Besides its Canadian connection (sometimes sporting a picture of a Mountie on cans or labels), the main Drewrys claims to fame were that the beer was "less filling – more satisfying!", years before the popularity of light beers, and also (with the advent of lighter aluminum cans) that a can of Drewrys would actually float in water, rather than sinking to the bottom of a bucket or tub.
The South Bend based brewry was merged with Associated Brewing in 1965, making the Associated/Drewrys plants the 10th largest brewry in the U.S. The plant was sold to G. Heileman brewing of Lacrosse Wi. in 1972. Heileman chose to close the plant. The last cases of beer left the plant in November 1972. Heileman owned the brand until it was sold to the Evansville Brewing Co, of Evansville In. This plant was closed in 1996 and the brand was bought along with others by Pittsburgh Brewing co.
