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 simulate a manual pour-over process using precise water temperature control and a unique bloom cycle that allows coffee grounds to settle for maximum flavor extraction.
How long does shipping take for my new machine?
Orders are typically processed within 1-2 business days. Standard shipping within the continental United States usually takes 3-7 business days depending on your location.
What is your return policy for Ratio products?
We offer a 30-day return policy for unused products in their original packaging. Please note that a restocking fee may apply, and return shipping costs are the responsibility of the customer.
Do Ratio coffee machines come with a warranty?
Yes, all Ratio Eight and Ratio Six machines come with a 5-year limited warranty covering manufacturing defects and mechanical failures under normal home use.

The Ratio Eight uses Chemex-style paper filters or our custom stainless steel reusable filter, while the Ratio Six is compatible with standard flat-bottom basket filters.
