There are over 100 distinct species of coffee plants. But the most popular two among coffee manufacturers are Coffea Arabica and Coffea Canephora, which respectively produce the Arabica and Robusta beans.

Robusta beans are more circular and tend to be darker in shade, whereas Arabica beans have an elongated shape and a wavy central split, they’re also slightly larger in size.

Robusta beans are generally described as bitter, harsh, with grainy notes of burnt rubber, and an aftertaste of peanuts. Arabica beans on the other hand are said to be smooth, floral, acidic, sweet, with flavors of chocolate and hints of fruits.

Robusta vs Arabica caffeine content

As a result, Arabica beans are more commonly used to produce high-quality coffee products. Whereas Robusta’s intense caffeine content makes it more prominent in espresso pods and instant coffees, it also serves as a filler agent to decrease the price of Arabica.

That said, a highly caffeinated drink also depends on how it was made.

That said, you can’t mention high caffeine without talking about the massive effect brewing has on your coffee.

Strongest coffee roast?

Roasting is quite a complex process during which beans undergo heat treatments as well as physical and chemical changes that will define the color and flavor of the beverage.
Does it affect the beans’ caffeine content? Not really.

Dark roast vs Light roast caffeine content:

Contrary to popular belief, caffeine levels remain intact after roasting. Mostly due to the fact that the compound is very stable, even at +400°F temperatures. So basically, dark roast and light roast coffee contain pretty much the same amount of caffeine.
There’s a small catch though…
The roasting process has a direct effect on total mass loss. As in, the longer you roast coffee, the more of its density is lost.
Put simply, if you measure out your coffee using a scoop, light roast coffee will have slightly more caffeine because the beans are denser. But technically speaking, you’ve just scooped out more coffee mass.
So, the secret for more caffeine punch? Add more coffee.
Which brings us back to…

Which coffee brewing method has the most caffeine?

Brewing techniques make a big difference in providing that unique caffeine buzz because many factors can influence the final result.

Key brewing factors:

Grind size:

A finer grind size will provide more surface area for caffeine extraction; this guarantees improved results. Espresso for instance, which contains more caffeine per volume than drip coffee, uses a very fine grind size.

Water temperature:

Colder water significantly reduces caffeine extraction, while water that is too hot might cause substantial loss of quality.

Brew time:

Longer time means higher caffeine levels. An example here is Turkish coffee brew, which relies on soaking coffee ground into hot water for extended periods of time. Ultimately, a serving size of 59ml (2 fl. Oz) worth of Turkish coffee will contain around 60mg of caffeine.

Brewing gear:

A machine dwell time, its settings, and performance will also have a significant impact on your beverage.

Bean variety:

Are coffee beans 100% Robusta, Arabica, or a mixture of the two?

The Takeaway – Since there are so many parameters at play, acting on one will definitely require adjusting other factors to get the best mixture of flavor and caffeine.
For instance, if water is at room temperature, setting the brew time anywhere between 12 to 24 hours will produce a less acidic, highly caffeinated jolt of java. Aka the popular cold-brewed coffee.

Strongest coffee brewing method?

Taking into account the above factors, it is quite difficult to estimate the exact amount of caffeine content per drink as the smallest of variations can intervene with the brewing process.

Coffee typeCaffeine content
Percolated (1 Cup of 8 fl. Oz)64-272mg
Turkish (1 Cup 8 fl. Oz)160-240mg
Espresso shot50-77mg
Drip or Filter (1 Cup 8 fl. Oz)115-175mg
French press (1 Cup 8 fl. Oz)80-135mg
Cold Brew (2 Cups 8 fl. Oz)~200 mg
Caffeine content per coffee type

Keep this in mind though, it generally depends on the standard serving size for each drink.

For example, Espresso is highly concentrated in caffeine, but it’s also only served in tiny sizes. This is why a cup of drip coffee will contain more caffeine.

That said, start stacking up Espresso shots, and that’s when it really hits.

Brewing coffee for maximum caffeine?

If you want to make the most out of your coffee beans, you might also want to try the below hacks:

  • Slightly increase coffee to water ratio.
  • Match grind size to the requirements of your brewing machine:

Coarse grind for French press and percolator.

Medium grind for a drip coffee maker.

Fine to extra-fine grind for Espresso and Turkish.

  • Consider letting your coffee brew a little bit longer.

Also, as mentioned before, it’s important to take into consideration how various brewing parameters interact with each other depending on your gear, type of beans…

Not to forget!

Each individual has a unique metabolism, so what works best for you might have an entirely different effect on the next person.

From bean variety to the smallest variation in its brewing process. there are many ways one can get that purely caffeinated coffee cup completely wrong.
