How Much Caffeine in a Cup of Coffee?
Many of us just can’t get through the day without our morning cup of java, whether it comes from the home drip machine, the corner coffee shop, or a coffee pod machine at the office. Coffee is a sweet treat, and a happy little pick-me-up. We are all aware that caffeine is a big part of coffee, but do we really know how much we are putting in our bodies with each cup? Caffeine comes in many foods and drinks, so who is consuming the most caffeine – a coffee drinker, chocoholic, energy drink junkie or soda drinker? Here we will analyze how much caffeine is in a cup of coffee, and what that means.
The amount of caffeine in a single cup of coffee can vary a lot. It depends on the type of coffee and the way it’s been brewed. For example, in a 7 ounce cup, ordinary drip-brewed coffee (which is the most common) has about 150 milligrams per cup. Other types of brewing can produce a cup with anywhere from 80 to 175 milligrams per cup.
On the other hand, instant coffee has anywhere from 65 to 100 milligrams per cup. Even decaf coffee has some caffeine as well. With only about 6 milligrams for brewed decaf and less than 3 for instant, it is quite negligible. Yet, it is there.
So, how does that compare to other foods? After all, it’s hard to get a good idea of what a cup of coffee contains if you don’t have a scale to judge it on. Twelve ounces of iced tea contains about 70 milligrams of caffeine, with hot brewed tea usually having between 40 and 60 milligrams. Also, instant tea has about 30 milligrams. A caffeinated soft drink might be anywhere between 20 and 40 milligrams, and 8 ounces of cocoa could be between 3 and 30. An ounce of milk chocolate offers 1 to 15 milligrams of caffeine, and an ounce of more potent dark chocolate 5 to 35. Caffeine pills range between 100 and 200 milligrams of caffeine each, and a caffeinated cold medication comes in at about 30 milligrams.
Of course, there’s a wide range for every cup, since even the same person using the same ingredients and equipment every day is going to produce a cup of coffee or tea with vastly different caffeine content. Coffee is one of the more potent sources of caffeine, but it’s not the most potent or the only one out there. How much caffeine, really, is there in that morning cup of joe? It has a lot to do with the method – it will depend upon how it’s made and the cup you’re drinking.
