Ready to drink and canned for your convenience, this addition to our Px Coffee line serves as an excellent way to enjoy our signature coffee in your home or on the go. It offers the jitter-free energy boost, improved focus and better sleep you've come to love from Px Coffee.
Just like our flagship Px Coffee, each can contains 60mg of Px. While we recommend chilling before enjoying, Px Cold Brew is shelf stable and can go with you to work, the beach, and anywhere in between.
Stress-Free Energy
Unlike caffeine, Px Coffee won’t spike stress hormones like cortisol and adrenaline.
Instead of leaving you jittery and wired, it provides smooth, focused energy that works with your body—not against it. No stress overload, just clean, balanced alertness.
Beat the Burnout
Caffeine gives you a temporary boost, but over time, it wears you down — creating a cycle of dependence and exhaustion.
Px Coffee helps you stay energized without overstimulating your nervous system, so you can power through your day without running on empty.
Better Restful Sleep
Px metabolizes faster than caffeine, so it won’t linger in your system and disrupt your sleep.
That means you can enjoy coffee during the day without sacrificing deep, restful sleep at night. Wake up feeling truly refreshed.
Exceptional Taste
Great coffee should taste as good as it makes you feel.
We source high-quality beans and roast them to perfection, so you get the same rich, full-bodied coffee experience you love—with a smarter caffeine alternative.
Voted Best New Product by the Specialty Coffee Association in 2023, this is a brew you can depend on.

What are the benefits of Px Coffee?
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.
How soon will I notice a difference with Px Coffee?
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.
What exactly is Px?
- 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.
Will Px coffee taste different than traditional coffee?
- 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.
How is Px Coffee made?
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.
