Frequently Asked Questions
Everything you need to know about brewing the perfect cup with Ratio.
What makes Ratio coffee machines different from standard drip makers?
Ratio machines emulate a manual pour-over process using precision hardware. They feature a unique bloom phase and laboratory-grade glass or thermal carafes to ensure optimal flavor extraction without the complexity of manual brewing.
How long does shipping take for domestic orders?
Standard shipping typically takes 3-7 business days within the continental United States. Once your order ships, you will receive a tracking number via email to monitor your delivery status.
What is your return policy?
We offer a 30-day return window for all Ratio machines. If you are not completely satisfied with your purchase, the item must be returned in its original packaging with all included accessories to qualify for a refund.
Do Ratio coffee machines come with a warranty?
Yes, every new Ratio Eight and Ratio Six machine is backed by a 5-year limited warranty covering manufacturing defects and hardware malfunctions under normal home use.
Which payment methods do you accept?
We accept all major credit cards including Visa, Mastercard, and American Express, as well as digital payment options like PayPal, Apple Pay, and Shop Pay installments.
How do I clean and maintain my Ratio machine?
We recommend descaling your machine every 3-6 months depending on water hardness. The carafe and filter basket should be rinsed after every use, and the exterior can be wiped down with a soft, damp microfiber cloth.
