“So far I absolutely love my Ratio Eight series 2. It makes remarkable coffee and has fabulous curb appeal. I rate it at 4.5 out of 5!”

“The ratio 4 coffee brewer is a morning routine game changer! It's almost too easy. The separate water resovoir is genius. No more spilling water all over the coffee machine. I prep the coffee in the evenings and all I have to do when I wake up is walk into the kitchen and hit the brew button. And four minutes later I have an incredible cup of coffee. And I have a cup leftover to take to work in my travel mug so I don't have to stop at the big green mermaid anymore. If you're a single person like me it's honestly the perfect coffee setup. Saves me time in the mornings and it's already saved me a ton of money. My only complaint is the coffee isn't as hot as other brewers I owned in the past but that one small negative is greatly outweighed by all the positives of the Ratio 4.”

“My Ratio Four coffee machine is beautiful. It makes my coffee experience delightful. There are just a couple of things that I have to get used to. For example, when I first removed the basket to take the coffee grinds out, the hot coffee that remained in the basket came out from the bottom and went on my hand. The other thing is the power button, it is in a spot that is easily touched when putting the basket back in place. Other than that, I love the Ratio Four coffee machine.”

“Great machine, but get the thermal carafe, the glass one isn't great, coffee gets cold too quickly”

“I clumsily shattered my previous Ratio Glass Carafe on a marble counter and I needed a replacement for my Ratio 8. I do hope Ratio will continue to offer these for Ratio 8 (and Ratio 6) machines, as I much prefer the Chemex style cone filter to a basket style filter for automating my pour over process!”

“I saw one of the Ratio coffee makers at a coffee shop while traveling and it's been on my mind ever since!”

“Review: The Ratio 8 Coffee Maker — Where Biohacking Meets High Design For years, I was fiercely loyal to my stainless-steel French press. It was simple, ritualistic, and produced delicious coffee. That is, until I listened to Dr. Rhonda Patrick explain how unfiltered coffee, French press, boiled, and espresso, contain diterpenes, oily compounds that can raise LDL cholesterol and other lipids, potentially increasing cardiovascular risk. Her fix was refreshingly simple: use a paper filter. An unbleached, non-toxic one, of course. And so began my search for a healthier coffee maker. Easier said than done. I hadn’t realized how challenging it would be to find one that didn’t quietly leach microplastics. Weeks later, after endless fine print and near misses, I landed on the Ratio 8 S2: arguably the most expensive non-espresso coffee maker ever made, but also the most exquisite. It’s gorgeous, all sculptural lines and hand-blown glass. But beyond beauty lies brilliance: a precision-engineered pour-over system. The result? Cleaner coffee, still rich in polyphenols, without the diterpene drama. Yes, the Ratio 8 is indulgent (I waited for a sale). Each morning now begins with a moment of beauty, and truly delicious coffee, design meets intention, with a healthier heart in mind.”
