This is an outstanding cask strength rye whiskey. From the aroma to the flavor, it encompasses a variety of notes that any whiskey enthusiast would appreciate. 13th Colony has mastered the technique of highlighting oak in their rye whiskey, likely due to the addition of wood spirals during the production process. In addition to their single-barrel offering, 13th Colony also sells a standard rye whiskey called ‘Southern Rye.’ This whiskey is non-age stated (NAS), but it is rumored to be aged between 4 to 6 years and bottled at cask strength.
