On The Rocks Cocktails (OTR) was founded with the mission of bringing bar-quality cocktails into a ready-to-drink format without compromising authenticity or flavor. Launched in 2015 in Dallas, Texas, the brand quickly gained recognition for using premium spirits from well-known distilleries, blending them with natural ingredients to create cocktails that mirror what you’d expect from a skilled bartender.

Each expression in the lineup is crafted to highlight the character of the base spirit—whether it’s Knob Creek® Bourbon in the Old Fashioned, Hornitos® Tequila in the Margarita, or Effen® Vodka in the Cosmopolitan. By collaborating with respected spirit brands, OTR ensures consistency, credibility, and high quality across its portfolio.

Now part of the Beam Suntory portfolio, OTR Cocktails continues to expand its reach globally while maintaining a focus on craftsmanship, convenience, and authenticity.
