As we all know, the reason why coffee can have a refreshing effect is due to caffeine. Caffeine is a central nervous system stimulant commonly found in coffee, tea, and chocolate. When we drink beverages containing caffeine, caffeine is quickly absorbed into the bloodstream, crosses the blood-brain barrier, enters the brain, and plays a role in the brain.
The main reason why we feel tired or drowsy is that a molecule called adenosine in the body binds to receptors. When caffeine preemptively binds to adenosine receptors, it inhibits the transmission of fatigue signals and keeps the brain awake. Additionally, caffeine promotes the release of the neurotransmitters dopamine and norepinephrine, which improve our focus and concentration. This is why after drinking coffee, we feel like we have been injected with chicken blood, and we can work more efficiently.
Because of this, we generally have two ways to refresh ourselves: one is to drink a few more cups, and the other is to choose coffee drinks with higher caffeine content, such as cold brew and ice drip. For reference, the caffeine of cold brew coffee (a cup of 20g powder/200ml coffee liquid) is about 140mg, while the caffeine of a cup of American coffee is 100mg. Cold brew is obviously more refreshing.
So what is cold brew coffee?
Cold brew coffee, the English name is Cold Brew Coffee. Cold brew coffee is made by grinding coffee beans into powder and soaking them in cold water for more than 8 hours. If you want a richer body, the time can be extended to 24-48 hours. After steeping, we just need to filter out the coffee grounds and taste it.
Front Street Coffee (FrontStreet Coffee) and how to make cold brew coffee?
If you want to drink cold brew coffee but don’t want to go out to buy it, then FrontStreet Coffee is here to teach you how to make cold brew coffee at home. Cold brew coffee is a very easy way to master. FrontStreet Coffee's cold brew coffee is based on 50 grams of coffee powder. In terms of grinding selection, because the temperature of the water in contact with the coffee powder is lower than that of ordinary Pour over(V60) coffee, a slightly finer scale is selected than Pour over(V60) coffee, that is, the No. 20 standard sieve pass rate is 85%. Put the coffee powder into a glass bottle, then add 400 ml of room temperature water and 200 grams of hard ice cubes (a total of 600 grams of ice-water mixture) into the bottle. The ratio of powder to water is 1:12. Then use a stirring stick to stir the coffee powder and water evenly, seal it and place it in the refrigerator to refrigerate.
Put it in the refrigerator for 12 to 24 hours and use filter paper to filter out the coffee grounds to get clean coffee liquid. Then use a clean sealed bottle to put the coffee liquid in and refrigerate it for about 4 hours before drinking.
Here, FrontStreet Coffee needs to tell everyone that cold brew coffee does not taste better the longer it is brewed. Whether it tastes good or not is a very subjective matter. Some people like fresh and clean coffee, while others like strong, fermented coffee. These all vary from person to person.
For those who like a heavier fermentation, FrontStreet Coffee recommends that the extraction time can be slightly longer. As the time is extended, the fermentation of the coffee liquid will become heavier, but the concentration of the coffee will be richer and the taste will be more complex. If you feel that the coffee liquid is too strong when drinking, you can add two ice cubes. As the ice cubes melt, the concentration of the coffee liquid will also decrease. Finally, people often ask Front Street: What coffee beans are suitable for cold brew. Judging from the production experience of Front Street, if you want delicious cold brew coffee, you can give priority to medium-light roasted coffee beans. If you prefer floral aroma, I recommend Front Street Panama Gesha Coffee, which is one of the most expensive coffees in the world;
If you like fresh and sour coffee, we recommend the Front Street Ethiopian Oiran coffee beans, which have the flavor of black tea and berries, or the juice-filled Front Street cherry tomatoes; of course, there are also Front Street Hija with passion fruit and fermented flavors.
