How much caffeine is there in a cup of coffee?

According to the National Coffee Association (NCA), a typical cup of drip coffee (8 ounces) contains about 65-120mg of caffeine. Caffeine content varies so widely that it is difficult to assess how much caffeine you consume from typical coffee. But why such a big change?

Do not be too technical, several factors should be considered when brewing coffee, including coffee type, grinding degree, brewing time, extraction time, water temperature, baking degree, blending and other factors, all factors have an important impact on the final extraction of caffeine.

Now, if we look at the caffeine in a typical cup of drip coffee and espresso, these numbers are 92.5mg and 40.0mg, respectively, but these are averages.

As you can clearly see, about 92.5 mg of drip coffee contains more caffeine than espresso (40 mg)-how much? The average is about 2.3 times!

So we say-filtered coffee has more caffeine than espresso!

No, the right way to compare espresso with drops of coffee is to compare the caffeine concentration of the two drinks per ounce.

In the case of dripping coffee, we need to distribute 65-120 mg caffeine to its size (8 oz), about 8.1-15 mg / oz caffeine concentration. This means that for every ounce of coffee liquid, we expect about 8.1 to 15 milligrams of caffeine.

In espresso, even if we start with about 1 ounce of caffeine, all of this caffeine contains only 1 ounce of liquid, or 30-50 mg / oz in numerical terms.

In other words, in an ounce of espresso solution, we get about 30-50 milligrams of caffeine.

What's the point?

Although we can conclude that drip coffee contains at least twice as much caffeine as espresso, we need to consider that this is due to a larger milliliter.

In short, we can sum up as follows:

In terms of liquid volume, espresso has less caffeine because it is much smaller.

But in terms of volume percentage, espresso contains more caffeine than coffee because the 1oz coffee is more soluble.

Conclusion: espresso vs drip filter coffee.

Is espresso really more caffeinated than a drop of coffee?

So once again the answer depends on your point of view. If we see this problem from a:

Cup size > filter coffee has more caffeine.

Volume percentage-> espresso has more caffeine

The following picture shows the caffeine you absorb when you buy espresso (~ 1 oz) and standard coffee (8 oz). In other words, if you drink espresso, you will absorb about 30-50 mg of caffeine and 65-120 mg of filtered coffee. Of course, these are just averages, but you get the point.

* caffeine content in coffee drops (8 oz) vs espresso (1 oz) *

65-120mg (BP) (8-15/1oz) (VP)

30-50mg (bp) (30-50/1oz) (VP)

Bp-- cup volume, vp-- volume percentage

Why do people believe that espresso contains more caffeine than filtered coffee?

So part of the reason for this belief is that caffeine itself has a strong bitter taste. Because the beans used in espresso are more roasted, this produces higher concentrations of "bitter" molecules.

The logical "connection" seems to be correct-but in fact it is not.

The bitter compounds produced by deeper baking are not due to caffeine but are bitter compounds produced during the Maillard reaction.

The concentration of caffeine (per serving) in espresso is much lower, which means you can drink 5 to 10 servings of espresso a day without excessive shaking. Try a 12-ounce cup of dripping coffee and you may end up visiting the hospital because of excessive caffeine levels in the circulatory system.

Unfortunately, it is very difficult to regulate caffeine in coffee drinks because there are many variables to consider, including:

Cup size-4 oz, 5 oz, 12 oz or 24 oz?

Blending-many roasters create their own coffee mixes, each with subtle differences

Coffee bean variety-is it a blend of 100% Arabica coffee, Robusta or both?

Degree of grinding-is coffee made of fine grinding, ultra-fine grinding, roughness, etc.? (hand screen can be used to measure crushing particle size)

Water temperature-coffee brewed in the temperature range of 195-205 °F is recommended.

Milk-whether milk is added because it dilutes caffeine

Other-equipment model, residence time, etc.

All these factors make the calculation of caffeine in coffee drinks a real challenge. It is hoped that through the implementation of industry standards through trade organizations, we can also create more standard coffee cups.
