'''Sour mash''' is a process used in the distillation of [[whiskey]] that involves using material from an older batch of mash to start the fermentation of a new batch. This technique is similar to the process used in [[sourdough]] bread making, where a starter is used to begin the fermentation process.

	==~~History~~==		== Process ==
	The origins of the sour mash process are not well-documented, but it is believed to have been developed in the early 19th century. The technique was likely adopted to improve the consistency of the product and to make the fermentation process more reliable. Dr. James C. Crow is often credited with refining the sour mash process in the 1830s, making it a standard practice in the bourbon industry.

	~~==Benefits==~~		The sour mash process begins with the creation of a "mash," which is a mixture of [[grain]], [[water]], and [[yeast]]. In the sour mash method, a portion of the mash from a previous distillation is added to the new mash. This "backset" or "setback" helps to maintain a consistent pH level, which is crucial for the fermentation process.
	The sour mash process ~~offers several benefits to distillers:~~
	* '''Consistency:''' By using a portion of a ~~previous batch~~, ~~distillers can achieve~~ a ~~more consistent product from batch to batch~~.
	* '''Flavor:''' The acidity of the sour mash ~~can lead to~~ a ~~more complex flavor profile in~~ the ~~final spirit.~~
	* '''Efficiency:''' The acidic environment of the ~~sour~~ mash helps to ~~prevent the growth of unwanted bacteria~~, ~~making~~ the fermentation process ~~more efficient~~.

	~~==Bourbon and Sour Mash==~~		The addition of the backset also helps to control the growth of unwanted bacteria and ensures a consistent flavor profile in the final product. The sour mash process is particularly important in the production of [[bourbon]] and [[Tennessee whiskey]].
	~~While~~ the ~~sour mash process is not exclusive~~ to ~~bourbon production, it is a hallmark~~ of ~~the style. To be labeled as bourbon,~~ a ~~whiskey must meet several specific criteria, including being produced~~ in the ~~United States, made from a grain mixture that is at least 51% corn, and aged in new, charred oak barrels~~. The ~~use of the~~ sour mash process is ~~not a legal requirement for bourbon, but it is widely used~~ in the ~~industry for its benefits to flavor~~ and ~~consistency~~.

	==~~Conclusion~~==		== Benefits ==
	The sour mash process is a traditional method in whiskey production that has played a significant role in the development of distinctive spirits, especially bourbon. Its use of a portion of spent mash to initiate fermentation in a new batch helps to ensure consistency, enhance flavor, and improve efficiency in the distillation process.

			The primary benefit of the sour mash process is the consistency it provides in the flavor of the whiskey. By using a portion of the previous mash, distillers can ensure that each batch of whiskey has a similar taste and quality. This is especially important for brands that rely on a specific flavor profile to maintain their reputation.

			Additionally, the sour mash process can help to reduce the risk of contamination by harmful bacteria, as the acidic environment created by the backset inhibits their growth.

			== History ==

			The sour mash process has been used in whiskey production for centuries. It is believed to have been developed in the early 19th century by Dr. James C. Crow, a Scottish chemist who worked in the American whiskey industry. Dr. Crow's innovations in the distillation process, including the use of sour mash, helped to improve the quality and consistency of American whiskey.
