Iced coffee, iced coffee and cold coffee seem to be similar in concept, but they are made in different ways and their flavors are also very different. Recognize the difference in order to find your favorite flavor.

Extraction mode and time

Iced coffee or iced coffee refers to a cold drink coffee that is quickly extracted with hot water and then added with ice or cooled rapidly. However, hot coffee needs to be brewed with hot water higher than 80 degrees Celsius or above 85 degrees Celsius and extracted quickly, because too slowly it will cause excessive extraction to cause miscellaneous smell, and the main substance that causes miscellaneous smell is tannin, which is intended to decompose in hot water, making coffee bitter.

Ice drop coffee (ice drip) must be extracted at a temperature below 5 degrees Celsius or even near the freezing point, and the coffee powder must be extracted for a long time at a slow drip rate. In general, it takes about 8 to 12 hours. In terms of equipment, commercial trickling devices are like laboratory appliances, while household appliances are generally smaller devices. Its biggest advantage is that tannic acid in low temperature ice water, almost no decomposition, low acidity, high caffeine concentration.

Cold brew coffee and ice drop coffee are extracted at a low temperature, but the coffee powder is completely soaked and then filtered with cloth or filter paper. Soak the coffee powder in a larger container at home, and you can make your own cold coffee.

Taste difference

Ice drops and cold soaked coffee are extracted for a long time, will send out a unique aroma, no bitter taste, taste clean. This is the biggest difference from chilled coffee, especially when it is extracted with hot water and then chilled, the acidity and bitterness of the coffee still exist.

There are special ice drops of coffee, cold soaked coffee in the process, will be completely immersed in coffee powder, taste thicker than ice drops, acidity is also higher than ice drops. On the other hand, the concentration of ice drop coffee is higher than that of cold brewed coffee, and it contains more caffeine, so it can be drunk with water according to taste.

"can I still drink coffee overnight?" This is indeed a very good question, because busy people are very likely to buy a cup of coffee but are too busy at work and leave the coffee at hand because they are too busy or for other reasons. some people will choose to keep it in the refrigerator and continue to drink it the next day, but this raises a question: can you really drink coffee overnight? Have you ever heard of not drinking overnight tea? what about overnight coffee? In fact, coffee and tea are two different things, tea overnight will produce thick tannins, it is normal to taste worse, but coffee is different, whether coffee can be drunk or not depends entirely on the type of coffee itself and the way it is preserved.

Can I still drink coffee overnight?

There are many different kinds of coffee, such as black coffee, mocha coffee, cappuccino and latte. Etc., among which black coffee (that is, coffee without any additives) can actually be drunk overnight, but the previous topic is that it has not been drunk and properly encapsulated and stored in the refrigerator, and it will deteriorate if it has been touched with saliva. Even if it is placed in the refrigerator overnight, it will also change the flavor, even fermentation or bacteria can not be drunk, if it is black coffee with sugar, it should not be put overnight. Because sugar is the most popular living condition for bacteria, coffee will breed bacteria even if it is put in the refrigerator overnight, and should be discarded if you can't finish it that day or even if you don't finish it within hours.

Coffee with milk in the refrigerator also breeds bacteria overnight.

Black coffee with milk into latte, cappuccino or mocha coffee and other different flavors, no matter which kind of coffee with milk is recommended to drink under the most suitable conditions, that is, within dozens of minutes, because the milk itself will soon deteriorate and ferment at room temperature, according to the length of fermentation time of different temperature, the hotter the weather, the faster the fermentation speed, some people's intestines and stomachs are more sensitive. If you drink a little fermented milk, you will have a stomachache or diarrhea and want to go to the toilet. Lattes, cappuccinos or mochas, such as lattes, cappuccinos or mochas, are all types of coffee that can be easily fermented. As long as it is fermented, it will breed bacteria, and it is not suitable to drink overnight even in the refrigerator.

Ice drop coffee is ice brewed.

How many kinds of coffee are there? In the world of coffee, there are some special exceptions that can be drank every other day or every few days. what we want to talk about is ice-brewed coffee, which is often called ice-drop coffee or water-drop coffee. The coffee extraction principle it applies is that ice water is extracted slowly at ultra-low temperature, slowly taking out the essence of coffee, in order to give ice-brewed coffee an excellent flavor. Usually, you have to put it in the refrigerator for a few days before you can drink it. this process is called ice brewing. the production process of this kind of coffee is controlled at a low temperature, and it is also put into the refrigerator to let it ferment naturally, giving off the special flavor of the coffee itself. in principle, ice-brewed coffee is black coffee without any additives, but after drinking it, you should also drink it at once, and don't put it back into the refrigerator to drink it every other day. So as not to deteriorate due to contact with saliva.
