“I am trying so hard to make this carafe work with the Ratio Six but am having a very hard time. The bottom line - in my experience the flow rate from the brewer is just too fast for the cone filter.
I have tried every kind of filter - Chemex, Hario large size, Able Kone - and none of them seem to be able to keep up with the flow. Not to mention the “bloom” feature on the Ratio is about a quarter of the full tank of water (I am generally making four cups) which is just too much.
I’m using a medium grind and am actually going to replace my old breville grinder so that I can start testing different grind sizes to see if that helps. But that’s the last in a long line of variables I can test. Hoping that works but I do feel like for a $500 machine it would be a little easier than this.”
“Open to updating this once I've gotten a better feel for the best setup; however so far my experience has been mixed. I am using the Carafe with a Ratio Six.
I'm finding that the rate at which the brewer sends water through the grinds is a lot faster than the filter allows through. As a result, the water gets backed up above the grinds and slips through the sides of the filter - resulting in weaker coffee. With the flat-bottomed filter this wasn't an issue.
Going to try different grind sizes and have also bought the Able Kone to see how that goes - but am a little disappointed in the initial performance considering the investment I've made in the kit overall.”
Hello Randy,
We'd love to help! In our experience the Kone does a better job of optimizing flow rate for tighter grinds. With the Chemex filter, we recommend going pretty coarse and perhaps bumping the dose up to 80 grams.
Let us know how it goes with the Kone!
“This replacement carafe is made of a thinner glass that feels like it is more likely to break than the original carafe that came with my ratio coffee maker. I would expect a thinner, lower quality carafe from a knockoff place, but I bought this directly from ratio.”
Sorry about this Samuel! We haven’t changed the glass wall thickness but there are innate differences from the hand blown process. We will dispatch a replacement to you. Thanks for letting us know!
