the coffee in a stainless steel thermos cup to use its sealing and heat preservation properties to reduce bacterial growth.

However, it is better to store it in a thermos cup than to put it at room temperature, it does not mean that it can be stored for a long time, and it is still necessary to drink it as soon as possible to be healthy!

The best drinking days of freshly ground coffee powder are 7 days, and the flavor can be retained for 1 month, but the storage method should be sealed. It is recommended that you go to the Foshan Coffee Forum to make a post about coffee powder and how to store it, which is very detailed.

Questions. No, I said that there is a lot of coffee in the Moka pot now, can I drink it tomorrow if I can't finish it?

It is not recommended to drink it overnight. Sugar and milk are often added to coffee, so it is very easy to breed bacteria and microorganisms, and if the coffee is left overnight, it may spoil, and the human body eats spoiled food, which may cause greater harm to health. And the aroma components of freshly ground coffee are complex and diverse, with more than 900 different aroma substances, which will lead to a large loss of aroma after a long time, which greatly reduces the drinking value of coffee, so it is not recommended to drink freshly ground coffee overnight.

Questions. Good. Hee-hee].

If it's about causing physical harm, I'm not sure it's going to be a problem. But in terms of quality, after the coffee is brewed, the temperature will decrease over time, the aromatic substances will be released, and the taste will deteriorate. So after 24 hours, I really haven't had a good coffee except for the iced coffee made in the ice drip pot.

It is recommended that if you don't drink the coffee in time after making it, try not to drink it. Unless you're frugal and don't care about the taste of coffee, or have other purposes. If you have to leave it a little longer (I nag, don't kick me!)

It can be put in a thermos cup, and I once met a guest who did just that. But the specific taste, I haven't tried it.

Or you can put a small amount of ice cubes in the coffee after making it, and then seal it and refrigerate it. The main purpose is to preserve the aroma and taste of the coffee. In the case of what LZ said, it should not be easy for that cup of coffee to taste other delicious flavors besides bitterness.

Coffee can generally be stored for a few hours after brewing. Pregnant and lactating women should be cautious about drinking coffee to avoid adverse effects on the fetus and newborn. Older people with cerebrovascular disease or diabetes should drink as little coffee as possible.
