Frequently Asked Questions
Find answers to common questions about our premium brewing systems
What makes Ratio machines different from standard drip brewers?
Ratio machines emulate a manual pour-over process using precise water temperature control and a unique bloom cycle, ensuring optimal flavor extraction without the manual effort.
Do I need special filters for my Ratio coffee machine?
Our machines are designed to work with custom-fit Ratio paper filters or our reusable stainless steel mesh filters for a full-bodied brew.
How do I clean and descale my machine?
We recommend using a mild descaling solution every 3-6 months depending on your water hardness to maintain heating efficiency and flavor purity.
Is the glass carafe thermal?
We offer both hand-blown borosilicate glass carafes for aesthetic clarity and double-walled stainless steel thermal carafes for extended heat retention.
Where are Ratio coffee machines manufactured?
Our machines are designed in Portland, Oregon, using premium materials like die-cast aluminum, hand-finished wood, and laboratory-grade glass.
Can I brew smaller batches than a full carafe?
Yes, our sensors automatically adjust the brewing parameters for smaller batches, though we recommend a minimum of 16oz for the best flavor profile.
