How Much Caffeine Is in Coffee?

Nothing gets the day started like a good cup of coffee. This welcome jolt of caffeine gets us up and moving and keeps us going throughout the day. But how much caffeine is in your morning cup of joe?

Caffeine is a naturally occurring stimulant found in coffee beans. Typically, an eight-ounce cup of coffee contains 90-100 milligrams of caffeine. The Mayo Clinic recommends that healthy adults limit their caffeine intake to 400 milligrams per day. This includes coffee and any other sources of caffeine you may consume during the day, including tea, soda, chocolate and energy drinks.

What Effects the Amount of Caffeine in My Coffee?

When it comes to caffeine in coffee, however, not all beans are the same. The caffeine content of your coffee depends on a few factors:

  1. Type of coffee bean used
  2. Brewing method
  3. Amount consumed

Bean Type

The two types of beans that are used to make coffee are Arabica and Robusta. Robusta beans are generally higher in caffeine than Arabica. However, the taste of Arabica beans is considered superior, bringing sweeter, softer notes and hints of fruit and berries to the coffee.

 

Brewing Method

You may have heard that darker roasts have more caffeine, but this isn’t true. Dark and light roasts have nearly identical caffeine content. What really differentiates the amount of caffeine in your drink is the way in which the drink is brewed and how much coffee you use.

Typically, the longer water has contact with the grinds, the stronger the coffee. That makes cold brew an especially potent concoction, while espresso actually has less caffeine than you might think since it is not in contact with water as long. However, keep in mind that cold brew typically has water added prior to serving, as well as milk or cream, while espresso is consumed in its original, concentrated state.

At Mars Drinks, we use our Freshpacks to get the most out of every cup of coffee we brew. In fact, we attain 60% greater extraction than our competitors, since our pack design ensures an even distribution of water over the grinds.

Amount Consumed

One of the biggest factors effect caffeine content is simply how much you drink. It’s definitely the most straight-forward factor effecting how much caffeine is in your coffee, but it’s often overlooked. For instance, it’s not unusual to drink a 24 ounce hot or iced coffee or to order a large latte with three shots of espresso. This really ups the caffeine content, though you may not realize how much caffeine you’re consuming since it’s “only” one drink.

How Much Caffeine Is in Decaf Coffee?

Decaffeinated coffee is almost identical to caffeinated coffee- it is still made from either Arabica or Robusta beans- but it has undergone a process to remove the naturally occurring caffeine within those beans.

The resulting products tastes just like caffeinated coffee, but at least 97 percent of the caffeine has been removed. A very small amount of caffeine may remain, but it is typically in the two to ten milligram range. Our Alterra House Blend Decaf and Alterra French Roast Decaf, for instance, have about four milligrams of caffeine, a huge decrease from the 90-100 milligrams found in their caffeinated brethren.
