Caffeine Content

Most humans rely on that morning cup of coffee to really wake them up, and there is nothing wrong with that. However, do you know, how much caffeine can be found in a cup of coffee? Or even in the bean itself? Besides, caffeine is the most consumed substance in the world. On average, when it comes to the coffee bean there is Arabica and Robusta . A single arabica coffee bean contains 1.9 milligrams of caffeine, that is 1.2 - 1.5g of caffeine per 100g. And a single robusta coffee bean has 2.9 milligrams of caffeine, which is 2.2 - 2.7g of caffeine per 100g. However, some of us wondered why there are different levels of caffeine? What is Caffeine? For short, caffeine is a substance that is like a stimulant for energy. Caffeine can be found in various beverages and it is naturally found in coffee . Caffeine stimulates the nervous system, heart, and muscles. How Much Caffeine Can Be Found in a Cup of Coffee? Caffeine levels can vary depending on the coffee type, bean type, and brewing process. A brewed coffee has 95 - 200 mg of caffeine, while a decaffeinated brewed coffee has 2 - 12 mg of caffeine. The most enjoyed coffee in the world, the espresso has 47 - 75 mg of caffeine, while the decaffeinated espresso has under 15 mg of caffeine. However, a decaffeinated instant has more than the espresso counterpart, because it’s more than 15 mg of caffeine, it is between 27 - 173 mg of caffeine more exactly. And a latte has 63 - 175 mg of caffeine, but don’t get scared of the numbers, that milk can make a difference. Speaking of numbers, these are not even high. If you enjoy a cup of coffee once in a while or have one every day, it is completely fine. How Much Caffeine Can Be Found in a Coffee Bean? I think everyone has heard how much caffeine can be found in a cup of coffee, but in a coffee bean, not much information about that one. Besides, caffeine is found throughout the entire coffee plant, and the highest concentration is within the coffee beans housed inside the coffee cherry fruit. It doesn’t matter that there are 100 species of the coffee plant, because only two varieties make up over 98% of coffee growth worldwide. These two varieties, Arabica and Robusta are the most popular coffee beans on the planet, and even between these two, there are differences in caffeine content found in them. We mentioned that the arabica coffee bean has 1.2 - 1.5 percent of caffeine, and the robusta coffee bean has 2.2 - 2.7 percent caffeine. But why does the coffee plant have caffeine in the first place? The coffee plant contains caffeine because it is toxic to most pests and it acts as a natural pesticide. It’s all about the protection of the plant itself. The arabica plant has a lower level of caffeine because it grows at higher altitudes where few pests live, while the robusta plant is able to survive even at sea level because the caffeine levels are higher. Caffeine Content in Light Roast and Dark Roast Coffee Beans The process of roasting beans does affect the caffeine content found in a coffee bean. The amount of caffeine in a roasted coffee bean has a little less caffeine than the raw, green beans. There is a very common question where people often ask if dark roast coffee has more caffeine than light roast. To make something clear, light roast coffee beans contain the same amount of caffeine as dark roast coffee beans, because the caffeine content remains constant throughout each stage of the roasting process. The caffeine remains stable at temperatures below 235°C. Besides, very few roasters will roast coffee past this temperature because there can be a fire risk. Also, a cup of roast coffee will probably have more caffeine than a cup of light roast. If you wonder how? It is because of the density of the coffee beans. If coffee is roasted darker and darker the beans will lose mass, however, despite the loss of mass, the caffeine content stays the same. If you measure your coffee beans by weight using a scale or by volume using a scoop, the
