The fabrication of Maker's Mark involves a meticulously controlled process that emphasizes quality and tradition at every stage. The mash bill comprises corn (70%), soft red winter wheat (16%), and malted barley (14%). The soft winter wheat not only substitutes for the more commonly used rye, but it also gives Maker's Mark its signature sweetness and smooth character. Once the grains are milled, they are combined with water from the limestone-rich aquifers of Kentucky to create the mash. The fermentation process is carried out using proprietary yeast strains, which play a crucial role in developing the whisky's flavors.
After fermentation, the mash is distilled twice in a traditional copper pot still, which enhances the spirit's creamy texture. The distillation process culminates at a peak proof of around 105 before it is placed into barrels for aging. Maker's Mark is aged in new charred American oak barrels, a key element for imparting the deep color and complex flavors associated with bourbon. The aging process is monitored meticulously; rather than adhering strictly to a timeline, the distiller assesses the spirit to determine its readiness.
To ensure consistency in flavor, Maker's Mark employs a unique technique of rotating barrels throughout the aging process to promote even maturation. After the desired flavor profile is achieved, the whiskey is bottled at 90 proof (45% ABV) without chill filtering, which maintains its natural flavor integrity and presentation.
