What is black coffee? Why is Icedrop Coffee expensive? How to make iced coffee? What is the difference from American?

Black coffee refers to pure coffee that adds nothing but water. American, hand-brewed, ice drops, etc. are all members of black coffee. Because they do not add any ingredients such as milk, cream, sugar, etc. that can affect the taste of coffee, the taste of coffee can be displayed more purely. Then I believe it will not be difficult for everyone to find that when ice drops into this black coffee, the price is often high. If a coffee shop sells ice drops, its price will likely be higher than that of American and hand-washed. For example, Qianjie Store is a good example. Even if the same beans are used to make it, the price of ice drops will be higher than that of American and hand-washed.

So this made many customers and friends curious: "Why is the price of the same coffee bean produced with ice drops higher than that of other categories? "

There are two reasons! The first reason is that compared with other black coffees, the production of ice drop coffee takes longer and the process is more cumbersome!

Longer production time and more cumbersome production process No matter what kind of black coffee it is, its production requires the use of water as a solvent to dissolve the flavor substances in the coffee. The temperature of the water will determine the rate of dissolution! In the tweet "What degree of water is the best to make coffee?" Qianjie mentioned that the kinetic energy of water molecules is affected by temperature. When the water temperature is higher, the faster the water dissolves flavor substances., and vice versa. Most black coffees, such as hand-brewed and American-style, are extracted using hot water, so they do not take long to make and can be finished in a few minutes. Ice-drop coffee is completely different. It is a cold-extracted coffee that uses ice water at a very low temperature for extraction. However, due to the low water temperature, the extraction efficiency is very low, so the extraction time it requires often lasts as long as several hours.

At this time, a professional ice drip pot is generally used (or not needed), and the control of the drip speed valve is used to allow the ice water to slowly drip in the form of water droplets, thereby extending the overall extraction time and allowing the coffee to obtain a complete extraction. Extraction. Take the production of ice drops in Qianjie as an example: Qianjie generally uses 60g of coffee powder when making ice drops coffee, and then the parameter is a powder-to-liquid ratio of 1:10. The drip frequency of ice water is about 7 to 8 drops in 10 seconds. Under such parameters, the entire extraction process usually takes about 5 to 8 hours.

When the extraction is completed, the ice drop coffee cannot be drunk immediately, because it still needs to be fermented to develop its flavor. So we need to pour the dripped iced coffee into a sealed bottle and place it in the refrigerator for "low-temperature cooking." Usually Qianjie will refrigerate and ferment it for more than 8 hours to ensure that the ice drops can ferment a unique aroma/fermentation feeling. When the fermentation is complete, we can officially start enjoying the delicious taste of Ice-Drip coffee!

I believe it is not difficult for you to see from the ice drop making shared on Qianjie that the process of making ice drop coffee is very cumbersome and time-consuming. A rough calculation shows that it takes more than 13 hours to make a 600ml pot of ice-drop coffee, which is still a relatively fast speed. The standard for ice drop production on Qianjie is 200ml of ice drop coffee with 1 to 2 ice cubes. That is to say, only 3 cups of 600ml coffee made after "hard work" can be produced. Whether it's hand-brewed coffee or American coffee, they only take about ten minutes to make 3 cups. In contrast, the time cost of making ice-drop coffee is dozens of times more.

Higher material costs But more often, ice drop coffee is more expensive mainly because of the material cost. Still in the above example, Qianjie used 60g of coffee powder to make 600ml of ice drop coffee liquid, but in the end, only 3 cups could be produced. If this 60g of coffee powder is placed on hand-brewed coffee, it can produce 4 cups, because the standard for hand-brewed coffee is to brew a pot of 15g of powder.

Because a cup of iced drop coffee uses more powder and costs more, it usually sells for a higher price than other black coffees. To sum up, everyone knows why Ice-Drip coffee sells more expensive most of the time. Not only because it costs more materials, but also because it takes longer to produce ~
