The connection between music and spirits began with founder Jeff Duggan.
Jeff's life had long followed parallel tracks. He was a drummer, a lifelong music obsessive and an uncompromising believer in the warmth and dimensionality of analog sound. His studies in chemistry and computer science also gave him an instinct for experimentation and a need to understand how things work beneath the surface.
After founding Portola Coffee Roasters and helping advance specialty coffee in Orange County, Jeff turned his attention toward spirits. One question became the foundation for Stone Groove:
Could music do more than shape the atmosphere around a whiskey? Could its physical energy influence the spirit itself?
Jeff began investigating how sound, vibration, frequency and resonance could be introduced directly into the barrel maturation environment. What started as curiosity grew into years of experimentation, engineering and sensory evaluation.
That work became Musically Mastered™, Stone Groove's proprietary, patent-pending, two-stage whiskey-finishing process. Controlled sonic energy creates movement at the boundary between whiskey and oak. A second proprietary stage then promotes further integration, developing greater depth, smoothness, complexity and mouthfeel.
It is not music played casually near a barrel. It is not generic vibration or ultrasonic aging, and it is not intended to replace the role of time. Musically Mastered™ is a purpose-built process combining acoustics, fluid dynamics, barrel chemistry and sensory development.
We describe it this way: The original distillate is the studio track. We engineer the final song.
Each musical genre carries its own sonic signature. Those different patterns of energy allow us to explore how a spirit responds as it is finished. The whiskey is not flavored by music. It is physically shaped through it.
Our obsession with music does not end at the DJ booth. It extends into the way we create our spirits.
