Doc’s Rye goes through a unique process, borrowed from the Spanish sherry bodegas, the Solera method uses a pyramid system of oxidizing and influencing casks where a small portion of each barrel on the bottom of the pyramid is blended and bottled as a batch and then the whiskey that was removed from the barrels is replaced with a portion of the barrels above it. This is repeated for each tier of the pyramid. Only new spirit is added to the top tier to be cycled down over time. this method provides an ever aging product that lends complexity and consistency over time.
