In South Korea, almost every cafe sells iced coffee and cold coffee, and many famous brands of ice drop appliances come from Japan and South Korea.

The difference between iced coffee, cold coffee (cold bubble) and iced coffee

Part1 \Iced coffee-made using hot extraction/

Ice coffee refers to cold coffee that is quickly extracted with hot water and then added with ice or cooled rapidly. It takes about 2- 3 minutes to make.

Advantages: Convenient and fast

Disadvantages: taste easily due to melting ice so that flavor weakened

Part 2 \Cold-extracted coffee (cold brew) Coffee-made using cold extraction/

Cold Brew Coffee is definitely the hottest drink keyword in the world this summer. Cold Brew concept is similar to cold tea, is a large amount of coffee powder directly soaked in cold water below 5 degrees C, long-term low-temperature coffee powder extraction coffee, about 8 - 12 hours, also known as iced coffee.

Refrigerate for a few hours, filter out excess fat, and bottle. This cold brewing method will amplify the various flavors and aromas of coffee, reduce acidity, and make the flavor cleaner and purer. Cold Brew coffee is characterized by the more ice the better to drink, without diluting and adding ice cubes. The United States is more popular to add equal proportions of coconut water, which can drink a purer coffee sweet taste.

Dripo accompanying cup can be used for cold brew coffee or iced drop coffee, only need to prepare ice water, coffee powder. One coffee powder, two pellet filter paper, three poured ice water can start making!

Advantages: Since they have not been brewed with boiling hot water, cold water at low temperatures will not force out the impurities and bitterness of coffee beans, so they prefer to use Cold Brew method to brew coffee. This method of drinking not only tastes fresher and sweeter, but also tastes smoother because the sour taste and bitterness are relatively reduced.

Cons: Due to the long contact time between water and coffee powder, the coffee in Cold Brew contains the strongest caffeine and is suitable for drinking at the moment when it is most necessary to maintain a high degree of sobriety.

Part 3 \Cold drip coffee /

Coffee that uses drops of cold water to extract flavor substances from coffee powder at a constant rate takes about 4- 8 hours, depending on the size of the equipment. The flavor of the coffee extracted varies according to factors such as roasting degree, water volume, water temperature, droplet speed, coffee grinding thickness, etc.

Advantages: cold water drip filtration, coffee 100% saturated wet, extracted coffee taste smooth and not sour, do not hurt the stomach, the most suitable coffee beans for iced coffee is nothing more than deep-roasted mantelin and fresh taste Ye Jia Xue Fei (Ethiopia).

Disadvantages: Need to master the drip rate, with 10 seconds seven drops of slow drip filtration, water and coffee powder have a long time to fuse, so coffee taste is more saturated; if the drip time is too fast, the taste is too light, and at the same time will produce stagnant water overflow, on the contrary, too slow will make coffee fermentation, produce sour and wine.

How to extract iced coffee

Are you ready for a real cold coffee this summer? Just prepare an ice drip maker, your favorite coffee, ice cubes, and patience. Follow these steps to have the so-called goddess of iced coffee in the coffee world

① Basic principles

The key to making iced coffee lies in "cold" and "slow". The ice water in the container at the top of the equipment is controlled by the valve to soak the coffee powder drop by drop. The coffee liquid is filtered once and gradually collected in the pot at the bottom. The whole extraction process takes about half a day.

② How to extract

③ extraction secret

Water powder ratio: The ratio of coffee powder to ice is about 1:10--12, which can be determined according to personal preference.

Grinding: It is recommended to grind the coffee powder to a fine level to increase the contact area between the coffee powder and the water.

Bean selection: recommend a more balanced taste of deep-roasted coffee beans mantinin, or with fruit aroma of yejia sherfie (Ethiopia) and Costa Rica.

#The main taste of light baked beans is the brightness of fruit acid and the aroma of flowers and plants. The beans represent Ethiopia. The beans with fragrant flowers and plants should be enjoyed immediately after ice drops. It is not suitable to wait for fermentation, because there may be wine fragrance after fermentation but there is no fragrance of flowers and plants.

#Deep-baked beans drink strong pure taste, can be used mantinin, mamba, Pacific drift, ice drops if drinking immediately usually bitter and no characteristics, it is recommended to wait for fermentation for 24-48 hours, will appear fermentation interesting taste, feel like wine, and the color is much darker than just drop good, lingering, rich taste.

Water speed:

It is better to drip slowly at about 1 drop per 2 seconds. Before dripping, the coffee powder should be completely soaked to avoid channeling, so that the water droplets cannot pass through all the coffee powder evenly.

Controlling the drip flow rate is an important part of making iced coffee. If the drip flow rate is too fast, the extraction will be insufficient, and the coffee will be very weak and have no aroma. Conversely, if the flow rate is too slow, it will allow coffee fermentation, resulting in sour or alcoholic taste. (But some people like this sour and alcoholic taste, so there will be cold brew coffee).

As for cold foam, ice or ice drops, which flavor is better?

In fact, iced coffee is to reduce the temperature of hot coffee, in the taste is far inferior to cold bubble and ice drop, cold bubble coffee and ice drop coffee are extracted with cold water coffee, compared with hot water extraction coffee, can retain the flavor and aroma of coffee to the greatest extent, at the same time soften the sour feeling and bitter taste, because cold water brewing coffee is not easy to oxidize, it can also inhibit the appearance of sour taste. (Note: The acidic fats in coffee are not easily dissolved in cold water.)
