A darker roast lets the coffee taste come through loud and clear. It's our boldest STōK yet. More Beans & Caffeine. We put more Arabica coffee beans in the brew than regular STōK. More beans, more caffeine, deeper coffee-first flavor. Want a darker roast? This is your STōK. If you drink coffee because you like the taste of coffee — this is your STōK. We use even more Arabica beans, dial up the roast level and let our Low & Slow® cold-brew method unleash the flavor. You'll taste chocolaty, nutty, caramel notes. Or maybe just gutsier cold brew. That's StōK Extra Bold — like an eagle stalking its dreams at midnight. Still Smooth. We brew it Low and Slow® — our dark roast beans are brewed at lower temperatures and steeped for 10 slow hours for a smooth taste that's never bitter.
