4 Simple Hacks to Maximize the Strength of Your K-Cup Coffee 

Have you ever felt that your Keurig brews lacked flavor? This is because the machine is designed to operate at fast speeds, and sometimes, it doesn't allow enough time for optimal extraction of robust coffee flavors.

Unlock the full potential of your Keurig with these easy tips to make stronger coffee that's sure to bring out its fullest flavor.

  • Push the "Strong" button to get your morning fix. Some Keurig machines provide a "Strong" feature that lets you enjoy stronger and fuller-bodied coffee with minimal effort. All it takes is pressing this one small button, extending your brew time to make flavorful cups of coffee each day. 

  • To attain the most delicious cup of coffee, always pre-heat your Keurig by running a hot water cycle without any pod included. This guarantees an incredibly flavourful brew and ensures that it is hotter than usual. 

  • Combining a single-use pod with a reusable one allows you to steep for twice as long and enjoy an even more robust flavor. You can also use ground coffee in your reusable pod for extra strength without compromising flavor. 

  • To achieve the richest cup of coffee, select the smallest setting on your Keurig. Not only is it important to get a desirable ratio with every pour, but selecting this option will ensure that you have an exceptionally strong cup of joe.  

Key Factors to Take into Account Before Making a Purchase 

When looking for the perfect K-Cup to satisfy your coffee cravings, you need to consider two definitions of "strength":

1. Caffeine content and
2. Taste.

Depending on how much coffee you want and what kind of flavor or kick comes with it will determine which product is best suited for your needs. Each Keurig machine has different cup sizes, so be sure to keep this in mind when making a selection.

When we talk about a cup of coffee being "strong," it can mean two different things. On the one hand, it generally refers to the taste; thick, bold, and rich, like an old-fashioned diner-style brew. But on the other hand, it could also refer to the amount of caffeine in each cup. Knowing which of these you're looking for is essential in finding your ideal K-Cup.

Once you decide which definition better suits your needs, then you need to consider how many cups of coffee you want. Are you looking for a smaller cup with plenty of caffeine or multiple cups with a stronger flavor? Depending on what type of strength (taste or caffeine) and serving size best fits your needs, you can narrow down your search.

Asking yourself those questions will help you make the right selection. Remember that each coffee machine has distinct cup sizes, so be sure to choose the K-Cup that is compatible with your machine. 


Without hesitation, my first choice is Death Wish K-Cups.

The fusion of Arabica and Robusta beans imparts an exquisite flavor that is smooth and full-bodied yet without a hint of nuttiness or earthiness.

Rich Robusta beans are smoother and less acidic than Arabica beans, so your coffee will be gentler on the digestive system.

An astonishing 728 milligrams of caffeine per 12-ounce cup. With this much energy-boosting power, one cup will keep you fueled and full of pep for a full day.

Ultimately, all the coffees on this list make great options; it's simply a matter of finding one that fits you best.
