Death Wish Coffee Death Cups

Best Overall
Death Wish Coffee Death Cups
  • Roast Type: Medium-dark roast coffee
  • Flavor Profile: Smooth, dark, chocolate, cherry
  • Caffeine Content: Twice the caffeine level of regular K-Cups

Death Wish Coffee is certainly up there as a strong cup of coffee. Their beans contain twice as much caffeine as the average strong K-Cups. The high strength is thanks to the Death Wish coffee beans themselves, unlike many other brands that add caffeine.

Death Cups contain a blend of arabica and robusta beans. The robusta beans have twice the caffeine of a standard arabica. The arabica beans provide a silky smooth flavor. A winning combination for a strong, high-quality brew.

This K-Cup is for someone who wants the best of all worlds with their cup of coffee, someone who wants a strong, flavorful, and convenient coffee. 

It’s roasted in smaller batches to ensure high-quality beans. Death Wish Coffee has even been labeled a specialty coffee by the Speciality Coffee Association.

  • Roast Type: Dark Roast Blend

  • Caffeine content: Very high. Lower than Death Wish’s Death Cups

Here is another much-celebrated Death Wish Coffee K-Cup. It’s another coffee blend roasted in small batches of organic beans harvested from Indonesia, Central, and South America.

These Death Wish Coffee K-Cups were specially made for Black Label Society guitarist Zakk Wylde. It is a decadent beverage. A coffee for those who live a busy lifestyle and need a bolt of lightning through the system to keep them riding with the gods.




High Caffeine K-Cup Sampler Pack

Best Variety Pack
High Caffeine K-Cup Sampler Pack
  • Roast Type: Dark from each sample product
  • Flavor Profile: Rich, chocolatey
  • Caffeine Content: High, but not twice as strong as stated

This sampler pack features a variety of 50 different K-Cup pods from big coffee company names like Cake Boss, Guy Fieri, Double Donut, Shock, Red Eye, and Revved.

Whilst the manufacturer claims each pod contains up to twice the caffeine of competitors, these aren’t the strongest K-Cup Coffees available. Are they high caffeine coffees? Yes. Are they twice as strong as advertised? No.

Ideal for an office environment, giving your colleagues the freedom to perk themselves up with the brew of their choice. They’re also great if you want to refine your palette to see what you prefer if you’re new to coffee.

These are coffees to try out for a bit of variety as you go about your day.




Devil Mountain Black Label K-Cups

Strongest K-Cups
Devil Mountain Black Label
  • Roast Type: Dark roast
  • Flavor Profile: Rich, dense, full-bodied, savory
  • Caffeine Content: Extremely high, the strongest K-Cups on the market by far

Many coffee brands want to be the ones who make the strongest cup of coffee. Black Label by Devil Mountain may actually be the one. What we have with Black Label is a cup of coffee that produces around 51/2 times the amount of caffeine per cup when compared to a standard brew.

Caffeine has been added to this product, which is what gives it its sheer and unholy power.

For those who don’t enjoy a highly caffeinated coffee, this is the devil’s cup and should be avoided. For the devil-may-care types who need to wake the hell up, this is the one.

This is a coffee to bring out once in a while and show off to friends with. It could also be that lifeline if you’ve got a busy day ahead – or a hangover – and need to put the ultra caffeinated edge-on. This is not your regular coffee for the faint-hearted.

Best Bulk Buy
Green Mountain Dark Magic K-Cups
  • Roast Type: Very dark
  • Flavor Profile: Sweet, earthy, with subtle notes of dark fruit and cocoa
  • Caffeine Content: Less compared to other strong K-Cup coffees

This Dark Magic K-Cup coffee by Green Mountain offers a very dark roast but with a flavor that doesn’t overpower. And neither does the caffeine hit. Made from 100% Arabica, this coffee is a smooth ride with a smooth flavor considering the roast.

They are cost-effective and work well as a bulk buy product for those who want reliable cups of coffee on a regular basis. It’s an ideal brew for the family home or workplace to satisfy everyone’s taste and caffeine preferences with ease.




Folgers Black Silk Dark Roast K-Cups

Budget Pick
Folgers Black Silk Dark Roast K-Cups
  • Roast Type: Very dark
  • Flavor Profile: Intense, rich, and smokey with a classic taste
  • Caffeine Content: Less compared to other strong K-Cup coffees

A classic “cuppa Joe” brew. Quite often, strong coffee K-Cups come with a heftier price tag than their coffee pod counterparts. What Folgers offer here is a cheaper antidote to many other K-Cups. It’s a regular coffee in the best sense.

The caffeine doesn’t match the other strong K-Cups and its flavor isn’t complex. But this K-Cup is a reliable and safe bet for a daily brew. It’s a well-considered mix of arabica and robusta beans which makes for one chirpy coffee.

The agreeable price and agreeable nature of this coffee make it a good option for the office or busy work environment. Who wants complexity at work? It’s for people who want a no-nonsense Keurig coffee that doesn’t leave a bitter taste in the mouth or wallet.




Good Times Black Rhino Espresso Roast K-Cups

Boldest Pods
Good Times Black Rhino Espresso Roast K-Cups
  • Roast Type: Dark
  • Flavor Profile: Very rich, smokey, extra bold, powerful
  • Caffeine Content: Less compared to other strong K-Cup pods

The extra bold flavor and dark roast make you feel like you’re taking on the world in a head-on collision, much like the majestic black rhino…

The boldness of this coffee isn’t matched by the caffeine level, although the caffeine is still very much present.

This disparity between flavor and the level of caffeine works in its favor. It all adds up to a drink for those who want a coffee to knock their socks off but not their heads. A great coffee for midday or early afternoon coffee breaks that will wake you up but not keep you up.




Black Rifle Coffee Rounds

Best For Milk & Sugar
Black Rifle Coffee Rounds
  • Roast Type: Medium
  • Flavor Profile: Dark bittersweet chocolate, smokey, vanilla, cocoa
  • Caffeine Content: Twice the amount of a standard K-Cup

Welcome to flavor country!

A punchy bold flavor and punchy bold caffeine hit. It’s a high-quality product made from the large Colombian Excelso bean. The caffeine level is twice that of a conventional bean.

Black Rifle Coffee isn’t for someone who likes their coffee K-Cups to be gentle on the palate when black. It’s for someone who wants – or needs – a wake-up call in the morning. 

It’s a coffee akin to a drill sergeant. A good coffee to add milk or sugar to complement its bittersweet smokiness.




Shock Coffee Extra Strength K-Cups

Best Medium Roast
Shock Coffee Extra Strength K-Cups
  • Roast Type: Medium-dark
  • Flavor Profile: Floral, fruity, smooth finish
  • Caffeine Content: Up to 50% more than a standard coffee

A blend of arabica and robusta helps to make this a well-rounded coffee. It is medium-dark roasted with a good, strong caffeine kick.

The medium-to-strong caffeine hit of this coffee seems to chime with the medium-dark taste of the roast. Steady, but not overpowering.

It’s an easy-to-handle brew that delivers a quick hit for a steady buzz. It’s enough, but not too much if you need to focus throughout the day without jitters. It makes sense that it is used on over 350 American military bases worldwide…




Napalm Extra Dark Roast K-Cups

Best Dark Roast
Napalm Extra Dark Roast K-Cups
  • Roast Type: Extra dark
  • Flavor Profile: Bold, intense, earthy, fruity
  • Caffeine Content: High

It’s made from 100% arabica coffee whilst still packing a super-strong caffeinated punch. For an extra dark roast, it is full-bodied throughout and never bitter – certainly not as fiery as the name suggests.

This is a drink designed for those who perhaps struggle to awaken their senses at first light and need some extra bold, extra dark roast coffee encouragement to do so. Those who buy it will soon say they love the smell of Napalm in the morning.




How To Make the Strongest Coffee With K-Cups

Strongest K Cup Coffee - How To Make the Strongest Coffee K-Cups

The first and foremost way to get the most out of your high caffeine K-Cups is to buy the strongest coffee pods available. But there are also several ways to pull the optimal ultra caffeinated drink out of your coffee machine.

Preheat your coffee machine by running a blank through first

This should increase the water temperature by a few degrees and extract more coffee out of it.

Pull your drink away to avoid the last drops of water

It’s mainly water. You don’t want it to dilute your coffee if you want a strong one.

Double up your pods

Put the Keurig on the lowest ounce setting and run the water through with two different pods. This will make a stronger coffee than using only one K-Cup. It will also allow you to combine any two coffees you desire and make a mix of your own choosing!

Try reusable K-Cups

Reusable K-Cups give you greater control over which beans you want to use. If you grind your beans yourself you can have a fresher, more flavorful brew that packs a punch. Re-usable K-Cups allow you to pack in as many or as few coffee grounds to increase the strength of your brew.

What Is A K-Cup?

A K-Cup is a conveniently sealed cartridge of coffee that is compatible with Keurig single-serve coffee machines. K-Cups have not just succeeded in the single-serve coffee industry but dominated it.

So far Keurig has produced two versions of this machine: the Keurig 1.0 and Keurig 2.0. 

The difference between these two Keurig Machines is the cup sizes they can brew. The Keurig 1.0 can brew 4oz, 6oz, 8oz, and 10oz cups. The Keurig 2.0 can brew all these plus a 12oz or even 75oz beverage. 

K-Cups vs Coffee Pods

Strongest K Cup Coffee - K-Cups vs Coffee Pods

Both K-Cups and coffee pods are convenient ways of making single-serve coffees. K-Cups have overtaken coffee pods over the years, but coffee pods are still available and competitive in the industry. 

The key thing to know is that they aren’t compatible with each other.

What this all comes down to is preference. For a consistent quality coffee with a variety to choose from, K-Cups are the winner. For cost-effectiveness or eco-friendliness, choose a coffee pod.

Things To Consider When Buying The Strongest K-Cups For Your Coffee

If you want a strong, high-quality K-Cup like the ones shown above there are several factors to consider.

Single Origin vs Blends

A blend of coffees is often used to increase the caffeine without sacrificing the flavor. Brands will choose the highest strength arabica coffee from around the world to do so. Or they will make a mix of arabica and robusta to go even further.

Arabica vs Robusta

  • Arabica beans are the most common coffee variety due to their superior flavor.
  • Robusta beans have double the caffeine but their taste is less pleasant.

Coffee roasters will use a mix of arabica and robusta. The robusta will heighten the caffeine content whilst the arabica will improve the flavor profile to make a well-rounded coffee.

If you know what bean you’re choosing, the world of coffee gets more and more interesting.

Roast Type And K-Cup Strength

Strongest K Cup Coffee - Roast Type And K-Cup Strength

The 3 broad roast types are light, medium, and dark. Each roasting method affects the flavor profiles of the beans as well as the caffeine level:

  • Dark roasts – Smokey and bold, revealing deeper and darker flavors. This is due to the oil that surfaces on the bean as a result.
  • Medium roasts – A well-rounded profile. Often does well in preserving the unique flavors of a bean but with added caramel sweetness.
  • Light roasts – Bright and mellow with crisp acidity. Often lightly roasted in order to protect the unique characteristics and wide variety of flavors of the bean.

Roast types are similar with regard to caffeine levels. The difference is darker roasts have less mass which makes them lighter. This means that darker beans will have a higher caffeine content once they are measured by weight.

Because most K-Cups are a consistent 10g dose in weight, darker roasts should taste stronger and bolder.

Brewing Method

If you’re adding milk or cream you should pick a full-bodied coffee with a strong flavor as it will subdue the natural strength of your beans. 

For the strongest cup, we recommend drinking your coffee black. If that isn’t for you, you’ll be pleased to know the K-Cups we’ve reviewed are strong enough to withstand milk and sugar to provide the kick you’re after.

What To Look Out For When Buying Strong Coffee K Cups

There is less importance placed on the growing and processing methods with K-Cups as they are harder to discern. Vivid tasting nuances from growing and processing methods aren’t as visible.

What is often prioritized is the strength, boldness, and usability of these coffee pods.

Added Caffeine

K-Cups tend to be weaker compared to standard drip coffee, but this is quite unnoticeable.

Many of these high caffeine K-Cups achieve it by adding extra caffeine to the product.

If strong coffee beans have an unrealistic caffeine level, they will either have artificial caffeine added, or be a blend of arabica and robusta which is stronger.

Sustainability And Ethics

The Keurig K–Cup has come under scrutiny over the years due to the high use of non-recyclable plastic.

Things have changed recently. Since 2020, Keurig has dedicated itself to improving its reputation for its products’ recyclability.

They declared that all their products will be recyclable, although options will differ between buyers’ locations. Some brands also offer biodegradable products but they are uncommon.

Many K-Cups also get their coffee beans sourced from organic farms. It is important to check if the brand has a certified USDA certificate to make sure.

Some coffees also adhere to Fairtrade standards, so look out for any certifications to make sure.

Which Strongest K-Cup Coffee Should You Go For?

There are many factors to consider when it comes to picking strong K-Cups that suit your palate.

This can be impacted by the variety of beans used, their roast profile, whether they’re a blend, and much more.

Strong K-Cups are for those who want a bold coffee experience without the hassle. They work great in an office or busy environment, or in the family kitchen for when you want to grab a coffee with the click of a button before the day starts. There is real diversity available. 

In our review of the strongest K-Cup coffees, we found the Death Wish Coffee Death Cups are the best overall for a strong, smooth, and bold coffee.

If you favor rich flavor over strength you’ll want to go for the Valhalla Java Odin Cups. Many strong coffees excel with the buzz but let themselves down in the flavor department. That isn’t the case with Odin Cups.

Frequently Asked Questions

What Is The Strongest Tasting K-Cup Coffee?

Napalm by Good Times. Many bold coffees sacrifice the flavor quality for the strength value, but this isn’t the case with these K-Cups. Strong in flavor and strong in quality. 

Which Keurig K-cups Have The Most Caffeine?

Black Label by Devil Mountain. Be prepared with this one. Calling it a strong coffee isn’t enough. The caffeine packs one hell of a punch. These coffee beans are 5 ½ times as strong compared to the average cup of coffee. This is by far the strongest K-Cup coffee, more than enough to wake the hell up in the morning.

How Much Caffeine Is In A K-Cup?

There is less in a standard K-Cup compared to a drip or espresso, but it’s a different story with these strongest Keurig coffee cups, which have been specially chosen and roasted for their superior bold flavors and caffeine.
