We Take Our Coffee Seriously—But Don’t Just Take Our Word for It.
“It provides the alertness we desire from caffeine without the side effects like the dreaded crash, jitters, and anxiety that often follow. I am always highly skeptical about functional claims like this, but Rarebird does the trick.”
Andrew watman, wired review, october 2024

"This is why Jeffrey Dietrich founded Rarebird, which makes Px Coffee. It contains paraxanthine, a naturally occurring caffeine metabolite, instead of caffeine. As a result, it offers the taste and elevated mood and energy of coffee without any of the jitters."
MeiMei Fox, Forbes, February 2024

“Many people love coffee — and the energy boost they get from caffeine — but avoid it due to sensitivity to caffeine’s less-desirable effects, like jitters and heightened anxiety. Redefined from Rarebird is an entirely new take on coffee that swaps out caffeine for paraxanthine (Px), a natural metabolite of caffeine that provides a similar energy kick without caffeine’s nasty downsides”
Johnny Brayson, Gear patrol, August 2023

FAQs
Px Coffee improves your mood, focus, and sleep. It helps with focus and energy like caffeine, but without the jittery, wired feeling. Px breaks down in your body faster than caffeine, which lets you enjoy a cup in the afternoon or early evening without disrupting your sleep.
Many customers notice a difference after just a few cups. We recommend switching to Px Coffee for at least five days to fully experience its benefits to mood, focus, and sleep.
Here’s the science: Px is the primary metabolite of caffeine—your body converts about 80% of the caffeine you consume into Px. It doesn’t occur in plants like caffeine does, but it exists naturally in the human body.
We at Rarebird have developed unique technology with the help of the National Science Foundation to produce the first and only coffee that contains Px instead of caffeine.
No – Px Coffee looks, smells, and tastes just like traditional coffee, and is brewed just like traditional coffee. The only difference is that it contains Px instead of caffeine. It’s just two simple ingredients: Arabica coffee (with the caffeine removed) and Px!
We work with sustainably focused coffee importers to ensure the highest quality standards, ultimately providing you a cup that tastes as good as it makes you feel.
We start with a specialty-grade Colombian Arabica coffee, which is decaffeinated at the source using the Sugarcane process. This method is safe, environmentally friendly, and preserves the flavor exceptionally well. The coffee is then shipped to the US, where it is tested for mycotoxins upon arrival.
Px infusion and roasting occurs at our facility in California just before it's freshly shipped out to you.
We grind Px coffee to a medium grind for the most universal utilization. Whether you use a drip brewer, a pour-over, or a French press, this grind should be the perfect fit!
