Thirteenth Colony Distillery 15th Anniversary Cask Strength Bourbon 139.2 Proof

139.2 proof. Cask strength. Thirteenth Colony Distillery's 15th Anniversary expression — celebrating 15 years of Georgia craft bourbon production from the Americus distillery, bottled at one of the highest proofs ever released under the Thirteenth Colony label.

Thirteenth Colony Distillery is named for Georgia's designation as the 13th and final original American colony — a founding heritage nod from a distillery that has been rebuilding Georgia's craft spirits tradition since its establishment. The 15th Anniversary marks a decade and a half of production at a distillery that has become one of the Southeast's most recognized craft bourbon producers.

At 139.2 proof, the 15th Anniversary is the most powerful expression Thirteenth Colony has released — cask strength, no dilution, no filtration. For context: the previously optimized Thirteenth Colony Cask Strength Double Oaked is already a high-proof craft expression; the 15th Anniversary at 139.2 proof surpasses it significantly, approaching the territory of the highest-proof BTAC Stagg releases. This is Georgia bourbon at its most extreme and celebratory.

• Palate: Powerful and full — the 15th Anniversary cask strength delivering Georgia straight bourbon at its most extreme and celebratory.

Frequently Asked Questions

• How does the 15th Anniversary compare to the Thirteenth Colony Cask Strength Double Oaked? The Double Oaked is already a high-proof cask strength expression with secondary French oak maturation adding vanilla and caramel concentration. The 15th Anniversary at 139.2 proof is more powerful — surpassing the Double Oaked's proof significantly and celebrating the distillery's milestone without the secondary finishing. Pure cask strength at maximum celebration proof.
• Is 139.2 proof high compared to major cask-strength bourbons? Yes. At 139.2 proof the 15th Anniversary approaches BTAC George T. Stagg territory (135–144 proof range across vintages). It is one of the highest-proof straight bourbons from any craft distillery and the most powerful Thirteenth Colony expression commercially released.
• Is the 15th Anniversary still available? Yes — available now in limited quantities.
