Hibernia Brewing Ltd. was an American brewery company, the successor firm to the Walter Brewing Company, located in Eau Claire, Wisconsin.  Under the leadership of Michael Healy, president and chief stockholder of Hibernia, the brewery introduced several specialty brews considered innovative for their time and became one of the first producers in the American Midwest of what now are considered to be craft beers and ales.  At its peak, Hibernia produced over 30,000 barrels of beer per year, employed about 50 workers, and had a market range that included Minneapolis–Saint Paul, St. Louis, Missouri, and Omaha, Nebraska, with success also in Denver and Boulder, Colorado to the west and south; and Chicago, Milwaukee, and suburban Cleveland, Ohio to the east.  The brewery quickly earned a reputation for quality products, aided by the receipt of a second place award for its Hibernia Dunkel Weizen in the Great American Beer Festival of 1985.  However, the release of underpasteurized beer to new markets was an economic disaster.  Although the brewmaster and assistant brewmaster were fired immediately and insurance covered the recall, it was impossible to get the consumer to give them a second chance.  This combined with increasing competition from the growing number of companies passing themselves off as brewers, when in fact they were sales/marketing entities that outsourced the manufacturing of their beers.
