The Mittagong Maltings Works was originally established by the Maltings Company of NSW (Ltd) and operated from August 1899. Tooth and Company Limited purchased the Mittagong Works in 1905 and produced the malt used in Tooth & Co breweries in Sydney. The early 1940's was an active period, with output of malt being approx 200,000 bushells annually. This output was severely restricted following a large fire in August 1942, which completely gutted No.2 Malthouse and damaged No.1. The No.1 Malthouse was returned to service early in 1943. The No.2 Malthouse was completely rebuilt during the early 1950's and recommenced active operation in 1953. Operation continued normally until another fire gutted the No.3 Malthouse in 1969. Tooths & Co continued to operate at the site until 1980, when the works were closed and the site sold to a group of local business people.
