Keurig Coffee Machines: A Comprehensive Review

Straight to the Point

Keurig machines may not be the first choice for coffee aficionados or those concerned about environmental impact, yet their ease of use and quick brewing time attract many casual coffee drinkers. For those looking for a reliable option, I found the K-Supreme Single-Serve Coffee Maker particularly appealing. Its compact design allows for convenient storage, and it offers the ability to brew both iced and hot coffee. Another budget-friendly option I suggest is the K-Mini, known for its space-saving capabilities.

I confess, I’m no coffee expert. While I appreciate the intricacies of brewing and enjoy well-crafted coffee, I often struggle to remember the specifics behind a good brew. Despite my kitchen perfectionism—some would say obsession—with precise measurements and tools like my probe thermometer, I find myself lost when it comes to brewing methods, often needing to consult guides for coffee-to-water ratios. My coffee struggles are particularly embarrassing, as I pride myself on my culinary skills.

What I am absolutely familiar with is the necessity for coffee in my daily routine. Although I consider myself a morning person, my energy levels drop significantly by noon without sufficient caffeine. This is where the convenience of the Keurig brewer shines. Despite previous criticisms from us at Serious Eats regarding their grind consistency and the single-use plastics they employ, these machines can still deliver a decent cup of coffee that many casual drinkers find satisfactory.

In my quest to identify the best Keurig coffee makers, I evaluated seven different models priced between $60 and $200. I assessed machines that only brewed hot coffee alongside those equipped with special features like built-in milk frothers and internal chilling systems for iced coffee. Key considerations included the amount of counter space each machine required, the quality of the coffee produced, and any additional functionalities. While all the Keurig models performed adequately, I pinpointed two standout machines based on their user-friendliness and value for the money.

The Winners, at a Glance

The K-Supreme features a sleek design capable of brewing coffee in sizes ranging from six to twelve ounces. It also includes a strong brew setting and the option for brewing over ice, adding versatility to its functionality. Adjustable water tank placements enhance its adaptability to various kitchen layouts.

The K-Mini simplifies the brewing process with a user-friendly button system. This model eliminates a conventional water reservoir, requiring only the needed water for each individual brew. Priced under $100, it stands out as one of the most economical choices among Keurig machines.

The Tests

Throughout the testing process, I explored various feature-rich models, assessing their hot coffee capabilities as well as specialty features. Various tests included:

Medium Roast Coffee Test: Evaluating brewing time for an eight-ounce cup using a popular medium roast coffee pod.
Dark Roast Coffee Test: Repeating the process with a dark roast K-Cup.
Special Functions Test (Winners Only): Utilizing additional capabilities of the top performers, such as iced coffee brewing and milk frothing.
Cleaning and Usability Tests: Assessing the ease of cleaning and overall user experience of each machine.

What We Learned

Keurig Machines Aren’t for Connoisseurs, But They Were Consistent

Overall, the Keurig machines delivered surprisingly uniform coffee quality across models. The brewing process involves forcing pressurized water through coffee pods, significantly reducing brewing time. Experts note previously mentioned drawbacks of these machines, including their inherent inability to replicate the quality of freshly ground and roasted coffee beans. Many K-Cup pods contain pre-ground coffee, which can become stale over time. Additionally, the standard brewing temperature is set just below the optimal range, affecting flavor extraction and resulting bitterness.

Despite the drawbacks, countless options for K-Cups are available. Well-known brands and numerous independent roasters participate in providing a vast array of inserts. Throughout my testing, I established that coffee brewed from the same pod maintained an astonishingly similar taste, regardless of whether it was made in the compact K-Mini or the more advanced K-Cafe SMART. While the Keurig machines may not extract the most desirable flavors from every coffee, their performance with medium and dark roast pods yielded acceptable and even enjoyable results.

Brew Sizes and Features Varied

The varying capabilities of Keurig machines were key in distinguishing their performance levels. Most machines could brew between six and twelve-ounce cups, but models such as the K-Classic were limited to ten-ounce servings. Variations in features, like the ability to brew over ice, were also notable, as some models excelled with specific brewing tasks.

The Cost of K-Cups Can Add Up

While the convenience of K-Cups is undeniable, they can result in higher overall costs. For instance, the medium roast K-Cups used in testing totaled approximately $0.51 per pod. In contrast, the equivalent ground coffee cost approximately $0.34 per cup. Costs for K-Cups vary based on preferences, yet, for someone brewing one cup daily, this routine could accumulate to around $61 annually, purely from using K-Cups.

Coffee Pods Aren’t Very Recyclable

Environmental factors must also be weighed when considering Keurig machines. K-Cup pods, made from number five polypropylene plastic, technically are recyclable if properly cleaned, but the reality is that many do not end up being recycled. Data suggests that the recycling rates for K-Cups are alarmingly low, and misleading claims from the company regarding their recyclability have led to legal repercussions.

The Criteria: What to Look for in a Keurig Coffee Maker

The general appeal of Keurigs remains robust among many households due to their speed and ease of use. Testing revealed that all machines could brew a cup in under three minutes, with minimal cleanup required afterward. Although alternatives may be cheaper and produce less waste, Keurig’s unbeatable convenience serves those with limited time and mobility. When considering a Keurig, the best approach is to choose a model that fits your budget, preferred brew size, and necessary features, taking note of options for customization such as brewing strengths and temperatures.

FAQs

Are K-Cups recyclable?

While it is theoretically possible to recycle K-Cups, the actual processing rates remain abysmally low. Consult your local recycling facility regarding their ability to handle K-Cups, as acceptance does not guarantee processing.

How do you descale a Keurig?

Regular descaling is crucial for maintaining your machine. Depending on usage, descaling should be performed every three to six months using the right solutions for your model.

How do you make iced coffee from a Keurig?

Fill a cup with ice and brew your coffee pod over the top. Certain models, like the K-Supreme, include special settings that provide a well-balanced iced drink.

Does a Keurig make espresso?

While Keurig machines can create coffee pods akin to espresso, they lack the required pressure to produce traditional espresso. For authentic espresso, consider a dedicated espresso machine instead.
