Gentleman Jack is indeed a sour mash bourbon. In fact, it is a straight (unblended) sour mash bourbon, which means that it meets the legal requirements for bourbon and also goes through the sour mash process.
The sour mash process is a traditional method used in bourbon production to ensure consistency and quality in the final product. It involves using a portion of previously fermented mash, known as “backset,” to start the fermentation of a new batch of mash. This backset helps to control the pH levels and provides a consistent environment for yeast fermentation.
Gentleman Jack’s sour mash bourbon is made with a higher proportion of corn, which is the primary grain used in bourbon production. This higher corn content contributes to the sweet and smooth character that is often associated with bourbon.
In addition to the use of corn, Gentleman Jack also uses proprietary yeast strains in its fermentation process. Yeast plays a crucial role in converting the sugars in the mash into alcohol, and different strains of yeast can contribute to the flavor profile of the final product. The use of proprietary yeast strains allows Gentleman Jack to have a unique and distinctive taste.
Another interesting aspect of Gentleman Jack’s production is its large multistory warehouses. These warehouses, numbering over 50, provide ample space for aging the bourbon barrels. The aging process is essential for bourbon as it allows the spirit to develop complex flavors and aromas over time. The multistory warehouses create variations in temperature and humidity, which can impact the maturation process and contribute to the overall character of the bourbon.
Furthermore, Gentleman Jack undergoes a charcoal filtering process for finishing. This involves passing the bourbon through charcoal filters, which helps to remove impurities and further refine the flavor. The charcoal filtering process in Gentleman Jack takes approximately 10 hours, ensuring that the bourbon achieves optimal clarity and smoothness.
Gentleman Jack is a sour mash bourbon that incorporates a higher proportion of corn, proprietary yeast strains, and undergoes charcoal filtering for finishing. These factors contribute to its unique taste and character, making it a beloved choice among bourbon enthusiasts.
