From the distiller:
Where the Surf Meets the Turf at Del Mar
"At Maker's Mark, our wood-finishing series was created to explore new, unique expressions of our signature whisky. Beginning as fully matured Maker's Mark® at cask strength, Private Selection is created by adding 10 custom wood finishing staves to each barrel. It's then aged in our limestone cellar to extract a unique, flavorful taste profile. Participants in this special barrel program get their say in the selection of these wooden staves. The finishing staves can be any combination of five flavor profiles chosen especially for this program. With 1,001 possible stave combinations, each expression of Private Selection has a customized finish and taste profile that is unique, yet undeniably Maker's®. Maker's Mark® Private Selection is available in select markets and also at our distillery."
