The original meaning of cold brew is that under low temperature conditions, small molecular substances that tend to be aromatic and sour are more easily released in cold water, so the coffee tastes light and tastes sweet and sour. In addition, because it is not restricted by equipment or location, cold brew can be said to be coffee that is readily available to people. As long as you have the raw materials, bottles, water, and a refrigerator, you can easily achieve caffeine freedom at home.
Making cold brew coffee is actually very simple. As long as we choose the right coffee beans that suit our preferences, and then use the right parameters, we can brew delicious cold brew coffee with our eyes closed. After all, this extraction method just mixes ground coffee powder and water, puts it in the refrigerator and is basically complete.
The main reason why many friends are unable to brew delicious cold brew coffee is that they do not grasp the parameters correctly. If we want to make a delicious cup of cold brew coffee, we must master three key parameters: grinding, ratio, and time.
First, let’s choose a coffee bean that suits our preferences.
If the cold brew coffee you want to drink is full of juice, sweet and sour, then it is best to choose coffee beans with a light ~ medium roasting degree. The first choice is Front Street Huaoi, which uses sun-drying treatment, has a refreshing taste and low bitterness, and can drink elegant flavors of berries, citrus, and flowers;
If you are looking for a fermented taste, you can try Front Street Xizhao. This is a Pour over(V60) product from Colombia. It is processed by double anaerobic sun-drying. The degree of fermentation is heavier than that of sun-drying. Therefore, it has rich ripe tropical fruit aroma. After being soaked in cold brew, it shows characteristics like fruit wine;
If you want to drink some iced coffee with a heavier taste, buy the medium to dark roasted Front Street Queen's Manor. If you don't want any acidity, just choose the dark roasted Front Street PWN Golden Mandheling coffee beans, which are rich and mellow.
Grinding degree of coffee powder: The thickness of the grinding degree determines the total surface area of the coffee powder. When the total surface area of the coffee powder is larger, water can penetrate into the interior faster and bring out the flavor substances in the coffee powder. For immersion extraction that stands still for a long time, fine grinding helps dissolve flavor substances, so we can adjust the grinding degree of coffee powder to be finer than Pour over(V60) coffee.
The powder-to-water ratio of coffee: The powder-to-water ratio refers to the ratio of coffee powder to water, which determines the concentration of coffee. The reason why the cold brew coffee brewed by many friends is weak is because the ratio of powder to water is too low, and too much water is injected, which dilutes the concentration of the coffee too much.
In fact, we can make the cold brew coffee a little thicker, because if the concentration is high, we can dilute it by adding ice, but if the concentration is low...emmmm, can the juice be reduced over high heat? This obviously doesn't work. Therefore, we would rather use a relatively high ratio of powder to water in the early stage to make the coffee more concentrated, rather than using too much water and causing the coffee to be too weak.
Coffee steeping time: The last thing to note is the coffee steeping time. Because cold brewing requires "bubbing" the substances in the coffee powder through soaking, the length of time determines how much of the substances are dissolved. If we want to make the coffee as strong as possible, it is best to extend the steeping time appropriately.
After we are familiar with the above three points, we can enter the process of making cold brew coffee!
How to make cold brew coffee?
For specific bean selection, you can go here to learn about "How to quickly find the coffee beans you like?" ”, Front Street chose “Mozart”, which has recently become a favorite among store customers, as the bean used for this brewing. The cold brew coffee steeped in it will have a very full juice flavor, with flavors such as grapes, berries, wine, and a slightly purple floral aroma similar to lavender.
The production parameters of Mozart cold brew are as follows:
Amount of powder used: 80g (you can adjust it according to your own drinking amount)
Grinding scale: 9 scale of Ek43, 85% sieving rate of No. 20 mesh, fine sugar grinding
Pink to water ratio: 1:10
Soaking time: 12 hours
Remember to prepare a sealable container! After we grind the coffee beans into powder, the first thing to do is to pour the coffee powder into the container!
Then inject the target amount of water! Because Front Street uses 80g of coffee powder, 800ml of room temperature water will be poured in.
After pouring the water, stir it to speed up the moistening of the coffee powder!
The bottle can then be sealed and placed in the refrigerator.
When the soaking time is reached, we can putTake out the coffee, filter out the coffee grounds with filter paper, and enjoy delicious cold brew coffee! (If the brew is thicker, remember to add ice to dilute it~)
