Since Starbucks launched cold coffee in 2015, it has been reported that the turnover of cold drinks has increased by 20%. The concept of cold coffee is actually due to New Orleans Coffee, which was first used by Blue bottle Coffee and Stumptown in the early days. Starbucks is actually a rising star.

However, it is Starbucks that brings cold coffee to the mass market. Many coffee suppliers, such as Dunkin Donuts, serve cold coffee almost all the year round. Because cold coffee is easy to store, more and more forms of cold coffee are available on the market.

Olive Strand, a reporter for the New York Times, wrote in June 2017 that the United States is about to become the country of cold coffee, and it is true today.

Although cold extraction is becoming more and more popular and very attractive, consumers still have a lot of doubts about it. What's the difference between cold coffee and iced coffee? Why is cold extraction more expensive?

Coffee is a very complex drink. This article takes you to five common problems with cold-extracted coffee:

1. What's the difference between cold extract and iced coffee?

Simply put, iced coffee is cooled by hot flushing and presented as a cold drink. You can mix the hot coffee directly with ice cubes, or refrigerate for a few hours before drinking it. Unfortunately, both types of iced coffee have their drawbacks. The former will dilute your coffee, while the latter will never have a fresh flavor after a few hours.

However, cold-extracted coffee is made by soaking coarse ground coffee beans in water at room temperature for 6 to 12 hours. This produces coffee mixed with cold water or milk.

People who like cold coffee say it tastes smoother than iced coffee, and people who don't like sour taste will find it easier to taste than hot coffee. (it is even reported that the acidity of cold-extracted coffee is 67% less than that of hot coffee.)

two。 Why is cold extraction so expensive?

Hot coffee takes only a few minutes from grinding to making, while cold coffee needs to be made and stored in advance. The store needs to mix the coarse ground coffee with normal water for at least six hours, and once the cold extract coffee is sold out, it is impossible to continue to supply it on the same day because there is not enough time to make a new cold extract.

In the unpredictable service industry, this is a relatively troublesome problem. In hot weather, a large number of unexpected guests may come to the store like locusts crossing the border. If the shop is not large, the cold extract that may be made in advance will soon be swept away, leaving many people without cold coffee. Therefore, the store will set the price of cold coffee higher than hot coffee, because this is a limited supply of drinks.

3. Does cold extract have more caffeine than hot coffee?

Caffeine content usually depends on the situation.

When you brew coffee in hot water, you extract more caffeine, Anna Brones wrote in The Kitchn: "Cold-extracted coffee is usually made with a higher powder-to-water ratio, which is usually higher than 2: 2.5 times, which means making the same amount of cold extract, which is stronger than coffee made by traditional methods. "

To make matters more complicated, cold extracts are often diluted with the same amount of water or milk, Brones added: "this reduces the amount of caffeine per cc drink." Cold-extracted coffee usually contains less caffeine than the same amount of hot coffee, but many factors affect caffeine content, including the origin of coffee beans, formula structure, as well as their roasting method, grinding thickness and brewing method.

4. Can I be cold at home by myself?

Of course, and it's very simple. Here's a zero-failure cold extraction formula for you:

Four portions of the formula-

Utensils: use a pressure kettle or filter with a filter cloth

Methods: 200g beans were ground, injected with 1 liter of cold water, soaked in the refrigerator for 12-16 hours, then directly filtered coffee or filter cloth, and then mixed with the same amount of water or milk.

No matter how busy you are, just finish it in advance, and then you can enjoy a delicious cold extract in a few seconds.

5. How long can the cold extract be stored in the refrigerator?

If you make your own cold extract, the author recommends drinking it 24-48 hours. (but the translator suggests that you can keep the cold extract in the refrigerator for a week or two, and it will add a cold flavor, but cover or seal the container containing the cold extractive. avoid absorbing the odor of the refrigerator). If you are buying a ready-made cold extract, there is a different shelf life, which should be based on the advice of the merchant.
