Bourbon’s return in popularity has prompted a more in-depth examination of the actual science in its manufacturing. Discover how the best bourbon processed achieved its great taste.

This article delves into the scientific procedure and technology of shifting grains and a mash of corn to one refined characteristic.


Productions’ first procedure is to grind the grains to produce grist. They will transfer the grist into a mash cooker or run, where it needed to be mixed with water, after which is the heated process labelled as mashing. Grains are separately poured one at a time at the right temperature. Although grains containing large amounts of starch, the required yeast for fermentation will only process glucose. Consequently, the process of mashing will aid in liberating glucose from starch.


When starch has been cleared of sugars, the mixture is cooled and transferred to a fermenter from a mash tun with yeast. Facilities with the recycling process will continue to cool water for the best batch of mash.

Sweet and sour are the mash produced by the distiller. The sweet bourbon mash only consists of yeast and water. In comparison, in the sour bourbon mash, parts of the water are supplied with a stillage that is the fluid amount that stays from the earlier removed alcohol distillation. Because of the existence of an acidic solution set throughout fermentation, a setback is sour. Both procedures can provide excellent bourbons; however, there is an argument among distillers as to which is the best, the sour or sweet mash.


The distiller’s beer is put to the still once fermentation is complete. Pot stills, which distil a single, relatively small batch, and column stills, which distil continuously, are the primary types of stills.

Barrelling and the aging process

While the distillation is legally permitted to be distilled till 160 proof, it should reach a fresh, charred oak barrel at no more than 125 proof. As a result, the distillate is diluted before entering the barrel. The clear, colourless distillate has only a fraction of the taste and none of the final bourbon’s brownish amber hue. The barrel and aging procedure have a considerable impact on the ultimate flavour, smoothness, and colour. Chemical extraction, chemical interactions, and evaporative loss occur throughout the aging or maturation, generally taking at least four years.

Bottling and consumption

After maturing, a distiller can mix numerous barrels to preserve a consistent depth of flavour or bottle from a single barrel. Bourbon is only bottled at a proof higher than 80. In many situations, they will add water to the bourbon to dilute it to the appropriate strength and taste profile. Some makers and drinkers prefer ones that have been bottled at cask strength, which is often more than 110 proof.

The final stage in the procedure is, of course, to make a drink of the best bourbon. The topic of whether to drink bourbon straight, with a bit of water, or even on the rocks is a contentious one.

Both experiences and research tell you that the way you taste your bourbon affects the flavour, as do all of the distiller’s actions during the production process. It is up to individuals who embody the spirit of molecules to make the most significant judgments that result in the best experience.
