The invention of ice coffee, originally is to extend the shelf life of coffee, ice water to extract coffee, will not be like hot water brewing extract coffee oil ester, so add good refrigeration conditions can be stored to a month is not a problem, and after 3 days of ripening, more can make coffee more glycol, but ice water extraction coffee takes a long time, the general well-known ice coffee is naturally extracted with ice water, Many coffee shops also use ice to melt the extract for more than 24 hours, so the caffeine concentration will be higher.
In addition to the use of ice water, in fact, when making iced coffee at home, you can also use boiling water at 30 ° C to replace ice water, the time can be shortened, extracted by boiling water at 30 ° C in a drop per second, immediately refrigerated, mellow and flavor than ice water extraction is even worse, at the same time can be stored for a long time, glycol flavor will not deteriorate

It can be extracted with water at room temperature of 30 ° C to increase extraction efficiency, better flavor, shorter extraction time, and refrigerated in refrigerator.
Use mature coffee, use freshly roasted coffee with carbon dioxide, raised coffee powder layer, will expand to the drip port, affecting the water
The extraction efficiency can be increased by soaking the coffee powder layer first and then extracting it by drip filtration.
Uniform extraction, on the coffee powder layer, place a circular filter paper, so that water droplets can be more dispersed to the surrounding coffee powder layer, so that all coffee powder layers can be extracted evenly, not only concentrated in the center of the powder layer
Stable cold storage conditions, the extraction of coffee into a glass jar, placed in the lower refrigerator or thawing chamber
Rich and mellow ice drop coffee, from the refrigerator can be taken out immediately drinking, quite convenient, if you feel too strong, you can add ice or ice water dilution, but also does not reduce the flavor of glycol, if not diluted 1/3 ice drop coffee, 2/3 ice milk, made of latte, add a little syrup, is delicious
