The Splinter Group is a boutique American spirits brand that grew out of a collaboration between Napa Valley vintners and innovators looking to explore whiskey with the same artistry and care that goes into fine wine. Founded by John Schwartz of Amuse Bouche Wines, vintner Julie Atwood, and winemaker Bob Foley, the brand bridges the worlds of winemaking and distilling, crafting whiskeys that embody refinement, structure, and balance while maintaining a distinctly bold American character.

What sets The Splinter Group apart is its focus on finishing whiskeys in barrels previously used for premium Napa Valley wines. This crossover of wine and whiskey traditions adds unique layers of complexity, drawing on the richness and depth of Napa’s celebrated vineyards while preserving the heart of classic American whiskey. Each release—whether bourbon or straight whiskey—is blended with meticulous attention to detail, resulting in spirits that are smooth, expressive, and unmistakably distinctive.

The brand has developed a reputation for innovation, sophistication, and limited production, appealing to both whiskey collectors and wine enthusiasts intrigued by the marriage of two great crafts. The Splinter Group reflects a philosophy of collaboration, creativity, and respect for tradition, while pushing boundaries to create something truly original in the American whiskey landscape.
