US craft brewer Full Sail Brewing is being sold to a group led by private equity firm Encore Consumer Capital, according to local reports. 

The Oregon-based brewer's 78 employee-shareholders have voted unanimously in favour to sell their controlling interest for an undisclosed sum, The Oregonian has reported. Full Sail's CEO, Irene Firmat, told the website that the company expects to take on more sales staff once the deal closes. 

Full Sail was founded in 1987 in Hood River, Oregon. Its beers include Full Sail Amber, an IPA and a Pilsner.

San Francisco-based Encore Consumer Capital has investments in a variety of consumers product companies in the US.

A number of other US craft brewers - including Southern Tier and Uinta - secured deals with private equity firms last year in a bid to capitalise on the rapidly-expanding sub-category.
