SOUR MASH Meaning and
Definition
-
Sour mash is a term commonly used in the realm of distilling, particularly in the production of bourbon whiskey. It refers to a specific fermentation process where a portion of the previous batch of mash (a mixture of grain and water) is added to the new batch to start the fermentation process. This technique is used to ensure consistency in flavor and maintain a stable pH level in subsequent distillations.
The sour mash process begins by cooking a mixture of grains, typically corn, barley, and rye, in water to extract sugars. Once cooled, yeast is added to the mash to trigger fermentation, where the yeast converts the sugars into alcohol. At this stage, a portion of the fermented mash, called the "backset" or "stillage," is retained and mixed with the newly cooked mash in the next batch. The acidic nature of the backset helps control the growth of unwanted bacteria and promotes a healthier yeast environment. The addition of the backset also contributes to the development of unique flavors associated with sour mash whiskeys.
Sour mash is a crucial step in traditional bourbon whiskey production, as it imparts distinctive characteristics to the spirit, offering a balanced acidity and depth of flavor. It has become a defining feature of many American whiskies and is regulated by law for bourbons to be labeled as such. Overall, sour mash represents a time-honored method used to create consistent, flavorful, and high-quality whiskeys.

Etymology of SOUR MASH
The term "sour mash" has its origins in the production of bourbon whiskey. The word "sour" refers to the souring or acidification of a previous batch of mash, which is fermented grain and water mixture used to produce alcohol. The method involves using a portion of the spent mash, known as "backset" or "stillage", from a previous batch to start the fermentation of a new batch. This backset contains lactic acid, which contributes to the sour flavor. The term "mash" comes from the Old English word "mæsce", which means "soft mixture" or "mash". Together, "sour mash" describes the process of reusing a portion of the previously fermented grain mixture to inoculate a new batch, contributing to the distinctive flavor of bourbon whiskey.
