If you want to make delicious iced drip coffee, Front Street believes that the following three points are indispensable:
Choose floral and fruity coffee beans:
Since cold brew coffee is coffee extracted at low temperature and for a long time, more small molecular substances in the coffee beans such as floral aroma and fruit acid are extracted, while large molecular substances such as tannic acid and other bitter substances are difficult to extract. In addition, after the extraction is completed, it needs to go through 12 hours of low-temperature refrigeration fermentation. Therefore, when choosing ice-drip coffee beans, Front Street generally chooses some coffee beans with rich fruit flavor, clear floral aroma, or with a sense of fermentation:

The first one can choose Front Street Mozart, which has the flavors of raisin, pineapple, and orange;

The second recommendation is to buy Front Street Xizhao, which has the sweet aroma of passion fruit, grape, and apricot;

The third recommendation is Front Street Kenya. The ice-drip coffee made has the juice flavor of ebony, snow pear and Bolin.
Master the grinding thickness of coffee powder:Since the water temperature used in ice-drip coffee is relatively low, the rate of material exchange is greatly slowed down. Therefore, in addition to extending the extraction time, it is also necessary to finer the grinding degree of the coffee beans, try to increase the contact area between the water and the surface of the coffee powder particles, and extract as much of the ideal flavor substances in the coffee powder as possible.

If the coffee powder particles are too fine, too many flavor substances will be extracted, including some unpleasant bitterness; if the coffee powder particles are too thick, the flavor will eventually be unclear and the taste will be too light. Front Street has found through many tests that the grinding degree of using Chinese standard No. 20 sieve with a passing rate of 85% is more ideal.

The trickling filtration speed should not be too fast:Generally, we first calculate the extraction parameters. Using a powder-to-liquid ratio of 1:10, 60 grams of coffee extracts 600g of coffee liquid. The ratio of the ice-water mixture is 1:1. The flow rate of the valve is controlled at 7 drops every 10 seconds. The production of ice drops in Front Street is usually completed within 6-8 hours. Usually the ratio of ice drops is 1:10-1:12, and you can adjust it according to your own taste.
The specific steps for making ice-drip coffee at FrontStreet Coffee are as follows:
Amount of powder: 60 grams
Pink to water ratio: 1:10
Grinding degree: Chinese standard No. 20 screen pass rate 85%
Time: 6-8 hours

1. Take out the powder cup, moisten the bottom and lay the filter paper so that the filter paper sticks tightly
2. Pour 60 grams of ground coffee powder into the powder cup, smooth the surface and lay it with round filter paper
3. Pour a small amount of ice water or room temperature water to moisten the coffee powder
4. Add an appropriate amount of ice-water mixture into the water container
5. Adjust the regulating valve to a speed of 5 drops of water in 10 seconds
6. After the extraction is completed, put the coffee liquid into a sealable container and place it in the refrigerator to refrigerate for one night before drinking.
