Agassiz putting its hopes in its Soo-brewed products
A report from the Winnipeg Free Press stated:
Ontario-brewed, Agassiz Brewing Co.'s beer will hit Manitoba liquor-store and vendor shelves this week. Agassiz Brewing Co. was recently been resurrected as New Manitoba Brewing. Late last year, Agassiz Brewing Co. was forced to shut its doors and sell its brewing equipment following a cash crunch resulting from low sales and high overhead costs. Shortly after, New Manitoba Brewing purchased Agassiz's brands and recipes and signed an agreement to outsource the production of its beers to Northern Breweries Inc. in Sault Ste. Marie.
In addition, their entry at beerme.com
lists them as a "Beer Marketing Company" and "Formerly a microbrewery", with Northern listed as their brewer. The listing was last updated in February, 2004.
