sour mash whiskey
Noun: A type of American whiskey, particularly bourbon or Tennessee whiskey, produced using a specific fermentation process. This process involves using a portion of previously fermented mash (called "sour mash") to start the fermentation of a new batch, which helps control pH levels and ensures consistency in flavor and quality across different production runs.
The term "sour mash whiskey" specifies the production method. It is used to describe the category, not a brand. * Most major brands of Kentucky bourbon are sour mash whiskey. * The distillery is known for its traditional sour mash whiskey process.
- The term can be used attributively (like an adjective) to describe the process itself, as in "sour mash process" or "sour mash method."
- In discussions of whiskey production, "sour mash" is often contrasted with "sweet mash," which uses entirely fresh yeast for each fermentation.
- Sour mash (noun phrase): The mash or the process itself. Example: "They use a sour mash to ferment the grain."
- Bourbon (noun): An American whiskey made from a grain mixture that is at least 51% corn and aged in new charred oak barrels. Most bourbon is made using the sour mash process.
- Tennessee whiskey (noun): A straight whiskey produced in Tennessee, filtered through maple charcoal before aging (a process called the Lincoln County Process). It is also typically a sour mash whiskey.
- Sour mash bourbon (when referring specifically to bourbon made by this process).
It is important to distinguish the general term "sour mash whiskey" from specific brand names. For example, "Jack Daniel's" is a brand of Tennessee whiskey that is a sour mash whiskey, but "sour mash" is not its brand name. The definition emphasizes the process of distillation from a sour mash, not a specific flavor profile (e.g., "sour" taste).
