By 1977, Pittsburgh Brewing Company was one of just 40 breweries left in the country. To rebound from difficult years, the brewery introduced a new light beer, Iron City Lightâor IC Light. IC Light's aggressive marketing campaign targeted the young beer drinker.
Introduced last fall to upstate New York and Massachusetts, Mount Royal Light now also is being distributed in such other markets as Colorado, Tennessee and Wisconsin. This new specialty liquor contains Canadian whiskey. Seagram also gives a good report card (``it`s done fabulously well so far``) on Mount Royal Light.
