Distillers have been producing whiskey for centuries. From the beginning of the distilling industry, those who crafted the whiskey stills would use animal fat to keep the whiskey at a steady temperature. As time went on and the recipe changed, they switched over to using a combination of tallow and lard to create the substance we know as whiskey. However, there are still times when the use of animal fat is found on the label.
A major problem for those looking to purchase products that are produced by distillers comes from mixing up the history of the bourbon distiller with that of the Kentucky bourbon. There is no relation between the two. While the Kentucky distillers do make a whiskey from the mash of the bourbon mash, it is not what is used to create bourbon. In fact, the bourbon mash is commonly known as rye whiskey because of the rye used in the making process. Many of the other distilleries on the east coast simply do not follow the path that the original distiller did. The bourbon distilleries in Kentucky make their own rye whiskey, and some use corn to create their products, but the bourbon they produce comes from the mash of bourbon mash.
Because of the differences in the two products, the cost of making bourbon in a distiller can vary. The amount of work involved in making a whiskey may also vary. A distiller may use animal fat in the process of creating the bourbon, or they may use more traditional and non-animal methods to create their products. If the decision has been made to purchase products from a distiller, then it is important to research the processes and ingredients they use.
