HILLROCK 'SOLERA AGED' BOURBON

"Hillrock Solera Aged Bourbon is the world's first solera aged bourbon. Solera aging is a process that has generally been reserved for aging cognacs, ports and sherries. It involves filling a series of casks at different intervals over a long period of time. As whiskey from the oldest cask is emptied and bottled, the cask is re-filled with an equivalent amount of whiskey from the second-oldest cask in the solera. This cascading effect continues until the youngest cask in the solera is filled with new whiskey. As a result, no cask in the solera is ever fully emptied. In addition, as the younger whiskey ages and cascades through the solera, its average age and complexity gradually increases over time."
