It Started With a Crash

We loved coffee, but coffee didn’t always love us back. After that second or third cup, we’d feel shaky, anxious, and drained instead of energized. So we tried matcha, the ceremonial green tea of the samurai, said to bring calm focus even before battle. And it worked.

The difference was life-changing: instead of a caffeine spike and crash, matcha gave us sustained clarity.

But we missed coffee: the aroma, the grounding ritual, the feeling of home in a cup.

We set out to create a new kind of coffee: one that brings you the best of both worlds.

The Science Behind It

Let’s start with the dry science real quick:

(1) “L-theanine, an amino acid found in green tea, blocks the binding of L-glutamic acid to glutamate receptors in the brain. This leads to anti-stress effects by inhibiting cortical neuron excitation. Both L-theanine and caffeine have been shown to improve cognition and mood.” (Source: Yoto et al., Journal of Physiological Anthropology, 2012)

What does this mean for you as a Zennith drinker?

You get all the energizing benefits of caffeine—without the downsides.
No more jitters, no more crashes. Just clean, focused energy you can trust.

And it gets better:

(2) “The combination of moderate levels of L-theanine and caffeine significantly improved accuracy during task switching, boosted self-reported alertness, and reduced feelings of tiredness.” (Source: Giesbrecht et al., Nutritional Neuroscience, 2010)

And even further:

(3) “Subjects showed faster reaction times, better memory performance, and reduced mental fatigue—all while feeling more alert and less tired.” (Source: Giesbrecht et al., Nutritional Neuroscience, 2010)

In short:
L-theanine + caffeine = calm, focused, sustained energy.

No crash. No jitters. Just flow.

The Samurai’s Secret to Sustained Energy

We fell in love with the story of matcha, the high-grade green tea that samurai would drink to find clarity before battle.

Inspired by this tradition, we began drinking matcha daily and experienced firsthand the grounded, focused energy it brings.

But we couldn’t let go of coffee—the ritual, the aroma, the comfort.

We asked ourselves:
What if coffee could offer that same calm, focused clarity?

We dug deep into the science behind matcha’s magic.
The answer was clear: L-theanine.

Studies showed that when L-theanine and caffeine are combined, the result is an extraordinary state of calm focus—energy without anxiety, alertness without overwhelm.

So we set out to create a coffee that could deliver that same life-changing clarity.
And we did.
