Keurig K-Mini Plus Detailed Review
The Keurig K-Mini Plus immediately impressed me with its incredibly small footprint. It’s truly less than 5 inches wide, making it a perfect solution for those notoriously small kitchen spaces, dorm rooms, or even office desks where every inch counts. Despite its minimalist design, this little powerhouse still offers the convenience of Keurig K-Cup pods, brewing any cup size between 6-12oz. I particularly appreciate the strong brew button, which genuinely delivers a more intense cup for those mornings when I need an extra kick. Plus, the clever pod storage unit that slides into the brewer itself, holding up to 9 K-Cup pods, is a game-changer for keeping things tidy. And yes, it’s happily travel mug friendly, which is essential for my on-the-go mornings.

- Integrated pod storage unit is a smart, space-efficient addition.
- Simple, straightforward operation with no unnecessary frills.

Cons

Expert Opinion: “The Keurig K-Mini Plus excels in its commitment to minimalism without sacrificing the core Keurig brewing experience. Its strength lies in its incredible compactness and the handy pod storage, making it ideal for the most constrained spaces.”
Keurig K-Slim Detailed Review
Moving on to the Keurig K-Slim, I immediately noticed its equally slim and sleek design, maintaining that desirable less-than-5-inches-wide footprint. What truly sets the K-Slim apart in my experience is its Multistream Technology. I’ve found that this feature genuinely makes a difference, extracting a fuller flavor and aroma from the K-Cup pods, resulting in a noticeably richer brew. This, combined with the multiple cup water reservoir – a generous 46 oz. capacity that lets you brew up to 4 cups before refilling – significantly ups the convenience factor. I also appreciate the flexibility of being able to brew 8, 10, or 12 oz. cups with just the push of a button. It still delivers fast & fresh brewed coffee in minutes, which is what we all love about Keurig.
Key Features
- MULTISTREAM TECHNOLOGY: Extracts full flavor and aroma in every brew.
- FITS ANYWHERE: Less than 5 inches wide, perfect for small spaces.
- MULTIPLE CUP WATER RESERVOIR: Removable 46 oz. reservoir lets you brew up to *4 cups before refilling.
- BREWS MULTIPLE CUP SIZES: brew an 8, 10, or 12 oz. cup at the push of a button.
- FAST & FRESH BREWED: Coffee made in minutes.
Pros
- MultiStream Technology delivers noticeably better flavor.
- Large 46 oz. reservoir minimizes frequent refilling.
- Multiple brew sizes (8, 10, 12 oz.) for versatility.
- Maintains a slim profile, ideal for small counters.
- Quick brew time.
Cons
- Slightly less portable than the K-Mini Plus due to the reservoir.
- No “Strong Brew” button like the Mini Plus (though MultiStream helps with flavor).
- Higher price point than the K-Mini Plus.
Best for:
Individuals or small families who value enhanced coffee flavor and the convenience of a larger water reservoir, while still needing a compact coffee maker that doesn’t hog counter space.
Expert Opinion: “The Keurig K-Slim elevates the slim-brewer experience by integrating MultiStream Technology and a substantial reservoir. It’s a fantastic option for those who want better flavor and less frequent refilling without sacrificing precious counter real estate.”
keurig k mini plus vs k slim: Key Differences That Matter
When comparing the keurig k mini plus vs k slim, several critical differences emerge that can genuinely influence your daily coffee routine and overall satisfaction.
Performance Comparison
In my testing, the most significant performance difference comes down to flavor extraction and reservoir convenience. The K-Slim’s MultiStream Technology is not just marketing hype; it genuinely results in a more evenly saturated coffee puck, yielding a richer, more robust flavor profile compared to the standard brew from the K-Mini Plus. While the Mini Plus has a “Strong Brew” button, the K-Slim’s regular brew with MultiStream often felt more consistently flavorful to me. Brew speed is comparable for a single cup, both being very quick.
Price/Value Analysis
Generally, the K-Mini Plus is the more budget-friendly option. It offers exceptional value for its simplicity and space-saving design. The K-Slim, being a step up with MultiStream Technology and a larger reservoir, comes at a slightly higher price point. In terms of value, if enhanced flavor and less frequent refilling are high priorities, the K-Slim justifies its higher cost. If strict budget and ultimate compactness are your main drivers, the K-Mini Plus provides excellent value.
Build Quality Comparison
Both machines feel sturdy for their price points, constructed primarily from durable plastics. The overall build quality for both is what you’d expect from Keurig: functional and reliable. The K-Mini Plus’s integrated pod storage unit is a nice touch for decluttering, but it doesn’t necessarily impact the core build. The K-Slim’s larger, removable reservoir feels solid and securely fits onto the machine. Neither feels premium, but both are built to withstand daily use.
User Experience Differences
This is where the practical aspects really shine.
* Refilling: The K-Mini Plus requires you to add water for every single brew. This can become tedious if you drink multiple cups or have guests. The K-Slim, with its 46 oz. reservoir, allows for 3-4 brews before needing a refill, which is a huge convenience factor in daily use.
* Brew Sizes: Both offer a 6-12 oz range. The Mini Plus technically allows for any amount within that range (by filling its one-cup reservoir), while the K-Slim offers specific 8, 10, and 12 oz buttons. This comes down to preference – do you want to choose an exact amount of water, or rely on pre-set buttons?
* Maintenance: Both are easy to clean. The K-Mini Plus’s single-cup reservoir is quick to wipe out. The K-Slim’s larger reservoir is also easy to remove and clean, but being larger, it might require a bit more attention to prevent mineral buildup over time.
Which Should You Choose?
Deciding between the K-Mini Plus and the K-Slim ultimately comes down to your personal priorities for convenience, counter space, and coffee quality.
If you are a solo coffee drinker, have incredibly limited counter space (like in a dorm, small apartment kitchen, or a dedicated desk setup), and truly value the absolute smallest footprint, the Keurig K-Mini Plus is your champion. Its minimalist design, strong brew option, and integrated pod storage make it perfect for simple, single-serve convenience on demand. It’s also the better choice for those on a tighter budget looking for a reliable Keurig experience without frills.
However, if you appreciate a richer, more nuanced cup of coffee, desire the convenience of brewing multiple cups without refilling for each one, and don’t mind a slightly higher initial investment, then the Keurig K-Slim is the superior choice. Its MultiStream Technology makes a noticeable difference in flavor, and the 46 oz. reservoir is a game-changer for daily use, especially if you brew more than one cup a day or share your coffee maker. It still maintains that desirable slim profile, making it a fantastic blend of space-saving design and enhanced functionality for the modern coffee drinker.
Final Verdict: For ultimate compactness and budget-friendliness, go with the K-Mini Plus. For a significant upgrade in flavor and everyday convenience with its larger water reservoir, the K-Slim is well worth the extra investment, making it my personal recommendation for most users.
Frequently Asked Questions
Q: What is the main difference between the keurig k mini plus vs k slim?
A: The main differences lie in their water reservoirs and brewing technology. The K-Mini Plus has a one-cup reservoir that needs refilling for each brew and a “Strong Brew” button, while the K-Slim features a 46 oz. multi-cup reservoir and Keurig’s MultiStream Technology for enhanced flavor extraction.
Q: Does the K-Slim truly make better-tasting coffee due to MultiStream Technology?
A: In my experience, yes. The K-Slim’s MultiStream Technology, which saturates the coffee grounds more evenly, consistently produced a richer and more aromatic cup compared to the standard brew from the K-Mini Plus.
Q: Which machine is quieter when brewing?
A: Both machines are relatively quiet for Keurig brewers, but I found the K-Slim to be slightly less noisy during the actual brewing cycle, though the difference is minimal.
Q: Can both the keurig k mini plus vs k slim fit a travel mug?
A: Yes, both the Keurig K-Mini Plus and the K-Slim are designed to be travel mug friendly. Their drip trays are removable to accommodate taller mugs.
Q: How often do I need to descale these brewers?
A: Keurig generally recommends descaling their brewers every 3-6 months, or more frequently if you have hard water. Both the K-Mini Plus and K-Slim have indicator lights that will alert you when it’s time to descale.
Q: Is there a significant size difference between them, given they are both “slim”?
A: Both are less than 5 inches wide, so horizontally they are very similar. The K-Mini Plus is slightly shorter and has a more integrated look due to its lack of a large external reservoir, making it feel marginally more compact overall, especially for packing or moving.
Q: Does the K-Mini Plus really store pods inside?
A: Yes, the K-Mini Plus comes with a unique, removable storage unit that slides neatly into the brewer itself, holding up to 9 K-Cup pods, which is a great space-saving feature. The K-Slim does not have this integrated storage.
