Cold-extracted coffee is produced by slow extraction after mixing coffee powder and ice water in a certain proportion. The coffee produced by cold extraction process has a low sense of acidity, low temperature and long contact with coffee powder, so that only small molecular flavor substances, such as flower and fruit flavor, are extracted, while those with larger molecules, such as smoky flavor, are difficult to extract.

What's the difference between iced coffee and cold coffee?

To put it simply, iced coffee is made by cooling hot coffee, while cold-extracted coffee is extracted at a low temperature without heating. And because cold-extracted coffee needs to be extracted at low temperature for a long time (generally speaking, it takes 12-24 hours), the price of cold-extracted coffee sold outside is generally on the high side (take Starbucks as an example, the price of iced coffee Grande is 110yuan and the price of cold-extracted coffee is 140yuan for the same size). Low-temperature extraction also makes cold-extracted coffee have a unique flavor, and different extraction methods of the same beans can produce completely different flavors. Even because the oil of coffee is less extracted by low temperature extraction, ice-drop cold-extracted coffee can generally be preserved for two weeks, and as it is preserved for a long time, the coffee will taste more attractive after fermentation, and it can even taste like wine!

1. Grind the coffee beans into powder and pour them into a container.

2. Add 20 grams of coffee powder to the sharing pot, add about 350 milliliters of water, and stir well.

Tips: the ratio of coffee powder to water is 1:15-1:20, adjusted according to preference.

3. The plastic film is sealed and refrigerated for more than 12 hours. 24 hours is the best. The cold storage temperature should be controlled at 0-5 degrees as much as possible.

4. take it out after cold storage and filter with boiling filter paper or filter cloth.

Method two

1. Put 20g coffee bean powder into a non-woven filter bag (or gauze) and seal it.

2. Put the filter bag into the sealing cup and add water.

3. Press the filter bag for a few seconds, let the powder absorb water, cover the lid, and put it in the refrigerator.

4. Remove the filter bag and drink it.

If the store is used, you can also purchase special cold extraction appliances, such as HARIO, TODDY and so on.

Preservation of cold extract

Cold extracted coffee for more than a week is not recommended. Sterilized sealed cans can be used for convenient storage. You can also consider freezing the cold-extracted coffee into an ice case, and blending syrup and other excipients is another vitality.

Of course, coffee shops at home and abroad in order to promote this drink, with fashionable outer bottle packaging, have stolen the limelight in instagram and American TV series. While improving appearance, it also makes storage more convenient.
