" Period Three. Prohibition 1918 - 1933
In the two years leading up to the start of Prohibition, San Antonio and Texas in general, was in its prime. San Antonio boasted six breweries: the San Antonio Brewing Association; Peter Bros Brewery; Degen’s Brewery; the Lone Star Brewing Association, Schober’s; and the Och’s and Aschbacer’s Brewery. 1916 saw these San Antonio breweries realize a combined annual income of $8,000,000 that was a ridiculously high sum that amounted to around a fourth of the city’s overall income. With 1,200 employees and a total payroll of a million, San Antonio’s brewing Industry was three times larger than any other industry in the Alamo City. In 1917, with Prohibition on the horizon, the San Antonio Brewing Association introduced ‘La Perla – A Near Beer’ while still brewing XXX Pearl Beer.
