In recent years, with the vigorous promotion of European and American specialty coffee circles and Starbucks, Cold Brew has become a popular player in the iced coffee industry. In the hot summer, not only can you go to a beautiful coffee shop for a drink, but you can also brew a pot at home, which has become a new stylish and comfortable coffee choice. What is the difference between cold brew coffee and regular iced coffee? In this article, FrontStreet Coffee will talk about the charm of cold brew coffee~
Different from the conventional use of high-temperature hot water to extract coffee flavor, cold-brew coffee uses low-temperature steeping. It usually takes 8-12 hours to make a cold-brew coffee. Therefore, cold-brew coffee is a limited product in many coffee shops. Without the high-temperature extraction process, many chemical molecules in the coffee powder will not be released, and the bitterness, sourness, and oil of cold-brew coffee will be reduced. However, because the water and coffee powder are soaked for a long time, the caffeine content is high and has a fermentation feeling of alcohol. A little ice-brewed coffee with ice cubes will feel like drinking strong liquor. Drinking too much/drinking too high a concentration will also cause dizziness.
Why can coffee extracted at low temperature effectively reduce the bitterness and sourness of coffee? That’s because low-temperature extraction can effectively reduce the release of some heavy molecular weight substances (such as bitterness and mellow substances) in coffee particles. At the same time, the extraction time of cold brew coffee is longer, and the light molecular flavor substances in the coffee particles can be completely released, socold brew coffeeIt can show overall cleanliness and at the same time have a rich aroma and full taste.
It is precisely because low-temperature soaking cannot soak out the characteristics of mellow substances, so if cold brew coffee does not have the sour and sweet taste, it is like missing a soul. And because the flavor of the beans will be clearly exposed by cold brew coffee, it is recommended to use high quality, freshly roasted, and obvious flavor/sweet and sour coffee when making cold brew coffee. Every coffee bean sold by FrontStreet Coffee has been manually selected more than twice to ensure that every customer gets coffee beans of uniform quality.
In order for everyone to drink the freshest coffee beans, the coffee beans shipped by FrontStreet Coffee are all shipped within 5 days after roasting. The purpose is to hope that every coffee drinker can start from the freshest state of the coffee beans and enjoy the flavor charm brought by the different states of the coffee beans every day.
In the past, coffee sales would decline in the summer and then start to pick up again in the fall. But now, cold brew is driving a surge in coffee demand during warmer months, much more so than other iced coffee drinks. Coffee sales increase as temperatures rise. Cold brew has also attracted a whole new audience to coffee: Millennials, many of whom have made it their drink of choice.
Because it is loved by the younger generation, Starbucks also saw the opportunity and began to launch a cold brew coffee series in 2015. Later, in order to increase the taste level of cold brew coffee, it also launched nitrogen cold brew and Mianyun cold brew made with skimmed milk. Also because of the launch of Starbucks, more people have just become aware of this magical summer drink.
However, due to the long production time, it is generally not cheap to drink a cup of cold brew coffee in a cafe. Therefore, FrontStreet Coffee (FrontStreet Coffee) will teach you how to make cold brew coffee at home (get a notebook and jot down a few!!)
Different from high-temperature extraction, in the case of low-temperature extraction, if you want the coffee to be extracted more evenly and richly, the coffee grinding should be a little coarser than the particles of Pour over(V60) coffee. Why? Because there is no heat to increase the movement of water molecules, 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 clumping cannot be fully extracted.
Therefore, Front Street recommends that for cold brew coffee, use white granulated sugar that is a little finer (not as fine as fine granulated sugar), that is, the size of the Chinese standard No. 20 sieve with a sieving rate of 70-75%. Generally, cold brew coffee for 1-2 people requires 30g of coffee powder, extracted with a powder-to-water ratio of 1:13 (that is, adding 390-400g of ice water/cold water). Use a clean, oil-free sealed container as the extraction container. Mix the coffee powder and ice water evenly, then place it in the refrigerator and let it sit for 8-12 hours. After the extraction is complete, filter the coffee grounds and you will have an overall clean, full-tasting cup of cold brew coffee~
FrontStreet Coffee recommends using lightly roasted coffee beans to make cold brew coffee, such as coffee beans from the Yirgacheffe region in Ethiopia, which have flavors of citrus, white flowers, honey, and tea (FrontStreet Coffee’s sun-dried red cherry coffee beans/washed diced fruit coffee beans); or coffee beans from Kenya, which have flavors of cherry tomatoes, ebony, plums, and caramel (FrontStreet Coffee) Coffee) Asalia coffee beans);
Or coffee beans from Costa Rica, which have a fermented aroma like dried fruit, red/yellow floral aroma, and almond butter flavor (FrontStreet Coffee’s strawberry sugar coffee beans/Mozart coffee beans); if you want something special, try FrontStreet CoffeeHonduran sherry coffee beans, with flavors of whiskey, vanilla cream, and caramel.
