Cup of coffee caffeine content3/23/2023 Instead, I called upon a certified test lab to calculate the exact numbers for me, you and the whole world of coffee lovers.įrom what I can tell, we at Coffeeness are so far the only ones out there who have taken this beyond a mere scientific curiosity, actually putting in the effort to run these kinds of tests and then making them available for anyone to see. I didn’t want to just use ballpark figures or back-of-the-envelope calculations to figure out how much caffeine is in different kinds of coffees. I’ll even admit that I myself have worked with these inexact and unproven numbers - at least when there was a lack of better evidence. Many people take those claims at face value because they sound authoritative, and because we want our blogs and news sites to have “evidence” and “proof.” Heck, you could even pick two beans growing next to each other on the same branch, and they each might contain different amounts of caffeine - and that variation will only grow more pronounced if you roast them differently.ĭespite all that, you’ll still find all kinds of claims about the amount of caffeine in a cup of drip coffee or a shot of espresso, although nobody seems to know where these numbers actually come from. There are obviously enormous variations between Arabica and Robusta beans, but you can even notice significant differences between beans of the same variety, such as an Arabica bean from India and another Arabica bean from Guatemala.

NCA Members can dive deeper into the issues currently facing decaffeinated coffee. Every body is different, so everyone should check health recommendations from recognized authorities, listen to how your body responds to caffeine, and consult your personal physician if you have any questions. Guidelines may vary for people with certain medical conditions.Īs you think about caffeine intake, be mindful that caffeine is found not just in coffee but also in other foods and beverages, so consider all potential sources. Regulators and health authorities in the United States and around the world have concluded moderate caffeine intake can be part of healthy diets for most adults - generally up to 400mg per day, or about 4-5 cups of coffee. FDA measures these traces in “parts per million.” After decaffeination, coffee can contain no more than 10 parts per million of, for example, methylene chloride - that’s one one-thousandth of a percent. Food and Drug Administration has set a rigorous standard to ensure that any minute traces of solvents used to decaffeinate coffee are safe. All four methods are safe, and once the caffeine is removed (well, at least 97% of it), the beans are washed, steamed, and roasted at temperatures that evaporate the liquids used in decaffeination. If you are wondering whether the decaffeination process itself is safe, the answer is yes. Like all coffee, decaffeinated coffee is safe for consumption and can be part of a healthy diet. A typical cup of decaf coffee has about 2 mg of caffeine, compared to a typical cup of regular coffee, which has about 95 mg of caffeine. The hard beans are warmed and soaked in liquid to dissolve and remove the caffeine in one of four ways: using water alone, using a mixture of water and solvents (most commonly methylene chloride or ethyl acetate) applied either directly or indirectly, or using water and “supercritical carbon dioxide.”Īll four methods are safe, and once the caffeine is removed (well, at least 97% of it), the beans are washed, steamed, and roasted at temperatures that evaporate all the liquids used in decaffeination.ĭecaffeination removes about 97% or more of the caffeine in coffee beans. Like regular coffee, decaf coffee begins as green, unroasted beans. Luckily, a serendipitous accident in 1905 swamped a shipment of coffee beans with seawater, washing the caffeine out and prompting the development of modern decaffeination methods. More than 90% of American coffee drinkers choose caffeinated brews, but decaf is a great option for those who want the taste and social connections of drinking coffee without the energy boost of caffeine. Independent scientific evidence shows coffee, with or without caffeine, is associated with many unique health benefits, including increased longevity and decreased risk of multiple cancers and chronic diseases.
