From the Storm to Your Cup

Thunder Mule is born in the electric heart of Chiang Mai's highlands — where mist clings to the peaks and lightning cracks across the sky. I source only from these misty mountains because the high altitude, cool air, and rich volcanic soil force the beans to develop slowly, intensely, and with unmatched character.

Every roast is a strike of power: glossy, oily beans that deliver thick, tiger-striped crema and a deep, lingering taste of dark chocolate, caramel, and hazelnut. The caffeine hits hard and clean — no jitters, no crash, just pure, unstoppable energy.

The Thunder

Flavor notes: intense dark chocolate, smooth caramel, nutty hazelnut. Level of roast: Vienna dark, bringing out glossy, oily texture. Bean size: screened to 18 mesh for uniform, premium whole beans. High caffeine for that real horsepower in a cup — energy that lasts without the crash.

Why Chiang Mai Highlands Make the Best High-Caffeine Dark Roast Beans

February 02, 2026

I'm not here to sell you hype. I'm here because I found something real in Chiang Mai's misty mountains and I can't shut up about it. At 1,200–1,700 meters, the air is cooler, the mist hangs longer, and the soil is volcanic-rich. That forces Arabica trees (especially Peaberry) to ripen slowly — packing more sugars, acids, and caffeine density into every cherry. The result? Beans that roast up glossy and oily, with explosive dark chocolate, caramel, and hazelnut depth you don't get from lowland or mass-produced lots.

Screened to 18 mesh, roasted fresh by Hillkoff, this Vienna dark roast hits hard on caffeine without bitterness or burnout. It's not "just coffee" — it's horsepower in a cup from actual highland farmers who still pick by hand. If you're tired of flat, generic dark roast that fades by lunch, this is the wake-up call you've been missing.
