For too long, when selecting a coffee solution for home, coffee enthusiasts had to either choose between a complex brewing method (quality over simplicity) or an overly simplistic method (convenience over quality). And none of them were beautiful. This was the impetus for starting Ratio back in 2012: to create a solution that married beauty, simplicity, and quality into a single experience.
