Curious about the coffee types reserved only for hardcore enthusiasts? What sets apart a strong coffee, and how does it differ from your regular brew?
Buckle up and join TopListCafe on a journey to explore the world's strongest coffees, definitely not for the faint-hearted!
An Overview of the Impact of Caffeine
Coffee, the magical elixir, often hailed as the staple of millions worldwide. One of its major attractions is the brain-boosting effect of caffeine.
Once caffeine kicks in, it feels like an extra jolt of electricity coursing through your body and mind. Most of the world's coffee consumption happens in the morning, before studies and work commence.
The stimulating effects of caffeine typically kick in about 30 minutes after consumption. Essentially, your brain processes quicker, your body becomes more active, and your heart rate accelerates compared to before.
While caffeine isn't physically addictive, it can create a psychological 'dependency' for some. They often seek that alertness as a reflex before work, gradually forming a hard-to-break habit.
Certainly, there comes a time when your body starts feeling 'resilient' to the effects of caffeine. That's when you need to gradually increase the intensity, switching to a stronger coffee variant.
Strong coffee and instant alertness remain a forte for a significant portion.
3 Factors Determining the Quality of Strong Coffee
The concept of 'strength' in coffee varies from person to person. Some prioritize the drinkability of coffee, whether it's easy or hard to swallow depending on its bitterness. Alternatively, they gauge strength by the stimulating wakefulness effect.
However, what truly wins over many is the notion that strong coffee must possess the most 'extraordinary' effect from its caffeine concentration.
Note: The recommended caffeine intake for a healthy adult is 400mg/day.
So how does caffeine concentration get impacted and altered, stemming from various factors of a coffee type?
Choosing Coffee Beans
Raw coffee beans play a crucial role in determining the strength of the final brew.
Comparing the two most common types of coffee beans worldwide: Robusta, with an average caffeine content of 2.1%, nearly double that of Arabica's 1.2%. This is why most strong coffee products globally are made from Robusta beans.
However, don't think Arabica is just for show!
Unlike Robusta, Arabica is the ideal choice for high-quality coffee products in general, highly favored in the beverage service industry. Arabica's smoother flavor profile, due to its lower caffeine content, avoids drinks becoming excessively bitter and hard to control.
Coffee Roasting Process
Many have misunderstood two aspects of the coffee roasting process and its impact on the strength of the final product:
So what's the recommended roasting method to achieve the desired strength?
In reality, there's no consistent correlation between roasting time/temperature and the strength of coffee. It's all down to personal perception based on individual conditions and experiences.
Coffee Preparation Methods
Lastly, the brewing method also partly influences the strength or caffeine concentration retained in your coffee cup.
For Espresso, a one-shot cup contains about 60mg of caffeine. Meanwhile, manual pour-over coffee can contain an average of 100-120mg of caffeine per cup.
Pour-over coffee is the brewing method of choice for Ri in 'Crash Landing On You'.
The differing caffeine levels stem from the coffee extraction time:
By this calculation, cold brew coffee stands out as one of the methods yielding the highest caffeine content. 12-24 continuous hours is the duration for successfully cold brewing coffee beans using this method.
There are still other methods to push caffeine concentration higher as desired when preparing a cup of coffee. For instance, increasing the amount of coffee while keeping the water volume constant, or extending the extraction time (for Espresso machines).
However, don't overdo it as it may result in wasting coffee or making the flavor excessively bitter due to over-extraction. Nobody wants to experience such a 'heavy-handed' coffee enjoyment.
Top 4 Strongest Coffee Types Worldwide
Below are the brands and companies producing coffee with very high caffeine levels. They own and design a coffee processing procedure specifically tailored for this purpose.
The products and brands in the following list may vary in achievements, but overall, they are still globally renowned names leading the pack.
Death Wish Coffee
Death Wish stands as one of the pioneers in the strong coffee trend. Its current achievement reaches 728mg of caffeine per 350ml cup. The name of Death Wish resonates widely for its appearance in the iconic Superbowl commercials in the United States.
What makes Death Wish worth mentioning first is that despite its high caffeine content, it maintains a stable flavor profile (not as bitter as one might imagine). This product mainly targets athletes or 'night owl' customers who still want to be alert and diligent the next morning.
Death Wish doesn't disclose the details of their coffee bean formula, but it's said to originate from India and Peru. They also ensure the quality and caffeine content of their beans remain stable, tested through various meticulous processing stages.
Black Insomnia Bean Coffee
Originating from South Africa, Black Insomnia poses a heavyweight challenge to Death Wish. They even bluntly stated that Death Wish's caffeine content doesn't match its advertising claims and cannot compete with Black Insomnia's standards.
With an average caffeine content of 1105mg per 350ml cup, Black Insomnia lives up to its name, ensuring no one can fall back asleep after sipping on it.
Note: 1105mg is nearly three times the recommended caffeine intake for an adult.
Similar to Death Wish, Black Insomnia keeps its coffee formula tightly guarded, with no one knowing how they blend it or which variations of Robusta and Arabica beans they use.
It's known that Black Insomnia heavily invests in its roasting and bean processing technology. This leads to surprisingly diverse flavors of Black Insomnia, including options like caramel and hazelnut.
Biohazard Ground Coffee
Using exclusively Robusta coffee beans for processing, Biohazard Ground Coffee has achieved a result of 928mg of caffeine per cup.
Many experts have praised Biohazard Ground Coffee after tasting it. According to them, its flavor experience is smooth and easy to drink compared to the norm, even with such a high caffeine content.
Black Label Coffee (Devil Mountain)
Devil Mountain produces quite a variety of strong and diverse coffees, but Black Label remains their most famous version.
If this were a contest based on theoretical results, Black Label would surely secure the top spot. The caffeine content for a 350ml cup of Black Label reaches a staggering 1555mg!
One might think that the flavor of Black Label must be extremely bitter, but it turns out it's not. The coffee beans used by Devil Mountain originate from highland volcanic regions, crafting top-notch quality, enough to significantly reduce the unpleasant bitterness.
The Reasons Behind the 'Extraordinary' Caffeine Content
Not just you, many people share the same question: 'How can they produce coffee so strong?' Is there a downside, or some obscure method behind it?
In reality, these brands don't use artificial methods to add caffeine to their products. Instead, they invest in research to find the highest-quality coffee beans based on appearance, region, and climate.
Then, they innovate a standardized process to handle coffee, ensuring strict control over temperature and processing time. These are the two prerequisites that determine the final quality and caffeine content.
Above all, all these coffee types are licensed by the United States Department of Agriculture (USDA) and hold valid certifications in the market.
Is Drinking Strong Coffee Safe?
Certainly not for the faint-hearted, quite literally!
Those who are new to drinking coffee or consume it infrequently and lightly will have a high sensitivity to caffeine and may easily get caffeine jitters. When overdosing on caffeine, symptoms and uncontrollable bodily reactions can occur such as:
Another aspect to note is the taste of these strong coffees in the list above. They are refined to significantly reduce the inherent bitterness, becoming more akin to regular coffee.
This often leads many people to not be 'warned' about the true strength of the coffee when taking just a few sips initially. Everything only kicks in after the 30-minute threshold from the last sip, leaving them unable to resist.
Overall, strong coffee should only be used in dire moments when staying alert is paramount and no other options are available. Regularly consuming high amounts of caffeine poses a high risk of heart disease rather than bringing anything good.
Nevertheless, don't forget that coffee is an extremely beneficial beverage for health, proven with dozens of profound benefits in life! Just make sure you control the frequency and amount of your coffee intake.
