It is seen as a more luxurious type of coffee as it is smoother and usually has more flavour than other types of coffee. This of course is still a very low intake of caffeine and most decaffeinated coffee contains this same range although some types can be higher or lower, depending on the brand.Įspresso is made by forcing a small amount of hot water, or steam, through finely-ground coffee beans. One cup of brewed coffee contains about 70–140 mg of caffeine or about 95 mg on average so this is really the baseline for coffee and what most peoples’ average caffeine intake would be.Īs seen in the name, decaffeinated coffee is much lower in caffeine yet is not completely caffeine-free! It may contain varying amounts of caffeine, ranging from 0–7 mg per cup, with the average cup containing 3 mg. Probably the most common variant of coffee, brewed coffee, known as regular coffee is made by pouring hot steamy water over average ground coffee beans within a filter. Each variant has different caffeine levels ranging from almost nothing to the highs of 500 mg! Here are a few examples to show just how broad the caffeine levels in coffee truly are… Your average cup of coffee contains around 95 mg of caffeine, yet this does not apply to all types and variants of coffee. Additionally, Robusta coffee beans have around twice the caffeine content of Arabica coffee beans, so there are plenty of factors that can change caffeine content in your favorite coffee.Coffee is the first thing that comes into your mind when someone says caffeine. Water temperature, grind size, and pressure change extraction. Other variables change the caffeine content in each beverage. Getting back to my point, to serve a cup of drip coffee of 250 ml, we use near 18 grams of ground coffee, a similar amount to a double espresso dose. The ratio of coffee and water is what we call the brew ratio, and I’m sure you can find more information about it in an article in The Coffee Lab. For this reason, a regular cup of coffee can rival the caffeine content with a double shot of espresso. While an espresso takes 1 to 2 water per part of coffee, drip coffee can use 14 to 18 parts of water per part of coffee. As you may know, espresso is more concentrated than drip coffee. The tricky thing here is the concentration of each beverage. That’s more than four times the size of a double espresso! A double shot of espresso measures approximately 60 ml, while a regular cup of coffee can measure 250 ml and even more. I promise all this information is relevant to answer your question.įirst, let’s consider the size of each serving. In comparison, an 8 oz cup of coffee (near 240 ml) has 95 to 128 mg of caffeine.Įxplaining the reasons behind it is interesting. According to the Department of Nutrition of the United States, a double shot of espresso has around 126 mg of caffeine. According to most research, many variables complicate to offer a single number. You’ll be surprised to learn that a double espresso has almost the same amount of caffeine as a cup of drip coffee. So, hopefully, my answer will help you, and many others too. Many people are concerned about their health, and the impact of caffeine intake in their lives. Hi Tanya, thanks for this interesting question.
