For Immediate Release

April 19th, 2018 - Calgary, Alberta - Big Rock Brewery Inc. (TSX: BR) ('Big Rock') and Fireweed Brewing Corp. ('Fireweed') today announced they have entered into a joint venture agreement.

The primary market focus will be in British Columbia where Big Rock's Vancouver brewing facility will be operated under a contractual joint venture agreement.

Production of Fireweed products for the Alberta market will be handled under a contract manufacturing agreement.

'This is an incredible opportunity to expand the Vancouver brewery and leverage the many strengths of both Big Rock and Fireweed Brewing Corp, a well-respected BC-grown business,' says Wayne Arsenault, President and CEO of Big Rock Brewery.

'Combined, we have over half a century of Canadian craft brewing experience, and while we will remain independent businesses I look forward to working with Fireweed to drive cost efficiencies and further grow our brands,' says Arsenault.

Among Fireweed Brewing Corps beverage brands are Tree Brewing, Dukes Cider and Shaftebury.

Tod Melnyk, President and CEO of Fireweed commented, 'In the fast pace competitive craft beer environment, craft brewers must look for new ways to be sustainable, relevant and profitable. We believe this joint venture is a model for the future and we are excited to work with the Big Rock team to grow our businesses.'

The agreement is expected to become effective on May 31, 2018, with joint venture operations to commence in June 2018.
