What should I do with cold coffee? Cold coffee tastes healthier?

The claim that cold coffee has lower caffeine content or higher antioxidant activity is actually a false myth. Because the temperature is more conducive to the solubility of many molecules, and can change the structure of coffee powder, so that many small molecules that were tightly grasped by coffee can be released. No matter what kind of coffee, as long as the right amount of drinking can be leisure and health.

How do you make cold coffee? Qianjie Coffee takes [Costa Rican Mozart] as an example to explain to you!

-required raw materials-

◆ beans: we use single beans of front street coffee, Costa Rican Mozart, cold extracted coffee beans: water: ice = 1:5:5

◆ finely ground coffee powder. Rough grinding is the key to making cold extracted coffee.

◆ a jar. Plastic or glass cans are fine, preferably with a lid. If you want to take two photos, use the rest of the jam jar or the French kettle is a good choice.

◆ ice water. Use filtered water or bottled mineral water.

◆ filter. If you are not using a kettle, you need to find a piece of coffee filter paper or pasteurized cotton cloth.

-production steps-

1. Prepare

◆ poured the coffee powder into the jar.

◆ slowly pour ice water and gently stir to make sure the coffee powder is completely soaked.

◆ close the lid. If there is no lid, seal it with cotton cloth.

2. Soak

Soak in the refrigerator for 12 hours, don't worry!

3. Filtering

◆ if you are using a French kettle, gently lower the pressure bar, filter the coffee powder, and then pour out the coffee.

◆ if it is not a kettle, you need to filter the coffee powder with coarse cotton cloth or filter paper.

◆ had better filter twice and then pour out the coffee powder. (there is no need to waste the leftover coffee grounds, they can be made into fertilizers or refrigerator deodorants, etc.) do not throw coffee grounds away, the use of coffee grounds is simply wonderful, rising posture!

4. Tasting

1. 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 requires low-temperature extraction 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, so low-temperature extraction gives cold-extracted coffee a unique flavor. different extraction methods of the same beans can produce completely different flavors, even because low-temperature extraction is less likely to extract coffee oils. Therefore, cold coffee can generally be preserved for two weeks, and as it is preserved for a long time, the coffee will taste more charming after fermentation, and it can even taste like wine.

Cold-extracted coffee is extracted at low temperature for a long time to preserve the original flavor of coffee!

two。 Is there any difference in the flavor of the cold coffee?

The extraction process of coffee is generally extracted at high temperature, which will make the tannic acid in the coffee decompose into pyrouric acid, resulting in a sense of bitterness and acid. However, cold-extracted coffee can be reduced by about 67% in this respect than high-temperature extracted coffee because of low-temperature extraction, and at low temperature, water has been in contact with coffee powder for a long time, so that only small flavor substances, such as flowers and fruits, are extracted. on the other hand, large flavor substances such as smoking and roasting are difficult to be extracted from the extraction area, so cold extracted coffee can drink more of the flavor of coffee beans. It tastes smoother, the hierarchical flavor is obvious, and it is obviously sweet.

Cold-extracted ice-drop coffee can show that the original flavor of beans is obvious, and the flavor is smooth and sweet.

3. I heard that cold coffee tastes healthier?

Because the coffee is not extracted at high temperature, the impurities in the coffee are extracted less, so for friends who often drink coffee to cause gastrointestinal discomfort, you can try cold-extracted coffee. He is a little more friendly to the stomach than the coffee extracted at high temperature. In addition, cold extraction is generally slightly lower in caffeine (for example, Starbucks Grande iced coffee contains 225mg, cold extract contains 200mg).

More in line with the health needs of the coffee choice, more importantly, it is more delicious!

4. What's the difference between iced coffee and cold extract?

Ice droplets are also a kind of cold-extracted coffee, compared to Cold Brew directly put water and coffee powder together for 12 hours, ice droplets are extracted drop by drop, also known as Dutch coffee or Jingdu coffee. American barista champion Laila once said in an exclusive interview that it is more fragrant and more delicate and subtle than COLD BREW iced coffee (ICE-DRIP).
