Diamond Knot Brewing Company

History
Diamond Knot Craft Brewing was established in October 1994 by two Boeing employees. The two handled all production and distribution in the evenings over the first four years out of subleased space in an alehouse. In March 1999, the alehouse was acquired. It was improved to increase capacity to about 1,200 barrels a year. The brewery was not able to meet demand. Capacity was quadrupled in 2005 with the opening of a 4300 sqft facility.

Beers
According to The Seattle Times, the brewery is "widely regarded as producing some of the best, most innovative beers in the region". The India Pale Ale is the brewery's flagship beer. Diamond Knot has also produced a stronger "Industrial XIPA". The Brown Ale is another popular selection.
