What is ice drop coffee?

Ice drop coffee, to put it simply, uses "low temperature" and "slow drop" to extract coffee.

Brewing coffee usually uses hot water to quickly extract and dissolve the odor molecules in coffee cells, while ice drop coffee uses time instead of temperature, dripping in coffee powder with ice water below 5 degrees Celsius, slowly dissolving out the flavor of coffee, and dripping out the final extract bit by bit.

It can take a short time to make a cup of coffee, such as 25 seconds for Espresso, 1 minute for siphon pot and 3 minutes for hand brewing coffee. However, iced coffee often takes several hours to wait, usually about 8 to 12 hours, depending on the individual taste and the type of coffee beans.

So the question is, how do you make ice drop coffee?

Selection of POINT 1 Coffee beans

Iced coffee is 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, it will cause the iced coffee to be too strong and bitter.

The thickness of POINT 2 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 3murmur5 on a bean grinder can be used for ice drops, 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.

POINT 3 coffee powder to ice water golden ratio

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 the ice water to maintain the ice water temperature.

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

Uniform extraction of POINT 4 has skimming steps!

Before the formal ice drop, you can use a little normal temperature water (for example, 40g coffee powder using water 80ml), 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.

The matters needing attention when making ice drop coffee are...

The best dripping speed of POINT 1

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 regulating valve so that the dripping speed of ice water can be maintained at 7 drops per 10 seconds. If the dripping speed is too fast, it will cause flooding and blockage; and if the dripping speed is too slow, it will prolong the overall dripping time.

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 5murmur7 drops / 10 seconds.

POINT 2 has a 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 and ferment, and the time is judged according to the beans used. Shallow roasted beans can be refrigerated and fermented for 1 day, while deep-roasted beans have to be refrigerated and fermented for 4-5 days. And according to coffee beans may produce wine, berry flavor.

The taste of iced coffee will be stronger!

Introduce the commonly used ice drop coffee formula of Qianjie coffee, 30 grams of red wine treatment [Hartmann] + 30 grams of sun [Sakuran], powder: water: ice is 1:5:5, the time is about 8 hours, after dripping, put it in the refrigerator overnight, drink according to the personal taste to add ice. It tastes full of fermented wine with a little acidity.
