The Keweenaw Brewing Company (KBC) is a craft brewer with a taproom in Houghton and a production facility in nearby South Range, Michigan.

It was founded by Paul Boissevain and Richard Grey, who previously worked at the same oil company in Denver, Colorado, and lost their jobs around the same time.

[1] Keweenaw was the second modern microbrewery in the Upper Peninsula, after Hereford & Hops Steakhouse and Brewpub, and opened over three decades after Houghton's last brewery (Bosch) closed in 1973.

[16] Boissevain retired and sold his share of the business to his partner Grey, who in turn brought on his son and son-in-law as co-owners.

[22] As of 2019[update], the interior space at Keweenaw's Houghton brewpub measured 3,400 square feet (320 m2) and contained two bars and a fireplace.

"[25] As of 2019[update], the most popular beer sold by the Keweenaw Brewing Company is Widow Maker Black Ale, whose name stems from a dangerous one-person drill once used in service of the region's extensive copper mining.
