“Did not work properly. Sent it back. Would not run brew cycle unless you unplugged/repugged the machine. You did try and help but nothing worked. You also offered to send me another machine. No complaints with customer service but I could not get the machine to work.”
“The brewer works fine, but it’s ridiculous that Ratio does not include any filters, not even a starter pack of a few, with a machine that costs hundreds of dollars. I literally couldn’t use the brewer for weeks because I could not get filters. Ratio makes it prohibitively expensive to order their filters and as far as I can tell don’t give any information about appropriate sizes or brands other than the nameless Ratio ones. I initially ordered some Ratio filters from Amazon, but the shipment was delayed, then randomly cancelled. Then I thought I’d order from Ratio, but they charge $10 to ship a pack of filters that costs $9.95, how does that make sense? Very poor customer service. So be sure to order plenty of filters when you order the machine otherwise you will be waiting a long time to make it work. By the way, so far the Amazon Basics filters (~$3 for 100 and shipped free with Prime) are working fine — I’d like to know if they are equivalent to the Ratio filters but I have not been able to get those…and I don’t know if there are any other filters Ratio would recommend, which would be helpful.”
“Bought the Ratio 6 because of good reviews. I'm happy to add to those. Attractive system that is easy to use and clean, but it brews the best cup of home-brew coffee I've ever made. Highest praise.”
“This machine works as advertised but has a learning curve. I use it with the Ratio 8 S2 stainless dripper to minimize hot water plastic contact and to make it easier to clean. I've had it for a couple of weeks and finally dialed things in. I had quite a lott of trouble with airlock/overflow, where the filter wouldn't let water through. This was a combination of the filters I was using (Melitta brown and white) and my grinder producing a lot of fines. Even the ratio branded filters didn't quite help. Bunn filters did the trick.
Anyway, it's a beautiful machine and I enjoy watching it do its thing each morning. Be aware that the brew guide may mention the 2 cup line as 500ml of water; it's actually 390ml according to Ratio customer service.”
“I purchased a refurbished Ratio Six with the stainless dripper/catcher, which replaces the stock filter basket, as well as a brew mat. TL;DR - everything works as promised, but there is a learning curve. If using paper filters, use Bunn.
I was confused from the website copy and got the impression that I needed the brew mat to take advantage of the stainless dripper, but this turned out not to be the case; it's only needed if you are using the machine with some other brewing equipment like a chemex. The fit of the stainless basket on the thermal carafe has a bit of play, but it's really nothing that concerns me and hasn't affected my brewing. I am happy to be plastic free for the entirety of the hot water pathway (less the lid of the thermal carafe, which I can accept).
It took me close to a pound of beans to dial in my brew with this machine, for a few reasons: first, nobody out there apparently is pairing my grinder (Capresso Infinity) with this machine, so I was grinding too coarse for a while even though various comments online said I would need a coarser grind than expected because the machine is so effective at extraction. I am currently on the Fine-4 setting of that grinder and getting good results (it has 4 settings each within Extra Fine, Fine, Medium, and Coarse, for a total of 16).
I also had a bunch of filter airlock happening. First I used Melitta brown filters. Then Melitta white filters. Then I called Ratio and they suggested Bunn filters, and also sent me a 100-pack of their Ratio filters. The ratio filters did as poorly as the Melittas, but Bunn has been 100%.
Also, the brew guide I was sent must have been an earlier version - it incorrectly lists the 2-Cup water line level as corresponding to 500ml. Ratio support confirmed it is actually 390ml, so adjust your ratios (ha) accordingly.
I am using 26 g with 390ml, 38g at 650, and 53g at 975ml/6 cup line (the last one per the guide). Results have been good, but I have only brewed with Costco Mexico Oaxaca single origin, which is a dark medium, so YMMV.
This is my first "advanced" coffee machine, having previously used a basic Cuisinart programmable 14-cup machine or an Aeropress. I definitely miss the ability to schedule the machine turning on by itself, and for the time being I am the only person in my house who can make coffee, so this is definitely an enthusiast machine. If you aren't willing to learn how to operate a grinder and measure out beans at some point, this machine isn't for you. I was really happy to see that they sell refurbished units, so I can minimize the environmental impact of owning the machine. Support has been responsive via phone and website chat. Website AI assistant noticeably less useful.”
