Cold Brew CoffeeAlso known as iced brewed coffee. Unlike iced drip coffee, cold brew coffee needs to be steeped in the refrigerator for 8-12 hours, otherwise the coffee's body, richness, and aroma will not be brought out. Because of its full, clean mouthfeel and elegant aroma, cold brew coffee becomes a hot-selling product in coffee shops every summer.

At the same time, due to the long preparation time, it is almost always a limited product, and being able to drink a cup depends on luck. Do you find it a bit troublesome? Why not make one yourself! In this article, Front Street Coffee (FrontStreet Coffee) will teach everyone how to make the king of iced coffee at home~!

Unlike iced Americano or iced pour-over coffee, which require first extracting a high-concentration coffee liquid with hot water and then diluting it with ice water/ice cubes,cold brew coffeeis extracted in a low-temperature environment from beginning to end.

Although high-temperature extraction can quickly extract the soluble substances in coffee grounds, its drawback is that if the coarseness of the coffee grounds or the extraction time is not well controlled, the coffee can easily show bitterness and astringency. In a low-temperature environment, the heavy molecular substances in coffee grounds (bitter/body substances) are difficult to release, and a longer soaking time is also required, so the extraction of the sweet and sour flavor substances in the coffee is more complete.

Therefore, when making cold brew coffee, Front Street Coffee (FrontStreet Coffee) usually uses coffee beans with more obvious sweet and sour notes/more obvious flavors for extraction, so that the cold brew coffee produced is pleasantly sweet and sour, refreshing and greasy-cutting. Because it is a long soaking extraction, cold brew coffee can clearly express the quality of a coffee bean, so Front Street Coffee (FrontStreet Coffee) recommends using freshly roasted coffee beans when making cold brew coffee.

Every bag of coffee beans sold by Front Street Coffee (FrontStreet Coffee) is shipped within 5 days of the roast date, ensuring that the coffee beans reach every friend in their best condition. Before roasting and after roasting is completed, Front Street Coffee (FrontStreet Coffee) has dedicated personnel to sort the coffee beans to avoid defective beans affecting the expression of coffee flavor.

To make a refreshing cold brew coffee, Front Street Coffee (FrontStreet Coffee) recommends using Front Street'sFlower Queen coffee beansfrom the Sidama region of Ethiopia, which have full berry sweetness and acidity, alluring red floral aromas, and a faint fruity fermentation aroma. To make a full-bodied cold brew coffee, Front Street Coffee (FrontStreet Coffee) recommends using Front Street'sCosta Rica Strawberry Candy coffee beans, which have the aroma of strawberry hard candy, the sweetness and acidity of strawberries, and the sweet fragrance of candied fruit. To make a cold brew coffee with a special flavor, Front Street Coffee (FrontStreet Coffee) recommends using Front Street'sHonduras Sherry coffee beans, which have whiskey aromas, 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 bags/high-density filter mesh/cloth bags, etc. are all fine), then mix the coffee grounds and ice water evenly, put it in the refrigerator, and let it sit for 8-12 hours. Front Street Coffee (FrontStreet Coffee) recommends using 30g of coffee grounds and extracting at a coffee-to-water ratio of 1:13 (that is, soaking 30g of coffee grounds in about 400g of water). After extraction is complete, filter out the coffee grounds and it is ready to taste.

The coffee grounds used for cold brew coffee should not be too fine. Use coffee particles about the size of granulated sugar for extraction (passing rate of 70-75% through the Chinese No. 20 standard sieve). If they are too fine, the coffee grounds are prone to clumping and sticking together during extraction. Because of the low temperature, there is no heat to increase the movement of water molecules, so solid molecules are prone to clumping (forming lumps). Therefore, the finer the coffee is ground, the greater the clumping in the water, so that the coffee grounds in the middle of the clump cannot be fully extracted.

Actually, making cold brew coffee is really very simple, it just takes a bit long... But being able to drink coffee with a fuller, cleaner mouthfeel is still very much worth the wait!! Finally, Front Street Coffee (FrontStreet Coffee) wants to remind everyone that although cold brew coffee is delicious, you should not drink too much of it in one day!!

Because the water and coffee grounds are soaked together for a long time, the caffeine content is relatively high, and it carries an alcoholic fermentation feel. A little iced brewed coffee plus ice cubes can feel like drinking strong liquor, and drinking too much or at too high a concentration can also cause dizziness.
