Forst is an Italianbrewing company, based in Forst (Italian: Foresta), a frazione (municipal subdivision) of Algund (Italian: Lagundo), South Tyrol. The brewery was founded in 1857 by two entrepreneurs, Johann Wallnöfer and Franz Tappeiner, from Meran (Italian: Merano). Later in 1863, the company passed to the entrepreneur Josef Fuchs, who enlarged the plant in Forst. In 2004, Forst opened a small micro-brewery in Forst, Germany.
Forst has an annual production of 700,000 hl, serving primarily the domestic market. In 1991 it additionally acquired the Brewery Menabrea in Biella, Piedmont and also maintains a bottling plant in Palermo, Sicily. The company produces also mineral water and other non-alcoholic drinks, through a subsidiary named Kaiserwasser.
