Ice drop coffee parameters suggest that you can make delicious and sweet ice drop coffee at home in only 6 steps.

1. Selection of coffee beans

Ice droplets are a way to concentrate and extract coffee, which is suitable for medium-roasted or medium-to-deep-roasted coffee beans; if you use deep-roasted or French-roasted coffee beans, the iced coffee will be too strong and bitter.

2. The thickness of coffee powder

The fineness of coffee powder suitable for ice drops is equivalent to that of hand-brewed coffee, as long as the coffee powder ground by 3: 5 on the bean grinder can be used for ice droplets, and its thickness is equivalent to Taiwan sugar 2 sugar. If it is too fine, it will cause the ice drop to pass through the powder layer more slowly and prolong the extraction time of the ice drop, and it will cause the coffee from the ice drop to be too strong; if it is too thick, the flow speed is too fast, and the coffee from the ice drop will be too light.

3. The golden ratio of coffee powder to ice water

The ratio of coffee powder to ice water can be adjusted according to your taste, about 1: 10: 1: 12, and a little ice cubes (about 30 g) can be added to ice water to maintain the ice water temperature.

If you use fresh coffee powder that is easy to absorb water (ground coffee beans within 7 days after baking), it is recommended to reduce the coffee powder by 5 to 10g so that the coffee powder is about 8 points full of the container, so as to prevent the coffee from expanding and filling out of the powder filling tank.

4. Uniform extraction to avoid channel

Before the formal ice drop, you can use a little normal temperature water (for example, 600g coffee powder using water 1200ml), rinse the coffee powder 3 times along the clock or in the same direction from the center of the coffee powder surface, so that the whole coffee powder can be soaked, so that the subsequent ice water drips evenly, thus making the coffee extraction more evenly; in addition, put filter paper or filter mesh on the surface of coffee powder, have the same effect.

5. Set the best dripping speed

Put the coffee powder into the middle filling tank, put the ice water into the upper pot holder, and then match the meter to adjust the water control valve to keep the dripping speed of ice water at 5 / 7 drops per 10 seconds. If the dripping speed is too fast, it will cause flooding and blockage; while the dripping speed is too slow, it will prolong the overall ice dripping time. The whole journey takes about 6-8 hours.

If the ice drip machine has no water control valve, as long as the whole ice water is used and placed in the refrigerator, the hole design will automatically carry out 5 / 7 drops / 10 seconds.

6. Better flavor.

If you want to make the taste more mellow, you can use plastic wrap to cover the container containing ice drop coffee, or pour it into a washed glass bottle, refrigerate for 2-3 days to ferment, and according to the coffee beans may produce wine, berry flavor.
