Can I return it if I don’t like it?

Absolutely. You have 30 days from receipt of your Ratio machine to try it out. If you decide it's not for you, we will issue you a full refund. To start the return process, visit ratiocoffee.com/return-warranty.


What is your warranty policy?

We have exceptionally generous (and long) warranty periods. Read more at ratiocoffee.com/warranty.


Is there a hot plate?

No. Adding heat to brewed coffee ruins the flavor within minutes. The Ratio glass carafe is thick, tempered borosilicate glass, and with the lid in place it keeps the coffee hot for about 15 minutes.


Will you have a thermal carafe?

Yes. We are in final production stages of our Thermal Carafe that will retain heat for up to 4 hours. The Eight can be used with the glass or thermal carafe interchangeably. Pricing and availability will be announced soon.


Are there any plastic parts?

FDA-grade silicone and a single BPA-free plastic component are used internally. The plastic we have incorporated into the Ratio Eight is medical grade quality. Made of polysulfone, this food-grade quality plastic is FDA certified and a NSF compliant material.
