The first legal distillery in Hardin County since Prohibition — a family-owned craft operation near Fort Knox with military-themed bourbons, a natural limestone spring, and walk-in tours every day.
Boundary Oak is a pleasant surprise on the bourbon trail. Tucked in the knobs of central Kentucky near Fort Knox, this family-owned craft distillery uses natural limestone spring water from a 100-year-old oak tree on the property to distill small-batch bourbon, whiskey, and moonshine.
The military connection runs deep here — Radcliff sits right outside Fort Knox, and the distillery's American Spirits Collection pays tribute to figures like General Patton and Abraham Lincoln (born in nearby Hodgenville). Their "Armored Diesel" and "Lincoln Straight Bourbon" aren't just marketing gimmicks — the stories behind them are genuinely interesting, and military visitors especially appreciate the connection.
Tours are self-guided with a short film that starts at the bottom of each hour, followed by a tasting. The vibe is relaxed and personal — you might be the only visitor, and the staff takes their time walking you through their full lineup. The tasting is one of the best values on the trail, and several visitors report spending far longer than planned because the staff is so engaging.
Boundary Oak is conveniently located between Louisville and Bardstown, making it an easy add-on when driving between the two main regions. It's also just 15 minutes from Jim Beam in Clermont.
Self-guided tour with a short film on American spirits history, followed by a guided tasting of their popular lineup including Old Kentucky Home, Patton Armored Diesel, Cinnful 69, and moonshine. Walk-in friendly, no reservation needed. One of the best deals on the trail.
An elevated tasting featuring their top-shelf spirits including St. Michael, St. George, War Eagle, and limited releases. Comes with an etched rocks glass. Worth it if you want to explore their full range beyond the flagships.
Boundary Oak is one of the easiest stops on the entire trail. Walk-in tours run all day, every day. No reservation needed. Large groups of 15+ should call ahead, but everyone else can just show up. You might have the place to yourself on a weekday.

The gift shop has their full lineup of spirits at reasonable prices — several bottles are under $30. The military-themed bottles (Patton, Lincoln, 82nd Airborne) make unique, meaningful gifts that stand out from standard bourbon souvenirs. Their Cinnful 69 cinnamon whiskey is a crowd favorite and a fun bottle to bring home. The staff is knowledgeable and happy to help you pick based on your taste preferences.
Boundary Oak is the definition of an unexpected gem. It doesn't look like much from outside, but the personalized experience, affordable tastings, and unique military-themed lineup make it a rewarding stop — especially if you're driving between Louisville and Bardstown. The walk-in format and proximity to Jim Beam make it an effortless add-on. Active duty military receive free tastings, which is a classy touch.
