Ultimate Guide to Coffee and Caffeine

Whether you keep a light hand on coffee or take a couple of shots after every few hours in a day, everyone has their personal sentiments attached to a cup of coffee. Still, it’s astonishing that most people don’t know about the drug caffeine. Our guide to coffee and caffeine will fill that gap. 

If you are a persistent coffee person, it’s more vital for you to know how much caffeine is in a coffee, let alone what amount of it is safe to consume. We understand that a cup of joe is an integral part of your day and you are addicted to its many benefits. However, understanding different types of coffee and their relation to caffeine is essential. 

This guide will tour you through the world of coffee and caffeine and how they both work in harmony to give you that perfect energizer you crave every morning. We’ll also be discussing some coffee types and how much caffeine they pack so you can tweak your preferences accordingly. 

How is Caffeine Different From Coffee? 

More than 90% of the world’s population consume coffee each day, while 50% of them prefer it in the morning to ward off their morning drowsiness and prepare the body to meet their challenging routines. This waking up aspect within your cup of coffee is all due to the drug caffeine in it, which has also probably earned it a similar name. 

Caffeine and Coffee are two completely different things. Coffee is a brewed drink made by straining water through grounded coffee beans. On the other hand, caffeine is a common psychoactive drug found in multiple substances other than just coffee, like carbonated drinks.

Being a psychoactive drug, caffeine influences normal brain functioning and alternates one’s mood and consciousness. The Food and Drug Administration recognizes caffeine as a legal drug as it does not cause a lot of harm to the bodily systems. However, it is addictive if consumed for a long time.

This means that any individual who consumes it in high doses can develop a physical and psychological dependence on caffeine. Here the good thing is that caffeine addiction is not as intense as the addiction to other drugs.

How Does Caffeine in Coffee Effects? 


When consumed in moderate amounts, caffeine’s advantages in coffee are not only limited to freshening you up in the morning and restoring focus. Caffeine induces an adrenaline boost to our system, providing our body with additional energy to handle daily mental and physical tasks. 

Moreover, coffee and caffeine are also powerful enough to affect the nervous, digestive, and cardiovascular systems. Not too much caffeine consumption has been shown to influence people with memory issues positively. 

The compound also improves an individual’s reaction time and critical thinking strength. Some more of the many health benefits of caffeine consumption via coffee include:

  • Reduce the risk of Alzheimer’s and Parkinson’s disease.
  • Regulates mood, anger, and aggression.
  • Minimized chances of heart attacks.  
  • Lower risk of Diabetes Type
  • Increased glycogen in muscles 
  • Reduced risk of oral cancer.
  • Aid in weight loss and fat burning
  • Enhanced endurance performance.
  • Reduced risk of liver cancer.

Side Effects

While stimulation via coffee seems nice when you can’t open your eyes in the morning, prolonged stimulation might turn the tables by getting too much on the mind and both. Excess of nothing, even the most beneficial substance in the world, is harmful, and so is the excess of caffeine. 

Addiction to coffee is not very damaging but not too light to ignore either. When you get used to receiving a regular excessive serving size of caffeine, your body crashes hard. And hence, any sudden unavailability of it causes withdrawal symptoms.

Coming to adenosine, the component that makes caffeine a vital source of reducing many harmful diseases can also cause potential damage to the brain’s blood flow. Surplus of adenosine tends to accumulate excess blood in the brain, causing nasty headaches that chronic coffee users are all too familiar with.

Hence, the most efficient way to reap only the advantages without facing all the caffeine hazards is to consume coffee regularly but in average amounts.

Things to Consider When Finding Coffee With Your Favourite Caffeine Content 

Now that you know what caffeine is and its potential effects on your body, it’s high time to understand critical factors that influence the caffeine content in coffee. Whether you like caffeine high, medium, or low, the factors mentioned below will help you choose your most suitable coffee. 

Type of Coffee Bean

There are multiple varieties of coffee beans around the globe; however, only two have remained the most popular amongst coffee lovers: Robusta and Arabica. You may be wondering, is there a difference between Robusta and Arabica? Sure there is! Both coffee bean types naturally contain different amounts of caffeine.

Arabica is the most popular type of coffee among the two. Due to its sweeter, more complex flavor, most coffee lovers recommend Arabica as it fits best for preparing black coffee. Even though it’s a more famous type of bean, Arabica doesn’t contain as much caffeine content as Robusta.

Maybe that means coffee enthusiasts aren’t all that crazy about caffeine than they are for a balanced taste. Coming to Robusta, it’s a much cheaper plus stronger type of coffee bean. Because of the bitter flavor, Robusta is generally utilized for espresso drinks and in instant coffee mixes. 

If you are that instant awakening shot lover, the full-of-caffeine Robusta beans will be a perfect choice. Their high caffeine content will never let you face drowsiness while you manage your daily chores with absolute focus.

Coffee roast also influences how much caffeine content your cup serves. It is roasting that turns raw coffee beans into the flavourful and aromatic coffee that wakes our senses in the morning. With that said, everyone has their go-to roast level, but if you are up to changing your choice depending on the caffeine content, it’s vital to understand the three roast types. 

The most common words to describe different degrees of coffee roasting are Dark, Medium, and Light. On light to medium roasting, caffeine slowly comes out from the bean’s heart resulting in a more rich mixture with an excellent coffee flavor. However, the more you roast, the more caffeine content burns out.

Therefore, if you want a more incredible caffeine punch, keep a light hand while roasting your coffee cause you don’t want the awakening psychoactive drug to drain off. Or else burn on medium heat to produce a drink that is neither too caffeinated nor less caffeinated. For those who want to keep caffeine as low as possible, dark roast is the right choice.  

Type Of Coffee 

Different types of coffee contain different amounts of caffeine. Meaning that the level of psychoactive dose a cup of joe provides can vary significantly between instant coffee, espresso, decaf coffee, or just a regularly brewed one.

“One cup of coffee” can range anywhere from 1–24 oz (20–700 ml), massively affecting the total caffeine content. The table below compares the amount of caffeine within 8 ounces (237ml) of each type of coffee made around the globe.
