What Is Caffeine Really?

Caffeine is a chemical that may be found not only in coffee but many other products as well including cola, tea, guarana, etc. Caffeine is most often used to increase mental alertness, although it has several additional uses. So, the question is, how does it work?

Caffeine acts by activating the central nervous system, the muscles, heart, and blood pressure control regions. Caffeine can elevate blood pressure, although it may not have this impact on those who use it on a regular basis. Caffeine is quickly absorbed from the stomach and into the bloodstream after ingestion. After that, it goes directly to the liver, where it brokes down into different chemicals that might influence the operation of numerous organs that we have already mentioned.

However, caffeine’s main effect is on the brain. It works by inhibiting the effects of adenosine, a neurotransmitter that helps relax your brain and makes you drowsy – that is the main reason why the amount of caffeine in coffee can be very important to some individuals.

In general, adenosine levels rise during the day, making you weary and wanting to sleep all the time. Caffeine keeps you energized by attaching to adenosine receptors in your brain but without activating them. As a result, all of these reduce tiredness in your body and brain.

What Influences The Caffeine Level of Your Coffee?

Caffeine is mostly known for its positive effects, however, it also can easily cause some negative consequences. For instance, caffeine use in excess might have long-term consequences on your health. High blood pressure, reduced bone density, and muscle twitching are some of the side effects.

Positive effects include decreased risks of cancer, dementia, and strokes. Additionally, caffeine has been demonstrated in tests to improve focus and memory on a daily basis. In order to control how much caffeine in coffee is, it might be a good idea to know what influences the caffeine level. To put it in a few words, there are 4 different things that affect the caffeine level

Bean Type

The coffee plant has several species, and different varieties of coffee grow best in different regions of the world. Coffee beans from various plants will differ in caffeine concentration due to differences in growth circumstances that impact the bean’s properties. Caffeine is naturally produced by coffee plants as a pesticide. These plants generate less caffeine at higher elevations because pesticides are less prevalent there. To make things more clear, let’s take a look at an example.

The world’s most popular bean types include Robusta and Arabica. So, Arabica grows at altitudes somewhere between 4200 and 5000 feet, while Robusta can thrive at a maximum of 2000 feet. Because of that, Arabica has far less caffeine in coffee compared to Robusta. However, it is also important to note that Arabica is considered tastier – In the end, it all comes down to your own preferences.

Roast Type

An important part of coffee lovers believes that dark roasts are stronger and have a higher caffeine content compared to light roasts. The fact, however, is that caffeine concentration remains rather constant throughout the roasting process. The difference in roasts is determined by flavor rather than caffeine content. According to this myth, the light roast has the most caffeine, then medium roast, and then dark roast.

Caffeine concentration in light roast and dark roast coffee is about similar when evaluated by weight. However, because the beans in light roast coffee are denser than those in deeper roasts, they contain somewhat more caffeine when measured by the scoop. Dark roasts contain less bulk since they are typically roasted for much longer.

All in all, caffeine in coffee is pretty counter-intuitive as you’d think that a darker coffee would have higher caffeine, but it’s something that many people are wrong about. But be careful with light roast coffees as they are pretty acidic.

Grind Type

When we talk about grind types, there comes a simple question. Can fine grind make a coffee that has more caffeine in it? The short answer is – Not precisely, but your brewed coffee will taste better and will be stronger if you ground the coffee finer.

The extraction is determined by the coarseness or fineness of the grind when you grind your coffee. The finer your coffee is ground, the more surface area the water has to work on the beans. As a result, finer grind results in more flavor extraction, needing less time for coffee to steep and you generally get a stronger cup of coffee.

However, some might want to get the highest caffeine coffee and in that case, there are some things to keep in mind. You should not over-extract as extra finely ground coffee will not only taste stronger, but it may also be harsh or gritty – not exactly something that you might want.

Brew Type

The way you make coffee is also important to its caffeine content. The thing is that caffeine can evaporate, so quicker and denser brewing methods produce the strongest versions. The French Press is great for making a strong cup of coffee quickly since a normal cup of coffee has the ability to produce 100 mg of caffeine.

That is the coffee with the highest caffeine on the list. Because of the continuous infusion in hot water, the flavors and chemicals of the coffee grinds are forcefully removed in this brewing technique. Furthermore, the longer the grounds are steeped, the higher caffeine content you are able to get. However, once again, you should not soak the grounds for too long or you’ll end up with bitter-tasting coffee.

Other than French Press, the Aeropress is also a popular choice for individuals who are always on the go. It creates up to 70mg of caffeine – as a result, you get rich and smooth coffee that is not excessively powerful because of the decreased caffeine levels.

So – What’s The Strongest Coffee Out There?

When you consider all of the many types of drinks available, you may begin to question which one carries the greatest punch. There are two approaches to determining the caffeine content of various beverages. It is either the caffeine in serving or caffeine per ounce.

Serving quantities vary based on the type of coffee consumed. Sometimes you drink 12 oz, and other times you only take a 4oz shot. So, in that terms, the strongest coffee can be nitro cold brew as with 16oz serving, you get caffeine levels somewhere around 300 mg, which is a lot.

If you’re more interested in how concentrated your caffeine is in your coffee, then it might be the best idea to look at how much it boils down to per fluid ounce. In this category, the best high caffeine coffee is clearly an Espresso. An ounce of espresso contains an average of 40mg of caffeine due to the way it is prepared. When compared to the others, this is a lot of caffeine in such a tiny volume of coffee.
