When you drink coffee every morning, have you ever wondered why coffee can refresh you?

Yes, it's because coffee contains caffeine, which awakens your brain, relieves fatigue and makes you feel refreshed.

When you are extremely tired and need a cup of coffee to pick you up, do you know which kind of coffee has the best pick-me-up effect?

Coffee is not a soda or functional drink. The specific content of caffeine is marked on most soda or functional drinks, while coffee is different. origin, baking degree, single product or mix, coffee's own beans, brewing methods and other factors can affect the caffeine content of coffee.

Most of the caffeine content marked on the coffee package is estimated, which is not only accurate, but can at least provide us with a reference. Today, let's take a look at which caffeine is the highest in drip coffee, cold extract coffee and espresso.

Espresso

Many people believe that a cup of espresso contains more caffeine than a cup of filtered coffee. Actually, this is wrong.

Espresso contains about 64 milligrams of caffeine per ounce (30 milliliters). Take Starbucks coffee as an example. Starbucks espresso contains 75 milligrams of caffeine.

In other words, espresso contains 64-75 milligrams per ounce (30 milliliters), so a single cup of espresso contains less caffeine than a single cup of drip coffee.

In addition, espresso is usually diluted with water, milk or cream to make American or milk-based coffee. A large latte macchiato contains 20 ounces (591 milliliters) and contains three cups of espresso, with a caffeine content of 225 milligrams. By contrast, a cup of drip coffee of the same size contains almost twice as much caffeine.

Drip filter coffee

The caffeine content of dripping coffee depends on the brewing method, size and concentration.

An 8-ounce (237 ml) cup of drip-filtered coffee contains between 95 and 163 milligrams of caffeine, which is 2-5 times that of a regular soda (34 milligrams for Coca-Cola and 69 milligrams for Pepsi).

In addition, the caffeine content of the same drip coffee bought in different places is also different.

For example, the 14-ounce (414ml) drip coffee sold by Dunkin' Donuts contains 210mg of caffeine, while the 24-ounce (710ml) super-large cup contains 359mg.

By contrast, Starbucks sells 12 ounces (355 milliliters) of drip coffee with 260 milligrams of caffeine, while large cups of 20 ounces (591 milliliters) contain 415 milligrams, depending on the roasting method. According to records, Starbucks' large cup of drip coffee can even contain 475 milligrams of caffeine.

The U.S. Food and Drug Administration (FDA) specifically stated in 2012 that Starbucks' large cup of drip coffee contained more caffeine than the average American's daily caffeine intake (300mg that year). As people drink more and more coffee, this figure has now been adjusted to 400-450 milligrams.

Of course, there are always some people who forget the rules of the country. Death Wish Coffee claims that their 12-ounce (355ml) drip coffee contains 660mg of caffeine; what's more, Black Insomnia Coffee coffee of the same size has a caffeine content of 702mg!

This is twice the national standard for caffeine intake! Why is there so much caffeine in their coffee? It turned out that instead of using 100% Arabica coffee, the two cafes used a mixture of robusta coffee. You know, Robuska coffee contains much more caffeine than Arabica coffee.

Cold extracted coffee

Cold coffee is completely different. Although hot water can extract more caffeine, it is extremely high in caffeine because the proportion of cold-extracted coffee (gouache) is extremely low, usually between 1:4 and 1:8 (1:15 to 1:25 for drip coffee).

But when drinking, we usually dilute it with water or ice cubes, so the caffeine content of cold-extracted coffee does not send us to the sky.

But even so, it is important to note that cold coffee contains much more caffeine than your usual drip filter coffee.

For example, Stumptown's 10.5oz (311ml) cold extract coffee contains 279mg of caffeine, while 11oz (325ml) nitrogen cold extract coffee contains 330mg.

Chameleon's 32-ounce (946ml) cold-extracted espresso contains 2160 milligrams of caffeine, while open-bottle cold-extracted coffee contains 10oz (296ml) caffeine. Espresso is not for direct drinking. You need to dilute it with 1:1 water or milk.

Starbucks cold coffee contains much less caffeine, with 16 ounces (473 milliliters) containing only 200 milligrams.
