Hillrock Solera Aged Bourbon is the first American whiskey to be aged in the centuries-old Solera method used traditionally to create exceptional Sherries, Ports, Madeiras, and Cognacs. Recognized internationally, the award winning whiskey is finished in 20 year old Oloroso Sherry casks which give the Bourbon floral notes layered with fig, roasted walnuts, candied fruit and spicy rye.

Solera aging involves a pyramid of barrels where a small portion of whiskey is removed periodically from the lowest tier of barrels and an equal measure of new whiskey is added to the top of barrels. No barrel in the Solera is ever emptied, and over time, the older whiskey in the Solera mingles with younger whiskies to create unmatched depth and complexity.

This bottling is a special release where the whiskey is then finished in Sauternes dessert wine casks.
