If you are a person who has drunk cold coffee, then you will surely linger in that unique smooth taste and "pure" quality. Why is cold coffee so popular? How is it different from ordinary iced coffee? Let's have a cup of coffee in front of this article. What is cold coffee?

The difference between cold coffee and iced coffee

Many people distinguish cold coffee from iced coffee because we understand that iced coffee is extracted with hot water and then added with ice or chilled to change the coffee from hot to iced coffee.

The biggest difference of cold-extracted coffee is the coffee liquid obtained by low-temperature extraction of ice water used throughout the process. Due to the cold extraction of low temperature, coffee can well avoid the release of some bitter substances, thus making the flavor of coffee chic, unique and mild.

Flavor characteristics of Cold extracted Coffee

Low temperature extraction and long extraction time are the two main characteristics of cold extraction coffee, and they are also the two main differences between cold extraction coffee and high temperature extraction coffee. High-temperature extraction of coffee is through hot water extraction of coffee beans, the temperature between 82-95 ℃, the time is generally no more than 3 minutes.

The cold coffee itself can fully reflect the subtle taste characteristics of coffee, because the acidity of coffee is mild, the taste is sweet, the taste is bright, and the taste is soft, Qianjie coffee thinks that cold coffee can show the flavor characteristics of a boutique coffee bean producing area.

What kind of coffee beans are suitable for cold extraction?

As low-temperature extraction is not easy to release mellow substances, making cold-extracted coffee is more suitable for the use of light-to-medium freshly roasted coffee beans with sweet and sour taste. Qianjie Coffee believes that only freshly roasted coffee beans will have a richer flavor and aroma, so all the coffee beans ordered by friends are issued within five days after the roasting is completed.

For those of you who like the strong sour taste, you can try "Qianjie Coffee-Huakui Coffee beans". This is a kind of sun-treated coffee beans from Humbera buku processing plant in Sidamo, Ethiopia. Growing at high altitude gives this coffee bean a very good level. After making cold extract coffee, it will show the sour and sweet of berries, the sweetness of honey and the sweetness of black tea.

If you like the flavor of flowers and fruits, but not too sour, you can try "Front Street Coffee-Flower Butterfly Coffee beans" ~ this is a mixed variety of rose summer and Kaddura Kaduai from Panama. The rose variety brings floral fruit notes to this coffee bean, and the Kaddura Kaduai variety brings soft acidity and mellow thickness to this coffee. After being made into cold extract coffee, it will show the fragrance of white flowers, soft acidity like citrus, sweetness like caramel and sweet like green tea.

If you like something that is not sour and has a special taste, you can try "Qianjie Coffee-Shirley Coffee beans". This is a coffee bean fermented in a whisky barrel from Moca Manor in Honduras. This coffee bean is characterized by low acidity, mellowness and wine aroma. When made into cold extract coffee, it shows whisky aroma, vanilla cream smoothness and hazelnut caramel sweetness.

How is a cold coffee made for one person?

First prepare a clean, oil-free glass bottle with a 200ml lid that can be sealed.

Then weigh 20g to make cold-extracted coffee beans, and medium grinding / white granulated sugar size (China 20 standard screen screening rate of 75%).

Then put it in a glass bottle and add 1:10 room temperature / ice water. Fully stir to ensure that the coffee particles are in contact with water, sealed into the refrigerator cold extraction area for 8-12 hours, do not need to shake, static soaking.

After soaking, use a filtering tool to filter the coffee / coffee filter paper to filter the coffee grounds, and you can start tasting!

Preservation time of cold-extracted coffee

Some friends have heard that cold-extracted coffee can be kept for 2-3 weeks, but Qianjie coffee is not recommended to be kept for so long. When the cold-extracted coffee is sealed and preserved after the extraction is over and the coffee grounds are filtered, it is recommended to finish drinking within 72 hours.

Some cold-extracted coffee made at home will be mixed with different meat and vegetables in the family refrigerator, even if sealed, but it is difficult to avoid the invasion of bacteria, so remember to drink it as soon as possible after making cold-extracted coffee.
