Tips for the extraction of chilled, cold bubbles and ice droplets
The difference between ice, cold foam and ice drops
Made by thermal extraction
Ice coffee refers to cold coffee that is quickly extracted with hot water and then added with ice or cooled rapidly. It takes about 2 to 3 minutes to make.
Made by cold extraction
Cold Brew refers to coffee extracted by long-term cold steeping of coffee powder in cold water below 5 ° C, which takes about 8 - 12 hours. Also known as iced coffee.
Water-drip coffee refers to coffee that uses drops of cold water at a constant rate to extract flavor substances from coffee powder, which takes about 4 to 8 hours, depending on the size of the equipment.
It should be noted here that iced coffee is to lower the temperature of hot coffee, which is far less delicious than cold bubbles and ice drops.
Cold coffee and ice coffee are coffee extracted with cold water, compared to coffee extracted with hot water, can retain the flavor and aroma of coffee to the greatest extent, while softening the sour feeling and bitterness, because cold coffee brewing is not easy to oxidize, it can also inhibit the appearance of sour taste. The acidic fats in coffee are not easily dissolved in cold water.

Extraction of iced coffee
① Basic principles
The key to making iced coffee lies in "cold" and "slow". The ice water in the container at the top of the equipment is controlled by the valve to soak the coffee powder drop by drop. The coffee liquid is filtered once and gradually collected in the pot at the bottom. The whole extraction process takes about half a day.
② Extraction secret
Water powder ratio: The ratio of coffee powder to ice is about 1:10~12, which can be determined according to personal preference.
Grinding: It is recommended to grind the coffee powder to a fine level to increase the contact area between the coffee powder and the water.
Bean selection: recommend a more balanced taste of deep-roasted coffee beans.
Water speed: 2 drops in 3 seconds (40 drops per minute) is the best slow filtration.
So the question is, what does the device for making ice drops look like?
In fact, as long as it contains the following four elements, it can be called an ice drip pot.
① A container that holds water and ice cubes and can adjust the speed of water droplets.
2. Containers for coffee powder.
③ Filter: Paper, cloth or metal can be used.
4. Containers for coffee solution.

The baking degree determines the taste spectrum towards deep roasting, shallow roasting, moderately roasted coffee beans.
Coffee taste spectrum consists of "smell spectrum" and "taste spectrum"; the former directs dry and wet fragrance, while the latter refers to water-soluble taste. The aroma of "odor spectrum" is appreciated by the sense of smell before and after the nose, and the liquefaction taste of "taste spectrum" is captured by the sense of taste. The "smell" and "taste" of coffee often vary with variety, altitude, soil and water, producing area, post-preparation, extraction and roasting degree, but
