Strength of coffee

Today we investigated what strength of coffee depends on.

Everybody knows that stronger coffee has more caffeine. However, this "more" part can have different meaning.

For instance, we can compare normal "drip" coffee and the famous "espresso" type.

Espresso Coffee

In one cup of "drip" coffee we may find 95 to 200 mg of caffeine. While in the cup of "espresso" there is usually 47-75 mg.

So you can see, "drip" coffee actually has MORE caffeine in a cup than "ESPRESSO".

Don't be fooled though. The "espresso" coffee actually has MORE caffeine per ounce, normally 61 mg. While the "drip" coffee has only 18 mg per ounce of fluid.

This is why you can have this "UP" feeling from the "espresso"!

Coffee with milk

And then, if you add milk or other liquid creamers and dilute your coffee drink, it will reduce the caffeine concentration.

There is more to consider about caffeine than just the type of coffee drink.

It's very important what kind of beans you use and how they're prepared.

Caffeine (and other precious ingredients in coffee) tend to degrade when interacting with the oxygen in the air. That's why stale coffee looses it's flavor pretty fast.

Coffee beans with different roasts

In darker roast coffees caffeine concentration is slightly decreased in favor of stronger flavor.The way coffee beans are roasted (cooked) directly affects the caffeine concentration in your drink too. Lighter roast will keep more caffeine in the beans.

The dark roast beans have darker color, so you can easily tell what is what. This happens because for we roast coffee longer and more caffeine burns away.

It important to note that caffeine percentage in the beans is different for coffees from different countries:

Bag of Coffee from Columbia
  • Yemen - 1.01%
  • Ethiopia - 1.13%
  • Kona (Hawaii) - 1.32%
  • Tanzania - 1.42%
  • Robusta - 2.40%

Finally, how you prepare your coffee beans for the drink is essential to the caffeine concentration in the cup. Finer grinds will result in larger area of contact with water and higher concentration in the cup.

Hot Coffee

Make sure to use the hot water between 195-205 degrees to allow caffeine transfer faster from the beans into your cup. That means, don't pour boiling water right away. Allow the water to loose some heat for 5 minutes after it's boiled.

More brewing time will let more caffeine to escape from beans into water.

Now you know how to choose, prepare and enjoy your fully charged drink!
