What Roast of coffee has the most caffeine?

As a coffee enthusiast, it is not impossible that you have sometimes wondered which of the kind of coffee roast contains the most coffee. Your curiosity may stem from the fact that you intend to limit your caffeine intake for health or personal reasons or, well, you are just curious for curiosity sake. Whichever way, from this article, we will consider some of the myths around the subject of caffeine content in roast methods and see which really holds ground. 

Roasting Method: Light or Dark Method.

We have found out that most coffee enthusiasts and drinkers consider the type of roasting method the most significant factor that influences the level of caffeine in a coffee brew. Well, this may be true, it is essential that you understand that it may not be as significant as you may think. The dark toast generally seems more intense while the light toast typically has the floral or the fruity underpinnings. Many people use the difference in the texture to assume that the dark coffee has more caffeine. Well, the truth is that this difference applies mostly to the flavor and not necessarily the caffeine content. Also, we have people mentioned that the burning process of the dark toast may make it lose some caffeine content and thus, the light toast may have more caffeine. Well, this is a conjecture and not necessarily a fact in any way. What actually occurs during the roasting process is that the beans expand and may lose more water, grow larger and lose density. Thus, at measurement, the lighter roast may have more bean volume. And, it may true that more beans translate to more caffeine.

The brewing method

Now that we have considered the roasting process and realized that there is no much difference in the caffeine level between the two toast, we will consider the brewing method and see if a significant difference might in the caffeine level of an expresso or a drip coffee. 

Of course, the extraction process during each specific brew may influence the caffeine level; it may not be as significant as you think. Typically, the length of the brewing method will affect the caffeine level. Thus, the longer the brew method, the more caffeine you should expect in a cup of coffee. Take note; the critical factor lies in the serving of coffee per cup. 

Thus, in the case of an expresso, a single ounce shot of the cup contain around 40 mg of caffeine. On the other hand, a 12 oz mug of a drip brew contains about 12 mg. Thus, if the ounce by ounce comparison of these brew in anything to go by, we will realize that the expresso contains the more caffeine ( 40 mg to 10 mg per ounce). However, we hardly ever take 12 ounces of espresso at a go. Thus, we will get more caffeine in drip coffee than in a cup of espresso. 

means that in a single serving, you’ll get more caffeine in a cup of a drip coffee than in a shot of espresso.

For a cold brew coffee, you will almost always have more caffeine in a cup compared to a drip coffee. This is because they are typically brewed with a higher water to coffee ratio, which generally much in part on your preferences.

Here is the bottom line here too: if you are looking to change your coffee diet based on the caffeine level, the brewing method shouldn’t probably be something to be expressly considered. Thus, we will advise that you should make your decisions based on your taste preferences. 

What does the coffee beans have to say?

Here we come to what actually make a more significant point; the coffee beans. Generally, the Arabica beans are considered to have a better quality compared to the Robusta beans. But that is beside the point. The Robusta beans have nearly twice as much as caffeine content as the Arabica beans. The Robusta beans are more accessible as it is cheaper and more common in store. It is also known for its sweet and fruity flavors. However, as mentioned earlier, the Arabica beans have better quality, smoother taste, and better flavor. This is probably because it has lower caffeine content. Another interesting point to note is that it is common to have a blend of these two beans just like the Death Wish coffee 


Here is the conclusion of the whole matter. The caffeine level is not really a matter of dark or light toast. The level of caffeine you have in a cup of coffee is determined by the amount of coffee you use when brewing. Thus, if you want more caffeine, just put more coffee. It is that simple.
