The secret to good iced coffee

generally drink iced coffee if the coffee is brewed with hot water, it will take a while to brew and cool down, after adding ice will dilute the coffee concentration, if you do not want to drink ice diluted coffee, coffee brewed with hot water into the refrigerator can also drink the original coffee, the disadvantage is not durable, because the relationship between brewing with hot water, coffee oil ester, although filtered by filter paper, will still retain part of the oil ester, The general shelf life is only 2-3 days, after which it will be sour due to fermentation of oil esters.

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

Coffee: Guatemala Colombia Mantenin Sidamo Blend

Baking Degree: Medium Deep

Extraction equipment: Driver Ice Drop Kettle

Powder: 40 g

Water temperature: 30 degrees C

Drip rate: one drop per second

Powder/water ratio: 1:12. Infiltrate the powder layer slowly with 60 g of cold boiled water until the coffee drops to a few drops in the next pot. Add 420g of boiled water to the top pot and start dripping (about 8 minutes full).

Extraction time: about 100 minutes

For example, in ice water, drip in two seconds

Here are a few quick steps to make and preserve iced coffee

Disinfection and sterilization: Blanch the ice drip pot with hot water before starting ice dripping, or wipe the plastic pot with 75% medicinal alcohol to avoid coffee deterioration due to bacteria during refrigeration. Extraction also requires boiled cold water. If ice cubes are added, ice cubes should also be made of boiled cold water. Ice cubes older than 3 days should also be avoided.

Use medium fineness of grinding, general electric grinder about 3-3.5 scale can be

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

In order to maintain the flavor of coffee, it is recommended not to put the ice drip pot into the refrigerator extraction, because in a few hours of drip filtration process, the food flavor in the refrigerator will enter the coffee liquid, and iced coffee to be stored in the refrigerator for a week or longer, more need to be completely sealed, only the general metal lid of the glass jar to preserve iced coffee, or avoid the refrigerator flavor, so you can use a rubber lid of the oil vinegar special glass bottle to preserve coffee, Or drink the golden three wheat glass jar, clean and then disinfect with hot water, used to preserve iced coffee for a long time, iced coffee but there is no refrigerator smell, environmental protection and recycling applications
