Leinenkugel's

Leinenkugel's is the operating name of the Jacob Leinenkugel Brewing Company, a Wisconsin beer maker founded in Chippewa Falls in 1867 by Prussian immigrant Jacob Mathias Leinenkugel and John Miller. The brewery is regarded as the seventh-oldest brewery in the United States and the oldest continuously operating business in Chippewa Falls. Its early beers were based on a German brewing formula brought by Leinenkugel, and the company initially built its reputation as a regional producer of conventional lagers and ales. The business remained family controlled for more than a century. Miller sold his interest in 1884, leaving the Leinenkugel family to operate the brewery. Prohibition forced the company to diversify into near beer and soda water. After repeal, members of the Leinenkugel family mortgaged their homes to finance the restoration of brewing equipment, helping preserve the company through a difficult transition. The brewery began expanding beyond its traditional regional base in the 1970s, including the introduction of a light beer. Facing financial pressure, the family sold the brewery in 1988 to Miller Brewing Company, then a subsidiary of Philip Morris. The transaction was notable because Miller retained members of the Leinenkugel family in management rather than completely replacing the established operating structure. Leinenkugel's continued to be presented as a regional, heritage-oriented brewery while benefiting from the distribution and marketing resources of a major beer company. The brand's largest modern growth opportunity came with the launch of Summer Shandy in 2007. The beer combines a wheat-based or ale-style brewing profile with lemonade-like citrus character, helping establish shandies as a significant seasonal category in the United States. Leinenkugel's subsequently expanded its fruit-flavored, citrus, and seasonal portfolio and became particularly associated with sweeter, approachable beers. The brand historically concentrated on the Upper Midwest but later achieved distribution across all 50 states. Leinenkugel's also operates as a visitor and heritage brand. The Chippewa Falls site has offered brewery tours, while the nearby Leinie Lodge provides a tasting room, retail merchandise, and a pilot brewery for small-batch production. The company has used its family history and Wisconsin identity as important parts of its consumer positioning. For its 150th anniversary, it released an old-style German beer brewed under license in Germany by Hofbräu. The brewery became part of the Molson Coors portfolio after the corporate transactions involving MillerCoors and SABMiller. In 2016, following Anheuser-Busch InBev's acquisition of SABMiller, Molson Coors became the sole owner of the Miller brands, including Leinenkugel's. The Chippewa Falls brewery and Milwaukee's 10th Street Brewery were subsequently affected by operational consolidation. Molson Coors announced in November 2024 that both facilities would close by January 17, 2025, with production consolidated in Milwaukee or elsewhere within the company network. The Chippewa Falls site nevertheless continued to support tours and heritage activities according to the supplied reference material. In January 2026, Katie Leinenkugel was identified as the sixth generation of the family to head the brewery.

Leinenkugel's traces its history to May 1867, when Jacob Mathias Leinenkugel and John Miller co-founded a brewery in Chippewa Falls, Wisconsin. Leinenkugel, a Prussian immigrant, brought a German-influenced brewing formula that formed the basis of the company's early production. Miller later sold his stake in 1884, leaving the brewery under Leinenkugel family control. The enterprise became both a major local institution and the oldest operating business in Chippewa Falls. The brewery survived Prohibition by making near beer, locally known as "Leino," and soda water. After the repeal of Prohibition, members of the Leinenkugel family mortgaged their homes to fund the rehabilitation of the brewery's brewing vats. This episode became part of the brand's family-continuity narrative. For much of its early modern history, the company was primarily a regional Upper Midwest brewer, with traditional beers representing the bulk of its production. Expansion began in the 1970s, including the introduction of a light beer. In 1988, financial difficulties led the family to sell the company to Miller Brewing Company, a Philip Morris subsidiary. Miller preserved a degree of continuity by retaining Leinenkugel family members in the operation. Several attempts were made to broaden distribution, but the brand's strongest growth came after the 2007 introduction of Summer Shandy. Its combination of beer and lemonade-style citrus flavor gave Leinenkugel's a distinctive position in the growing seasonal and flavored-beer segments. The company later developed a broader shandy and fruit-beer portfolio while retaining conventional lagers and ales. Its distribution expanded from the Upper Midwest to all 50 states. Leinenkugel's also acquired Milwaukee's 10th Street Brewery in 1995. The facility had previously been associated with the Valentin Blatz Brewing Company and was opened in 1986 by G. Heileman Brewing Company for the Blatz label. Under Leinenkugel's ownership, it became associated with the Big Eddy line of seasonal, higher-alcohol ales. Corporate ownership changed again through the MillerCoors and SABMiller transactions. In 2016, after Anheuser-Busch InBev acquired SABMiller and SABMiller sold its stake in MillerCoors, Molson Coors became the sole owner of the Miller brands, including Leinenkugel's. The brand continued to emphasize its family history, Wisconsin roots, visitor experiences, and accessible flavored beers. Its 150th anniversary was marked with an old-style German beer brewed under license in Germany by Hofbräu. Labor and production changes shaped the brand's later history. Workers represented by Teamsters Local 662 struck in July 2023 over wages, ending the action on September 1 after ratification of a three-year contract. In November 2024, Molson Coors announced plans to close both the historic Chippewa Falls brewery and the 10th Street Brewery by January 17, 2025, consolidating production. The Chippewa Falls location continued to be associated with tours and the Leinie Lodge visitor operation. In January 2026, Katie Leinenkugel became the sixth generation of the family to head the brewery.
