How long is the ice drop coffee? how long is the shelf life of ice drop coffee? what is the difference in the taste description of ice drop coffee?

Ice drop coffee is made by melting pure ice into small water droplets, dripping the coffee essence extracted by freshly ground coffee powder at a uniform speed, and then refrigerating for eight hours and then fermenting naturally. The taste of ice drop coffee is mellow, sweet and sour, cold and delicious, and it is sure to be on the list in the hot summer days in front of the street.

How to make iced coffee at home?

After many friends became infatuated with the taste of ice drop coffee, they got the ice drop equipment to operate at home, but encountered all kinds of doubts. Qianjie first takes store products as the standard to demonstrate how to make ice drop coffee and answer these questions.

At present, there are a wide variety of coffee utensils on the market, and the device of the ice drip pot is still three main parts: the upper pot of ice water (connected to a valve that can adjust the flow rate of water droplets), the filter cup of coffee powder, and the lower pot of coffee liquid. When you come to the front street store, you will see Tiamo HG2713, which will be filled with a circular drainage glass tube. You can choose according to your own needs and budget.

The grinding degree of ice drop coffee in Qianjie has a screening rate of 80-85% in China's No. 20 standard sieve and an EK43s scale of 10 in stores. We all know that coffee powder is too coarse, coffee flavor will be light, grinding too fine, easy to form blockage can not normally drain the situation and then make the coffee bitter, so it is very important to choose the degree of grinding.

This time Qianjie is made of refreshing Asaria beans from Kenya, and the extraction rate is low at low temperatures, so Qianjie baristas recommend a finer grinding than hand flushing, where the standard sieve pass rate is 85%.

The velocity of ice droplets is the same as that of hand flushing, but the velocity of ice droplets is calculated as the number of drops per second. The slower the velocity is, the longer the total time is required, and it is easy to be extracted. Qianjie usually uses 7 drops every 10 seconds to extract, and everyone can adjust the flow rate according to their own preferences. The powder-to-liquid ratio is 1:10, because the ice drop coffee from Qianjie will be diluted with ice, so it will use a higher concentration. If it is made at home, it can be extracted with 1, 10, 1, 12.

In the front street, the ice droplets are ground with 60g coffee beans into powder, put a round filter paper in the powder cup, pour the coffee powder, and finally spread a piece of filter paper on the surface and then wet the coffee powder with water, which can save the time of dripping filtration. at the same time avoid uneven extraction. Fill the upper pot with a mixture of ice and water, that is, ice and water at 1:1, for a total of 600g coffee extract. Finally, pour the filtered coffee liquid into an airtight container and store it in the refrigerator for 12 hours before drinking. Qianjie is usually filtered during the day, can be refrigerated in the evening, and can be tasted with ice the next day.

How long can I keep the iced coffee?

The freshly dripped coffee liquid has a weak aroma and a thin taste, so it needs to be stored in a low temperature environment for sealed fermentation to make the coffee flavor substances cleaner, mellow and full, and enhance the aroma and sweetness of the coffee, as well as the wine flavor. With the longer the storage time, the higher the degree of fermentation, the ice droplets of more than five days have a negative effect on the taste, so it is not the longer the better. Qianjie suggests that it is best to store in the refrigerator for 5 days.

In addition, when we open the back cap of the bottle, outside bacteria are easy to invade, causing the coffee to deteriorate and should not be drunk in order to ensure the flavor and health of the coffee. The ice drop coffee produced in the front street store only has a three-day appreciation period.

What are the coffee beans suitable for ice drops?

With regard to the choice of coffee beans, Qianjie believes that coffee beans with different processing methods or roasting degrees can be made according to their preferences, as long as the coffee beans are in the best taste period (2 months). The extraction characteristics of ice drop coffee can highlight the aroma of wine, fruit fermentation and fruit aroma in the coffee. If you don't know which coffee beans to choose, you can refer to several types of coffee listed in front of the street.
