RD1 Spirits' Latest Whiskey Expression Unites Sister Cities' Cultures in Limited Release

A Celebration of Craft and Culture: Award-Winning Straight Kentucky Whiskey Honors Lexington's Sister Cities Through Japanese Mizunara and French Oak Wood Finishing

LEXINGTON, Ky., June 4, 2025 /PRNewswire/ -- RD1 Spirits, the Kentucky bourbon brand known for pushing the boundaries of wood finishing, has introduced a limited release, Kentucky Straight Whiskey Finished with Japanese Mizunara and French Oak, that invites whiskey fans into a global conversation. The 2025 "Sister Cities" expression—a blend of 5- and 7-year-old bourbon with 8-year-old rye—is finished with Japanese Mizunara and French Oak, bringing together the American spirit of Kentucky whiskey with the wood character imparted from two different countries.

With a mash bill that starts in classic Kentucky tradition and finishes with an international perspective, this new release speaks to RD1's experimental ethos—and to its hometown roots. Lexington, Kentucky shares "Sister Cities" relationships with Shinhidaka, Japan and Deauville, France. The award-winning bourbon brand created a unique opportunity to honor these connections through innovation and wood finishing from both countries.

"We saw this as more than a whiskey experiment," said Jarrad Gollihue, PhD, R&D Master Distiller for RD1 Spirits. "It's a cultural expression. Japanese Mizunara and French Oak each bring their own subtle but complex influence and beautifully showcase the bold foundation of the Kentucky bourbon and rye."

In this Limited Release, Gollihue began with a 5-year-old bourbon (70% corn, 21% rye, 9% malted barley), matured in new, charred, American White Oak barrels. French Oak "necklaces" were added to the casks, extending maturation for a total finish time twice that of RD1's existing portfolio French Oak release. This finished expression was then blended with a 7-year-old bourbon (75% corn, 13% rye, 12% malted barley) and an 8-year-old rye (51% rye, 37% corn, 12% malted barley)— both well-aged, grain-forward spirits that added depth and contrast. The final step introduced lightly toasted Japanese Mizunara staves, which added delicate nuances of the wood's iconic character of sandalwood and incense.

RD1's latest Limited Release earned a gold medal and 95 points at the 2025 New York International Spirits Competition.

"For those of us who work to foster international connection, seeing a local distillery embrace our Sister Cities with such care and creativity is incredibly rewarding," said Kay Sargent, executive director of the Lexington Sister Cities Commission. "This new release speaks to the power of cultural appreciation, and how those values can be shared through something as iconic as Kentucky bourbon."
