Crushing grapes is a process used in winemaking to extract juice from the grapes. The term 'crush grapes' can be found in literature, such as AESOP's fables, and is also referenced in the popular phrase 'stomping grapes'. In the 1930s, during the Great Depression, many people in Oklahoma, known as 'Okies', were forced to crush grapes for wine production due to the lack of other job opportunities. The resulting wine was often SOUR due to the lack of resources available to the Okies.
