Barrell Whiskey DSX1 Mash&Grape Private Release is a specific private selection release from Barrell Craft Spirits in collaboration with the retailer Mash&Grape. It is a unique edition of their whiskey that is exclusive to Mash&Grape.

The specific details of the DSX1 Mash&Grape Private Release, such as the age, mash bill, and flavor profile, would be specific to that release and may not be readily available in my database. Private releases like this are often hand-selected and curated to offer a distinct flavor profile that aligns with the preferences of the selecting party.
