The production of Green Brier Tennessee Hand Made Sour Mash Whiskey begins with a carefully selected mash bill, notably featuring a high proportion of corn complemented by wheat and malted barley. The grains are milled and then combined with water to create a mash, which is heated to activate enzymes and convert starches into fermentable sugars. The mash undergoes fermentation for several days using proprietary yeast strains, allowing yeast to convert sugars into alcohol, resulting in a lively wash with potent flavors. Once fermentation is complete, the wash is distilled in traditional pot stills, ensuring elements of craftsmanship are retained in the spirit's character.
Following distillation, the spirit is filtered through a mellowing bed of sugar maple charcoal, enhancing the flavor profile and smoothing the final product. It is then aged in new charred oak barrels for a minimum of four years, a practice that imparts deep color and rich, complex flavors as the whiskey interacts with the wood. Each barrel is carefully selected and monitored, ensuring consistency and quality throughout the aging process. Finally, the whiskey is bottled at a robust 45.5% ABV, providing a true representation of its heritage and craftsmanship.
