The Origin and principle of Iced Coffee

Before introducing ice drop coffee, we must understand that brewing coffee is actually the use of water to release the aromatic substances contained in coffee powder, a process often called "extraction". 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.

So the ice drop coffee pot will be divided into three parts: the upper pot filled with ice water, the filter set with coffee powder, and the lower pot to receive the extracted coffee liquid. Sometimes in front of the pot, there will be a decorative snake-shaped glass tube, let the brown liquid winding down, it is very interesting.

When making ice drop coffee, take out 600~800CC 's ice drop coffee at the ratio of 1 cup, 6 grams, 8 grams, that is, 100g coffee powder, in addition to adjusting the shade according to your own taste, you should also consider that it will be slightly lighter when served with ice cubes. In addition, before the formal drip, the coffee powder should be completely infiltrated with cold water, so as not to produce channel phenomenon and cause extraction failure.

Like mellow wine, it takes time to wait patiently if you want to brew a good ice drop of coffee. It takes several hours to extract. You have to store the coffee liquid in a sealed glass bottle and in the refrigerator for one to three days. This slightly fermented taste makes the coffee sweeter and as thick as whiskey.
