Dark Roasts

Many coffee lovers believe that dark roast coffee beans have higher caffeine than light-roasted beans, which is not true. Most people also believe that the darker the roast is, the lower the bean caffeine.

People justify this belief by saying that the bean’s caffeine is lost or burned off because of high roasting. However, during the roast process, the caffeine change is very less.

If you want to notice a significant change in caffeine, you will have to roast the coffee beans above 600° F temperature, which is difficult. During the roasting process, the temperature rarely exceeds 470° F, due to which the caffeine amount almost remains the same. However, you will notice a difference in flavors only.

Light Roasts

Some coffee lovers might be surprised to know that lightly roasted coffee beans contain more caffeine than dark roast coffee beans. You might have heard a few coffee drinkers explaining that the darker blends are roasted for an extended duration, due to which they lose more caffeine.

This is somewhat right because, during the roasting process, some of the caffeine is removed, but that caffeine loss is very less. However, the truth is that during the roasting process, the beans expand.

Roasting beans for a longer period will make them lose more water, resulting in larger growing and less dense. Therefore, if you measure the coffee by volume, the lighter the roast, the more beans there will be. More beans indicate that there is more caffeine content. However, this difference is quite small.

On the other hand, if you use weight to measure the coffee, you will find out that both the dark and light roast coffee contain similar caffeine. So, the impact of roasting on the amount of caffeine is quite minimal. Therefore, you should decide based on your taste preferences rather than the caffeine quantity whenever you select a coffee.

Brewing Method and Caffeine

You might think that if the roasting does not affect caffeine content, does the brewing method impact the caffeine quantity? Will the espresso machine produce coffee with more caffeine than drip coffee? Well, yes, the brewing method does affect the amount of caffeine.

As a general rule, if you perform the brewing method for a longer time, you will get more caffeine per serving. As per Kicking Horse Coffee, you will get 40 milligrams of caffeine with a single one-ounce of espresso.

On the other hand, you will access 120 milligrams of caffeine with a 12oz mug of drip. So, if you conduct an ounce-to-ounce comparison, you will find that the espresso is stronger than drip coffee. But we are not going to consume 12 ounces of espresso in each serving. Therefore, in a cup of drip, you will attain more caffeine than in espresso.

Type of Coffee Beans and Caffeine Content

Another question arises whether beans decide the caffeine quantity or not. Well, yes, beans do make a real difference in the quantity of caffeine. Arabica or Robusta are the two popular bean choices that coffee lovers usually prefer.

Robusta Beans

The Robusta coffee beans come from the plant Coffea canephora, which has greater bitterness and low acidity. You can use Robusta coffee beans in both espressos as well as in instant coffee. Some brands also utilize Robusta in ground coffee blends as a filler.

Comparing the amount of caffeine in Robusta and arabica beans, you will find that the caffeine content in a Robusta bean is higher. The caffeine in Robusta is twice the quantity as compared to arabica.

Even some types of Robusta bean contain nearly four times more caffeine in them. The greater quantity of caffeine available in the Robusta bean indicates that it is more resistant to pests. However, the taste of Robusta beans is not that tasty. It has a more bitter and bland taste.

Arabica Beans

Arabica beans are another popular type of beans that many coffee lovers choose to prepare delicious coffee. The arabica plant is the prime source of an arabica bean.

Because of its taste, this bean is regularly used all over the world. Some of the famous kinds of Arabica beans are Kona, Villalobos, Caturra, etc. Though the caffeine content in Arabica beans is lower than the Robusta beans, many coffeehouses still use the Arabica bean because of their better taste.

As a result of lower caffeine content, you will experience complex flavors with this type of beans. Therefore, if you want a coffee with high stimulating property, you must go for Robusta coffee. But if you want something tastier, then the Arabica beans will be an ideal pick for you.
