Pittsburgh Brewing Company, previously known as Iron City Brewing Company, is a beer manufacturer based in Pittsburgh, Pennsylvania’s Lawrenceville district. The company is recognized for its portfolio of beers including Iron City Beer, I.C. Light, I.C. Light Mango, Old German, and Block House Brewing. Brewing took place at its Lawrenceville site until August 2009; thereafter, production was outsourced to City Brewing Company’s facility—previously the producer of Rolling Rock—from 2009 through 2021. On February 4, 2021, the company declared the resumption of in-house brewing at a newly established brewery located in Creighton, Pennsylvania, within the historic Pittsburgh Plate Glass Company building, with an initial annual output capacity of 150,000 barrels.
History
Established in 1861 by Edward Frauenheim, a German immigrant, Iron City Brewery was one of the earliest American breweries to specialize in lager beer production. It expanded rapidly alongside Pittsburgh’s industrial growth. By 1866, the brewery moved into a four-story brick structure at Liberty Avenue and 34th Street valued at $250,000 and further extended its facilities three years later by adding a three-story building.
Equipped with state-of-the-art brewing technology for the time, the brewery employed 25 full-time skilled workers out of a total workforce of 30. Over time, it grew to become Pittsburgh’s largest brewery.
Leopold Vilsack, a native of Pittsburgh who trained at Bennett Brewery, joined Frauenheim’s enterprise after the 1866 expansion and entered into partnership upon Miller’s retirement. The firm was subsequently renamed Frauenheim and Vilsack Company.
By the late 1800s, Iron City Brewery had an annual production capacity near 50,000 barrels, ranking it among the largest breweries nationwide and holding a dominant position west of the Atlantic seaboard. Its assets—including inventory and raw materials—were valued at approximately $150,000, a substantial sum at that period.
By 1886, the brewery operated around 500 sizable reception casks each holding between 45 and 50 barrels and maintained a circulating inventory of roughly 10,000 kegs.
Regional trust
During the late nineteenth century, industry trusts emerged as strategic alliances designed to secure stability and benefit from economies of scale within brewing. On February 3, 1899, twelve breweries from the Pittsburgh area sought license transfers to establish the Pittsburgh Brewing Company. This consolidation eventually incorporated 21 breweries across Pennsylvania. The merger formed the state’s largest brewing enterprise and ranked third nationally in size—with assets valued near $11 million and an annual capacity exceeding one million barrels. This unification enabled investments in modern equipment and operational efficiencies.
Throughout Prohibition (1920–1933), Pittsburgh Brewing Company survived by diversifying into non-alcoholic products such as soft drinks and ice cream, producing near beer, and offering cold storage services—maintaining its market presence while many competitors ceased operations.
Post-prohibition
After Prohibition ended, Pittsburgh Brewing recruited expert leadership to restore its core brewing operations. Peter Zugel assumed brewmaster duties drawing on experience acquired during Prohibition through family connections and focused on quality-driven production until his retirement in 1973.
During the 1970s, Pittsburgh Brewing expanded by acquiring Queen City Brewing Company in Cumberland, Maryland along with its subsidiaries. Although Queen City closed in 1974 due to labor disputes and declining sales, Pittsburgh Brewing inherited several brands including Old German and Gamecock Ale. Additionally in 1974, it purchased Augustiner, Mark V, Robin Hood, and Gambrinus brands from Ohio-based August Wagner Breweries.
By 1977, Pittsburgh Brewing was one of only 49 remaining breweries operating in the United States. To reclaim market share amid industry pressures, it introduced Iron City Light (IC Light), aimed at younger demographics with vigorous marketing campaigns. IC Light rapidly secured approximately 80% of the local light-beer market segment and increased sales of traditional Iron City beer throughout southwestern Pennsylvania.
In 1986, Australian businessman Alan Bond acquired Pittsburgh Brewing through Bond Brewing Holdings Ltd., integrating it with G. Heileman Brewing Company by 1988. Financial setbacks compelled Bond to sell Heileman in 1991 and divest Pittsburgh Brewing in 1992 to entrepreneur Michael Carlow’s Pittsburgh Food & Beverage Company.
Carlow’s management ended amid fraud charges that resulted in imprisonment. Following this period, local investor Joseph Piccirilli purchased Pittsburgh Brewing in 1995 for $29.4 million via Keystone Brewing Company. Piccirilli sought to modernize operations introducing innovations such as aluminum bottles but encountered labor disputes and declining sales volumes. By 2005 production had dropped below 400,000 barrels annually despite previously reaching historic highs near one million barrels—leading to a Chapter 11 bankruptcy filing.
Brand Revival
In 2007, Unified Growth Partners purchased the brewery following bankruptcy proceedings, reinstating its original title, "Iron City Brewing Company," and launching efforts to restore full-scale production.
By May 2009, Iron City Brewing formed a collaboration with City Brewing Company to make use of the former Rolling Rock Latrobe Brewing Company facility. Brewing operations recommenced in June, followed by bottling and kegging starting in July 2009.
In 2018, Pittsburgh Brewing—the producer of Iron City Beer—was acquired by Rosebud Mining, which took ownership of the Lawrenceville plant with intentions to refurbish the historic blockhouse structure. Renovation work began in 2019 to rejuvenate this copper-accented landmark.
As of 2023, brewing activities have resumed at the former PPG Industries Works 1 site in Creighton, PA, which had ceased operations in 2018 and is now managed by Rosebud. Additionally, a distillery was established on the premises, broadening the company’s range of products.
Products
The core offerings from Iron City Brewing Company consist of Iron City Beer—a traditional lager with a macro-style profile—and IC Light. Their lineup also includes American, American Light, Old German, and Blockhouse Brands, the latter representing their craft beer selection. In June 2011, the company introduced IC Light Mango. The product range further expanded in summer 2019 with the launch of IC Pumped Mango (8.0% ABV), along with IC Light Twist Cherry and IC Light Twist Lime Coconut variants.
Historically, Iron City held brewing rights for Wiedemann beer and produced Samuel Adams under contract for the Boston Beer Company during its formative years.
