Maximum Power. Zero Harshness.

Index 4 is our strongest, robusta-dominant coffee, engineered to fuel your most demanding tasks. It delivers high-output energy for deep work, long days, and intense, espresso-forward routines—all with a rounded, smooth finish.

What to Expect from Index 4:

• High-Output Energy: Our most potent blends, designed for peak performance and sustained focus.
• Engineered Smoothness: We meticulously roast to eliminate the burnt, bitter edge often found in very strong coffees.
• Precision & Control: With Know Your Dose™ caffeine ranges on every label, you can manage your intake with confidence.

Control Your Energy. Know Your Dose™

Radical Transparency is Our Standard: We lab-verify and publish the caffeine range for every coffee, right on the bag. How you brew matters—your grind, water ratio, and method all tune the final dose. Our transparency gives you the power to dial in your energy with precision.

Smart Consumption: As a general guide, up to ~400mg of caffeine per day is considered appropriate for most healthy adults. Since personal sensitivity varies, the best approach is always to listen to your body.
