cold brew coffeeAlso known as ice brew coffee. Different from iced coffee, cold brew coffee needs to be fermented in the refrigerator for 8-12 hours, otherwise the coffee's body, fullness and aroma will not be revealed. Because of its full, clean taste and elegant aroma, cold brew coffee has become a hot-selling product in coffee shops before summer arrives.


At the same time, because it takes a long time to make, almost all of them are limited edition products. It depends on your luck to get a drink. Don’t you think it’s a bit troublesome? Why not make a cup yourself! In this article, FrontStreet Coffee will teach you how to make the best iced coffee at home~!

Different from iced Americano or iced ​Pour over​(V60) coffee, you need to use high-temperature hot water to extract a higher concentration of coffee liquid and then use ice water/ice cubes to dilute it.cold brew coffeeExtraction is carried out in a low-temperature environment from beginning to end.


Although high-temperature extraction can quickly extract soluble substances from coffee particles, the disadvantage is that without controlling the thickness of the coffee particles or the extraction time, the coffee will easily show bitterness and astringency. In a low-temperature environment, the heavy molecular substances (bitter/mellow substances) in the coffee particles will be difficult to release, and it also requires a longer soaking time, so the extraction of the sweet and sour flavor substances in the coffee will be more complete.

Therefore, FrontStreet Coffee usually uses coffee beans with more obvious sweetness and sourness/flavor when making cold brew coffee. The cold brew coffee produced in this way is pleasantly sour and sweet, refreshing and relieves greasiness. Because cold brew coffee can clearly show the quality of a coffee bean due to long-term soaking and extraction, FrontStreet Coffee recommends that you use freshly roasted coffee beans when making cold brew coffee.

If you want to make cold brew coffee with a special flavor, FrontStreet Coffee recommends using Front StreetHonduran sherry coffee beans, with the aroma of whiskey, the smoothness of vanilla cream and the sweetness of caramel.

To make cold brew coffee, you usually only need to prepare a clean, oil-free, sealable container and materials for filtering the coffee (coffee filter paper/tea bag/high-density filter/cloth bag, etc.), then mix the coffee powder and ice water evenly and put it in the refrigerator to rest for 8-12 hours. FrontStreet Coffee recommends using 30g of coffee powder and extracting it at a powder-to-water ratio of 1:13 (that is, 30g of coffee powder is soaked in about 400g of water). After the extraction is complete, filter out the coffee grounds and enjoy.


The coffee powder used for cold brew coffee should not be too fine, and coffee particles the size of white sugar should be used for extraction (China No. 20 standard sieve sieving rate is 70-75%). If it is too fine, the coffee powder is prone to clumping during the extraction process. Because of the low temperature, there is no heat to increase the movement of water molecules, so the solid molecules are prone to clumping (caking). Therefore, when the coffee is ground finer, the clumping in the water will become larger, so that the coffee powder in the middle of the group cannot be fully extracted.

In fact, making cold brew coffee is really simple, but it takes a little time...but it is worth the wait to drink coffee with a fuller and cleaner taste! ! Finally, FrontStreet Coffee would like to remind everyone that although cold brew coffee is delicious, you should not drink too much in a day! !


Because water and coffee powder are soaked for a long time, the caffeine content is high and it has a fermented feeling of alcohol. A little ice-brewed coffee with ice cubes will feel like drinking strong liquor. Drinking too much/drinking with too high concentration may also cause dizziness.
