Golden Sheep Ale, first launched in 2009, is the company’s premier brand in the golden ale market.
The new label is designed to offer a more fresh and modern look for the ale. It will appear in stores from November.
Black Sheep successfully rebranded its core Black Sheep Ale last year.
Jo Theakston, sales and marketing director at the Black Sheep Brewery, said: “The re-branding of Golden Sheep comes as we look to create a ‘family feel’ to our bottled beer range.
“The bold re-brand of Black Sheep Ale last year helped push sales forward and we are hoping Golden Sheep Ale will experience a similar surge.
“The new branding stands out really well on supermarket shelves and we hope to pull in more new drinkers to this quality drop as a result of taking this step.
“There is strong growth in the golden ales market, which is proving a strong entry point for drinkers getting into ales for the first time, and Golden Sheep Ale is a perfect place to start.”
The Black Sheep Brewery was founded by Paul Theakston in 1992.
Sales at the Masham brewery hit £19.5 million last year, slightly below its 2012 high of £19.9 million.
The company recorded a small loss of £34,000 last year, the third year in a row in which it had failed to make a profit.
It is expected to return to profitability in the current financial year.
