Check out our guide that breaks down how we determined the variables of which coffee has the most caffeine
So Which Coffee has the most caffeine?
Types of coffee beans

When talking about coffee beans, you’ve probably heard about two main kinds: Arabica and Robusta. Arabica beans are often smoother and have a better taste, while Robusta beans can taste strong and bitter.
These beans are also sorted by how much caffeine they have. Robusta coffee beans contain more caffeine than Arabica coffee beans. Many instant coffees use Robusta beans, so if you want a stronger kick in your coffee, I suggest using Robusta beans.
If you look around the grocery store most coffee you see use robusta as well, due to the ease of farming these beans.
Did you know that the kind of coffee bean isn’t the only thing that affects how much caffeine is in your cup? There’s another factor that people often think about when it comes to caffeine – the type of roast.

Types of coffee roast

For some reason most people assume that dark roast coffee often has more caffeine than a lightly roasted coffee bean, this is far from the truth! How long a coffee bean has been roasted has no impact on the caffeine content in the bean. What is usually affected is the weight of the bean the longer it has been roasted the more mass the bean loses. So since a dark roasted bean has less weight.
If you use scoops to measure your coffee, a lightly roasted bean might seem to have more caffeine because there are more of them. But if you measure by weight, a dark roast could appear to have more caffeine because they’re heavier.
Types of Coffee Drinks

Now, let’s get into the practical part. Every coffee lover has their taste and preference for their morning cup of coffee. The coffee you choose to drink affects how much caffeine you’ll get in each cup.
If you’re looking for the drink with the most caffeine per cup your choice should be a cold brew coffee which contains roughly 100-200 mg per 8 oz cup.
Being a coffee lover myself, my favourite morning kick comes from a pour-over coffee. On average, an 8-ounce cup of pour-over coffee has about 80-185 mg of caffeine.
Many folks usually go for the easiest way to make coffee, which is drip coffee. An average 8-ounce cup of drip coffee has around 70-140 mg of caffeine.
Another popular way people try to get their caffeine boost is with an espresso shot. Believe it or not, an espresso shot only has 63 mg of caffeine, which is less than a cup of regular brewed coffee.
So Which Coffee has the most caffeine?
In your quest to unravel the mystery of the coffee with the mightiest caffeine punch, we’ve delved into the world of coffee beans, roasts, and brews. Your desire for that extra morning kick has led us to explore the factors that influence the caffeine content in your cup of joe.
As you read through this article you might have noticed this question has a few variables and it depends on what you’re looking for. If you are a coffee expert and know your bean then your obvious choice would be a robusta bean, as robusta beans have twice the caffeine content than arabica.
For the more simple answer, if you’re looking for the most caffeine per cup of coffee, your obvious choice would be a single shot of espresso since it has the most caffeine in the smallest amount of coffee.
Your coffee journey is not only about taste but also about the science and craft behind each cup. Embrace the nuances, experiment with your preferences, and may your mornings be forever charged with the caffeinated magic you seek.
