Whether in school studying for an impending examination or in the middle of a never-ending work day, there are times when we feel our systems shut down and we say to ourselves, “Yep, I need the strongest coffee in the world right now!” You are probably itching for that nerve-tingling jolt to snap you awake and reboot your brain.
The potency of coffee may be determined by a number of factors, but most people judge the strength of coffee by the caffeine kick they receive after their cup of Joe.
The soil where the coffee is grown, altitude of the area it is grown in, and species of coffee all make up for the different caffeine levels in coffee.
Here’s a small reference, the percentage of caffeine in Robusta coffee beans is 2.1% as compared to 1.2% in Arabica beans. Coffee grown under the shade will have half the amount of caffeine in contrast to coffee grown without shade, while some coffees are made stronger by producers who physically top up the caffeine levels of the beans with artificial additives.
Light Roast vs. Dark Roast Coffees – Which One is Stronger?
Most people believe the misconception that there is a relationship between the strength of coffee and the type of roast, which is, a light roast makes a weak coffee and a dark roast makes a strong coffee. This is in fact the opposite!
Light roast coffees are beans that have been roasted for a short amount of time. These beans tend to retain more acidity, are denser and filled with flavor of the country of origin. Since they are only on the fire for a short time, they hold on to most of the natural caffeine content that is lost during roasting, making them ‘stronger’. Light roasts have a mild taste that is focused on the bean’s composition, but not that much of a jolt.
Dark roast coffees on the other hand have a lower caffeine content, because the longer it stays on the grill, the more it disperses pure caffeine and other nutrients from the bean. Dark roast coffees have rich, bold tastes that show off the roast profile instead of the flavor of the bean, and are sometimes bitter.
The Method of Brewing Counts for Strength
The strength and essence of the coffee is highlighted during the brewing process. It’s fairly obvious that if you use an insane ratio of beans to water on any brewing method, you will get ‘strong’ coffee, but it will be harsh and unpleasant, and not necessarily good for your health.
Then again, cold brews require obscene amounts of coffee, but the extraction process is not as intense as an espresso which uses high pressure and a small amount of coffee. An espresso has more of a caffeine kick than French Press coffee. A French Press on the other hand, will release more caffeine than a drip coffee because it allows the oils from the beans to seep into the water at the right temperature.
When you find that your coffee tastes weak, is looking thin, or lacking in body, flavor, or sweetness, do not be quick to blame the beans. The brewing method you could be using may not be for that particular type of coffee, leading to an under-extracted beverage. When coffee beans are in contact with very hot water for too long, they tend to taste burnt, sour, or leave dark oily marks on the cup. To get the perfect cup of coffee, you may need to match your coffee maker with the right amount of coffee and the right amount of brewing time.
World’s Strongest Coffee
When searching for stronger- than- normal coffee to get you switched on again, you need to find coffee beans with a naturally higher caffeine content. There are a lot of brands that like to label themselves as “strong coffee“, but you don’t really get to notice the strength until after you’re done with what’s in your cup. We have narrowed it down to 6 coffees that have been rendered brutally strong and somewhat, borderline dangerous.
These 6 coffees have gone through chromatography tests to determine their caffeine levels. It is probably safer to let you know that according to the US Food and Drug Administration, 400mg is the safe daily limit of caffeine consumption, and 10g of coffee is considered a lethal dose. So while these strong coffees’ may just be the perfect wake up call, everything good has to be taken in moderation.
That being said, let’s jump into the list of coffee brands whose outrageous caffeine content puts them on the world’s strongest coffee register!
The Devil Mountain Coffee Company was not playing around when they created Black Label Coffee. Having sourced their premium coffee beans and roasting methods from exclusive plantations in Central and South America, the company boasts that their Black Label whole bean coffee has “a smooth and bold taste that’s roasted to perfection.” The company is USDA certified organic and practice fair trade.
Black Label tops the strong coffee list, with their coffee beans containing 1,555 mg of caffeine per 340 ml (12oz) brewed. According to them, Black Label is ‘so powerful, it’s a sin!‘
