Comparing Light and Dark Roasts – Does One Have More Caffeine Than the Other? 

When comparing dark and light roasts, is there a difference in caffeine content or is this a myth? 

When measuring your coffee using a scoop, the lighter roast will have a higher caffeine content as the beans are a lot denser than darker beans. 

Too much caffeine gives one the shakes and jitters. Adjusting the amount of caffeine consumed daily to make this a pleasant experience is what it is all about. Bear in mind that tea also contains caffeine. 


What We Know About Caffeine and Your Cup of Joe 

  • What we know for certain is that the colour of the coffee you drink, whether light or dark, is not a measure on how much caffeine it contains 
  • Just because your coffee is strong and has a bold taste is not an indicator of caffeine content 
  • The darker roasted coffee beans appear to be a lot bigger than lighter coffee beans. This is because they expand because they are exposed to heat for longer during the roasting process 


Interesting Fact – the Way You Measure Your Coffee Will Determine the Amount of Caffeine 

  • The way you measure your coffee will impact on the amount of caffeine you consume. Whether you use a coffee scoop or a scale, this will impact on the result and caffeine content 
  • Lighter roast beans are smaller and denser because they have had less exposure time to heat during the roasting process. More beans = more coffee = more caffeine 
  • Investing in a little scale is a smart idea to measure your coffee accurately. This is a great way to ensure you are getting the perfect amount of coffee regardless of the size of your coffee bean whether light or dark 
  • Think of it this way – larger, darker roast beans will be less bean and therefore less coffee and less caffeine 


 Most and Least Caffeine Content – How Much Does Your Drink Have 

  • Cold brew coffee contains the most caffeine per cup. This is as a result of high concentrations of the beans to water ratio and lengthy brewing 
  • Your cup of drip coffee contains up to 200 grams per serving in a standard cup 
  • And here’s a surprise for espresso lovers – there is only about 75 mg of caffeine per espresso shot (bear in mind espresso is served in much smaller cups) 
  • Espresso has more caffeine than ordinary coffee; the primary reason why it is served in tiny cups  
  • Black tea contains up to 70 mg of caffeine in a regular cup 
  • Green tea has about 45 mg of caffeine in a regular cup 

Drip coffee, espresso, green tea or black tea – everyone has a favourite drink. Too much of a good thing is never good for you regardless of how much or little caffeine the beans have. Limit your daily intake of coffee to maintain a good balance, regardless of the colour of your roast or caffeine content.
