enelope Bourbon Architect French Oak Stave Finished Straight Bourbon Whiskey - 750ml Bottle. The Architect is the new blueprint for the future of precision blending. The first build in this series combines our signature four grain mash bill with two styles of French oak staves. Working in collaboration with Tonnellerie Radoux of France, the market leader in oak barrel manufacturing and innovation, we selected each stave using their state-of-the-art OakScan process to construct a truly memorable flavor profile. After all, the best architecture leaves no room for error.
