Caffeine...Friend or Foe?

While many of you are probably accustomed to the word caffeine being associated with productivity, happiness, and sanity… you now find yourselves moving into a love/fear relationship with your old friend.  The best remedy? Knowledge…

The amount of caffeine in a cup of coffee depends on many factors.  In the table below we’ve summarized the general rules about what makes coffee more or less caffeinated.  


Coffee with Less CaffeineCoffee with More Caffeine


1 The Bean - Two main species of coffee plant are used to produce coffee.  Coffee Arabica constitutes 75% of coffee beans grown worldwide. On average, it has 1.1% caffeine. Coffee Robusta is the second most popular bean and is often used as a filler for Arabica blends.  It has, on average, 2.2% caffeine.

2 The Roast – Because beans expand during roasting, beans that are roasted longer (dark roast) are generally larger than beans that are roasted for a shorter period (light roast).  As a result, dark roasted beans have more caffeine by weight (using a scale) but light roasted have more caffeine by volume (using a scoop).  Since measurement practices may differ, if you’re at a coffee shop it’s always a good idea to ask about caffeine level.

3 The Size of the Beverage - Ounce for ounce, espresso (~40 mg/oz) has more caffeine than drip coffee (~10 mg/oz).  However, when you look at standard serving sizes, a 2 oz double espresso shot of espresso has 80 milligrams of caffeine compared to 120 milligrams in a 12 oz. cup of drip coffee.
