Caffeine The Myth - Deep roasted and Espresso contains more caffeine?



It's not hard to understand why people would typically assume darker coffee contains more caffeine and works better in keeping them awake, but, is it true? It seems that we never really dig information before getting into conclusion.

"It is a myth why darker coffee gives an impression that they contains more caffeine than the light ones...."

Some people think the darker the coffee, the more mineral or contents has been extracted from the bean since they taste stronger. Therefore the darker roast beans and certain brewing method that associated with strong flavor coffee like espresso would deliver more caffeine.

For some barista, they think darker roast should contains less caffeine since the temperature goes so high that it seems to them the caffeine will be burnt off from the bean.

TIME TO SOLVE THE MYTH ! WHICH CONTAINS MORE ?

Let's throw away all the bias and look at the truth, which contains more caffeine.

DARK ROAST vs LIGHT ROAST ...

SAME, caffeine is a very stable substance, the roasting level cannot do much on the caffeine.

which means temperature doesn't really matter...

ESPRESSO vs HAND DRIP COFFEE

HAND DRIP COFFEE actually contains more caffeine PER SERVE. what does matter is how much coffee is used to make the serve, Espresso is served in shots which is 1 oz, let's say it contains 40 milligrams of caffeine, with the same log of bean and brew with hand drip method, for a 12 oz service it deliver 120 milligrams of caffeine ! which means water pressure is a fact but the volume is more vital....

COLD BREWING vs HAND DRIP COFFEE

COLD BREWING wins. because it needs more coffee to brew a serve and the brewing time is much much longer when compared with the hand drip ones. So when they are compared in per serve, cold brewing wins hand drip and espresso.

which means brewing time and amount of coffee does matter...

LAST BUT NOT LEASE

the types of bean does matter a lot e.g. the caffeine content in Robusta is a double then in Arabica.
