A mug of coffee in the morning helps us wake up, to be more focused. That is actually the caffeine does.
In the United States, on average, a person consumes three and a half cups of coffee every day in various forms.
We are human. Every human is different. We all have different tastes, and different feelings about everything. For coffee, it’s also true.
For example, you and your very close friend go to a coffee shop regularly. There, you may have a very profound feeling for espresso. On the other hand, your very close friend may like a latte very much.
Now coming to the point, about the coffee caffeine content of a coffee cup.
While drinking, you both are consuming caffeine. But the amount of caffeine you are consuming is not the same. So, the effects of caffeine will also not be the same.
Let me explain with numbers. A regular shot of espresso (1.5 US fl. oz.) contains 77 mg of caffeine. If we calculate the ratio of caffeine, it is 51.3 mg per fluid ounce. At the same time, a regular latte, serving size of 16 US fl. oz. contains 154 mg of caffeine. The ratio is 9.6 mg per US fluid ounce. Again, Turkish coffee contains 25 mg/fl. oz. (See The Chart Blow)
Not only in coffee, but we also consume caffeine in other drinks like tea, energy drinks, soft drinks, etc. Coffee and tea are natural drinks that consist of caffeine. You might be getting a little surprise, the core ingredient of chocolate, cocoa, contains a good amount of caffeine.
Caffeine can be found naturally in coffee beans, tea leaves, cocoa beans, etc. Though the levels of caffeine are different. We focus on caffeine content in coffee only here. But as we drink tea, soft drinks, or energy drinks regularly, you can have a quick look-see on what drink has the highest caffeine content.
The amount of caffeine varies due to some important factors. Before we jump to the reasons, Let’s have a look at the coffee caffeine content chart.

Why Coffee Caffeine Content Levels Vary For In Different Types Of Coffee
Now, we have seen there is a huge difference in levels of caffeine in different types of coffee. The core influencer in this dissimilarity is believed to be the coffee beans. Besides, the roasting level of coffee beans, coffee brewing methods, and the number of coffee beans are also responsible for the differences. Let’s dig into them one by one.
Coffee Bean Types
Different types of coffee beans from different Coffea plants have different levels of caffeine. Coffee robusta contains more caffeine than coffee arabica.
If we go deeper, as they have many species, the amount of caffeine varies also on grounds bean of species.
In general, the caffeine content of Arabica beans is in the 0.8–1.4% range. Whereas, robusta contains 1.7–4%.
By nature, there are some species, basically, variations of arabica that contain a very low amount of caffeine. It happens because of the environment, soil, and other factors. These coffees are known as low-caffeine coffee.
Different coffee manufacturing companies produce coffee with different caffeine levels. If you wanna know more, you will get your answer here for which coffee brand has the highest caffeine content?
It’s a very common question asked, which roast of coffee has the highest caffeine content?
Well, the caffeine level decreases as the roasting level increases.
But there is a myth running about quite the opposite. ‘Dark roast contains more caffeine’.
This is completely wrong. The roasting process lowers the caffeine level.
Unroasted beans have the highest level of caffeine. After the first level of roasting, lighter roasted coffee contains a high level of caffeine.
When we get the dark roast, it has already passed two levels and is in the third level of the roasting process. Darker roasts contain a low level of caffeine.
Some modified dark roast like – Italian roast, and French roast contains very low caffeine.
Coffee Brewing Method
Caffeine very likely differs in how the coffee is prepared.
Like, a shot of espresso has a different level of caffeine than coffee americano.
Then again, the specialty of decaf coffee is having a very low amount of caffeine. Sometimes, doctors prescribe us to have decaf coffee for a particular scenario. A small heads up, Low caffeine and decaf coffee aren’t the same.
Amount Of Coffee Bean
Most of us usually drink coffee of regular strength. But some people like it mildly and some people strongly.
It can change depending on the situation too. For instance, you are feeling very sleepy. But you have very important work to finish.
Naturally, you will grab a coffee. Now, there is a good chance, you will add an extra amount of coffee beans with hot water to make it very strong. That will make you more focused, and more energetic.
For that, in a coffee shop, if you are having a shot of espresso or a double shot of espresso and want stronger strength, the barista will add more coffee beans. And that will increase the level of caffeine in your coffee.
Excepting these main reasons, there might be some minor reasons. It is believed that sometimes the serving size also influences the coffee caffeine content level.
Besides that, it also varies sometimes from coffee shop to coffee shop. People are quite curious about the famous coffee house chains, as we regularly go there. You may also wonder sometimes about what coffee has the most caffeine at Starbucks. The coffee caffeine content of Starbucks might deviate from the coffee caffeine content of Dunkin’ Donuts.
