The desire of the governing class of colonial New South Wales to reduce drunkenness among the working classes coincided with the desire to create a wine industry. This intersection occurred in legislation encouraging substitution of light wine for beer and spirits. The notion that encouraging production and consumption of colonial wine could create sobriety arose from faith in the transformative qualities of wine. This faith can be traced from influential philosopher Adam Smith's conviction in Wealth of Nations (1776) that people who lived in proximity to wine regions in France were among the most sober Europeans to the enactment of a policy of substitution in the New South Wales Parliament in the 1860s.
