Kentucky Senator Bourbon Honors Champion Filly Nitrogen

Kentucky Senator Bourbon has launched its private-barrel Thoroughbred Legacy Series. The first release honors D.J. Stable’s champion filly Nitrogen, the favorite for the $2 million Longines Breeders’ Cup Distaff on Oct. 31 at Keeneland.

The 113-proof single-barrel bourbon, aged nine years, was selected and bottled by Potter Jane Distilling Company of Springfield, Ky. The proof matches Nitrogen’s highest career Beyer speed figure at the time of the release.

“Nitrogen’s name says it all,” said Andre Regard, the prominent equine attorney who co-founded Kentucky Senator Spirits with then-Kentucky Senate Majority Floor Leader Damon Thayer. “Even in her early training, Hall of Famer Mark Casse said that the filly ‘breathes different air,’ hence her name. She’s the perfect horse to kick off our Thoroughbred Legacy Series, which toasts Kentucky’s two iconic industries: horses and bourbon. As we say on the label of Nitrogen bourbon, ‘This private single-barrel bourbon pays tribute to Nitrogen’s fearless spirit, exceptional balance and championship heart. Like the filly herself, it is bold, refined and unforgettable.'”

More On Nitrogen

“We may never have another horse like Nitrogen,” said Jon Green, D.J. Stable’s general manager who owns the high-end breeding and racing operation with his father, Len. “Having a Nitrogen Legacy Series bourbon is one way to continue to celebrate and toast her for years to come. When trying to breed a champion, pedigree match-ups are so important. The same is true with business relationships, and it’s been great working with Kentucky Senator Bourbon. We’re honored to have Nitrogen as the first Legacy release, and our family looks forward to sharing Nitrogen Bourbon and the spectacular bottles with friends, clients, industry charities and for life’s unexpected special occasions.”

“The Legacy Series is ideal for promoting a cherished horse or equine operation, creating one-of-a-kind gifts for family, friends, partners or clients, as well as a fun and effective way to promote the bottle subject,” said Thayer, now a horse-racing adviser and advocate who spearheaded transformative legislation for both the bourbon and horse industries during his 22 years in the Kentucky Legislature. “We guarantee that every private barrel will be distilled, aged and bottled with care and passion as we create a fitting tribute for a beloved horse or property.”

About Nitrogen:

The 4-year-old has nine wins at seven tracks in 18 starts and more than $3 million in earnings. Her wins include the Grade 1 Ogden Phipps by 12¾ lengths, the Grade 1 Alabama and the Grade 2 Beldame on Sept. 25.

How the series works:

Legacy Series bottles are not sold to the public. They let racing industry clients honor a horse, farm or other equine subject. Each bourbon is aged at least six years, made in Kentucky, and customized with the honoree’s bio on the back label.
