Is cold iced coffee as strong as traditional coffee? This is actually a very interesting question.

The proportion of cold extracted coffee is usually between 1:5 and 1:10. Let's take a chestnut. There is a kind of cold-extracted coffee. Baristas use 50g of coffee beans, grind them into medium-coarse particles, pour them into a container, add 250g-500g water, and then store them overnight at low temperatures according to the formula. The time is about 16-22 hours. After the cold-extracted coffee is made, filter out the coffee liquid, and then add water, milk or ice to dilute and adjust.

Therefore, the amount of caffeine in the cold-extracted coffee you drink depends on the concentration of the original solution and how much raw liquid you have added to the finished coffee. So it's hard to infer exactly how much caffeine a cup of cold coffee contains.

Let's take the recent rich star dad as an example. according to officials, star dad has 165 milligrams of caffeine for every 16 ounces of regular iced coffee, while the same amount of cold coffee contains 200 milligrams of caffeine. Thus it can be seen that cold extract coffee wins.

But the way they make it is different: iced coffee starts with a double concentration of hot coffee and then poured on ice (of course, it dilutes caffeine after freezing). On the other hand, cold-extracted coffee is soaked in a small amount of cold water for a long time. In this case, the cold coffee is more full-bodied.

Take Starbucks as an example, let's take a look at the characteristics of the two approaches:

Iced coffee:

Simple and traditional, coffee extracted at high temperature is poured on ice

The temperature is low but the alcohol is full, and as the ice melts, the taste will become thinner and thinner.

But the production time is short, convenient and fast.

Cold extract coffee:

The concentration is higher and the caffeine content is higher than ordinary iced coffee.

Compared with traditional coffee, cold extracted coffee tastes softer

The production method is equally fast, but it takes a long time.

So, which one do you like better?

If you are allergic to caffeine or low caffeine, maybe cold coffee will disappoint you, but then again, who doesn't fall in love with coffee because of both flavor and caffeine?
