Craft Brew Alliance is a beer brewing company that is composed of five beer and cider brands:

According to the Brewers Association, it is the 9th largest beer brewing company in the United States, based on 2012 sales volume of 724,900 and an annual working capacity of approximately 1,075,000 barrels.

As of January 2013, Anheuser-Busch InBev owned 32.2% of the business and is also the company's distribution partner, has two seats on its board of directors, and special status in the company's board committees. As of August, 2010, Brothers Kurt and Rob Widmer, founders of Widmer Brothers beer, owned a combined 18%.

The company was formed on July 1, 2008, with the merger of Redhook Ale Brewery and Widmer Brothers Brewery. CBA acquired Kona Brewing Company on October 1, 2010. In 2012, CBA launched a new brand called "Omission" beer, promoting the beer as specially crafted to remove gluten. In 2013, CBA launched a cider - Square Mile Cider, and in 2014 entered into a partnership with The Chive to create KCCO beer under the independent/Chive-owned Resignation Brewery moniker.

The company was originally named Craft Brewers Alliance, but changed its name to Craft Brew Alliance on January 12, 2012.

As of March 15, 2012, Craft Brew Alliance is publicly traded as NASDAQ: BREW. Prior to this date it was publicly traded as HOOK.

The company produces brands such as Redhook, Widmer Brothers Brewing, Omission Beer and several others.

On November 21, 2013, the company announced that, effective January 1, 2014, Andy Thomas will take over as the company’s new CEO.

On May 20, 2015, CBA announced the appointment of Joe Vandersteldt to CFO, along with several other changes at the executive leadership level.

Redhook was founded in the early 1980s in Seattle. At first, the brewery was a small shop in the Seattle neighborhood of Ballard. The beers brewed by Redhook include ESB, IPA, Pilsner, Copperhook, and seasonal brews.

Widmer Brothers brews various beers including their flagship, Hefe American Hefewiezen, Drop Top Amber Ale, Upheaval IPA, Steel Bridge Porter, PDX Pils, various seasonals and 10+ small batch beers on tap at the Brewery on Russell St.

The Kona Brewing Company was founded in the spring of 1994 and is Hawaii's largest brewery.

The company's Omission beer is designed to have low gluten content by using a proprietary enzyme to remove gluten from traditional beer ingredients - namely malted barley.

Launched in 2013, there are two primary products under this brand - "The Original" which is a traditional hard apple cider; and "Spur & Vine", which is a "hopped apple cider".

On December 2, 2014, CBA entered into a strategic partnership agreement with Boone, NC-based Appalachian Mountain Brewery (AMB). As part of the partnership, CBA will act as "master distributor" for AMB, allowing their products to ship via the Anheuser-Busch InBev distributor network. CBA has taken an undisclosed, minority stake in AMB.

On September 25, 2015, CBA announced a strategic partnership agreement with Nantucket-based Cisco Brewers. As with previous partner, AMB, CBA will act as "master distributor" for AMB, allowing their products to ship via the Anheuser-Busch InBev distributor network. CBA has taken an undisclosed, minority stake in Cisco Brewers.

On December 15, 2016, CBA announced a strategic partnership agreement with Miami, FL-based Wynwood Brewing. CBA is taking a 24.5% stake in Wynwood, valuing the deal at under $30 Million. As with previous partners, AMB and Cisco Brewers, CBA will act as "master distributor" for Wynwood, allowing their products to ship via the Anheuser-Busch InBev distributor network.

While the company name contains the phrase "craft brew", it does not meet the definition of a craft brewer according to the Brewers Association, due to the percentage stake owned by Anheuser-Busch InBev. The Brewers Association defines American craft brewers as "small, independent and traditional", with 'small' defined as an "annual production of 6 million barrels of beer or less", a limit changed in 2011 from 2 million to 6 million to ensure the ongoing inclusion of Boston Beer Company (the producer of the Samuel Adams brand), 'independent' defined as at least 75% owned or controlled by a craft brewer, and 'traditional' defined as at least 50% of its volume being all malt beer.
