A bourbon mash invoice is the recipe for the grain combination used to make bourbon whiskey. It should include no less than 51% corn, and the remainder of the grain will be rye, wheat, or malted barley. The mash invoice will decide the flavour and aroma of the bourbon.
The significance of a bourbon mash invoice can’t be overstated. It’s the basis of the whiskey’s taste profile and may vastly affect its general high quality. Totally different mash payments will produce bourbons with totally different traits, so it’s important for distillers to fastidiously contemplate the grain combination they use.
