The degree of extraction is usually different because of the temperature, contact time and grinding thickness of the water. the mild flavor is usually insufficient extraction, while the bitter taste of excessive extraction is easy to cause tongue discomfort.

It is said that ice drop coffee was invented by the Dutch, so it is also known as Dutch drip coffee. Unlike other brewing methods that require hot water, ice drop coffee is extracted with ice water and extracted at a low temperature. It takes longer to dissolve the aromatic substances in the coffee. Therefore, the use of a chemical experiment-like eyedropper, let the ice water drop by drop, slowly infiltrate the coffee powder, the common traditional ice drop coffee maker, the speed of water drop can be controlled.
