I tested this compact drip-coffee machine and it’s a fantastically fuss-free way to brew small batches of coffee — even if it can’t quite reach the intense flavor of more methodical processes
Ratio Four Coffee Machine Review: Small-Batch Drip Perfection
The Ratio Four represents a significant entry into the specialty coffee market, offering precision brewing in a compact package. This automatic drip coffee maker focuses on smaller batch sizes while maintaining the quality and design ethos that Ratio has become known for.
Design and Build Quality
The Ratio Four immediately impresses with its sophisticated aesthetic. The machine features a minimalist, bracket-shaped design that looks decidedly modern on any countertop. The matte black finish gives it a premium feel, and the overall footprint is surprisingly compact given its capabilities.
The construction quality is evident throughout, with heavy-duty components that feel built to last. The carafe, made from darkened, heat-proof glass, adds a touch of elegance while maintaining functionality. The filter basket is well-designed and accommodates both Ratio-specific filters and compatible Melitta options.
However, the water tank design is a notable compromise. The separate reservoir connects via an umbilical-style hose, which feels somewhat inelegant compared to the integrated tanks found in higher-end models. This design choice likely helps keep the machine’s footprint small, but it does detract from the overall aesthetic appeal.
Performance and Brewing
The Ratio Four excels in several key areas:
Brewing Speed: The smaller batch size translates to faster brewing times. While initial brews may take around 7 minutes, subsequent batches brew even faster once the machine is warmed up.
Ease of Use: Operation couldn’t be simpler – just add water, insert a filter, add grounds, and press the single button. The machine handles the rest, including an automatic bloom cycle that many competitors skip.
Consistency: The automated brewing process removes much of the variability associated with manual brewing methods, making it easier to achieve consistent results.
However, the machine does require some experimentation to dial in the perfect grind size. Users may need to test several batches to find their ideal settings, particularly when using different coffee beans or grinders.
Coffee Quality
The Ratio Four produces notably good coffee, though perhaps not quite reaching the heights of more hands-on brewing methods. The machine does an excellent job of extracting flavor without introducing bitterness, and the bloom cycle helps ensure even saturation of the grounds.
That said, coffee enthusiasts might find that pour-over or espresso methods can extract slightly more nuanced flavors from the same beans. The Ratio Four strikes a good balance between convenience and quality, but it may not satisfy those seeking the absolute pinnacle of coffee flavor.
Value Proposition
At $279, the Ratio Four sits in a competitive price bracket. While it’s more expensive than basic drip machines, it offers significantly better build quality and brewing performance. The price point makes it accessible to serious home brewers while still feeling like a premium product.
The machine includes everything needed to start brewing immediately, except for filters. This all-in-one approach adds to its value proposition, though users will likely want to invest in a quality grinder for optimal results.
Who Should Buy It
The Ratio Four is ideal for:
- Couples or individuals who typically brew 1-2 cups at a time
- Those who want excellent coffee without the fuss of manual brewing
- Users with limited counter space
- People who appreciate good design and build quality
Who Might Want to Look Elsewhere
Consider other options if you:
- Need to brew larger quantities regularly
- Prefer the ultimate in coffee flavor extraction
- Want a more traditional drip machine design
- Are on a tight budget
Final Thoughts
The Ratio Four successfully fills a niche in the coffee maker market, offering premium quality and design in a compact package focused on smaller batch sizes. While it has some minor drawbacks, particularly in the water tank design, it delivers excellent performance and produces consistently good coffee.
For those seeking a balance between convenience and quality, particularly in smaller households, the Ratio Four is a compelling option that justifies its premium price point through superior design, build quality, and brewing performance.
