Caffeine is a stimulant that enhances your brain functioning power and in the short-term boosts up your metabolism and exercise performance.

Coffee, tea, chocolate, and soft drinks all contain caffeine. Our much needed early morning cup of coffee sadly has the most. Caffeine is regarded as the most commonly consumed Psychoactive substance on our planet.


Caffeine blocks the functioning of our inhibitory neurotransmitter. Easier known as our Brain Hormone. Also medically known as Adenosine.


By obstructing the adenosine, the caffeine in your coffee is able to increase the activity in our brains. At the same time caffeine releases other neurotransmitters called Dopamine and Norepinephrine. Thus reducing the effects of tiredness and having the opposite effect of increasing our alertness.


Is that all you need to know about caffeine in your coffee?

Alas no, the above chart gives you the basic knowledge of what to expect in one of your favourite coffees. Now let’s look at the source of your coffee, do you drink Arabica or Robusta coffee? As the type of bean in your coffee matters.

It’s safe to regard  Arabica Beans to be of a higher quality than Robusta Beans.

Arabica is the harder of the two species to farm but does produce wonderful sweet and fruity flavours. Only drawback, these same beans have on average twice as much caffeine than it’s counterpart the Robusta.

Now, if your taste buds prefer a strong bitter-earthly taste, then seek out the Robusta bean. These have less caffeine and costs less to produce. Nearly all the supermarket brands around the world will have Robusta beans as the main ingredient.

Your next  2 questions. Does the type of roast matter?

Does Light Roast have more caffeine than Dark Roast?

Yes and No. Both roasts bean for bean has almost the same number of mg of caffeine.

When beans go through the roasting process, they will lose some of their body mass. Now it stands to reason the dark roasted beans will weigh less than their light roasted counterparts. Pound for pound in weight the dark roast will generally pack more beans.

Subsequently, do you measure out by volume in which case the light roast will have more caffeine or do you measure by weight? If so guess what, the dark roast wins.

Confused? I know I was.

How about if I explain it this way?
  • For every cup of light roast, you are going to have more caffeine than a cup of the alternative dark roast. Why? Because the light roast has denser and heavier beans.
  • Now if you measure out say 25 grams of each light and dark roast. The latter will have more caffeine due to the extra volume.
  • Yes, it’s true they both weigh the same – 25 grams but remember the dark roast beans have less density, and therefore you actually have one or two more.

Now, refer back to the original chart showing you the various coffees and the amounts of caffeine in each. It is time to investigate other types of beverages available.

Americano drip coffee vs. Espresso?
Americano drip coffee vs. Espresso?

The size of your beverage has its role to play in the confusion on whether espresso is the better choice over a drip coffee. Guess what? Espresso does not appear to be the better choice.

An 8 oz drip coffee is the ideal choice if you wish to reduce your quantities of caffeine. Try not to forget that espresso has per ounce more caffeine (40 – 45 mg) and drip although greater in volume has only 9 -18 mg.

Also, bear in mind, the exact caffeine content in your daily cup of tea or coffee will vary depending on where it originated from, what preparation & processing methods were used, and finally, the actual brewing time.

What are the positives and negatives of caffeine in my coffee?

Positives.

Apart from the boost in metabolism and enhancing your exercise performance in the short term. Caffeine in your coffee can have other benefits that will please you.

  • Coffee drinkers have been shown in various observational studies around the world may have a lower risk of between 32 to 65% in developing Parkinson’s Disease.
  • Sadly, there are over 300 million souls around the globe are registered type 2 diabetics. Again observational studies have shown that regular coffee drinkers can reduce their risk of developing diabetes by between 23 to 67%.
  • Another positive for coffee drinkers, further observational studies have shown that coffee drinkers have up to 40% lower risk of attracting Liver cancer.
  • We coffee drinkers are happy people and less prone to depression and suicide. By drinking as much as four cups of coffee per day can lead to a suicide reduction rate of 53%.
  • There are observational studies completed at Harvard University back in 2011 that demonstrate us coffee drinkers live longer than our non-coffee drinkers neighbours. The main drawback, we’ve got to drink 4 to 5 cups of our favourite coffee per day.
Negatives
  • There are no negatives with your caffeine in your coffee. Sorry only kidding.
  • If we drink too much coffee, caffeine intake can lead us to be jittery or anxious. We can experience heart palpitations and panic attacks.
  • If you are still drinking coffee after 2 pm each day, you might find your sleeping quality is disrupted. You might start to suffer from insomnia. Best to revert to fresh water for the afternoon and evening.
  • I am sorry to say that caffeine is an addictive substance and without it can lead some of us down the path of headaches, migraines, lethargicness, and irritability.
  • So watch out if you are a regular coffee drinker, consuming regular amounts of caffeine will make you at some point tolerant to it.
  • If you suddenly abstain from caffeine, you can guarantee you will have withdrawal symptoms. Irritability, brain bog, headaches, and exhaustion can last many days.

You have not mentioned Decaffeinated coffee. Should I revert to Decaf or stay with the regular?

The process of turning regular coffee into decaffeinated coffee is a simple one. The beans are repeatedly rinsed until nearly all the caffeine has been removed. It will still retain some levels of caffeine but at a much-reduced amount compared to regular coffee.

The drawback here for some of us, we can lose some of those positive health benefits that I mentioned earlier.

In a caffeine FREE conclusion.

Now, you know it is safe to have caffeine in your coffee. But, like everything in life always use a good degree of moderation. If you are unsure consult with your family practitioner.
