Are you wondering which coffee roast has more caffeine, a blond or dark roast? If so, then this article is meant to be read by you.

Did you know that the temperature to which the coffee bean has been heated makes it either a blond, light, medium, or dark roast? Although this does impact the caffeine content in the coffee bean, the coffee beans also get another flavor profile depending on the roast.

The truth is, if you brew coffee using the same amount of coffee by weight, the caffeine content will be the same for every brew. So it doesn’t matter if you’re using blond or dark roasted coffee beans.

This can, however, change depending on the person making the coffee. Some people like using cups to measure how much coffee they need for their coffee brewing. This will always result in a difference in caffeine. Read along to find out!

What is a Blonde Roast

When looking at a blond roasted coffee, you will notice many similarities to the lighter roast. This is true. A blonde roast is the same thing as a light roast, just roasted at the lowest possible temperature.

Most of the time, the coffee beans will reach an internal temperature of 180°C (356°F), which will leave a big flavor profile to discover. With each country and their coffee farms producing coffee beans with a very different flavor profile, there is a lot to try out.

Light roasts and which flavors can you find in the coffee

All the roasting temperatures and data of them are from coffeecrossroads.

The light roast is made popular by Starbuck in 2018 while introducing the blond roast, which is basically the same thing as a light roast.

The coffee beans are generally roasted to reach an internal temperature of 180°C – 205°C (356°F – 401°F). The first crack happens around 205°C. (401°F)

To make it easier to understand, you can remember this: the coffee beans for the light roast are not roasted beyond the first crack.

Depending on the coffee bean origin, the flavors you might find are as follows: soft, sweet, some fruits, and cinnamon. These are just a few examples of flavors I have tasted in a lightly roasted coffee.

Medium roasts

When looking at this roast of coffee, you can really see a difference in color happening. The color is slowly starting to change towards a darker color associated with a big coffee flavor change.

Medium roasts reach internal temperatures between 210°C (410°F) and 220°C (428°F) — between the end of the first crack and just before the beginning of the second crack.

Medium-dark roasts

As you might have noticed in the picture of the medium-dark coffee roast, this is the roasting stage where you can see some oil beginning to show on the coffee beans.

The beans are roasted to the beginning or middle of the second crack — about 225°C (437°F) or 230°C (446°F). The roasting process’s flavors and aroma become noticeable, and the taste of the coffee may be somewhat spicy.

So, what about dark roasted coffee beans?

These are the most commonly used coffee beans to make an espresso or even an Americano. This is because of the bold and strong flavors developed in the coffee bean while roasting.

The oil on the coffee beans surface is significantly increased, and this will leave the oily consistency behind in your coffee brewer and grinder.

To reach a dark roast level, coffee beans are roasted to an internal temperature of 240°C (464°F) — about the end of the second crack — or beyond.

They are seldom roasted to a temperature exceeding 250°C (482°F), at which point the body of the beans is thin, and flavors of tar and charcoal characterize the taste.

But, which of the four has the most caffeine content?

Looking at the four roast stages, there is one key difference when you are looking for a coffee with high caffeine content.

Robusta coffee naturally has more caffeine than Arabica. Robusta has almost twice as much caffeine compared to all the other coffee beans out there.

Most single-origin coffees come from the Arabica coffee plant unless stated otherwise on your coffee beans’ packaging. If you are a fan of coffee beans with a greater caffeine content, always choose Robusta coffee beans.

So, which roasting has the most caffeine? It really depends on how much coffee you use for your brewing method.

Whenever you use the same amount of coffee based on weight, you will have the same caffeine content; whether you are brewing with a light or dark roast.

Generally speaking, dark roasted coffee beans have more caffeine because a lot of water has been evaporated while roasting the coffee.

If you take 18 grams of coffee beans to make a filter coffee, you will have the same caffeine content when using a light or dark roast.

How does the brewing method matter?

When you start brewing coffee at home with a bean of your choice, you can make sure you get the most caffeine in your cup by changing your brewing techniques.

Name of coffee:Amount of fluid ounces and ml:Caffeine content:
Ristretto0.8 oz or 25 ml35 mg
Espresso1.2 oz or 40 ml45-75 mg
Pour over8 oz or 235 ml80 mg
French press8 oz or 235 ml107 mg

By looking at this table of caffeine content in the coffees, we can see that the ristretto’s caffeine content is the highest compared to all the others by coffee ounces.

Personally, I would much rather choose a well-brewed cup of French press coffee over a ristretto any day. This way, I get to enjoy the coffee taste in the morning for a longer period of time.

Does acidity has an impact on your coffee experience?

Most people compare strong coffee with acidity and a strong flavor profile. This is because the taste of acidity in your coffee can be overpowering.

If you have experienced this as well, I can recommend drinking more pour-over coffee like Chemex. This will filter out most of the strong flavors and will result in an easy drinkable cup of coffee.

Most espresso bases drinks have more acidity in them, from roasting the coffee beans. When making an espresso at home you want to make sure you have a nice dark roast, which will give you a flavorful coffee to start your morning.

Would you like to know which coffee beans your favorite coffee bar uses? Just ask them, they will be happy to tell you. You might notice that most of them will indeed use dark roasts or a roast that comes close to the bold flavor that dark roasts have.

Which coffee roast is right for you?

When choosing which coffee beans to buy, you want to figure out which flavors you want to find in your coffee. This is the most important thing to remember, buy what you like.

I would recommend trying a few coffees from all four of the roasts. This will give you a good idea of which flavor profile you like in your coffee, and now you can search for this specific flavor when buying your coffee beans.

When looking for coffee beans online, you want to make sure you have all the necessary information you need to make a decision on which coffee you are going to buy.

Now you can choose which coffee beans you want to order online or at your local coffee roaster. Once you get the hang of it, you will find more excuses to drink coffee, and you will enjoy it even more!


There you have it. The truth about the caffeine content in your early morning coffee. While all the coffee roasts have the same caffeine content by weight, the coffee flavors can be very different from each other.

Remember: the darker the coffee roast, the more sweet, mild, and flowery flavors get lost. For me, this is very useful, and I would much rather be enjoying a bigger cup of coffee in the morning and save the espresso for the tough moments the day has to offer.

  1. hi jeffrey
    you say” darker roasts have more caffeine” which is contrary to what most other articles on the internet.

    to quote from your article, “Generally speaking, dark roasted coffee beans have more caffeine because a lot of water has been evaporated while roasting the coffee.”

    • Hi Cici,

      Thanks for leaving a comment on this; let me explain this further.

      Because dark roasted coffee beans weigh less, it contains more caffeine than a different coffee roast, if you use the same amount.
      They weigh less because they are roasted longer. The longer you roast coffee beans, the more water evaporates.

      So, if you make a cup of coffee with the French press, using dark roasted coffee beans, and one cup with a medium roast, the cup of coffee using dark roasted coffee beans will have more caffeine. If you weigh out 20 grams of dark and medium roasted coffee, you’ll see that you have more coffee beans when using a dark roast: more coffee beans = more caffeine in your coffee.

      I hope this answers your question. If you have any other questions, please let me know, as I’m happy to help.


  2. Hi there, you may want to do a quick fact check. Robusta coffee tends to be far more bitter due to caffeine content. Coming in at 2.4% caffeine it is twice the strength of the far more popular Aribica beans.
