Great brewer made even better using the glass carafe. We were looking to replace an older Bonavita brewer with glass-lined carafe and tried a couple of other options before ordering the Ratio Six. We ordered the bundle with the glass carafe directly from Ratio and have had it for about a week now. After testing out different brewing options, here's where we landed on the options. We only drink dark organic roasts (highly recommend Alakef roasters) and always brew a full pot, so your results may vary. We had the best success with the same coarse/medium grind as we used with the Bonavita, and the recommended 70 grams of coffee for a full brew. ... Standard Ratio thermal carafe, flat-bottom basket, heat sheild. Produced a great cup of coffee, seemed smoother than the Bonavita, and stayed nice and hot for the 90 minutes or so we normally take to drink a pot. Unfortunately we didn't care for the taste in the stainless carafe after the coffee was in there for even a few minutes ... Glass carafe, Able cone, Chemex circle filter. The Able cone defintely seemed to allow more oils through and added some flavor, but the brew seems weaker than we prefer. Also definitely wasn't as hot when brewing completed and we put into our glass lined thermal carafe. ... Glass carafe, Chemex circle filter. Produced a stronger, darker flavor for us ... but still not as strong as the flat-bottom basket, and not as hot as we liked. ... Glass carafe, Chemex circle filter, heat shield. This was perfect combination for us and provided a surprisingly stronger flavor with the added heat shield. The heat shield definitely improved the brewing temperature through the filter and was enough of a difference to bring out the flavor of the coffee similar to the flat bottom filter. When brewing a full pot for 1-2 people using the glass carafe, you'll definitely want a thermal carafe to put the coffee in to keep it hot for more than just a few minutes ... so we're trying different options for that as we're using our old glass lined carafe for the moment. But it's great to have a plastic-free brewing option like this that also looks great and is super easy to clean afterwards. Highly recommend!

Love it! Was looking for a non toxic coffee maker, this checked every box. Coffee tastes better than my old coffee maker.

The Ratio Six Coffee Machine makes really great coffee, really fast. We have not had ours for long, so perhaps we will find issues, but none yet with the machine. I wish that Ratio had more information available about using this machine on its site, much of what we found was on YouTube (?) and that just seems silly. But so far, so good!

I’ve had a Technivorm Moccamaster 79112 KBT Coffee Brewer for over 10 years. In my opinion it makes the best coffee for a non-commercial coffee brewer. I thought I would give the Ratio Six a try since it got such amazing reviews. I’ve been using it for about 3 weeks now and these are my findings: 1. The coffee is very good, it is on parr with the Moccamaster so I’m pleased with that. 2. I like the design, being “Long” instead of wide and it fits on my counter better. 3. It feels more durable than the Moccamaster, but it does use more plastic parts. 4. It does not make as much coffee as the Moccamaster (40oz vs. 36 oz) 5. The Bloom function is amazing, but I think if the Moccamaster ever implemented that technology it would beat out the Ratio Six. 6. Major disappointment is that the thermal carafe does not hold the coffee at temperature very long. It cools off considerably after 2 hours while the Moccamaster thermal carafe holds it piping hot for longer. This would probably be the one reason that I would not recommend it to someone else. 7. My unit leaks water from somewhere, it is not coming out of the reservoir. When I fill it to the max fill line it stays that way over night, however when it is brewing it leaks out the bottom from somewhere. I’m not sure if It is condensation from the steam or if it is leaking out of the connection between the boiler and the drip nozzle. I did notice that drips do run down the inside of the tube in the reservoir and leave water droplets on the bottom of the reservoir. I always have to tilt the machine and let the water run out the bottom when finished. There is usually enough water to wet a paper towel.

Love the Ratio Coffee pot. It's easy to put together, easy to use, and makes the perfect temp coffee, without all the plastics touching the hot water like other machines.

Good coffee and a pleasure to use. High quality materials and very simple operation. Could be improved by adding a weighted rubber base to the brew pot tray which feels incongruously flimsy in comparison to the rest of the product and slides around on the counter.
