For a caffeine fanatic, you may need to identify the highly caffeinated coffee beans so you can enjoy the extra kick of your joe every morning. While all coffee beans contain caffeine, the amount varies depending on several factors. This article takes you through the type of coffee beans with the most caffeine, the type of roast with the most caffeine, the type of coffee beverage with the most caffeine, and the coffee brands with the most caffeine. Read on!


Which Coffee Bean Has Most Caffeine?

There are two main species of coffee beans – Robusta and Arabica beans. These coffee beans are characterized by their caffeine content and their origin. While Arabica coffee beans are considered high quality, Robusta coffee beans are the most caffeinated coffee beans. They mostly originate from Africa, India, and Brazil. Robusta coffee beans contain double the amount of caffeine in Arabica beans. They contain 2.9 milligrams of caffeine per bean, while Arabica beans contain 1.9 milligrams of caffeine per bean.

Robusta coffee beans are considered low-quality beans since they’re cheaper to produce. Furthermore, they are bitter with an earthy taste while Arabica beans on the other hand are sweet and with fruity notes. Although Arabica beans are of high quality, Robusta beans are the winners when it comes to caffeine concentration. Despite Robusta being considered low-quality beans, you can find high-quality Robusta beans with a little digging. Most instant coffee brands use Robusta coffee beans as a result of the high caffeine concentration. So, if you’re looking to enjoy some caffeine kick from your coffee, buy Robusta coffee beans.

Another factor that determines the caffeine concentration in coffee beans is the type of coffee roast.


Which Coffee Roast Has Most Caffeine?

How your coffee beans are roasted can affect the caffeine concentrations in them. There are three main types of coffee roasts. They include light roast, medium roast, and dark roast. The longer the coffee beans are roasted the less the caffeine content. Therefore, lightly roasted coffee beans are more concentrated with caffeine since they are roasted for a short while. However, when it comes to coffee strength, the more the coffee roast, the more the strength. Lightly roasted coffee beans have a weaker flavor, while dark roasted beans have a strong flavor but less caffeine.

So, if you’re looking to enjoy some highly caffeinated coffee, go for light roasts. However, if you’re a dark roast lover, more coffee beans can be used to increase the caffeine content.


Which Type of Coffee Beverage Has the Most Caffeine?

Different types of coffee beverages have different levels of caffeine. The way your coffee is brewed determines how much caffeine it has. For example, French press, instant coffee, brewed coffee, and drip coffee have less caffeine compared to espresso and cold brew. Additionally, the caffeine content in your coffee is also determined by the serving size. For example, a double shot of espresso contains more caffeine compared to a regular drip coffee. Also, a 20oz Starbucks venti contains more caffeine compared to espresso coffee. Here is a list of different coffee beverages and their caffeine content per serving.

  • 8 ounces of drip coffee contain 65 to 120 milligrams of caffeine
  • 8 ounces of brewed coffee contain 95 milligrams of caffeine
  • 16 ounces of cold brew coffee contain 200 milligrams of caffeine
  • 16 ounces of nitro cold brew coffee contain 325 milligrams of caffeine
  • 2 ounces of espresso (one shot) contain 60 to 102.67 milligrams of caffeine

Generally, cold brews and lighter roasts contain more caffeine. Therefore, if you’re a caffeine-fanatic try some cold brew coffee that’s made with a blonde roast. Most importantly, keep in mind that overconsumption of caffeine can lead to headaches, insomnia, increased heartbeat, dehydration, and anxiety. The recommended amount of caffeine to consume daily is 400 milligrams.

An 8-ounce cup of coffee contains approximately 100 milligrams of caffeine per serving depending on the coffee beans used, the type of roast, as well as the brewing method used. Several tricks can be used to add caffeine content to your cup of joe. They include slightly increasing the coffee to water ratio, finely grinding your coffee beans than normal, increasing your water temperature (195 to 205 degrees Fahrenheit), and increasing your brew time.
