Morphology

sour + mash

The compound is partly compositional: a B1 learner who knows 'sour' (fermented/acid) and 'mash' (crushed grain mixture) can infer a ‘mash that is sour’ and thus likely a type of whiskey made from such a mash. However, the specific production detail (that part of a previous batch is used to start fermentation) is a technical, culture-specific process not predictable from the constituents alone, so the term is only partially transparent.

Etymology

The noun sour mash comes from a simple way of making whiskey: makers save some old, slightly sour mash (the wet grain mix) and add it to a new batch to help it start fermenting. That's why sour mash now means 'a way of making whiskey' or the 'whiskey made this way'.
