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.
