During the Prohibition era of the 1920s and 1930s Traphill became a center of the mass production and exportation of illegal homemade liquor, or moonshine. Moonshine became the main source of income for many Traphill families, and until the 1980s, the town continued producing over a million gallons of white liquor each year. Traphill residents made sugar and grain liquor for sale and fruit "brandy" for personal consumption, and continue to do so, with apple and peach brandies being the most common. From the 1920s to the 1960s Federal tax agents, state police units, and local police all patrolled the hills and hollows looking for moonshine stills.
