The difference between ice drop coffee and hot coffee with ice

It is often seen that some coffee friends confuse iced coffee (or iced coffee) with iced coffee after hot coffee is added to ice cubes, and some coffee shops or hotels use this to deceive consumers, so this post introduces the difference between them and the fundamental difference in connotation.

Iced coffee is fundamentally different from iced coffee.

Iced drop (or iced brew) coffee and iced or iced coffee may seem like a word difference, but the two are essentially different in extraction and must not be confused.

Ice drop (also known as ice brew) coffee refers to coffee drinks extracted by long-term low-temperature immersion in water below 5 degrees Celsius.

Iced coffee or iced coffee refers to cold coffee that is quickly extracted with hot water and then added with ice or cooled rapidly.

There is a big difference between the two in terms of extraction method and time:

1. Hot coffee is hot water higher than 80 degrees Celsius or above 85 degrees Celsius; Second, it must be extracted quickly, because too slow will make coffee extraction excessive cause miscellaneous taste, and the main substance causing miscellaneous taste is tannin, boiled tannin will decompose into Jiao Wu acid, and tannin is easy to dissolve and decompose in hot water, it is the main culprit causing our coffee to be too bitter, we generally have to be careful to avoid excessive extraction of tannin and caffeine substances, this is our coffee lovers for a longer time know the basic common sense;

2, ice drop coffee is to use must be lower than 5 degrees or even close to the freezing temperature of coffee extraction, so that the various components contained in coffee in ice water is not easy to extract, so we must take a fine grinding slow extraction method, the specific method is to let coffee powder soaked in ice water for a long time, with a very slow drip speed extraction, the general standard speed is 1 drop per second, 45-50 drops per minute, generally takes 8-12 hours. Although it takes a long time to wait, its biggest advantage is that our most hated tannins will not decompose almost completely in cold water, caffeine will decompose in ice water, but it is reduced by about 90% compared with hot water extraction, while the other main components of coffee are the same. Because there is no astringency in the iced coffee, although there is a bitter taste but very little, so the iced coffee in the taste is particularly pure, this is also a long wait compensation.

By comparing the two analyses, you can see that the fundamental difference between hot coffee and iced coffee lies in the difference in extraction temperature and the amount of substances contained in coffee, not in the final cold drink or hot drink, hot coffee can of course be added ice after cold drink, and iced coffee (or iced brew) can also be heated after hot drink (experts recommend it is best to heat it over water to avoid direct heating to induce miscellaneous taste).

This is also why you want to order a real Dutch iced coffee in a coffee shop or hotel, not only need to book at least one day in advance, but also its price will be much higher than the general hot coffee reason, is the so-called "who knows the liquid in the cup, drops are hard", this is also worth our more light a little silver pay.

How to distinguish iced coffee from iced coffee

Because of this, I often find that there are some bad coffee shops or hotel baristas who add hot coffee to ice to cool down and pretend to be authentic iced coffee to deceive consumers to earn high profits.

In fact, the differences between them are easy to distinguish, there are two ways:

One is that real iced coffee, after at least dozens of hours of full filtration and fermentation, will immediately have an indescribable strange aroma after opening the bottle, which is the kind of aroma that hot coffee absolutely does not have, and this aroma cannot be replicated by any other method, unforgettable. So when you doubt whether it's real iced coffee, ask the barista to bring up the original iced coffee without sugar and milk for a sniff.

Second, taste and feeling, ice drop coffee does not have any astringent taste, caffeine content is very small, drink up the taste is very clean and refreshing, even drink a few cups will not have any palpitations or insomnia and other negative effects. After adding ice to hot coffee, it only reduces the temperature, but caffeine and tannin are not reduced, and there will be a big difference between the taste and the feeling after drinking.

The origin of iced coffee

Java Island, Indonesia, was colonized by the Netherlands in the 17th century. It is said that the coffee extraction method used here was introduced by Dutch merchants, so it was named Dutch Coffee. This type of coffee has been dripped with ice water for a long time, so it is also called "cold brew coffee cold" or "water drip coffee".

Iced coffee is coffee that has been dripped with ice water for 8-12 hours at room temperature. Although the aroma is not strong, it will emit a unique aroma, which cannot be obtained when extracted with hot water. The biggest advantage of this coffee is that it is quite pure and has no extra impurities, but it can give full play to all the ingredients contained in the coffee.

There are two ways to extract iced coffee. One is the traditional method still used in many parts of Indonesia today-dripping coffee in a lead bucket; the other is the method of dripping coffee using an all-in-one machine (the ice drip pot we often see in coffee shops consists of a glass top pot with a drip switch, a glass pot with coffee powder connected to a glass serpentine pipe, and finally dripping into a glass flask). Ice-drop coffee appliances that use the drip principle are reminiscent of laboratory tools. They function well and look quite spectacular. These alone can stimulate my curiosity. Ice drops are made with a variety of tools, and the price is quite high, mainly made and sold by Japanese merchants.

From this point of view,"cold brew coffee cold" or "water drip coffee" refers to a meaning, and there is no essential difference, just different terms and names of the same thing.

If we are talking about differences, I think the term "ice brew" covers a wider scope. It can refer to ice drops or cold bubbles.

Toddy coldbrewers are the easiest way to make iced coffee

The method of extraction by immersion in ice water is another way of making iced coffee in Java and other parts of Indonesia, called traditional cold brew. It does not require any technique or machinery and is the most natural way to extract coffee.

Todd Simpson, on a business trip to Guatemala in 1962, ordered coffee at a restaurant. However, the only thing in front of him was the black extraction liquid in the pot and the hot water that had just boiled. The clerk poured the hot water into the black liquid and handed it to him. He couldn't forget the creamy, rich taste of coffee he had drunk, and when he got home he studied it deeply. In fact, the coffee he drank was made by a method commonly used by Dutch settlers in Java in the 19th century. He named his invention Toddy. At Seattle Gourmet Coffee and Jean Coffee Beans, a cold-brewed coffee extract used for iced coffee, Toddy is also a fan.

Ice drop and cold bubble the same point is to soak coffee powder in ice water and extract coffee liquid, two production methods have their own characteristics, ice drop method tools gorgeous spectacular, pure and natural taste; cold bubble method tools simple, rich and smooth taste, especially suitable for home and office.

The picture shows the Dutch traditional ice drop coffee pot (eight people), the appearance is quaint and gorgeous, like a piece of art, but the traditional ice drop pot is generally more expensive (fast catch up with an entry-level Italian machine), operation and cleaning must be careful (glass pot especially serpentine tube is easy to break, once broken is very difficult to supplement oh, so weekdays often break the cup, hairy big brothers and little brothers should not use).

This is a Toddy type cold brew coffee pot made in Japan. It is affordable, convenient and fast. It is also very simple to operate. Anyone who does not know coffee can also use it to make refreshing cold brew coffee. Just put the coffee powder into the cup and insert it into the glass pot. Pour ice water and stir it for a few times. Then put it into the refrigerator for 8-10 hours. After the soaking time is reached, take out the cup filled with coffee powder. Then also don't forget to keep the iced coffee liquid refrigerated for at least 24 hours (the best time is 3 days), you can take it with you, this cold bubble pot is most suitable for home and office use, don't look at it is not amazing, but it brewed ice coffee delicious absolutely let you amazing, is the so-called "people can not judge, the sea can not fight the amount", this is also my summer use of the most frequent coffee pot.

Although ice brewed coffee tools are sometimes difficult to find, there are also many ways to save trouble. Coffee friends at home and abroad have created many unique and amazing methods for making ice brewed coffee, such as using three mineral water bottles of different sizes to make ice drop coffee. Another example: If you already have a set of hand brewing system can be fully utilized, take an empty bottle to coffee powder and ice water poured into shake mix, sealed into the refrigerator 8-10 after taking out, with Melita or Carita cup filter paper filter coffee grounds after adding ice to drink, the same delicious, in addition to the use of pressure pot can also be very convenient to make iced coffee, no matter what method, as long as it conforms to the principle of iced coffee production, They taste just as good as regular Dutch ice drippers and Toddy cups.
