The bourbon is crafting by marrying together no more than twenty casks of Kentucky bourbon, each of which has its own unique characteristics and flavor profile. In contrast to most small batch bourbons, the casks used to craft Noah's Mill have varying mashbills — while some casks are composed of bourbons that use rye as a secondary grain, others are composed of bourbons that use wheat as a secondary grain. The varying recipes — the percentage of rye and wheat used also varies among the casks — results in a layered bourbon that has a virtually unparalleled depth and complexity. After the casks of bourbon have been allowed to mature for up to 20 years, small batches of the bourbon are bottled at 114.30 proof. Noah's Mill Bourbon earned the Double Gold Medal at the San Francisco World Spirits Competition in 2012, and was "highly recommended" by F. Paul Pacult's Spirit Journal. In addition, it earned a score of 93 points from Jim Murray's Whisky Bible in 2012.
