The early German settlers quickly established a brewery in Formosa, in 1870. Over the years, the brewery has changed ownership and names many times, and the plant itself changed with renovations, expansions, and reconstructions. In 1922, the brewery's Buffalo-based owners closed the plant, due to prohibition. In 1924, it reopened as the Formosa Spring Brewery and a program of modernization was undertaken. Beer began to be produced again in 1927, and the brewery operated continually in Formosa from then on to the closure of the plant at the end of 1971. The summers of 1958 and 1968 were of special note in the history of the brewery; strikes by unionized beer workers shut down beer sales everywhere else in Ontario. Crowds of thirsty Ontario beer drinkers flocked to Formosa, where rationing of one case per customer had to be instituted at times. In the late 1960s, the plant had reached bottling capacity, and the Formosa site was deemed infeasible for expansion. The owners built a new plant in
Barrie, Ontario, and moved operations there, still under the 'Formosa Spring Brewery' name. In 1974,
Molson's purchased the Barrie-based Formosa Spring Brewery, renaming it Molson's Brewery. The Formosa plant was sold and used for a number of years for other industries such as water bottling and fish farming. With the rise of
microbreweries in Ontario in the 1980s and 1990s, the Formosa plant was once again put to use brewing beer. The Algonquin Brewing Company purchased the plant in 1988, and restarted brewing operations in Formosa. They put out a few different varieties of beer, including some they labelled 'Formosa Springs'. The company was subsequently sold to the
Brick Brewing Company in 1997, who retained the 'Formosa Springs' label on a few varieties. In January 2017, Brick put the small company up for sale. On September 7, 2017, Brick Brewing confirmed the completion of the Formosa sale. Brick confirms that the sale transaction closed on September 6. In the winter of 2017, the new owners quickly moved in, installing new equipment, hiring previous employees back, re-opening the brewery beer store and implementing a new commercial craft beer strategy. ==Special events==
