I've seen the specs on this machine. They sent me an access code for the full site after I requested one here:
ratiocoffee.com/access
So, go for it! Also, I got quick, detailed answers to a few questions when I posed them via email to Mark Hellweg.
I imagine "ratio" refers to the fact that the machine "automatically determines the amount of water you've added to the tank and adjusts the brewing time accordingly." It won't tell you how much ground coffee to add though.
The carafe is custom, designed to work with Chemex paper filters or the Able Kone. You'll be able to use a Chemex in place of the carafe with the help of a conversion kit.
Ratio is asking for people *not* to share images or access codes via social media, but I'm happy to partially answer questions without posting huge copy/paste chunks of info. until the site goes public.
