Back in 2008 the Brainerd Lakes Brewing Company launched and began contracting with the Lake Superior Brewery to make their brand of beers. At the time Lake Superior Brewing was one of the first small brewers in a growing landscape of independent breweries in Minnesota. It appears that Brainerd Lakes Brewing Company isn’t the only one to become a thing of the past.

In Duluth since 1994, Lake Superior Brewing was the longest-running microbrewery in the city. Recent news reports appears that they have closed their business at 2711 W. Superior St., Duluth.

There was no announcement of the closure on its social media pages, nor on its website. The brewery produces a number of beers, including its Riptide IPA, Kayak Kolsch Style, and Mesabi Red Ale, as well as a contract brewer for some other brands like the former Brainerd Lakes Brewing.

December 1st was the last update on its Instagram page, announcing they were closing for the day due to the huge snowstorm in the twin ports. But the Duluth News Tribune reports that the brewery has now been locked since at least late November, with the brewery’s landlord, King Properties, confirming it had shut down. The reason for its closure remains a mystery, with the owners declining to comment when asked by the News Tribune.
