There is a growing demand for iced coffee. Ice droplets and ice brew are the best ways to retain the flavor of iced coffee, so what's the difference between the two?

At a time when household ice cups are not as common as they are now, if you want to have a cup of cold iced coffee, you can choose to go to a coffee shop to buy "ice drop coffee." now many household ice drop kettles that ordinary families can afford appear on the market, allowing people to make ice drops at a lower and lower price, while at the same time being able to DIY themselves.

However, in recent years, there has been an upsurge of "ice-brewed coffee". Starting from the concept of cold-brewed tea, soak the coffee powder in an ideal proportion of room temperature water, seal the container and put it in the refrigerator for about 6 to 12 hours. Take it out of the refrigerator and filter out the coffee liquid with a sieve (or coffee filter paper). You can have a cup of delicious iced coffee. It's super simple! And you can control the proportion and the amount of coffee you want, but you should pay attention to the ice brew because it has been soaked in water for a long time, so the caffeine content will be higher.

Although ice-brewed coffee is convenient, is there any flavor difference between ice-brewed coffee and iced coffee?

If the extraction time is longer, the aroma will be lost more. Assuming that the extraction time and gouache ratio of ice droplet and ice brew are the same, the extraction rate of ice brew will theoretically be higher than that of ice droplet. This is because ice brew uses room temperature water at the beginning of soaking, and does not let the temperature drop to 0 degrees when it is sent to the refrigerator. Compared with ice droplets, ice water drips into coffee powder and the temperature is kept at about 0 degrees Celsius. The extraction rate is also relatively low.

In terms of flavor, the difference in extraction rate between ice brew and ice drop will make the acidity of ice drop higher than that of ice brew coffee; visually, because the fine coffee powder will leak out from the powder bag of ice brew, the color of ice brew will be more cloudy. Ice droplets have filter paper at the beginning, the color will be more thorough, if some friends mind ice brewing, you might as well use fine sieve or filter paper to filter the brewed coffee will have a more refreshing taste. Compared with hot coffee, because the extraction rate of ice-brewed coffee is much lower, bitterness and other bad flavors are more difficult to extract, which is why some people like ice-brewed coffee!
