There are many ways to brew coffee, and ice dripping is one of them. Iced coffee is another type of iced coffee. In summer, iced coffee is even more popular among coffee friends.
Ice drip coffeeNaturally, it is brewed not with hot water, but with low-temperature water. It is very different from our usual Pour over(V60) coffee. It is relatively simple and takes a lot more time. If you want to have a cup in a coffee shopIce drip coffeeMaybe it depends on luck!
In 1699, during the Dutch rule in Indonesia, a lot of coffee was planted on Java Island. Dutch immigrants in Java invented the method of making ice-drip coffee. At that time, they believed that the reason why coffee upset the stomach was caused by the sour taste in the coffee. After making it with ice water, the sour taste was reduced, so they were more willing to drink it this way.
Iced coffee, some people call it Dutch Coffee, espresso or drip coffee, also known as Dutch drip coffee. Iced coffee relies on the compatibility of coffee itself with water, mainly through the natural penetration of water pressure through condensation, and can be extracted drop by drop for about 8 hours. The characteristic of ice-drip coffee is that ice water is used to extract coffee. The low-temperature extraction requires a longer time to dissolve the aromatic substances in the coffee. Therefore, a dropper similar to a chemical experiment is used to let the ice water fall drop by drop, slowly infiltrating the coffee powder. In the traditional ice-drip coffee maker that is commonly seen, the speed of the water droplets can be controlled. Iced coffee, also known as water-drip coffee and ice-brewed coffee, is a way of making coffee drinks. A common ice coffee drip filter consists of 3-4 layers of glass containers placed on a wooden base.
What is the extraction principle of iced drip coffee?
Hand-brewed coffee is brewed with prescribed high-temperature water, time and powder-to-water ratio. It is simple and takes a short time. The advantage of high-temperature extraction is that it can quickly extract the flavor substances of coffee, causing the tannic acid in the coffee to quickly decompose into pyroic acid, resulting in sour, sweet and bitter, which is the process of releasing the flavor of coffee that is often said on the street. The disadvantage of high-temperature extraction is that it easily causes the coffee flavor to be completely released, and then begins to release the taste of the woody fiber of the coffee beans, which is what we often call unpleasant flavors such as miscellaneous flavor and woody flavor.
Iced coffee is a type of coffee that takes time to brew. We know that the taste of coffee brewed with different water temperatures will be different, and the astringent substances in coffee are not easily dissolved at low temperatures. Use ice water to extract for a long time, and after the extraction is completed, put it in the refrigerator for fermentation. The slightly fermented ice-drip coffee will have a light fermentation aroma and will have a thicker taste. Since it is not extracted at high temperatures, relatively few impurities are extracted from the coffee. Due to the long production time, the filtered ice-drip coffee cannot be drunk immediately, because the flavor molecules extracted at low temperature are completely released, but not well released. Therefore, after the ice-drip coffee extraction is completed, place it in a sealed bottle and put it in the refrigerator for 12-24 hours to allow the pressure of carbon dioxide in the bottle to release the flavor molecules. This is the best time to taste.
Ice drops have slightly less caffeine. For those who are affected by caffeine, Front Street believes that you can choose ice-drip coffee. It is not so stomach-breaking, and the caffeine is relatively low, and the coffee flavor is also very rich!
Making ice drops: Making ice drops is the same as making a siphon, and you must have a special appliance - an ice drop pot.
Steps to make iced drip coffee:
1. An ordinary ice-drip coffee pot is divided into three basic units: the upper pot, the middle pot and the lower pot. The upper pot holds the ice-water mixture, and the middle pot is the coffee powder cup. First, close the water control valve at the lower end of the upper pot and pour pure cold water or ice-water mixture into the upper pot.
2. Place the clean lower pot under the middle pot to receive the extracted coffee liquid.
3. Place a piece of filter paper flatly under the coffee powder cup, place an appropriate amount of ground coffee powder in it, tap it a few times to make the coffee powder flat, and then place a piece of filter paper flat on it.
4. Open the water volume control valve at the lower end of the upper pot and adjust the speed of water dripping. Generally, we control the speed at 40-50 drops/minute, so it takes 5 to 8 hours to obtain 1000 ml ice-drip coffee.
5. When the water in the upper pot is used up, we can remove the lower pot.
6. If you want the ice-drip coffee to show the best flavor, you can bottle the extracted ice-drip coffee and store it in the refrigerator. The coffee flavor will be at its best on the 3rd to 7th day, showing a complex and elegant flavor like fermented wine. No wonder it has won the reputation of "ice-drip fermented coffee", and its longest drinking period can be close to half a month.
Of course, it doesn’t mean that you can keep it for as long as you want. Front Street does not recommend keeping the ice drops for a week. After all, there are bacteria in the air or the bottle, and it is difficult to guarantee the condition of the coffee after being left for a long time. The drinking period of the ice drops is recommended to be within 72 hours. Don’t feel that the ice drops have been wasted after 72 hours. Drinking coffee that has been left for such a long time may not be good for your health.
Let’s share the iced drip coffee recipe that FrontStreet Coffee often makes.
1. Dark berry type：Costa Rica Mozart 60g,MozartThis coffee bean uses anaerobic honey processing method and has a very special raisin aroma. When used to make ice-drip coffee, it will show very obvious flavors of blueberry, black grape and wine fermentation, with a refreshing taste and a lingering fragrance on the teeth and cheeks.
2. Refreshing and clean type:Kenya Azalea60 grams, the acidity of Azalea is very lively, like a glass of juice. When used to make ice-drip coffee, it will have the fragrance of cherry tomatoes and grapefruit. It tastes refreshing and light with acidity, which is very suitable for drinking in summer.
3. Sweet and delicious：IndonesiaGolden Mandheling60 grams. Very few shops use dark roasted coffee to make ice drip coffee. If you haven’t tried it, you may think that the ice drip made from dark roasted coffee beans will be very bitter. In fact, this is not the case. Using the ice-drip making method from Front Street and adding ice cubes after being placed in the refrigerator for 24 hours, the Golden Mandheling ice-drip coffee is sweet and has a hint of chocolate bitterness. It is very clear overall and has a strong aroma of fermentation that is very comfortable.
It is made by adjusting the speed of water droplets and slowly dripping with cold water. It is extracted at a low temperature of 5 degrees Celsius and dripped for 8 hours for a long time, so that the original flavor of coffee can be reproduced naturally, which is even more exciting.
Features of iced drip coffee
The advantages of drip coffee: it is not sour, not stomach-breaking, and can be stored for up to a week. The flavor is best especially on the third day. The caffeine is also low. Because the coffee powder is 100% soaked and moistened at low temperature, the extracted coffee tastes fragrant, smooth, and rich, which is admirable. The flavor displayed is of course outstanding. Especially in the summer or when you have a cup the next morning, it feels refreshing instantly.
FrontStreet Coffee brewing suggestions:
Whether the coffee is brewed by hand, dripped with ice orItalian, as long as it is the taste you like, it is delicious. Front Street believes that any brewing method requires fresh coffee beans. Front Street has always believed that the freshness of coffee beans has a great relationship with the flavor of coffee. Therefore, the coffee beans shipped by Front Street Coffee are all roasted within 5 days. The purpose of Front Street Roasting is "freshly roasted and good coffee", so that every customer who orders receives the freshest coffee. The bean-growing period of coffee is about 4-7 days, so the flavor is at its best when customers get it.
For those who need to grind the coffee beans, Front Street would like to remind you that if the coffee beans are ground in advance, there is no need to raise the beans. Because during the transportation process, the pressure generated by the carbon dioxide in the packaging can also make the coffee flavor mellower, so you can make a cup of coffee immediately after receiving the coffee powder. But the coffee powder needs to be brewed in time, because the coffee powder oxidizes quickly when exposed to air, which means that the flavor of the coffee will dissipate relatively quickly, and the flavor of the coffee will not be so good. Therefore, Front Street recommends buying whole beans and grinding them freshly, so that you can better taste the flavor of the coffee.
